Answer: Final Temperature= 40.57 deg C; Latent Heat of Fusion of Ice= 80.14 cal/g
Explanation:
The system is said to be isolated to the surroundings. All energy must remain inside the system. We can state that no loss of energy takes place, thus,
Voting, running, speaking in front of government
You are exerting 100N. Since there’s no NET force, then there must be exactly 100N pushing exactly back on your 100N to cancel it to exactly zero. Newton's first law states that whether a body is at rest or travelling in a straight line at a constant speed, it will remain at rest or continue to move in a straight line at a constant speed unless acted upon by a force.
First, let us assign the variables
y = 0.90 m, x= 15 m,
= 2.80 m
s= required
The vertical component of the trajectory is in uniformly accelerated motion. The equation is:
, while the horizontal component is
. Also,
since the object starts from rest (with respect to the downward motion). a is negative because it is moving downwards (a = -9.81 m/s^2). Substituting,
The magnitude of v0, which is speed (s), is equal to 24.1 m/s
Answer:
570 J
