Answer:
Mariner 10 in 1974 and 1975
Explanation:
Concave Mirror is a mirror with a curved reflecting surface that is bulging inward. This is the opposite of Convex Mirror which has a bulging outward surface. Concave mirrors are also called converging mirrors. The concave mirror reflected the light inward to a single focal point. These are usually used in reflecting telescopes.
Answer:
10m/s^2
Explanation:
Force = mass x acceleration
Acceleration = force/ mass
= 20000000/2000000
=10m/s^2
No fire uses oxygen sparks and flammable wood or whatever you choose to burn
According to the Law of Universal Gravitation, the gravitational force is directly proportional to the mass, and inversely proportional to the distance. In this problem, let's assume the celestial bodies to be restricted to the planets and the Sun. Since the distance is specified, the other factor would be the mass. Among all the celestial bodies, the Sun is the most massive. So, the Sun would cause the strongest gravitational pull to the satellite.
