Answer:
1000
Explanation:
because if you multiple times a 100 you will get a 1000
Answer:
a) Acceleration of the car is given as
b) Acceleration of the truck is given as
Explanation:
As we know that there is no external force in the direction of motion of truck and car
So here we can say that the momentum of the system before and after collision must be conserved
So here we will have
now we have
a) For acceleration of car we know that it is rate of change in velocity of car
so we have
b) For acceleration of truck we will find the rate of change in velocity of the truck
so we have
It takes the spoon 5.38 seconds to transfer 25 j of heat energy to your hand.
Heat energy is created by the movement of tiny atoms, molecules, or ions in solids, liquids, and gases. It is possible to transfer heat energy from one thing to another. Heat is a flow or transfer that happens when two objects have different temperatures from one another.
Convection is the process of transferring heat through gases and liquids. The particles in heated air absorb heat energy, allowing them to move faster and farther apart while carrying the heat energy. Because warm air is less dense than cold air, it rises.
Cooler air rising from below replaces the air that has risen. When warm air rises and is again replaced by colder air, a convection current is created.

C: The wave moves energy through matter.
F: The wave transfers energy perpendicular to the motion of the wave.
Answer:
Florida's Cape Canaveral was central to the US victory in the space race. An isolated air force base was in Cape Canaveral near the ocean. This location allowed NASA scientists to test rockets freely.
