The x-component of the normal force is equal to <u>1706.45 N.</u>
Why?
To solve the problem, and since there is no additional information, we can safely assume that the x-axis is parallalel to the hill surface and the y-axis is perpendicular to the x-axis. Knowing that, we can calculate the components of the normal force (or weight for this case), using the following formulas:
Now, using the given information, we have:
Calculating, we have:
Hence, we have that the x-component of the normal force is equal to <u>1706.45 N.</u>
Have a nice day!
Answer:
Explanation:
Given that,
Heat required, Q = 8000 J
Mass, m = 400 g
The change in temperature,
The heat required due to change in temperature is given by :
So, the specific heat of the substance is
