Note that the simulation allows you to also display the force of the smaller moon
Lelu [443]

the force that the planet exerts on the moon is equal to the force that the moon exerts on the planet

Explanation:

In this problem we are analzying the gravitational force acting between a planet and its moon.

The magnitude of the gravitational attraction between two objects is given by

F=G\frac{m_1 m_2}{r^2}

where :

G=6.67\cdot 10^{-11} m^3 kg^{-1}s^{-2} is the gravitational constant

m1, m2 are the masses of the two objects

r is the separation between them

In this problem, we are considering a planet and its moon. According to Newton's third law of motion,

"When an object A exerts a force (action force) on an object B, then object B exerts an equal and opposite force (reaction force) on object A"

If we apply this law to this situation, this means that the force that the planet exerts on the moon is equal to the force that the moon exerts on the planet.

At t=0, a particle leaves the origin with a velocity of 9.0 m/s in the positive y direction and moves in the xy plane with a con
fiasKO [112]

Answer:

e.26m/s

Explanation:

Vf=Vi+at      (1)

Vf=9j+(2i-4j)t

X= X₀+at

now, in the i direction

15=O+2t or t=7.5 when x position is 15

Lets put that into the (1) equation, solve for Vf.

 Vf=9j+(2i-4j)7.5

Vf= 15i - 21j

Speed= \sqrt{xcomponent^2 + ycomponent^2}

Vf= 25.8 m/s

How is Behaviorism and Psychoanalysis theories are different?
ivanzaharov [21]

Answer:

Behaviorists give prominence to the external behavior of individuals and believe that behavior is a response to external stimuli. On the other hand, psychoanalysis emphasizes the centrality of the human mind. They believe that the unconscious has the potential to motivate behavior.

Imagine that a space probe could be fired as a projectile from the Earth's surface with an initial speed of 5.52 104 m/s relativ
Thepotemich [5.8K]

Answer:

v_f = 5.4 \times 10^4 m/s

Explanation:

As per energy conservation we can say

initial total energy of the object at the surface of earth = final total energy of the object at highest height

now we have

U_i = -\frac{GMm}{R} + \frac{1}{2}mv^2

here we know that

M = mass of earth

m = mass of object

R = radius of earth

now when object reached far away from the earth then it will only have kinetic energy

U_f = \frac{1}{2}mv_f^2

now by energy conservation

-\frac{GMm}{R} + \frac{1}{2}mv^2 = = \frac{1}{2}mv_f^2

-\frac{GM}{R} + \frac{1}{2}v^2 = \frac{1}{2}v_f^2

-\frac{(6.67 \times 10^{-11})(5.98\times 10^{24})}{6.37\times 10^6} + \frac{1}{2}(5.52 \times 10^4)^2 = \frac{1}{2}v_f^2

-6.26 \times 10^7 + 1.52 \times 10^8 = \frac{1}{2}v^2

v_f = 5.4 \times 10^4 m/s
