Answer:
I guess the answer is charging by friction
Answer:
The done by the vertical component of force is zero.
Explanation:
Given data,
The mass of the textbook the women pushes horizontally, m = 3.2 kg
The displacement of the textbook, S = 3.5 m
Let the force of the women acts on the book horizontally,
Therefore, the horizontal component of force is maximum and the vertical component is zero.
If F is the force applied by the women, then the horizontal and vertical component of the force is,
Since the force is acting along with the horizontal x component, the vertical component of the force is zero.
Hence, the done by the vertical component of force is zero.
Answer:
Explanation:
Heat capacity is related to a substance's ability to retain heat and the rate at which it will heat up or cool. For example, a substance with a low heat capacity, such as iron, will heat and cool quickly, while a substance with a high heat capacity, such as water, heats and cools slowly.
Answer:
60 m/s
Explanation:
acceleration: 1/2 m/s2
time: 2 minutes
there are 60 seconds in one minute so
60sec x 2 min = 120 sec
1/2 in decimal form is 0.5 so 0.5 x 120sec= 60m/s
