Answer:
The work done on the canister is 15.34 J.
Explanation:
Given;
mass of canister, m = 1.9 kg
magnitude of force acting on x-y plane, F = 3.9 N
initial velocity of canister in positive x direction,
= 3.9 m/s
final velocity of the canister in positive y direction, 
The change in the kinetic energy of the canister is equal to net work done on the canister by 3.9 N.
ΔK.E = 
ΔK.E 
The initial kinetic energy of the canister;

The final kinetic energy of the canister;

ΔK.E = 29.79 J - 14.45 J
ΔK.E =
= 15.34 J
Therefore, the work done on the canister is 15.34 J.
c.E ps... that's the answerrr
Explanation:
that's the answer E
<h3>yes, there are human health risks caused by exposure to x rays</h3>
- describe the main risk (s) ::: - may cause damage to cells in the body
- large doses may lead cells to be cancerous
- causes mutations in the DNA
- describe common sources of exposure ( or overexposure ) :::
- natural background radiation e.g. - cosmic rays
- medical radiation e.g. - CT scans & medical x - rays
- man - made radiation e.g. - airport security scanners
- describe a technology, device, or behavior that can be used for protection, or to decrease exposure :::
- x - ray beam filters
- digital x - ray detectors
- technologies reduce radiation doses in radiography &
mammography

Static friction is the friction between an object at rest and the surface on which it is resting on.
Kinetic friction is the friction between a moving object and the surface on which it moves.
Hopefully you understood and this helps :)
