Answer:
they are like charges so they magnitude repulsive & direction will be ones left &ones right. but it depends on the axis of rotation.
Answer:
The solution of the given problem is provided in the following subsection.
Explanation:
According to the question,
The change in the height of the glacier will be:
= 
= 
Change in time,
= 5 years
Now,
The rate of change will be:
=
∵ (1 year = 12 months)
= 
= 
or,
The rate of change will be:
=
∵ (5 years in months = 5×12 months)
= 
= 
= 
Now, it's pretty simple. And if you meant "amber" as in "amp" and "volt" and in "voltage" maybe. Then this is simple.
An ampere (or amp) is a measure of the amount of electricity, called "current," in a circuit, while voltage (or volt) is a measure of the force behind that electricity's motion.<span> </span>
Answer:
The value is 
Explanation:
From the question we are told that
The radius is 
The coefficient of static friction is 
Generally the maximum safe driving speed is mathematically represented as

=> 
=> 
Answer:
So this is just a ratio/proportion problem
so lets say its in boys:minutes
so in the first scenario
20:8
and we want to find
x:10
So proportion really
20/8=x/10
cross multiply
25
25 boys can sweep it in 10 minutes
