Answer:
a.
b.
Explanation:
The computation is shown below:
data provided in the question
The initial angular velocity = 0 rev/s,
f = Final angular velocity = = 382000 rpm i.e = = 6,366.67
And time = t = 3.0s
Based on the above information
a. For angular acceleration of drill
b. For the number of revolutions
We simply applied the above formulas for determining each parts
Explanation:
this is the answer for your question if you have any doubt you can join
Answer:
The distance is 2 cm
Solution:
According to the question:
Magnetic field of Earth, B_{E} =
Current, I = 5.0 A
We know that the formula of magnetic field is given by:
where
d = distance from current carrying wire
Now,
d = 0.02 m 2 cm
The answer would 0. The reasoning of this is because freezing point in celsius is always 0 degrees but in fahrenheit the freezing point is 32 degrees.
Answer:
because the gravitational pull is maximum at the poles and decreases as it comes down toward the equator.
