The force of Earth's gravity pulls down on a stone after someone tosses it off a cliff. What is the "equal and opposite force" d
Lapatulllka [165]

The equal and opposite force is the force of the stone's gravity pulling up on thy Earth.

<u>Explanation</u>:

                                      F_{AB} = - F_{BA}

  • When someone tosses a stone off a cliff, the force of gravity of Earth pulls down and the force of the stone's gravity pulls up on the Earth due to the equal and opposite reaction exerted between the Earth and the stone.
  • In Newton's third law, two important features are present. One is the force exerted on two bodies will have the same magnitude but opposite direction. The other feature is force is acting on two different objects.
  • This exerted force is equal in magnitude but opposite in direction whereas the gravity exerts a downward force on a stone and upward force on an Earth which is opposite in direction.

Owen throws a baseball straight upward. We can ignore air resistance.
dusya [7]

Answer:

The acceleration of the ball is constant and equal to -9.81 m/s² (acting downwards)

The velocity of the ball reduces at a constant rate with time on its way up

Explanation:

The motion of the ball upwards is described by the following equation;

v = u - g × t

v² = u² - 2 × g × s

Where;

v = The final velocity of the ball

u = The initial velocity of the ball

g = The acceleration due to gravity = Constant

s = The height of the bass after a given time, t

t = The time in which the ball is rising

Therefore, the acceleration of the ball = The acceleration due to gravity  (Constant) = -9.81 m/s²↓

From v = u - g × t = u - 9.81 × t , the velocity of the ball reduces at a constant rate with time on its way up.

A soap bubble, when illuminated with light of frequency 5.27 Hz × 1014 Hz, appears to be especially reflective. If it is surroun
denis23 [38]

Answer:

1.07004\times 10^{-7}\ m

Explanation:

n_s = Refractive index of bubble = 1.33

f = Frequency of light = 5.27\times 10^{14}\ Hz

c = Speed of light = 3\times 10^8\ m/s

The wavelength of light is given by

\lambda=\dfrac{2n_st}{m-\dfrac{1}{2}}

Wavelength is also given by

\lambda=\dfrac{c}{f}

m = 1 for minimum thickness

\dfrac{c}{f}=\dfrac{2n_st}{m-\dfrac{1}{2}}\\\Rightarrow t=\dfrac{m-\dfrac{1}{2}c}{2n_sf}\\\Rightarrow t=\dfrac{(1-\dfrac{1}{2})\times 3\times 10^8}{2\times 1.33\times 5.27\times 10^{14}}\\\Rightarrow t=1.07004\times 10^{-7}\ m

The minimum thickness is 1.07004\times 10^{-7}\ m
