Answer:
Explanation:
In order to calculate the angular momentum of the particle you use the following formula:
(1)
r is the position vector respect to the point (0 , 5.0), that is:
r = 0m i + 5.0m j (2)
p is the linear momentum vector and it is given by:
(3)
the direction of p comes from the fat that the particle is moving along the i + j direction.
Then, you use the results of (2) and (3) in the equation (1) and solve for L:
The angular momentum is -30 kgm^2/s ^k
The answer is 15 kilometers in 20 minutes.
Answer: B
EXPLANATION: the volume and temperature of the gas are directly proportional hence an increase in volume would lead to an increase in temperature and vice versa
Answer: im trying to find the same answer too
Explanation
Energy (C) is fully described by its magnitude.
There's nothing else about it to measure.
The other four things on the list are all vectors.
They need directions to go along with their magnitudes.
