Answer:
Explanation:
Given data
Mass m=2.0 kg
Magnitude of force F=5.0 N
Initial velocity Vo=8.0i m/s
Final velocity Vf=10.0j m/s
The change in the kinetic energy of canister equals to net work done on the canister
So
ΔK=Wnet
Kf-Ki=Wnet
For initial kinetic energy
For final Kinetic energy
Work done on canister by 5.0N force is given as:
Answer:
each resistor draws 1/3 of an amp or 0.33333 amps
Explanation:
V = I * R
V = 10 volts
R = 30 ohms
10 = I * 30 Divide by 30
10/30 = I
I = 0.33333
D. All of the above
This is true because scientific laws are all 3:
• They are well tested (to become a definite law)
• They are usually in equation form; for example: (e=mc^2)
• They are usually an example of a scientific model. The model generally will demonstrate the principle.

<span>There are several ways to change the frictional force between two objects. The first one is to modify the surfaces of each object that will come in contact with each other. The smoother they get, the less friction there will be. But if the surfaces become rougher, more friction will be generated. If you don’t want to alter the surfaces, you can simply add lubrication to reduce friction.</span>
