Answer:
Explanation:
Let the potential difference between the middle point and one of the plate be ΔV .
electric potential energy will be lost and it will be converted into kinetic energy .
Electrical potential energy lost = Vq , where q is charge on charge particle .
For proton
ΔV× q = 1/2 M V² ( kinetic energy of proton )
where M is mass and V be final velocity of proton .
For electron
ΔV× q = 1/2 m v² ( kinetic energy of electron )
where m is mass and v be final velocity of electron . Charges on proton and electron are same in magnitude .
As LHS of both the equation are same , RHS will also be same . That means the kinetic energy of both proton and electron will be same
1/2 M V² = 1/2 m v²
(V / v )² = ( m / M )
(V / v ) = √ ( m / M )
In other words , their velocities are inversely proportional to square root of their masses .
The magnitude is 53N and the direction is 3 degrees. I hope this helps!
To solve this problem it is necessary to apply the concepts related to simple harmonic movement.
The maximum speed from the simple harmonic motion is given as
Where,
K = Spring constant
m = mass
At this case m is a constant then
then the ratio is given by
According the statement,
Therefore the maximum speed becomes double: 2) It would increase by a factor of 2.
The pressure can be solved using the following formula:
P = mg / A
Where: P = pressure
mg = mass * gravity = W = 10.5 N
A = l*w
Solving for A (maximum):
A = 8*3
A = 24 sq. cm
Solving for A (minimum):
A = 15*8
A = 120 sq. cm
Substituting into the first equation:
Pmax = 10.5 N / 24 sq.cm
Pmax = 0.4375 Pa
Pmin = 10.5 N / 120 sq.cm
<span>Pmin = 0.0875 Pa</span>
B because whales do not have 4 legs, the fossils of whales don't look like fossils of four legged mammals, and migration patterns just doesn't sound right
