Answer:
0.0334N
Explanation:
Given parameters:
M1 = 5 x 10⁶kg
M2 = 1 x 10⁶kg
Distance = 100m
Unknown:
Gravitational force = ?
Solution:
To solve this problem, we use the Newton's law of universal gravitation.
Fg = 
G is the universal gravitation constant
m is the mass
r is the distance
Fg = 
= 0.0334N

(b) The negatve charge has a spherically symmetric charge distribution, concentric with the spherical shell
An entrepreneur would like their customers to come back, with this the customer service must be good. The owner’s workers must be kind & fair to the consumers. However good your product or service is, the simple truth is that no-one will buy it if they don't want it or believe they don't need it. And you won't persuade anyone that they want or need to buy what you're offering unless you clearly understand what it is your customers really want.
Knowing and understanding customer needs is at the centre of every successful business, whether it sells directly to individuals or other businesses. Once you have this knowledge, you can use it to persuade potential and existing customers that buying from you is in their best interests.
This guide tells you what you need to know about your customers, how to use this information to sell to them more effectively, and how to win business from your competitors.
b) Finding total distance :
Distance travelled from 0 s to 5 s :
Distance travelled from 5 s to 10 s :
Distance travelled from 10 s to 15 s :
- 150 + 1/2 x 5 x 5
- 150 + 12.5 = 162.5 m
Distance travelled from 15 s to 20 s :
- 36 x 5 + 1/2 x 5 x 4
- 180 + 10 = 190 m
Distance travelled from 20 s to 25 s :
- 45 x 5 + 1/2 x 5 x 5
- 225 + 12.5 = 237.5 m
Distance travelled from 25 s to 30 s :
- 40 x 5 + 1/2 x 10 x 5
- 200 + 25 = 225 m
Distance travelled from 30 s to 35 s :
- 20 x 5 + 1/2 x 20 x 5
- 100 + 50 = 150 m
Distance travelled from 35 s to 40 s :
Total = 75 + 150 + 162.5 + 190 + 237.5 + 225 + 150 + 50
Total = 1240 m
c) velocity at t = 15 s
d) average velocity
- 0 m/s (as displacement is equal to 0)
e) average speed
f) Part d uses displacement whereas part e uses distance
