Answer:
false
Explanation:
every object will always have the force of gravity acting upon it.
Answer:
the action of measuring something.
Answer:
Jupiter
Explanation:
Since the mass of Jupiter is the greatest from the given choices, it will exert the most force on any object orbiting 100km above its surface.
This is compliance with the Newton's law of universal gravitation which states that "the force of attraction between two bodies is directly proportional to the magnitude of their masses and inversely proportional to the distances between them".
- Therefore, the more the masses of two bodies, the higher the gravitational attraction
- Since the distance is the same, the planet with the greater mass will exert the most force on the satellite.
Answer:
its an interaction that can move an object; push or pull makes it or gravity, magnetism
Explanation:
its all in the answer
Answer:
a) 800 km
b) 9.79° & 12.47°
Explanation:
It is known that the wavelength of any material or substance is given by the relation 入 = v/f
From the question, the time between the crest is given as 1.0 h, therefore, t = 1.0 h
Also, remember that frequency, f can be represented by
f = 1/t, and thus,
f = 1/1.0 h = 1.0 h^-1. This is our frequency, and would be used in the primary stated formula
入 = v/f, from the question, the speed is already stated as 800 km/h, so we apply directly
入 = 800 / 1
入 = 800 km. Therefore, the wavelength of the tsunami is 800 km
B,
the smallest angle between the Southern tip of Africa is
Sinθ = 800 / 4500
Sinθ = 0.17
θ = Sin^-1 0.17
θ = 9.79°
The smallest angle between the Southern end of Australia is
Sinθ = 800 / 3700
Sinθ = 0.216
θ = Sin^-1 0.216
θ = 12.47°
