X rays with the air in the atmosphere, solar radiation is the least powerful
Here is the answer of the given problem above.
Use this formula: <span>P = FV = ma*at = ma^2 t
</span><span>Substitute the values, and therefore, we got m(a0)^2t = m(x)^2 (2t)
then, solve for x which is the acceleration at 2t.
</span>The <span>answer would be a0/sqrt(2).
Hope this answers your question. Thanks for posting.

Answer:the will have the same acceleration
Explanation:according to fállelos theory they land at the same time
Answer:
G = 1.670 ×
Explanation:
From Newton's law of universal gravitation,
F =
Where F is the force of attraction, G is the gravitational constant, M is the mass of the earth, R is the radius of the earth.
From Newton's second law of motion,
F = mg
mg =
g =
⇒ G =
If the radius of the earth becomes half,
R = , then;
G =
Given that: g = 9.8 m/, radius of the earth is 6371000 m, mass of the earth is 5.972 × kg, then;
G =
= 1.670 ×
