Answer:

(4) weight

Explanation:

The centripetal force acting on the space shuttle in orbit is given by:

$F=m\frac{v^2}{r}$

where

m is the mass of the shuttle

v is the tangential speed of the shuttle

r is the radius of its circular orbit

When the shuttle orbits the Earth, the centripetal force that keeps the shuttle in circular motion is given by the gravitational attraction between the shuttle and the Earth, which corresponds to the weight of the shuttle, and it is given by:

$F=G\frac{Mm}{r^2}$

where

G is the gravitational constant

M is the Earth's mass

And this force, therefore, corresponds to the centripetal force.

Option (4) is correct. The centripetal force acting on the space shuttle is equal to the weight of the space shuttle.

Explanation:

The centripetal force is the force that is experienced by a body when it is moving in a circular path. As the body moves, the force experienced by the body towards its center and it is called as the centripetal force.

When the space shuttle present in the space is moving around the Earth in a particular orbit, there is a force acting on the space shuttle due to its speed in the circular path. This force is the centripetal force.

To keep the space shuttle to move in its definite path, the weight of the space shuttle acts in the direction opposite to the centripetal force and keeps the shuttle from moving out of the path.

Thus, Option (4) is correct. The centripetal force acting on the space shuttle is equal to the weight of the space shuttle.

Two pulleys, one with radius 2 inches and one with radius 9 inches, are connected by a belt. If the 2-inch pulley is caused to

mart [117]

Answer:

the revolutions per minute for the 9 inch pulley is 10/9.

Explanation:

Step 1:

The linear speed of the belt is

linear speed = circumference × revolutions per minute, that is

v = 2π r × ω

where

r is the radius of the pulley
ω is the revolutions per minute

Therefore, the linear speed of the 2 inch pulley is:

v₂ = (2π × 2 in) × (5 rev/min)

v₂ = 4π × (5 rev/min)

Step 2:

Compute the linear speed of the belt for the 9 inch pulley:

v₈ = (2π × 9 in) × (x rev/min)

v₈ = 18π × (x rev/min)

Step 3:

Since the linear speed is the same for both pulleys, therefore

v₂ = v₈

4π × (5 rev/min) = 18π × ω₈

ω₈ = (4π × (5 rev/min)) / 18π

ω₈ = 10/9 rev/min

Therefore, the revolutions per minute for the 8 inch pulley is 10/9.

Cylinder A has a mass of 2kg and cylinder B has a mass of 10kg. Determinethe velocity of A after it has displaced 2m from its or

Marta_Voda [28]

The velocity of A is 5.16m/s²

Explanation:

Given-

mass of cylinder A, mₐ = 2kg

mass of cylinder B, mb = 10kg

Distance, s = 2m

Velocity of A, v = ?

Let acceleration due to gravity, g = 10m/s²

We know,

$a = \frac{mb * g - ma * g}{ma + mb} \\\\a = \frac{10 * 10 - 2 * 10}{ 2 + 10} \\\\a = \frac{80}{12} \\\\a = 6.67m/s^2$

We know,

$v = \sqrt{2as}$

$v = \sqrt{2 X 6.67 X 2} \\\\v = \sqrt{26.68} \\\\v = 5.16m/s^2$

Therefore, the velocity of A is 5.16m/s²

A 4.00 kg block is pushed along the ceiling with a constant applied force of 85.0 N that acts at an angle of 55.0 degrees with t

steposvetlana [31]

Answer:

0.35

Explanation:

According to Newton's second law;

\sum Fx = ma

Fm - Ff =ma

Fm is the moving force = Wsin theta

Fm = 4(9.8)sin55

Fm = 32.1N

Ff is the frictional force = nmgcos theta

Ff = n(4)(9.8)cos55

Ff = 22.48n

Acceleration a = 6.0m/s²

Substitute the given values into the formula and get the coefficient of friction

32.11-23.48n = 4(6)

32.11-24= 23.48n

8.11 = 23.48

n = 8.11/23.48

n = 0.35

Hence the coefficient of friction is 0.35

____ is the thermal energy transfer that occurs from the motion of fluid in a liquid or gas.

Marysya12 [62]

The answer is C. Convection.

Radiation is the transfer of energy through electromagnetic waves. Conduction, on the other hand, is energy transfer through solid material. Condensation occurs when warm gas makes contact with a cold surface or environment, which causes a change in state from gas to liquid. These definitions rule out choices A, B, and D.

Convection is movement of particles in fluid or gas. As liquid/gas heats up, it becomes less dense and rises, moving away from the heat source. When it rises, it eventually cools down and sinks again. It is warmed up again and the cycle continues. This is why there is a circular motion when convection occurs.
