Answer:
- d = 2; m = 2; m = 2
- d= 1; m = 1; m = 2
- d = 1; m = 1; m = 1
- d = 2; m = 1; m = 2
- d = 2; m = 1; m = 1
Explanation:
The following diagrams show five pairs of asteroids, labeled with their relative masses (M) and distances (d) between them. For example, an asteroid with M=2 has twice the mass of one with M=1 and a distance of d=2 is twice as large as a distance of d=1. Rank each pair from left to right based on the strength of the gravitational force attracting the asteroids to each other, from strongest to weakest.
- d = 2; m = 2; m = 2
- d= 1; m = 1; m = 2
- d = 1; m = 1; m = 1
- d = 2; m = 1; m = 2
- d = 2; m = 1; m = 1
54-(15x2) divided by 2 = 12
54 - 15 = 39
39-15=24
24 divided by 2=12

Answer:
40000N
Explanation:
Given parameters:
Mass of the car = 1000kg
Velocity of the car = 20m/s
Time taken = 0.5s
Unknown:
Force on the car = ?
Solution:
According to Newtons second law of motion:
F = m a
F is the force
m is the mass
a is the acceleration
F = m
Change in velocity = 0 - 20 = -20m/s
F = 1000 x = -40000N
The force on the car is 40000N
