Answer:
See below
Explanation:
Possible.....mass is the amount of matter an object has ....weight is the result of gravity on an object.... different gravity ( Earth , Moon or Mars etc)
results in different weights .
Answer:
14.4kJ
Explanation:
Work = Force x distance
W × h = mgh
Given that,
mass m, = 59.5kg
acceleration due to gravity = 9.8m/s^2
height ,h = 16.2cm
convert to m is 0.162m
How much work = m x g x h
height is 0.162 x 152 steps
h = 24.624m
work = 59.5 x 9.8 x 24.624
= 14,358.25Joule
= 14.4kJ
Answer: D. 0.57
Explanation:
The formula to calculate the eccentricity
of an ellipse is (assuming the moon's orbit in the shape of an ellipse):

Where:
is the apoapsis (the longest distance between the moon and its planet)
is the periapsis (the shortest distance between the moon and its planet)
Then:


This is the moon's orbital eccentricity
Answer:
Stars emit colors of many different wavelengths, but the wavelength of light where a star's emission is concentrated is related to the star's temperature - the hotter the star, the more blue it is; the cooler the star, the more red it is
