Explanation:
We have,
Spring constant of the spring, k = 165 N/m
Mass, m = 2 kg
It is required to find the period of the mass-spring system. For the spring mass system, the period is given by :
The frequency of vibration is reciprocal of its time period. So,
So, the period of the mass-spring system is 0.69 s and frequency is 1.44 Hz.
Answer:6.71 m/s
Explanation:
Given
Apple fall from a height of 
We need to find the impact speed of apple which can be given by using
where v=final velocity
u=initial velocity
h=Displacement
Assuming initial velocity to be zero
substituting the value we get
<span>as i recall, gravity is relative to the square of the distance.
so if the distance is tripled, then the gravitational attraction would be reduced by 3^2 or 1/9.
so F1 = F0/9
if the satellite is 2R from the center, and is moved to 4R (doubled would be 3R, tripled is 4R) then the distance is twice, and gravity would be 2^2 or 1/4.

Answer:
These energy exchanges are not changes in kinetic energy. They are changes in bonding energy between the molecules. If heat is coming into a substance during a phase change, then this energy is used to break the bonds between the molecules of the substance.
There is an equation for this, and it will help us answer the question:
F = G × m₁*m₂ ÷ r²
The question already tells us the force of gravity between two objects depends on the objects' mass. Now we have to find a second factor.
Their shapes are not a secondary factor to this question.
What they are made of is not a factor to the gravitational force between the two.
Their weights have nothing to do with this either.
However, the distance does. According to the equation
F = G × m₁*m₂ ÷ r²
r² is the radius, or in other words, the distance between the two masses from their center of gravity. Therefore the distance and masses of two objects are what affect the gravitational pull between the two.
Have a nice day!
