Answer:
Explanation:
For a charge moving perpendicularly to a magnetic field, the force experienced by the charge is given by:
where
q is the magnitude of the charge
v is the velocity
B is the magnetic field strength
In this problem,
So the force experienced by the electrons is
Answer:
112m/s
Explanation:
14x8=112 therefore meaning the zebra would run 112m/s
Answer:
volcanic eruptions
Explanation:
The volcanic eruptions are the ones that manage to cause changes to the lithosphere by building up new material on the surface. Through the volcanic eruptions we have release of pyroclastic material on the surface, and more importantly and in much higher amount lava flows. The lava flows quickly cool off on the surface on the Earth, and as they do they pile up new layers of igneous rocks, thus new crust on the surface of the Earth, causing changes on the lithosphere and shaping it for the foreseeable future.
If it is a multiple choice question is C. Infrared waves do not carry enough energy to kill cancerous cells.
Answer:
Yes, ultraviolet light can turn a rubber into solid due to prolong exposure.
Explanation:
A rubber is a material with an elastic property, causing it to be deform by an external force but takes its shape when the force is removed. Light is an electromagnetic wave which causes the sensation of vision. It transfers energy to a medium during propagation through the medium.
Generally, most light do not cause hardness of a rubber. But an ultraviolet light can cause rubber to become solid over a period of time. This is possible if there is a prolong exposure of the rubber, and because of the evaporation of volatiles in the polymer material. Ultraviolet light are known to cause a rubber to become solid.
