The resistance, R to the motion of a car is partially constant and partly varies as the square of the speed, v. When the car is moving at 30km/h, the resistance is 650N and the car moving at 50km/h the resistance is 960N.
(a). find an expression for R interms of V
(a) the resistance at 80km/h​

i think it would be 5

80cm/s.

24cm/s.

53.3cm/s.

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.
