Since the two trains are passing in opposite
directions, so this means that their relative velocities will be the sum of the
two trains that is:
<span>
relative velocity = (13 + 28) = 41m/s</span>
<span>
a. The passengers aboard on train B will see that train A is
moving at 41m/sec due east</span>
<span>b. The passengers aboard on train A will see that
train B is moving at 41m/sec due west</span>
Answer:
12N to the right.
Explanation:
There is a force of 12N upwards and a force of 12N downwards: these cancel out.
Assign a negative value to forces towards the left, and a positive value to the forces towards the right: -3N and +15N
Combine them: -3N+15N = 12N
The net force has a magnitude of 12N, and since our answer was positive, it acts towards the right.
Answer:
47347.1936 milligrams per centimeter
Explanation:
1 pound is equal 453592 milligrams.
one meter is 100cm
10.43*453952/100= 47347.1936milligrams per cm
Gravitational field strength is another name of acceleration due to gravity which can be given by dividing the gravitational force on an object by its mass.
The formula can be given as
where E = gravitational field
= force of gravity
m = mass of the object.
hence the correct choice is
1) Fg/m
