a)  The speed of the brick just as it hits the ground is approximately 11.1 m/s.

b) The impulse exerted by the ground on the brick is also 3.33 kg·m/s.

c)   The average force exerted by the ground on the brick is approximately 2562.31 Newtons.

To solve the problem, we can use the principles of kinematics and the laws of motion.

a) To find the speed of the brick just as it hits the ground, we can use the equation:

v = √(2gh)

where v is the velocity, g is the acceleration due to gravity (approximately 9.8 m/s²), and h is the height (8 m in this case).

v = √(2 * 9.8 * 8) ≈ 11.1 m/s

Therefore, the speed of the brick just as it hits the ground is approximately 11.1 m/s.

b) The impulse exerted by the ground on the brick can be calculated using the impulse-momentum principle:

Impulse = Change in momentum

Since the brick comes to rest, its final momentum is zero. The initial momentum can be calculated using the equation:

momentum = mass * velocity

Initial momentum = 0.3 kg * 11.1 m/s = 3.33 kg·m/s

Therefore, the impulse exerted by the ground on the brick is also 3.33 kg·m/s.

c) The average force exerted by the ground on the brick can be calculated using the equation:

Force = Impulse / Time

Force = 3.33 kg·m/s / 0.0013 s ≈ 2562.31 N

Therefore, the average force exerted by the ground on the brick is approximately 2562.31 Newtons.

The sets of vectors that may represent the momenta of two objects after the collision is shown in the image attached.

If a moving object strikes an object at rest at an angle, after collision both the objects will move at right angles to each other. The final momentum vector may or may not be same in magnitude. If the moving object strikes the stationary object head on instead of at an angle, the moving object will become stationary and the stationary object will follow the moving object path. In this scenario both the objects are considered to have same size and mass.

If the object have different size, they bot will move at different velocities. If the moving ball is bigger, they both will move in the same direction. If the stationary ball is bigger, the stationary ball will follow the path of moving ball and the moving ball will go in exactly opposite direction.

Answer:

15.7 ; 78.5

Explanation:

Given that

The mechanic use a screw driver to install 1⁄4-20 UNC bolt

And, the effort force is 5lb

We need to find out the mechanical advantage

And, the resistance force

As we know that

The Mechanical advantage of a screw = Circumference ÷ pitch

where,  

Circumference = pi × d

 pi = 3.142, D = diameter

So,  

Circumference = 3.142 × (1 ÷ 4)

= 0.785 in

Now

Pitch = 1 ÷ TPI

Here TPI (thread per inch) = 20

Pitch = 1 ÷  20 = 0.05

So,

Mechanical advantage = 0.785 ÷ 0.05

= 15.7

Now Resistance force if effort force is 5lb

We know that

Mechanical advantage = Fr ÷ Fe

Here

Fe = effort force, Fr = resistance force

15.7 = Fr ÷ 5

Fr = 15.7 × 5

= 78.5 lbs

Radio, r = 40 m

Para encontrar la fuerza centrípeta;

Fc = mv² / r

Fc = (900 * 13,89²)/40

The weight of the rock on Mars is 5.18 N.

The gravitational potential energy of the rock is indeed  -1.77×10⁷J​

(I) To determine the weight of the rock on Mars, use the formula for weight, which is given by:

Weight = Mass x Acceleration due to gravity

The acceleration due to gravity on Mars can be calculated using the formula:

Acceleration due to gravity = (Gravitational constant x Mass of Mars) / (Radius of Mars)²

Plugging in the given values:

Acceleration due to gravity = (6.67 x 10⁻¹¹ Nm²/kg²) x (6.42 x 10²³ kg) / (3.395 x 10⁶ m)²

= 3.71 m/s²

The weight of the rock can now be calculated as:

Weight = 1.40 kg x 3.71 m/s²

= 5.18 N

(ii) To find the gravitational potential energy of the rock, use the formula:

Gravitational potential energy = -(Gravitational constant x Mass of Mars x Mass of rock) / Distance between the center of Mars and the rock

The distance between the center of Mars and the rock is equal to the radius of Mars, which is given as:

Radius of Mars = 3.395 x 10⁶ m

Plugging in the values:

Gravitational potential energy = -(6.67 x 10⁻¹¹ Nm²/kg²) x (6.42 x 10²³ kg) x (1.40 kg) / (3.395 x 10⁶ m)

= -1.77 x 10⁷ J

7.095 × 10⁵ KHz is the frequency of an electromagnetic wave that has the same wavelength as a 3.5 KHz sound wave in water.

The pace at which current changes direction each second is known as frequency. One hertz (Hz), which is a unit of measurement used internationally, equals one cycle per second. One hertz (Hz) is one cycle every second. A full alternating current or voltage wave is referred to as a cycle.

The number of waves that pass a specific place in a predetermined period of time is known as the wave frequency. A wave passes a fixed point in one hertz (Hz), the SI unit for wave frequency, in one second. A wave with a higher frequency has more energy than a wave with a lower frequency of the same amplitude.

Given that,

frequency = 3.5 KHz

As we know,

V = fλ

As, the electromagnetic wave that has the same wavelength, thus

V/f = constant

Therefore,

V₁/V₂ = f₁/f₂

Explanation:

Answer:

is a force that attracts any two objects with a mass

The net force on an object is zero that is pulled with forces of 80 newtons to the right and 80 newtons to the left.

Net force is equal to sum of all the force acting on a body.

The formula for net force if n force are acting on it:

In this case the two forces are equal but opposite in direction.

Putting the values in the formula

\(F_{net} = 80+(-80)\) (since forces are equal but opposite)

\(F_{net}= 0\)

When a modulus M can be formed entirely from a finite set of elements, the modulus M is said to be finitely generated. M's finite basis does not, however, automatically imply that M is finitely generated. A basis is a set of linearly independent elements, and it might not be enough to produce all of the components of the modulus.

According to the assertion in option b, M must include nonzero items of nonzero order if it has a finite basis. This is untrue, though. The smallest positive number k, such that the element raised to the power of k equals the identity element, is referred to as the order of an element.
