The answer to this question is A. As the gas gets hotter, the molecules gain energy and move farther apart, causing the gas to expand. This is because, whenever you heat a substance, (solid, liquid, or gas), the molecules in the substance will always move more rapidly causing the substance to expand and the molecules to move further away from one another.
Answer:
The steam engine of James watt is more efficient than Newcomen ans more suitable for the industrial revolution.
Explanation:
James Watt is more widely know for working steam engine because Watt has created better engine which is suitable for the industrial revolution. The steam engine of James watt is more efficient than Newcomen. Watt developed the condensing arrangement by using piston which lessen the initial pressure leading to effectively worked than Newcomen's
Answer:
98 m √
Explanation:
How about s = Vo * t + ½at² ?
s = h = Vo * 2s - 4.9m/s² * (2s)² = 2Vo - 19.6
and
h = Vo * 10s - 4.9m/s² * (10s)² = 10Vo - 490
Subtract 2nd from first:
0 = -8Vo + 470.4
Vo = 58.8 m/s
h = 58.8m/s * 2s - 4.9m/s² * (2s)² = 98 m
Answer:
5 N right
Explanation:
Fx = 9N-4N
Fx = 5N
Since we can define the x and y axis. We have x to the right as positive.
