To find the centripetal acceleration, we have to apply the formula for centripetal acceleration:

where v = velocity of the vehicle

r = radius of the circular path

Therefore, the centripetal acceleration is:

That is the answer.

The correct answer is centrifuge.

Your complete blood is drawn out during an apheresis procedure, which is used to donate platelets. Your blood is spun in a centrifuge to separate your plasma, platelets, and red blood cells. As the blood is divided, the heavier reds cells drop to the bottom and are given back to you.

Between the liquid plasma and the platelets that are tracked into a small pouch that is wrapped around the centrifuge cylinder as the liquid plasma rises. When you donate blood, your spleen releases stockpiled platelets into your bloodstream in an effort to stop the bleeding.

As a result, more platelets and plasma are collected, enabling you to donate one, two, or even three doses of platelets in a single visit. Your healthy bone marrow quickly starts producing additional platelets from stem cells to replace those that have been given while this is happening.

Since only one donor is used for the donation, platelet donors are able to provide patients with a greater amount and higher-quality platelets to aid in their fight for survival.

Answer:

mass = 444.44 kg

Explanation:

To calculate the mass of the truck, we can use the formula for momentum:

Momentum (p) = mass (m) × velocity (v)

Given:

Momentum (p) = 40,000 kg·m/s

Velocity (v) = 90 m/s

We can rearrange the formula to solve for mass (m):

m = p / v

Substituting the given values:

m = 40,000 kg·m/s / 90 m/s

m ≈ 444.44 kg

Therefore, the mass of the truck is approximately 444.44 kg.

Answer:

A)    Net force in the horizontal direction is 19.641 N

B)    Net force in the vertical direction is 20 N

Explanation:

The normal force (20 N) and the weight force (20 N) cancel out.

Next lets find the horizontal and vertical components on the right side of the diagram.

We are given the angle and the hypotenuse.

First lets find the opposite side (vertical component).

\(sin(x)\frac{O}{H}\)

\(O=Hsin(x)\)

\(O=40sin(30)\)

\(O=20\)

Now lets find the adjacent side (horizontal component).

\(cos(x)=\frac{A}{H}\)

\(A=Hcos(x)\)

\(A=40cos(30)\)

\(A=34.641\)

Now we can ignore the 40 N force.

We are left with 1 force in the vertical direction.

So the net force in the vertical direction is 20 N

We are left with 2 forces in the horizontal direction.

We have 1 force of 15 Newtons moving in the left direction.

We also another force of 34.641 Newtons moving to the right.

So the net force in the horizontal direction is 19.641 N.

Ok, so at point 20 on the x axis you put 12 on the y-axis, then draw a line from 0, 0 to that point, this demonstrates the acceleration to 12 m/s.

Next, calculate the time he cycled for if he suckled the distance of 4800m :

4800/12 = 400 s

Put a dot at 400, 12. The time changed but the speed remained constant, line is horizontal.

For the last one, he had to decelerate at an equal speed. Since there is 100 s left of the journey at that stage, You need to draw a straight line from the previous point to 500, 0. So at time 500 he was not accelerating at all, he came to rest.

The work required to pull the hanging part of the chain back onto the table is equal to -m * g * (1/4) * L, considering the potential energy of the hanging portion.

The potential energy of an object is given by the formula:

Potential Energy = Mass * Gravitational Acceleration * Height

In this case, the height of the hanging portion of the chain is one-fourth of its total length, which is (1/4) * L.

Therefore, the potential energy of the hanging portion is:

Potential Energy = (m * g * (1/4) * L)

To bring the hanging portion back onto the table, the work done is equal to the negative change in potential energy.

Work = -Potential Energy

Work = -m * g * (1/4) * L

Answer:

it's 7 I know it was easy because 99.4÷14.2

Sure! Here are the steps for calculating the velocity and distance traveled by the car after 50 seconds :

Step 1: Calculate the velocity using the equation:

\(v = u + at\)

where:

- \(v\) is the final velocity

- \(u\) is the initial velocity (0 m/s, as the car starts from rest)

- \(a\) is the acceleration (3 m/s²)

- \(t\) is the time (50 seconds)

Substituting the values into the equation:

\(v = 0 + (3 \, \text{m/s²}) \times (50 \, \text{s})\)

Step 2: Calculate the distance traveled using the equation:

\(s = ut + \frac{1}{2}at^2\)

where:

- \(s\) is the distance traveled

- \(u\) is the initial velocity (0 m/s)

- \(a\) is the acceleration (3 m/s²)

- \(t\) is the time (50 seconds)

Substituting the values into the equation:

\(s = 0 \times (50 \, \text{s}) + \frac{1}{2} \times (3 \, \text{m/s²}) \times (50 \, \text{s})^2\)

Now, let's simplify these equations:

\(v = 3 \times 50\)

\(s = \frac{1}{2} \times 3 \times 50^2\)

Calculating the results:

\(v = 150\) m/s

\(s = 3750\) meters

Therefore, after 50 seconds, the car will have a velocity of 150 m/s and would have traveled a distance of 3750 meters.

Answer: 25.1m

Explanation:

The expression of the initial potential energy when the ball is tossed upwards is given as followed

\(PE_{i}\)=mg\(PE_{i}= mgh_{0}\)

Here, m is the mass of the ball, g is the acceleration due to gravity and is the initial height.

The initial kinetic energy of the ball is:

\(KE_{i} =\frac{1}{2}mv^2\)

The final potential energy of the ball at the maximum height is given as:

\(PE_{f}=mgh_{max}\)

The final kinetic energy is at the maximum height is:

\(KE_{f} =0\)

Now you will use the conservation of energy princi\(h_{0}\)ple and substitute the equations into the expression below:

\(KE_{i}+PE_i=KE_f+PE_f\)

\(\frac{1}{2}mv^2+mgh_0=0+mgh_{max}\)

\(h_{max}=h_0+\frac{v^2}{2g}\)

Now substitute 9.81 m/\(s^{2}\) for g, 10m/s for v, and 20.0 m for \(h_{0}\) in the equation above.

h\(_{max}}=(20.0m)+\frac{(10m/s)^2}{2(9.81m/s^2}\)

which is equal to 25.1m

Answer:

λ = 610.6 nm

Explanation:

We are given;

Separation distance; d = 0.195 mm = 0.195 × 10^(-3) m

Interference pattern distance; D = 4.95 m

Width of the two adjacent bright interference; β = 1.55 cm = 1.55 × 10^(-2) m

Formula for the Fringe width is;

β = Dλ/d

Where;

λ is laser's wavelength

Thus;

λ = (d × β)/(D)

λ = (0.195 × 10^(-3) × 1.55 × 10^(-2))/4.95

λ = 610.6 × 10^(-9) m

λ = 610.6 nm

Using Conservation of energy property

The equilibrium temperature reached is T = 33.8 C

According to the rule of conservation of energy, the overall energy of an isolated system stays constant over time. According to this law, which  first suggested and tested, energy can only be changed or moved from one form to another and cannot be generated or destroyed. For instance, when a stick of dynamite explodes, chemical energy is transformed into kinetic energy. One can calculate the precise reduction in chemical energy in the dynamite's combustion by adding up all the energies released during the explosion, including the kinetic and potential energy of the fragments, heat, and sound.

where

T = equilibrium temperature of the system

Since Qs = Qi,

\(0.0075(22.6\ X\ 10^5) + 0.0075(4186)(100 - T) = 0.040(3.34\ X\ 10^5) + 0.040(4186)(T - 0)\)

\(0.1695\ X\ 10^5 + 31.395(100 - T) = 0.1336\ X\ 10^5 + 167.44(T)\)

Simplifying,

\(0.1695\ X\ 10^5 + 3139.5 - 31.395T = 0.1336\ X\ 10^5 + 167.44T\)

Combining terms,

\(167.44T + 31.395T = 0.1695\ X\ 10^5 - 0.1336\ X\ 10^5 + 0.031395\ X\ 10^5\)

Inverse relationships are common in nature. In electrostatics, the electrical force between two charged objects is inversely related to the distance of separation between the two objects. Increasing the separation distance between objects decreases the force of attraction or repulsion between the objects.

Explanation:

Two ways to decrease the electric force between two charged objects:

As a result of their electric charge, particles or objects are attracted to or repelled by the Coulomb force, also known as electrostatic force or Coulomb interaction. Charles-Augustin de Coulomb, a French scientist who published the findings of an experimental inquiry into the proper quantitative description of this force in 1785, gave the electric force its name. The electric force is one of the fundamental physical forces.
