Answer:
a) the force goes down, b) The electric force is out of the screen
c) the force is zero
Explanation:
To determine the direction of a magnetic force we use the right hand rule. For a positive charge, the thumb is in the direction of speed, the fingers extended in the direction of the magnetic field, and the palm points in the direction of force. Let's apply this to our case
a) thumb to the right
Fingers spread out
And the force goes down
b) the electric force in the direction of the electric field if the charge is positive
Positive charge
Electric field out of the screen
The electric force is out of the screen
c) charge moving out screen
Magnetic field entered on the screen
Since they are parallel, therefore the force is zero
Answer:
435 m
Explanation:
The precision with which the distance to the source of the earthquake can be estimated is equal to the difference in distance covered by the S- and P-waves in the time of 0.125 s.
The distance covered by each type of wave is given by
where
v is the speed of the waves
t is the time
For S-waves,
v = 3.74 km/s
t = 0.125 s
So the distance covered is
For P-waves,
v = 7.22 km/s
t = 0.125 s
So the distance covered is
So, the precision with which the distance can be determined is:
Carbon dioxide
Helium
Argon
Hydrogen
Yes. because if there is a direction taken positive and the object is accelerating negatively it can bounce of a wall and change its direction so through an obstruction can it do that
