The amount of heat that is required to raise the temperature of a system is calculated by the expression:
Heat required = m Cp ΔT
Heat required = 500 g (1.0 calorie/gram °C) (10.0 <span>°C)
Heat required = 5000 calorie
The correct answer from the choices listed above is the second option.</span>
P=m d/dt v(t) if we increase the velocity of the object means we increase the momentum 'cause momentum is directly proportional to change in velocity.
Answer:
it is very hard question for me sorry i cant solve it
Both the velocity and acceleration are vector quantities. It means that this parameter does not only have magnitude, but also the direction of motion. The direction is incorporated by the + or - sign depending on the sign convention. In this case, the downward motion is + while the upward motion is -. Thus, the velocity is equal to +0.89 m/s while the acceleration is -2.92 m/s².
