Potential and kinetic energy
3x10^8 m/s, or the ‘speed of light’ - this applies to the entire spectrum
The time between two new Moon phases or two full Moon phases is 29.5 days. ... The difference of 29.5 and 27.3 is that while the Moon is orbiting the Earth, the Earth is moving along in its orbit so it takes longer for the Moon to reach the same position relative to the Sun.
Answer
given,
mass of block = 2.7 kg
speed of block = 1.1 m/s
a) spring compressed to distance of 6 cm or 0.06 m
using conservation of energy
kinetic energy is converted into spring energy



k= 907.5 N/m
b) again using conservation of energy
kinetic energy is converted into spring energy




v= 0.275 m/s
Answer:
Well that depends on the force that is being applied onto the table and how much is being forced back
Explanation:
When learning about net force there should be some numbers with a N next to them showing you the direction of the newtons. In order to solve this problem and figure out the net force you have to subtract the newtons ( larger number first no negative newtons) then the largest newton after the subtraction the direction is the same direction as the biggest number
Example: 20N⬆️
30N⬇️
Subtract 30-20=10N⬇️
