Answer:
m g sin theta = force of object along incline due to gravity
N μ = frictional of incline on object where N is the normal force
N = m g cos theta force perpendicular to incline
m g sin theta = N μ = μ m g cos theta
μ = tan theta = tan 38 = .78
Solution:
<span>Starting with </span>g <span>equal to (1/0.6), solve for v.</span>
<span>v = 0.8c = 2.4E8 m/s</span>
Answer:
It takes 266 seconds to melt the ice.
Explanation:
Given data
- Power of the microwave oven (P): 125 Watt
- Heat supplied to the ice (Q): 33,200 Joule
- Time for the melting (t): to be determined
In order to determine the time required to melt the ice, we can use the following expression.
P = Q/t
t = Q / P = 33,200 J/ 125 W = 266 s
It takes 266 seconds to melt the ice.
