If an airplane were traveling westward with a thrust force of 450 N and there was a headwind (drag) of 200 N, what would the res
Marat540 [252]

Answer:

The resulting net force on the airplane would be 250N.

Explanation:

It would be 250N because to find the amount of Newtons you would have to do 450 minus 200. 450 minus 200 equals 250. You can check by adding 200 plus 250 and it equals 450 the which is the "thrust".

A 5 kg rock is raised 28 m above the ground level. What is the change in its potential energy?
marin [14]
Let's assume that ground level is the height 0 meters. The change in potential energy is going to be gravitational potential energy, which is given by PE=mgh.
ΔPE=mgh-mgy
=mg(h-y)
=50(28-0)
=1400 J

a light bulb has a resistance of 360 . what is the current in the bulb when it has a potential difference of 120 v across it? 0.
xenn [34]
Presume we are looking for the current:

V = IR

120 = I*360

120/360 = I

1/3 = I

I = 1/3 = 0.333..

Current ≈ 0.33 Ampere.
