An eagle descends steeply onto its prey. its weight (the gravitational force on the eagle), of magnitude 60.0 n, points downward in the -y-direction. the left force exerted on the eagle's wings by the air, also of magnitude 60.0 n, is at an angle of 20.0∘ from the vertical (the +y-direction) and 70.0∘ from the +x-direction. the drag force (air resistance) exerted on the eagle by the air has magnitude 15.0 n and is at an angle of 20.0∘ from the -x-direction and 70.0∘ from the +y-direction. find the x- and y-components of the net external force f⃗ on the eagle.

grav potential energy

when a device is used in a circuit in which the voltage is 81 v, the current flowing through the device is 3 a. what is the resistance of the device?

a. 27 ω

b. 40.5 a

c. 243 ω

d. 243 a

the correct answer is a. 27

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
