D: Ultraviolet Rays is the answer hope that helps
The best answer is B)
Space technology helps improve life on Earth.
Many of the innovations developed by space programs had applicability beyond their original use. This is one such example, in which robotic technology used for servicing spaceships is helping to improve surgeries here on Earth.
Answer:
q = 2.65 10⁻⁶ C
Explanation:
For this exercise we use Coulomb's law
F =
In this case they indicate that the load is of equal magnitude
q₁ = q₂ = q
the force is attractive because the signs of the charges are opposite
F =
q =
we calculate
q =
q =
Ra 7 10-12
q = 2.65 10⁻⁶ C
Equation 1 :
m1 : m1a =T
Equation 2:m2 : m2a= F - T
Adding 1 and 2a=0.073
Placing in equation 1
we get T = 218.18N
