Answer:
repulsion force es R = 5,224 10⁻³ N
Explanation:
We use Newton's second law to add forces, the elective force is repulsive because the asteroids have the same type of charge and gravitational force is always attractive.
Gravitational force
Fg = G m1 m2 / r²
Fg = 6,673 10⁻¹¹ 5.7 10⁴ 5.5 10⁴/190²
Fg = 5,795 10⁻⁶ N
Electric force
Fe = k q1 q2 / r²
Fe = 8.99 10⁹ 14.0 10⁻⁶ 15.0 10⁻⁶ / 190²
Fe = 5.2296 10⁻³ N
The resulting force is
R = Fe - Fg
R = 5.2296 10⁻³ - 5.795 10⁻⁶= 5229.6 10⁻⁶ - 5,795 10⁻⁶
R = 5,224 10⁻³ N
this is a repulsive force and the asteroids move away from each other
Answer:
All living organisms have complex organization, they are able to grow and develop, they are able to reproduce and pass on genetic information to their offspring, they are able to acquire and release energy, and they are able to maintain stable internal environments.

Answer:
1
Explanation: that is the ratio
The power the swimmer must provide to overcome that drag force is 50 W.
<h3>What is work done?</h3>
Work done is equal to product of force applied and distance moved.
Work = Force x Distance
Given is an athlete, swimming at a constant speed, covers a distance of 203 m in a time period of 5 minutes and 50 seconds = 350 seconds. The drag force exerted by the water on the swimmer is 86.0 N.
Work done by drag force is W= F x d
So, W = 86 N x 203 m
W = 17.458 kJ
Power , a swimmer is provided P = Work done/ Time
P = 17458 / 350
P = 50 W
Thus, the power, the swimmer must provide to overcome that drag force is 50 W.
