Just to give you a sense of scale, Jupiter is 2.5 times more massive than all the rest of the planets in the Solar System combined. Jupiter's diameter is 11.2 times larger than Earth. Jupiter is a very gaseous planet. The temperature of the early solar system explains why the inner planets are rocky and the outer ones are gaseous. As the gases coalesced to form a protosun, the temperature in the solar system rose.
Answer:
0.83m/s
Explanation:
Given parameters:
distance = 1000m
time taken = 20min
Unknown:
Speed of the walking person = ?
Solution:
To solve this problem;
Speed = 
Time taken should be in seconds;
1 min = 60s
20min = 20 x 60 = 1200s
Speed = 
= 0.83m/s
Gravitational force = Gxm1xm2 /r^2
This equation depends only upon object's masses and distance between them. So option b is correct
If the wavelength increases (gets longer), then the frequency <em>decreases</em>.
(A wave occurs less often.)
