If its out and has been rained on it will rust if its like metal or iron stuff like that it will rust
the answer is rust
but no so quickly
The Coulomb’s law is expressed mathematically as:
F = k * q1 * q2 / d^2
Where,
F = force of attraction between 2 particles = 2.0 N
<span> k = Coulomb’s
constant = 8.988 * 10^9 N m^2 / C^2</span>
q = charge of the particle
d = distance between the 2 particles = 1.35 m
Since the two coins have identical charges therefore q1 =
q2 =q
F = k* q^2 / d^2
2.0 N = (8.988 * 10^9 N m^2 / C^2) * q^2 / (1.35 m)^2
q =
2.01 * 10^-5 C
<span>Therefore each coins have charges equivalent to 2.01 *
10^-5 C.</span>
Answer:

Answer:
Hands rubbed together to become warm
Answer:
Explanation:
Given,
Mass of the truck, M = 1470 Kg
initial speed of the truck, u = 27 m/s
mass of car, m = 1010 Kg
initial speed of car, u' = 0 m/s
Final speed, V = ?
Using conservation of momentum
Change in kinetic energy
Change in KE =
