Answer:
a) is the speed of each proton
b)
Explanation:
Given:
radius of path of motion,
we know charge on protons,
magnetic field strength,
we've mass of proton,
a)
From the equivalence of magnetic force and the centripetal force on the proton:
where:
v = speed of the proton
is the speed of each proton
b)
Now the centripetal force on each proton:
<h3>Answer:</h3>
A. The image is larger than the object and the image is real.
Answer:
6.91 Hz
Explanation:
Volume of the cube
= (1.5 x 10⁻² )³m³
= 3.375 x 10⁻⁶ m³
mass of the cube
= 3.375 x 10⁻⁶ x 8920 ( 8.92 g / cm³ = 8920 kg/m³ )
m = 30.105 x 10⁻³ kg
Spring stretches by 2.65 x 10⁻² m due to a force of 1.5 N.
If k be the force constant
k x = F
K x2.65 x 10⁻² = 1.5
k = .566 x 10² N / m
Now frequency of oscillation for spring - mass system is given by
n =
=
n = 6.91 Hz
Increase because the mass of an object aligns with its weight
