Answer is A. Because the telescope are use in night
Answer:
Half as large.
Explanation:
Using Newton's law of universal gravitation, if the mass of the planet is <em>M</em> and of the Moons 1 and 2 is <em>m</em>, them the force exerted by the planet on them will be:
Which clearly shows that the force that the planet exerts on the Moon 2 is half the force it exerts on the Moon 1.
Answer:
10 m/s
Explanation:
Velocity = frequency * wavelength
Velocity = 2.5 * 4
Velocity = 10 m/s
Answer:
varn=n1+1ehvkT–1
Explanation:
This is Einstein's equation.
Answer:
This is due to an increase in hydrostatic pressure, the force per unit area exerted by a liquid on an object. The deeper you go under the sea, the greater the pressure of the water pushing down on you.
