Answer:
White or lighter colored, shirt REFLECTS most of the visible wavelengths or all colors of light while a black or dark shirt ABSORBS more wavelengths.
So, Absorbed radiation is converted into heat, making the darker or black shirt warmer to wear.

The answer is 0m because at point 8s the displacement is at zero m for example at 3s the displacement is at 8m
Answer:
It is Newton's first law of motion also referred to as the law of inertia.
Explanation:
Answer:
v=10.75m/s
Explanation:
It is given that,
Pete drives 215 Meters in 20 seconds. He is driving down 7th floor. We need to find his speed.
Speed = distance/time
⇒
Hence, the speed of Pete is 10.75 m/s.
Answer:
<em> -11,813.87N </em>
Explanation:
According to coulombs law, the Force between the two charges is expressed as;
F = kq1q2/d²
k is the coulombs constant = 9*10⁹kg⋅m³⋅s⁻²⋅C⁻².
q1 = -0.00067 C
q2 = 0.00096 C
d = 0.7m
Substitute into the formula:
F = 9*10^9 * -0.00067 * 0.00096/0.7²
F = 9*10⁹*-6.7*10⁻⁴*9.6*10⁻⁴/0.49
F = -578.88*10⁹⁻⁸/0.49
F = -578.88*10/0.49
F = -5788.8/0.49
F = -11,813.87N
<em>Hence the force between the two charges is -11,813.87N </em>
