What kind of force pulls a system back to equilibrium

Physics
1 answer:
Contact [7]4 years ago
3 0

Answer:

Restoring Force

Explanation:

The distance from one crest to the next is a wave's wavelength. This kind of force pulls a system back to equilibrium: restoring force. Sound waves are an example of this kind of wave: longitudinal wave. The amplitude of two waves will cancel when destructive interference occurs.

It’s your birthday, and to celebrate you’re going to make your first bungee jump. You stand on a bridge 100 m above a raging riv
amm1812

Answer:

X'=50.4\,m

Explanation:

Given that:

Height of jump, h=100\,m

length of elastic cord, l=30\,m

spring constant of the cord, k=40\,N.m^{-1}

mass of the body that jumps, m=80\,kg

Force on the bungee elastic cord:

F=m.g

F=80\times 9.8

Now this force F will be responsible for the elongation in the elastic cord, so:

F=k.x ............................(1)

where :

k = spring constant

x = extension in the elastic cord

using eq. (1)

80\times 9.8=40\times x

x=19.6\,m

So the cord stretches 19.6 meters more beyond its original length of 30 meters.

Hence, the remaining distance from the river surface at the bottom is:

X'=100-(30+19.6)

X'=50.4\,m

MrRa [10]

Explanation :

Takumi wears sunscreen and a hat each time he works in the yard. This is to protect himself with the strong radiation coming from the sun. UV rays that are coming from the sun are the main cause of skin cancer.

Stochastic effects are the effects that are caused by chance. Cancer is one of the main stochastic effects.

So, the correct option is (b) "the severity of stochastic effects, such as cancer".

GrogVix [38]

Answer:

P = I V       power produced by source at voltage V thru resistance R

I = V / R      current thru resistance R

P = V^2 / R

Power produced will decrease as the output resistance R increases

Check: if R increases to ∞ the power produced will go to zero
