Weight = (mass) x (acceleration of gravity where the object is)
You didn't tell us WHERE the boulder is, so I have to assume that it's on Mars, where the acceleration of gravity is 3.71 m/s².
675,000 N = (mass) (3.71 m/s²)
Mass = (675,000 N) / (3.71 m/s²)
<em>Mass = 181,941 kilograms</em>
The same weight on Earth would suggest a mass of only 68,807 kg, so you can see how important it is to know where you are when you make your measurements.
Answer:
Explanation:
The spring is stretched by .5 m and then released that means its amplitude of oscillation A is 0.5 m .
A = 0.5 m
After the release at one extreme point , the mass comes to rest again at another extreme point after half the time period ie
T / 2 = .3 s
T = 0.6 s
Angular velocity
ω = 
ω = 
ω = 10.45
Maximum velocity = ω A
ω and A are angular velocity and amplitude of oscillation.
Maximum velocity = 10.45 x .5
= 5.23 m /s
Magnetic fields point from north poles toward south poles.
<u>Explanation:</u>
- A magnetic compass doesn't highlight the geographic north pole. A magnetic compass focuses on the earth's magnetic poles, which are not equivalent to earth's geographic poles.
- About magnets, opposite poles attract each other. This reality infers that the north finish of a magnet in a compass is pulled in toward the south attractive posts, which lies close to the geographic north shaft. Attractive field lines outside of a lasting magnet reliably run from the north attractive shaft toward the south attractive post.
Answer:
much less than the mass of any terrestrial planet
Explanation:
According to www.wikipidia.com
The mass of all the objects of the asteroid belt, lying between the orbits of Mars and Jupiter, is estimated to be about 2.8–3.2×1021 kg, or about 4% of the mass of the Moon. Of this, Ceres comprises 0.95×1021 kg, a third of the total.
While mass of terrestrial planet is
5.97 x 1024 kg (which works out to 5,970,000,000,000 trillion metric tons) Earth is the most massive of all the terrestrial planets (www.universetoday.com)
By doing the calculation, mass of all the asteroid are much less than the mass of any terrestrial planet
