Answer:
3.6×10⁶ m
Explanation:
Newton's law of universal gravitation states that the force between two masses is:
F = GMm / r²
where G is the universal constant of gravitation (6.67×10⁻¹¹ m³/kg/s²),
M is the mass of one object
m is the mass of the other object,
and r is the distance between the center of masses of the objects.
The force acting on the meteor is:
∑F = ma
GMm / r² = ma
GM / r² = a
Given M = 6×10²⁴ kg and a = 4 m/s²:
(6.67×10⁻¹¹ m³/kg/s²) (6×10²⁴ kg) / r² = 4 m/s²
r = 10⁷ m
The distance from the meteor to the center of the Earth is 10⁷ m. We want to know what the height of the meteor is (distance to the surface of the Earth). So we need to subtract the Earth's radius.
h = 10⁷ m − 6.4×10⁶ m
h = 3.6×10⁶ m
Answer:
Maximum speed of the coin, v = 0.607 m/s
Explanation:
It is given that,
A coin rests on a record 0.13 m from its center i.e. the radius of the circular path, r = 0.13 m
The coefficient of static friction between the coin and the record is, 
The centripetal force acting on the coin is balanced by the frictional force. Its mathematical relation is given by :
v = 0.607 m/s
So, the maximum coin speed at which it does not slip is 0.607 m/s. Hence, this is the required solution.

Answer:
c.) Their eligibility for social education services depends on whether their conditions adversely affect their educational functioning.
Explanation:
Chronic Illness is a human health condition in which a particular (or number of) illness is persistent in the body and the effects on the body are long-lasting and are often resistant to treatment. The word chronic is usually used when the disease/illness/sickness and its effects stay in the body for more than three months.
The likeliest answer from the options given is option C because before social education services are given, it has to be decided if their health condition adversely affects their education.
