Answer:
C. 100 mph west
Explanation:
Average velocity is total displacement over total time. During the first hour, the average velocity is:
v_avg = 100 mi / 1 hr
v_avg = 100 mph west
Since the velocity is constant, the instantaneous velocity at any time equals the average velocity.
v = v_avg
v = 100 mph west
Answer:
30 m/s
Explanation:
Velocity is 
since we know that the initial velocity is 0, and the acceleration is 
then we also know that time is 3 seconds it follows that: 
Electrical to light & electrical to sound (in commentry) & sometimes battery loudspeakers are used so chemical to sound
Answer:
Conduction is heat transfer through stationary matter by physical contact. (The matter is stationary on a macroscopic scale—we know that thermal motion of the atoms and molecules occurs at any temperature above absolute zero.) Heat transferred from the burner of a stove through the bottom of a pan to food in the pan is transferred by conduction.
Convection is the heat transfer by the macroscopic movement of a fluid. This type of transfer takes place in a forced-air furnace and in weather systems, for example.
Heat transfer by radiation occurs when microwaves, infrared radiation, visible light, or another form of electromagnetic radiation is emitted or absorbed. An obvious example is the warming of Earth by the Sun. A less obvious example is thermal radiation from the human body. I hope this helps you
