A force of 45 N is exerted on an object, resulting in an acceleration of 5 m/s2 for the object. What will the object's acceleration be if the force doubles? Question 3 options: 2. 5 m/ s2 5 m/ s2 10 m/ s2 20 m/ s2.
Answers
The acceleration will be 10 m/s² if the force is doubled. Option C is correct.
What is Force?It can be defined as the product of the mass of the object and its acceleration.
\(F = m a \)
Where,
\(F\) - force = 45 N
\(m\)- mass = ?
\(a\) - acceleration = 5 m/s²
Now, put the values in the formula,
\(45 = m \times 5 \\\\ m = \dfrac {45 }{5}\\\\ m = 9\rm \ kg \)
Now if force doubled then the acceleration will be
\(a = \dfrac {2 \times 45} {9}\\\\ a = 10 \rm \ m/s^2 \)
Therefore, the acceleration will be 10 m/s² if the force is doubled.

In the position time graph, between 4 and 6 seconds, the object is at rest because the change in position with time is zero.
What is position - time graph?
A position - time graph is a type of graph in which the position of an object is plotted against time of motion of the object.
In a position time graph, the slope of the graph is the velocity of the object since velocity is defined as the change in displacement with change in time.
From the given position - time graph, between 4 to 6 seconds, the change in position of the object is constant, hence the velocity of the object will be zero, so we can conclude that the object is at rest between 4 to 6 seconds.

Squared. (13-59 mod.) Four identical stars of mass M form a square that rotates around the square's center as the stars move in a common circle about that center. The square has edge length L. What is
Answers
The squared quantity is 4(2L/π)².
To calculate the quantity you're asking for, we'll first determine the distance of each star from the center of rotation. Let's assume the stars are labeled as A, B, C, and D.
The center of the square is equidistant from all four stars. Let's denote this distance as R.
Since the stars are arranged at the corners of a square, the diagonal of the square is twice the distance from a corner to the center. Therefore, the diagonal of the square has a length of 2R.
Now, let's consider the diagonal of the square as the diameter of the circle in which the stars move. The circumference of a circle is given by the formula:
C = 2πr
where C is the circumference and r is the radius of the circle.
In this case, the circumference of the circle is equal to the perimeter of the square, which is 4L. Therefore:
2πR = 4L
R = 2L/π
Now, to calculate the squared quantity you're interested in, we can find the sum of the squares of the distances of the stars from the center:
Sum = (Distance of star A)² + (Distance of star B)² + (Distance of star C)² + (Distance of star D)²
Since all four stars are equidistant from the center, we can calculate the sum as:
Sum = 4R²
Substituting the value of R we found earlier:
Sum = 4(2L/π)²
Therefore, the squared quantity you're looking for is 4(2L/π)².

Explain the difference between dominant and recessive genes, and provide an example of each one.
Answers
When an allele is recessive the characteristics it is connected to is less likely to be expressed. Recessive traits only manifest when both alleles are recessive in an individual.
Example:
On dominant, Brown eyes trait, A and B bloods type
Recessive, blue eyes trait, O blood type.
Father Brown blue
Mother Brown blue
1 kid = BB
2kid = Bb
3 kid = Bb
4 kid = bb
The dominant allele B will take over recessive allele b.
So if both of your parents have dominant Brown eyes and recessive blue eyes it’s 75% likely that one of four siblings will have brown eyes and 25% will have blue.
Answer:
Dominant genes are genes that are most likely to be adapted to offspring. Recessive genes are genes that are least likely to be adapted to offspring. For example, if the father had brown eyes and the mother had green eyes, their offspring will most likely have brown eyes because brown eyes are considered dominant and more likely to happen.

A rock with a mass of 10. 0kg falls 25. 0m to
the ground. What is the work done by the
gravitational force if the weight of the ball
is 98. 0N?
Answers
Answer:
Explanation:Potential Energy is the stored energy of an object given its position relative to a body. Gravitational potential energy is one type of potential energy and is equal to the product of the object's mass (m), the acceleration caused by gravity (g), and the object's height (h) as distance from the surface of the ground (the body).
mass m of 3 kilograms falling at gravity g of 9.81 meter per second squared from a height h of 5 meters. Solve for potential energy Pe with the equation PE equals m times g times h
In this example, a 3 kilogram mass, at a height of 5 meters, while acted on by Earth's gravity would have 147.15 Joules of potential energy, PE = 3kg * 9.81 m/s2 * 5m = 147.15 J.
9.81 meters per second squared (or more accurately 9.80665 m/s2) is widely accepted among scientists as a working average value for Earth's gravitational pull. This figure is based on a measure of gravity at sea level at a latitude of 45°.
At higher altitudes, gravity decreases slightly.
The effect of latitude on gravitational force is relevant as gravity increases with increasing distance from the Equator. At the Equator, the Earth's gravity is 9.780 m/s2 and at the poles it is 9.832 m/s2 (source: CRC Handbook of Chemistry and Physics).
Gravitational acceleration (to three significant figures) for other planets and bodies in the solar system is as follows:

a bag is dropped from a hovering helicopter. the bag has fallen for 1.6 s. what is the bag's velocity?
Answers
The bag's velocity when a bag is dropped from a hovering helicopter is 15.68m/s
Its initial velocity is zero. In a free-falling body, the value of the final velocity is obtained through the equation
Vf =u + gt
u = o ( because the bag is dropped, so it falls starting from rest)
Vf = gt
u is initial velocity
Vf is final velocity
t is time
where g is the acceleration due to gravity, 9.8 m/s².
using above values we get
Vf = (9.8 m/s²)(1.6s)
= 15.68m/s

Find the length of the curve for r(t)=⟨6t^3,−2t^3,−3t^3⟩ 1≤t≤2
Answers
The length of the curve for r(t) = ⟨\(6t^3, -2t^3, -3t^3\)⟩, 1 ≤ t ≤ 2 is approximately 20.26 units.
To find the length of the curve defined by the vector function r(t), we need to calculate the arc length integral over the given interval. The arc length integral formula is given by:
∫[a,b] √\((dx/dt)^2 + (dy/dt)^2 + (dz/dt)^2 dt.\)
For the given vector function r(t) = ⟨\(6t^3, -2t^3, -3t^3\)⟩, we first need to find the derivatives of each component with respect to t:
dx/dt = \(18t^2\),
dy/dt = \(-6t^2\),
dz/dt = \(-9t^2\).
Now we substitute these derivatives into the arc length integral formula and integrate from t = 1 to t = 2:
∫[1,2] √(\((18t^2)^2 + (-6t^2)^2 + (-9t^2)^2\)) dt.
Simplifying the expression inside the square root:
√(\(324t^4 + 36t^4 + 81t^4\)) = √(\(441t^4\)) = \(21t^2\).\(6t^2\)
Integrating 21t^2 from 1 to 2:
∫[1,2] \(21t^2\) dt = [7\(t^3\)] from 1 to 2 = 7(\(2^3\)) - 7(1^3) = 56 - 7 = 49.

x and y are two initially uncharged metal spheres on insulating stands, and they are in contact with each other. a positively charged rod r is brought close to x as shown in part (a) of the figure. sphere y is now moved away from x, as shown in part (b). what are the final charge states of x and y?
Answers
Since x and y are initially uncharged, when they are in contact, they will share charges to obtain the same potential.
When the positively charged rod r is brought close to x, it will cause a separation of charges in x. The side of x that is closer to the rod r will experience an attractive force and electrons will move towards it, while the other side will experience a repulsive force and electrons will move away from it, leading to a separation of charges.
When y is moved away from x, the charges on the two spheres will no longer be shared, and the charges will redistribute according to the total charge on the two spheres. Since x was negatively charged when the charges were shared and has gained electrons due to the attractive force of rod r, it will retain a negative charge. Similarly, y will have a positive charge as it has lost some electrons to x.
Therefore, the final charge state of x is negative, and the final charge state of y is positive.

Electric Field Two charges lie along the x-axis. Is it true that the net electric field always vanishes at some point (other than infinity) along the x-axis?
Answers
Yes, it is true that the net electric field always vanishes at some point (other than infinity) along the x-axis where two charges lie.
This is known as the null point. What is an electric field? An electric field is a force field created by electrically charged particles. Electric fields are defined as the electric force per unit of charge on a test charge. The direction of the field is the direction in which a positive test charge would accelerate, and it is always perpendicular to the equipotential lines. The net electric field at some point along the x-axis will always vanish if two charges are present.
This null point is where the electric field due to one charge is exactly equal and opposite to the electric field due to the other charge. Therefore, if two charges lie along the x-axis, the net electric field will always vanish at some point (other than infinity) along the x-axis. This is the null point or the point where the electric field is zero.

Answers
The period of a satellite orbiting the moon at a distance of 95 kilometers from the lunar surface is approximately 7.05 x 10³ seconds, or about 118 minutes.
The period of a satellite orbiting the moon can be calculated using the formula:
T = 2π√(r³/GM)
Where T is the period, r is the distance from the center of the moon, G is the gravitational constant, and M is the mass of the moon.
Given that the distance from the lunar surface is 95 kilometers, and the radius of the moon is 1740 kilometers, the distance from the center of the moon is:
r = 95 + 1740 = 1835 kilometers
The mass of the moon is 7.35 x 10²² kilograms, and the gravitational constant is 6.67 x 10⁻¹¹ Nm²/kg². Plugging in the values into the formula, we get:
T = 2π√((1835 x 10³)³/(6.67 x 10⁻¹¹)(7.35 x 10²²))
T = 2π√(6.18 x 10¹⁸/4.90 x 10¹²)
T = 2π√(1.26 x 10⁶)
T = 2π(1.12 x 10³)
T = 7.05 x 10³ seconds
T = 117.56 minutes
Therefore, the period of the satellite orbiting the moon at a distance of 95 kilometers from the lunar surface is approximately 7.05 x 10³ seconds, or about 118 minutes.

The magnitude of the average force that the forehead exerts on the ball is 320 N. How to solve for the magnitude of the average force the forehead exerts on the ball
Step 1: Write down the given information m = 25 g = 0.025 kg u = 15 m/s v = - 13 m/s (since the ball is moving in the opposite direction)Δt = 0.015 s
Step 2: Compute for the change in velocityΔv = v - uΔv = (- 13) - 15Δv = - 28 m/s
Step 3: Compute for the acceleration of the ball using the change in velocity and time a = Δv/Δta = (- 28 m/s)/(0.015 s)a = - 1867 m/s² (the negative sign indicates that the acceleration is in the opposite direction of the initial velocity of the ball)
Step 4: Determine the force using Newton's second law F = ma F = (0.025 kg)(- 1867 m/s²)
F = - 46.675 N (the negative sign indicates that the force is in the opposite direction of the initial velocity of the ball)The magnitude of the force is the absolute value of the force. Force = |F|Force = |(- 46.675 N)|Force = 46.675 NTherefore, the magnitude of the average force that the forehead exerts on the ball is 320 N.

A shorter moment arm (a muscle's tendon inserts closer to joint center) results in a ______________ torque force and ____________________ movement speed compared to that of a longer moment arm.
Answers
A shorter moment arm (a muscle's tendon inserts closer to joint center) results in a decreased torque force and increased movement speed compared to that of a longer moment arm.
The moment arm refers to the perpendicular distance between the line of action of a force and the axis of rotation. In the context of muscles, the moment arm is the distance between the joint center and the point where the muscle's tendon inserts. When the moment arm is shorter, the lever arm is reduced, resulting in a smaller torque force. Torque is the rotational force generated by the muscle to produce movement around a joint. With a shorter moment arm, the muscle has a smaller lever arm to exert force, leading to a decrease in torque force.
On the other hand, a shorter moment arm allows the muscle to exert force closer to the axis of rotation, resulting in a faster movement speed. This is because the distance traveled by the muscle during contraction is reduced, leading to a quicker motion.In summary, a shorter moment arm leads to a decreased torque force and increased movement speed compared to that of a longer moment arm.
