The first requirement is to
look at all the vital information’s given in the question. Based on those
information’s the answer to the question can be easily reached.
Distance that needs to be covered for the race = 38.4 kilometer
Time required to complete the race = 4.5 hours
Then
Average speed = Distance/Time
= 38.4/4.5 km/hour
= 8.53 km/hr
So the average speed would be 8.53 Km/hr.
I hope the answer to the
question is what you were looking for and the procedure is clear to you.
Answer:
1 m/s
Explanation:
Impulse = Change in momentum
Force × Time = Mass(Final velocity) - Mass(Initial Velocity)
(1.0)(1.0) = (1.0)(Final Velocity) - (1.0)(0)
Final velocity = <u>1 m/s</u>
First of all I can't write the story for you but I can help you brain Storm.
1. Choose the character you know the most about If you know Super Hero's,Cartoons etc. use what you know then it won't look like you're randomly throwing things in.
2. Figure out witch part of the brain you want to talk about, the facts you want to put in there, and organize your facts.
3. Put it in little kid language, use small words and not BIG words 5-6 year old's have a good Vocabulary but it is better to use small words.
Ok hope you have fun writing this story!
Answer:
The magnitude of the resultant decreases from A+B to A-B
Explanation:
The magnitude of the resultant of two vectors is given by
where
A is the magnitude of the first vector
B is the magnitude of the second vector
is the angle between the directions of the two vectors
In the formula, A and B are constant, so the behaviour depends only on the function . The value of are:
- 1 (maximum) when the angle is 0, so the magnitude of the resultant in this case is
- then it decreases, until it becomes 0 when the angle is 90 degrees, where the magnitude of the resultant is
- then it becomes negative, and continues to decrease, until it reaches a value of -1 when the angle is 180 degrees, and the magnitude of the resultant is
