Igneous intrusions form when magma cools and solidifies before it can reach the surface. An extrusion consists of extrusive rock; which forms above the surface of the crust.
W = F x d
F: 450 N
d = 10 m
plug your variables into the equation to get W = 450N x 10m
Answer:
True
Explanation:
The force on the electron when it enters in a magnetic field is given by
F = q ( v x B)
F = -e x V x B x Sin∅
here, F is the force vector, B be the magnetic field vector and v be the velocity vector.
If the angle between the velocity vector and the magnetic field vector is 0 degree, then force is zero.
When the electrons enters in the magnetic field at any arbitrary angle, it experiences a force and hence it accelerate up.
One takes longer to slow down than the other because one has more mass(the train) compared to the bowling ball!
Answer:
Explanation:
The Newton's law in this case is:
Here, is the air temperture, C and k are constants.
We have
