Answer: yes wave are created by vibration because if there anit any vibration then the water cant move
Explanation:
The mass that must be added is 0.628 kg
Explanation:
The period of a mass-spring system is given by

where
m is the mass
k is the spring constant
For the initial mass-spring system in the problem, we have
m = 0.500 kg
T = 1.36 s
Solving for k, we find the spring constant:

In the second part, we want the period of the same system to be
T = 2.04 s
Therefore, the mass on the spring in this case must be

Therefore, the mass that must be added is

A or E I think cous I use to do this in yr 7
The answer is A. the moving charge induces a magnet field
.
The second Newton's law of motion states that the rate of change in momentum of a moving body is proportional to the resultant force.
Therefore, to understand this law one must understand the concept of momentum and that a body in motion experiences force.
As far as momentum is concerned it is important to note that as a body moves the momentum changes with change in time and also that a body at rest has 0 momentum because its speed/velocity is zero.
It is this change in momentum with time that is proportional to the resultant force experienced by the body.
