Answer:
(-6,8)
Explanation:
Since v has direction as u, it must be a multiple n of u.
therefore v = (3×2, 4×2) = (-6,8)
Answer:
<u>Charge</u><u> </u><u>of</u><u> </u><u>the</u><u> </u><u>particle</u><u> </u><u>is</u><u> </u><u>1</u><u> </u><u>coulomb</u><u>.</u>
Explanation:
Force, F:
F is magnetic force.
B is the magnetic flux density.
e is the charge of the particle.
V is the velocity
When the roller coaster moves down from the top of the hill, all of its stored potential energy is converted into kinetic energy to move it and when it goes back up the hill it turns kinetic into potential.
The density of the object is approximately 1.91 kg per m³.
42 kg is a measure of mass, and 22 m³ is a measure of volume. Knowing this, you can use the relationship
to solve for the object's density.
42 kg
22 m³
1.91 kg per m³.
