B. False
Endothermic reactions absorb heat.
We are asked in what manner can one make the motor run in reverse. One way to do so is to flip the magnet on the other side so that the opposite charge faces to the motor. The magnetic field induced by the magnet to the motor results to a reactive force opposite to the induced motion.
Answer:
Anything in an experiment that remains unchanged.
Explanation:
An example could be the temperature of the laboratory room. If there is something that has an effect on an experiment that is not variable, it is a constant. Another constant could be, say, if you were doing calculations with the same amount and kind of fluid throughout the experiment, then that fluid would also be a constant.
The angular position of the wheel at t = 2. 0 s is 4.5 rad.
Angular Position:
When an object is undergoing a rotational motion, then the orientation of the object with respect to a specific reference position is known as angular position.
Given data:
The angular acceleration of the object at initial is, α = - 0.40 rad/s².
The angular velocity of the object is, ω = 1.5 rad/s.
The angular position of the object at initial is,
.
The time interval is, t = 2.0 s.
The expression for the angular position of the wheel at t = 2.0 s is,

Solving as,

Thus, we can conclude that the angular position of the wheel at t = 2. 0 s is 4.5 rad.
