Answer:
dude just use the calculator fr
Normal force. Normal force is always present when there is contact between two items. Normal force is counteracting the gravitational force.
Explaining the incorrect answers:
-It’s not frictional force because friction only occurs when something is moving and also making contact. While there is contact in this scenario, the apple is not moving.
-There is no applied force; that would be something like a push.
-There is a gravitational force on the table, but it doesn’t keep the apple’s push in check. They are both pointed downwards, to the earth.
Hope this helps!

Answer:
B = 4.5 x 10⁻⁷ T = 0.45 μT
Explanation:
From Ampere's law the magnetic field at a certain radius from straight current-carrying wire is given by the following formula:
where,
B = magnetic field = ?
= permeability of free space = 4π x 10⁻⁷ H/m
I = current = 180 A
r = radius = 80 m
Therefore,
<u>B = 4.5 x 10⁻⁷ T = 0.45 μT</u>
