Answer:
Explanation:
Given
Amplitude of oscillation is A
spring constant k
suppose m is the mass of block so its natural frequency of oscillation is given by
When three identical springs is connected in series
Natural Frequency becomes
Thus maximum speed with Amplitude A is
so by a factor of maximum velocity is changed
Insulators do not allow electrons to move easily through them.
Answer:
5 km/hr because he thinks it moves in the same speed of his...
