The car should have less kinetic energy.
They are both going the same speed, but the truck is bigger and heavier. The more mass an object has, the more kinetic energy it has. There is more mass being moved, so it makes more kinetic energy. The car does not have as much mass, so it makes less kinetic energy compared to the truck.
Good luck with the rest of your test or quiz :)
Answer:
1.4 s
Explanation:
Given the following data;
Quantity of charge, Q = 2.5 C
Current = 1.8 A
To find the time required;
Mathematically, the quantity of charge passing through a conductor is given by the formula;
Quantity of charge, Q = current * time
Substituting into the formula, we have;
2.5 = 1.8 * time
Time = 2.5/1.8
Time = 1.4 s
Answer:
Sea salt is harvested by evaporating the ocean water away and generally has little to zero processing involved. Major sea salt manufacturers pump sea water into huge shallow “ponds” and allow the sun to evaporate the water... Before harvesting seawater, be sure the body of water you are using is not polluted.

Answer:
Time=15,Mass=3,Acceleration due to gravity=10,Height=50,Power=?.
Power=mgh/t.....which is 3×10×50=1500/15=100Watts.
Answer:
Explanation:
We shall represent all the forces in vector form .
Force of 95 pounds
F₁ = 95cos100 i + 95sin100j
= -16.5 i +93.55 j
force of 75 pounds
F₂ = 75cos200 + 75sin200j
= -70.47 i - 25.65 j
force of 146 pounds
F₃ = 146cos300 i + 146sin300j
= 73i -126.44 j
Resultant force
R = F₁+ F₂ + F₃
= -16.5 i +93.55 j -70.47 i - 25.65 j +73i -126.44 j
= -13.97 i - 58.54 j
Magnitude of R = √ ( 13.97² + 58.54² )
= 60.18
If Ф be angle of resultant with axis
tanФ = - 58.54 / -13.97
Ф = 76.57 + 180 = 256.57 , because both x and y components are negative. So the resultant will be in third quadrant.
