Work done = Force x Distance
Force = 10 lb = 44.5 N
Work Done = 44.5 N x 15 m
= 667.5 N-m
The temperature of the surface is between 3,500-20,00
supregiants would be around the top half for the y axis
and it would be a little in the middle for the x axis <span />
The experimental method is usually taken to be the most scientific of all methods, the 'method of choice'. The main problem with all the non-experimental methods is lack of control over the situation. The experiment method is a means of trying to overcome this problem. The experiment is sometimes described as the cornerstone of psychology: This is partly due to the central role experiments play in many of the physical sciences and also to psychology's historical view of itself s a science. A considerable amount of psychological research uses the experimental method. <span />
Answer:
N = 3600 N
Explanation:
centripetal acceleration requirement is
ac = v²/r = 20²/50 = 8 m/s²
As the only available acceleration is gravity, centripetal acceleration must come from that,
This makes the "weight" that the road senses and must counteract
N = m(g - ac)
N = 2000(9.8 - 8)
N = 3600 N
