1) Time to get the highest point of it pathway>
Vf = Vo - g*t
Vf = 0 (condition of maximum height)
Vo = 5.33 m/s
g = 9.81 m/s
=> t = Vo / g = 5.33 m/s / 9.81 m/s = 0.543 s
2) Time to return from the highest point = time to get to the highest point = 0.543 s
Total time = 0.543s + 0.543 s = 1.086 s ≈ 1.09 s
Answer: 1.09 s
Answer:
The heat change of the system is 30 J.
Explanation:
Given;
increase in internal energy of a system, ΔU = 80 J
work done on the system, W = 50 J
The heat change of the system can be calculated from first law of Thermodynamics;
ΔU = Q - W
where;
Q is the heat absorbed by the system
W is the work done by the system (negative when work is done by the system and positive when work is done on the system)
Since work was done on the system the increase internal energy is given as;
ΔU = Q + W
ΔU - W = Q
80 J - 50 J = Q
30 J = Q
Therefore, the heat change of the system is 30 J.
Answer:
Plate tectonics is a scientific theory describing the large-scale motion of seven large plates and the movements of a larger number of smaller plates of Earth's lithosphere, since tectonic processes began on Earth between 3.3 and 3.5 billion years ago
Answer:
Explanation:
The tension in the cable would be then equal to the gravitational force that keeps the Moon in circular orbit around the Earth. So, we just need to calculate the magnitude of this force, which is given by:
where:
is the gravitational constant
is the mass of the Moon
is the mass of the Earth
is the distance between the Earth and the Moon
Substituting these numbers into the formula, we find:
