9 the only force acting on a 2.0 kg canister that is moving in an xy plane has a magnitude of 5.0 n. the canister initially has

a velocity of 4.0 m/s in the positive x direction and some time later has a velocity of 6.0 m/s in the positive y direction. how much work is done on the canister by the 5.0 n force during this time?

We don't need to know the magnitude of the force.

The canister's initial kinetic energy is (1/2) M V₀² = 16 joules.

Its final kinetic energy is  (1/2) M V₁² = 36 joules.

Its kinetic energy has grown by 20 joules.  The additional energy
must have come from the 5.0 N force, since that's the only force
acting on the canister.

PLEASE HELP!!! WILL GIVE 30 POINTS!! HAS TO BE CORRECT!
belka [17]

Answer:

Disruption to electricity power grid

Explanation:

We're looking a a solar flare. This will whip solar particles at high velocity into space and, If they are near earth, will interact with the earth's magnetic field. These magnetic changes will be measurable in the electric grid. Whether they are strong enough to cause "disruption" depends on a huge number of factors such as strength of and angles of the interacting magnetic fields and location of grid infrastructure,
