18. An airplane with a weight of 11000 N cruises at 180 km/h in level flight 2300 m above the ground. How much lift is acting on the plane? 19. How much net force is produced by a 30.0 N force and a 20.0 N force under the following situations:

11000 N

Explanation:

Without lift, the plane would have a downward acceleration of 9.8 m/s².

But since the plane is cruising at a constant velocity, the lift must counteract the gravitational force so that the net force is zero, which would be 11000 N.

when cloud cover increases then the suns ray's which provides the earth with light and warmth gets covered due to the due to the suns ray's being blocked, the temperature in that region

therefore to conclude i would like to say that,

=more the cloud cover, the lesser the

happy to

pls mark as brainliest.

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.
