I would say C.
Developing a plan is important because it will motivate you and tell you when to get things done. It is the most efficient
Hope this helped :)
Answer:
The solution is given below:
Explanation:
The computation of the speed is shown below
As we know that
Speed = distance ÷ time
where
distance is 2000 km
And, the time is 2.5 hours
SO, the speed is
= 2,000 ÷ 2.5
= 800 km/h
Now the distance would be the same i.e. 2,000 km
but the time is 2 hours
So, the speed is
= 2,000 km ÷ 2 hours
= 1,000 km/hr
The direction should be opposite to the first airplane
Answer:
"A blackbody is an object that absorbs all of the radiation that it receives(that is,it does not reflect any light,nor does it allow any light to pass through it and out the other side).The energy that the blackbody absorbs heats it up,and then it will emit its own radiation."

Answer:
The electric force between them is 878.9 N
Explanation:
Given:
Identical charge
C
Separation between two charges
m
For finding the electrical force,
According to the coulomb's law

Here, force between two balloons are repulsive because both charges are same.
Where 

N
Therefore, the electric force between them is 878.9 N
