Uranus is tilted so far that it essentially orbits the sun on its side, with the axis of its spin nearly pointing at the star
Answer:
Angular acceleration, is 
Explanation:
Given that,
Initial speed of the drill, 
After 4.28 s of constant angular acceleration it turns at a rate of 28940 rev/min, final angular speed, 
We need to find the drill’s angular acceleration. It is given by the rate of change of angular velocity.
So, the drill's angular acceleration is .
Answer:
DU = 375 Joules
Explanation:
Given the following data;
Quantity of heat = 500 Joules
Work done = 125 Joules
To find the change in internal energy;
Mathematically, the change in internal energy of a system is given by the formula;
DU = Q - W
Where;
- DU is the change in internal energy.
- Q is the quantity of energy.
- W is the work done.
Substituting into the formula, we have;
DU = 500 - 125
<em>DU = 375 Joules</em>
Answer:
If the strings have same thickness but different lengths then these parameters wave frequency, speed, wavelength will be different in the two strings. so the option d) None of the above is correct.
