Risk of return on investment is higher than other forms of energy generation.
Answer:
Explanation:
We need only to apply the definition of acceleration, which is:
In our case the final velocity is , the initial velocity is since it departs from rest, the final time is and the initial time we are considering is
So for our values we have:
Answer:
Explanation:
Given
mas of car=870 kg
coffee mug mass=0.47 kg
coefficient of static friction between mug and roof
Coefficient of kinetic Friction
maximum car acceleration is
here coefficient of static friction comes in to action because mug is placed over car . If mug is moving relative to car then \mu _k is come into effect
Answer:
If the frequency of the motion of a simple harmonic oscillator is doubled , then maximum speed of the oscillator changes by the factor 2
Explanation:
We know that in a simple harmonic oscillator the maximum speed is given by
=
Here A is amplitude which is constant , so from above equation we see that maximum speed is directly proportional to of the oscillation .
Since
= 2
Where is the maximum speed when frequency is doubled .
