Answer:
energy
Explanation: transferred from the warmer object to the cooler one. The movement of thermal energy from a substance at a higher temperature to one at a lower temperature is called heat. When a substance is heated, it gains thermal energy. Therefore, its particles move faster and its temperature rises.
Answer:
I=8 Nw.s
Explanation:
Impulse
It is a physical magnitude that measures the force applied to an object by the time that force is acting. It produces a change in the momentum of the object, which is expressed in the following formula
We know the bat applies a force on the ball of F=400 N during t=0.02 sec, thus the impulse is
Answer: C) Unscrew one light. If the other lights turn off, it's a series circuit.
Explanation:
In a series circuit, all the components in the same path. The current in the entire circuit is same. The voltage drop across each component is different. If one component does not work, the entire circuit breaks and other components also stop working. On the other hand, in a parallel circuit, voltage drop across all the components is equal. Trouble in one component does not effect other components.
Hence, to check whether the lights are connected in series or in parallel, one light should be unplugged and if the other lights still work, it means they are connected in parallel otherwise in series. Thus, correct option is C) Unscrew one light. If the other lights turn off, it's a series circuit.
there is 1000 grams in 1 kilogram
Divide
80/1000 = 0.08
0.08 kilograms is your answer
hope this helps
