Watching television, with theremote control in your hand, which of the following exerts the greatest gravitational force on you? A) The couch you are sitting on

B) The TV actors tne room

C) The moon

D) The remote control in your hand

Answers

A. The couch you are sitting on

Final answer:

The gravitational force an object exerts is influenced by its mass and distance. From the options, the moon exerts the most gravitational force because of its significant mass, despite being far away.

Explanation:

The factor that determines the gravitational force exerted by an object is both its mass and the distance from it. The equation for gravitational force is F = G * (m1 * m2) / r^2, where 'G' is the gravitational constant, 'm1' and 'm2' are the masses of the two objects, and 'r' is the distance between their centers.

In the options given: the remote control, the couch, TV actors, and the moon, despite the latter being far off, still, the moon exerts the strongest gravitational force on you. The magnitude of gravitational force exerted by the moon is larger due to its massive size compared to the rest, even though it's far away. The effect is noticeable in the ebb and flow of ocean tides caused by the moon's gravity.

A model rocket rises from rest with constant acceleration of 106m/s2.what is the rocket speed at a height of 3.2m

Answers

At a height of 3.2 meters, the final speed of the model rocket is 26.05 m/s.

Given the following data:

  • Initial speed = 0 m/s (since the model rocket accelerated from rest).
  • Acceleration = 106 m/s^2
  • Distance (height) = 3.2 meters.

To find the final speed of the model rocket, we would use the third equation of motion;

V^2 = U^2 + 2aS

Where:

  • V is the final speed.
  • U is the initial speed.
  • a is the acceleration.
  • S is the displacement or distance covered.

Substituting the given parameters into the formula, we have;

V^2 = 0^2 + 2(106)(3.2)\n\nV^2 = 0 + 678.4\n\nV = √(678.4)

Final velocity, V = 26.05 m/s

We can solve the problem by using the following equation:

v_f ^2 -v_i^2 =2aS

where

vf is the final speed of the rocket

vi=0 is the initial speed of the rocket (it starts from rest)

a=106 m/s^2 is the rocket's acceleration

S=3.2 m is the distance covered by the rocket

Re-arranging the equation, we find the velocity of the rocket after 3.2 m:

v_f = √(2aS)=√(2(106 m/s^2)(3.2 m))=26.0 m/s
