According to Newton's Law of Universal Gravitation, which of the following would cause the attractive force between a planet and

Applying the formula of force equals mass times acceleration, and considering acceleration approximated as g at 10 m/s², the brick possessing the greater mass will hit the ground first due to its superior force that counteracts resistive forces like air resistance.

Answer:160j

Explanation:

PE=mgh

where m=8kg

g=10N/kg

h=2m

Thus, PE=8*10*2

This results in PE=160j

Answer:

Velocity = v = 2.24 m/s

Acceleration = a = 0.20 m/s²

Explanation:

Refer to the attachment below.

Given

z=(−8 cosθ) and θ = 0.3t

z = -8Cos (0.3t)

V = dz/dt

a = v²/R.

Please see full solution below.

Starting speed of the coin (u)= 0 (Since it starts from rest)

Gravitational acceleration (a) = g = 9.81 m/s²

Duration of the fall (t) = 1.5 s

According to the motion equation we can state:

Substituting the known values into the equation yields:

v = 0 + 9.81 × 1.5

v = 14.715 m/s

The speed of the coin upon reaching the ground/Final speed of the coin = 14.715 m/s

Answer:

option (c)

Explanation:

The current induced in the coil flows clockwise when viewed from above, hence the induced magnetic field points downwards. According to Lenz's law, the applied magnetic field across the coil is directed downwards and diminishes in strength. As a result, the current induced will circulate in a manner that seeks to enhance the applied magnetic field.
