Answer:
R^3 = GM / ω^2
R^3 = (6.67 * 10^-11) * (5.98 * 10^24) / (0.00007272)^2
R^3 = 7.54 * 10^22
R = 42,251,269
R = 4.225 * 10^7 m
4.225 * 10^7
Explanation:
The force that one massive object exerts to attract another object is called gravity or gravitational pull.
a) Speed of the Moon: 1025 m/s
The speed of the moon is equal to the ratio between the circumference of its orbit and the orbital period:
where
is the radius of the orbit of the Moon
is the orbital period
Substituting into the formula, we find
b) Centripetal force:
The centripetal force acting on the Moon is given by:
where
is the mass of the Moon
is its orbital speed
is the radius of the orbit
Substituting into the formula, we find
c) Gravitational force
The only relevant force that acts on the Moon, and that keeps the Moon in circular motion around the Earth, is the gravitational force exerted by the Earth on the Moon. In fact, this force "pulls" the Moon towards the Earth, so towards the centre of the orbit of the Moon, therefore it acts as source of centripetal force for the Moon.
Answer:
yes inertia would cause you to crash into the windshield in an accident
85 decibels or higher can cause damage to the human ear.
Decibels is the value of the measurement of sound. Hearing loss can be caused
by noise coming from a loud sound. Noise induced hearing loss maybe permanent
loss or temporary loss. Examples of activities that can give you a noise induced
hearing loss is target shooting, listening to music in your earphones that have
a high volume, and using lawnmowers.
