A bond with elements from B.
Hornblede the mineral which is made of more than one element is hornblende
Volume doesn't depend on what the substance is, only on how much of it there is.
Answer: A)
Explanation: when an electron is placed in a magnetic field, it experiences a force.
This force is given below as
F=qvB*sinθ
F = force experienced by charge.
q = magnitude of electronic charge
v = speed of electron
B= strength of magnetic field
θ = angle between magnetic field and velocity.
What defines the force exerted on the charge is the angle between the field and it velocity.
If magnetic field is parallel to velocity, then it means that θ=0° which means sin 0 = 0, which means
F = qvB * 0 = 0.
The charge being at rest has nothing to do with the angle between magnetic field strength and velocity.
P = density × gravity acceleration × height
P = 1200 × 9.81 × 15/100
P = 1765.8
