Answer:
mass of the other asteroid =
Explanation:
We use the definition for the force between two celestial objects under the action of the gravity they produce using newton's general gravitational constant:
The force between the two asteroids will then be given by:
where G is Newton's gravitational constant, the asterioid's masses are M1 and M2 respectively, and d is the distance between them.
We replace the known values in he equation above, and solve for the missing mass:
Since the units for the given quantities are all in the SI system, our resultant units for the unknown mass of the asteroid will be in kg.
Answer:
8381
Explanation:
Workdone=Force x distance
W= 289x 29
W=8381J
Answer:
Another term for planned economy is a socialist system.
Answer:
Linear expansivity is a property specific to a material and hence is constant.
Explanation:
Linear expansivity of the material will be constant irrespective of the shape and size of the material because it is a specific property.
It is a tendency of a material to expand in response to the increase in temperature.
The mathematical expression is given as:
where:
= change in temperature
L= initial length of the specimen
= linear expansivity
=change in length
Answer:
caves
Explanation:
Thermal stress causes the breaking of rocks caused by heating/cooling. You may choose deserts (due to heat) but if you think about it, there are not many rocks present compared to caves where it is more likely.
