Represent a vector of 100 N in North-East direction
1 answer:
Answer:
please find the attachment to this question.
Explanation:
In this question, we represent the 100N in the North-East direction, but first, we define the vector representation:
It is generally represented through arrows, whose length and direction reflect the magnitude and direction of the arrow points. In this, both size and direction are necessary because the magnitude of a vector would be a number that can be compared to one vector.

Explanation:
We have, a pendulum on a planet, oscillates with a time period 5 sec. The formula used to find the time period is given by :
l is length of the pendulum
g is acceleration due to gravity on which it is placed
It is clear that, the time period of pendulum is independent of the mass. Hence, if the mass is increased six times, its time period remains the same.
Answer:
The magnitude of the acceleration of the boy toward the girl is
Explanation:
It is given that,
Mass of the boy,
Mass of the girl,
The acceleration of the girl toward the boy is,
To find,
The acceleration of the boy toward the girl.
Solution,
Let is the magnitude of the acceleration of the boy toward the girl. We know that force acting on one object to other are equal in magnitude but opposite in direction. So,
So, the magnitude of the acceleration of the boy toward the girl is
