Answer: the mutual inductance is - 0.0978H
Explanation:
Detailed explanation and calculation is shown in the image below
Answer:
9.8 m/s²
Explanation:
Earths gravity acts upon objects with a steady force of 9.8 m/s². The force of gravity is attractive in nature. It acts between two objects. It always acts towards the ground. The force off gravity is given by :
F = W = mg
m is mass of the object and g is the acceleration due to gravity. The value of g is 9.8 m/s². Hence, Earth's gravity acts upon objects with a steady force of 9.8 m/s².
Answer:
(1)
(2)
(3)
And we know from the info given that:

And replacing into equation (3) we got:

So then we can conclude that the scale will read 443.878 N for Florence
Explanation:
For this case we have an accelerator moving downward with an acceleration a.
On this case the person fell like the weight is less than the normal since the required force on the elevator floor is lower than the normal force, for this reason the body accelerate downward.
We can use the formula of apparent weight given by:
(1)
Where AW represent the apparent weigth of the person in the elevator
We also know that the weigth is defined as:

If we solve for m we got:
(2)
If we replace equation (2) into equation (1) we got:
(3)
And we know from the info given that:

And replacing into equation (3) we got:

So then we can conclude that the scale will read 443.878 N for Florence
Are you sure it is not A? That's what I believe the answer is.
The story sure is exciting. But when you're ready to work on answering the question, you can ignore everything before the assumptions.
-- When the pilot hit the snow, he was allegedly falling at 50 m/s.
-- His mass is 85 kg.
-- So his kinetic energy was (1/2) (mass) (speed squared) =
(1/2) (85) (50)² = <em>106,250 joules</em>
-- That's the energy that something else has to absorb in order to
reduce his speed to zero.
-- How far he fell, or what size crater he made in the snow, are irrelevant.
