Answer:
Explanation:
With a initial velocity is zero, kinematics equation is:
It would have 45 protons, as the atomic number is equivalent to the amount of protons
Answer:
the work done by the 30N force is 4156.92 J.
For this problem, they don´t ask you to determine the work of the total force applied in the block. They only want the work done for the force of 30N, with an angle of 30º respectively of the displacement and a traveled distance of 160m. So:
W=F·s·cos(α)=30N·160m·cos(30º)=4156.92J
Answer:
W = 47040 J
Explanation:
Given that,
The mass of a student, m = 60 kg
Height of the tower, h = 80 m
We need to find the work done in climbing the tower. The work done is given by :
W = mgh
So,
W = 60 × 9.8 × 80
W = 47040 J
So, the required work done is 47040 J.
Explanation:
Edothermic process is the absorbtion of heat.
It is the opposite of exothermic process which is the release of energy. In edothermic process thermal energy is absorbed from the surrounding
