We have that for the Question, it can be said that the amount by which the length of the stack decreases is
From the question we are told
A copper (<em>Young's modulus </em>1.1 x 1011 N/m2) cylinder and a brass (Young's modulus 9.0 x 1010 N/m2) cylinder are stacked end to end, as in the drawing. Each <em>cylinder </em>has a radius of 0.24 cm.
A compressive force of F = 7900 N is applied to the right end of the brass cylinder. Find the amount by which the length of the stack <em>decreases</em>.
Generally the equation for <em>copper </em>cylinder is mathematically given as
Generally the equation for brass<em> </em>cylinder is mathematically given as
Therefore Total change in length

At a speed of 0. 93 ccc, a spaceship travels to a star that is 8. 5 ly distant part and according to a scientist on earth 2.3 years the trip takes.
Spacecraft
A spacecraft is a vehicle or machine designed to fly in outer space. A type of artificial satellite, spacecraft are used for a variety of purposes, including communications, Earth observation, meteorology, navigation, space colonization, planetary exploration, and transportation of humans and cargo.
Satellites, rovers, and space stations are collectively referred to as spacecraft. In science fiction, a big, manned spacecraft that is not a satellite is commonly referred to as a spaceship.

The charge on the electron is 1.6x10^-19C. So, 10^24 of them will be a charge of 1.6x10^5C, F = q1xq2/[(4pi epsilon nought)r^2]
Answer:
Infra red waves, visible light waves,
Explanation:
Answer:
The gravitational potential energy of the man
= mass of the man(m) × gravitational acceleration(g) × height (h)
80 Kg × 9.8 m/s^2 × 60 m
80 × 9.8 x 60 ( kg ×m^2/s^2)
47040 Joules (ans)
