Answer:
Kinetic energy is the energy an object has because of its motion. If we want to accelerate an object, then we must apply a force. Applying a force requires us to do work. After work has been done, energy has been transferred to the object, and the object will be moving with a new constant speed.
Answer:
F= 15.6 N, a= 33.2 m/s^2
Explanation:
mass= m = 0.47 kg
spring constant= k = 130N/m
spring compression = x = 0.12 m
a).
force on the mass= F = k*x
F = 130 * 0.12 N
F= 15.6 N
b).
Acceleration of mass= a=?
F= ma
a=F / m
a= 15.6/ 0.47 m/s^2
a= 33.2 m/s^2
Answer:
B) Faster than before
Explanation:
By the time you begin to wiggle the string more rapidly you are indirectly increasing the number of cycles of the generated wave per second. This means that you are increasing the frequency of the generated wave.
Recall that the frequency of a travelling wave depends on the source of the wave. You generating the wave are the source of the wave.
The general relationship between velocity, frequency and wavelength is given by equation (1);

This shows a linear and direct relationship between velocity v and frequency f. That is to say that when frequency increases, velocity will also increase and vice versa.
As long as other factors such as the tension in the string remains constant, wiggling at a more rapid rate increases the frequency and which also increases the velocity, causing the wave to travel faster than before.
Absolutely none. Fish take food into their mouths and taste it. If they
like it, they swallow, if not they will spit it out. The color of the
flakes has no bearing on what the fish takes in and tastes in my
experience.
I hope this helps : )
