Answer:
Explanation:
The gravitational force between two objects is given by
where
G is the gravitational constant
m1, m2 are the two masses
r is the separation between the two masses
In this problem, we have
the mass of each truck
r = 2.0 m is their separation
Substituting,
Answer:absorbs and emits electromagnetic radiation at all wavelengths
Explanation:
A blackbody is a believed to be a perfect absorber and reflector of radiation. Blackbody, in physics, refers to a surface that absorbs all radiant energy that falls on it. It is supposed that because incident visible light will be absorbed rather than reflected, the surface will appear black.
Answer:
E) a billion times brighter
Explanation:
- <u>The sun is a star, which is about billion times brighter as the reflected light from any planet orbiting around it. </u>
- The brightness is based on its composition and its position from the planet. The sun happens to be the brightest star on the Earth's sky which is about 13 billion times brighter than the next brightest star.
<em>m = 4.3 kg</em>
<em>Hi there ! </em>
<em>use formula</em>
<em>G = m×g => m = G/g</em>
<em>g ≈ 10N/kg</em>
<em>replace G ; g</em>
<em>m = 43N/(10N/kg)</em>
<em>m = 4.3 kg</em>
<em>Good luck !</em>
B, because gold is the most malleable substance of all.
