A 235 kg object and a 1.37×1012 kg are located 2.59×104 m away from each other. What is the force due to gravity between the two

Alexus [3.1K]

Answer:

F = 3.2 x 10⁻⁵ N

Explanation:

The gravitational force of attraction between the two objects is given by Newton's Gravitational law through the following formula:

$F = \frac{Gm_{1}m_{2}}{r^{2}}$

where,

F = gravitational force = ?

G = Gravitational Constant = 6.67 x 10⁻¹¹ Nm²/kg²

m₁ = mass of object 1 = 235 kg

m₂ = mass of object 2 = 1.37 x 10¹² kg

r = distance between objects = 2.59 x 10⁴ m

Therefore,

$F = \frac{(6.67\ x\ 10^{-11}\ Nm^{2}/kg^{2})(235\ kg)(1.37\ x\ 10^{12}\ kg)}{(2.59\ x\ 10^{4}\ m)^{2}}$

F = 3.2 x 10⁻⁵ N

A rocket starts from rest and moves upward from the surface of the earth. For the first 10s of its motion, the vertical accelera

Naily [24]

Since the rocket’s acceleration is 3.00 m/s^3 * t, its acceleration is increasing at the rate of 3 m/s^3 each second. The equation for its velocity at a specific time is the integral of the acceleration equation.

vf = vi + 1.5 * t^2, vi = 0 
vf = 1.5 * 10^2 = 150 m/s 
This is the rocket’s velocity at 10 seconds. The equation for its height at specific time is the integral velocity equation

yf = yi + 0.5 * t^3, yi = 0 
yf = 0.5 * 10^3 = 500 meters 
This is the rocket’s height at 10 seconds. 

Part B 
What is the speed of the rocket when it is 345 m above the surface of the earth? 
Express your answer with the appropriate units. 

Use the equation above to determine the time. 

345 = 0.5 * t^3 
t^3 = 690 
t = 690^⅓ 
This is approximately 8.837 seconds. Use the following equation to determine the velocity at this time. 

v = 1.5 * t^2 = 1.5 * (690^⅓)^2 
This is approximately 117 m/s. 

The graph of height versus time is the graph of a cubic function. The graph of velocity is a parabola. The graph of acceleration versus time is line. The slope of the line is the coefficient of t. This is a very different type of problem. For the acceleration to increase, the force must be increasing. To see what this feels like slowly push the accelerator pedal of a car to the floor. Just don’t do this so long that your car is speeding!!

Which activities are you always doing when you have a warm-up activity?

Sati [7]

A jog because it helps to get the muscles moving and your heart pumping blood around your body.

I hope this helps.

Why do the heights of the tides change over the course of a month?

Y_Kistochka [10]

Answer:

The heights of the tides change over the course of a month due to -

the position of Sun , Moon and Earth .

Explanation:

Tides are formed due to the gravitational attraction of the sun and the moon on the surface of the Earth .

Since , the Moon is closer to Earth as compared to the Sun , Hence , Moon has greater attraction on Earth than Sun .

Moon plays an important role for producing the Tides .

In every 27.3 days , the Earth and the Moon revolves around the common point .

Therefore , in every 27.3 days , a new tidal cycle forms .

Two types of tides are possible , high tide and low tides .

In a day , two high tide and two low tide occurs ,

And because of the angle of Moon with respect to Earth , the two high tides do not have the same height . same for the case of two low tide .

The height of tides differ in the height on a daily basis .
