Answer:
8.6 m/s
Explanation:
We can find the final velocity of the dog by using the following SUVAT equation:

where
u is the initial velocity
a is the acceleration
d is the distance covered
For the dog in the problem, we have
u = 1.5 m/s

And the distance covered is
d = 3.0 m
Therefore, we can re-arrange the equation to find the final velocity, v:

Answer:
Explanation:
General Equation of SHM is given by


where x=position of particle
A=maximum Amplitude
angular frequency
t=time
At any time Total Energy is the sum of kinetic Energy and Elastic potential Energy i.e. 
where k=spring constant
Potential Energy is given by 
also it is given that Potential Energy(U) is equal to Kinetic Energy(K)
Total Energy
Total


at 
velocity is
V(voltage) = I(current)R(resistance)
substitute in the values
V = 15 * 0.10
V = 1.5 volts
In a nuclear power plant, energy is released from the nuclei of atoms. The correct option among all the options given in the question is the first option. Huge amount of thermal energy is released by the breaking of the uranium atoms. This energy is used for turning a turbine that produces electricity. It is a very clean method of producing electricity.
