Explanation:
During an energy transfer, the collision loss for an electron can be determined by using the formula:
However; from the total stopping power & power loss of the electron;
where;
Z = atomic no. for lead = 82
E = 1.9 MeV
∴
radiational energy loss = collisional energy loss
= 0.19475
b)
Normally, the traditional lead shielding in its pure shape contains high brittleness. However, the functionality of this carbon group chemical element is useful for protection because it has an excessive density.
Initially, the conventional lead protection however reduces the mild clarity at the same moment as plexiglass is useful for light transmittance and readability.
Moreover, the traditional lead with its high density and thickness reduces observation features, in the meantime, the plexiglass is a whole lot higher than the stated.
Finally, plexiglass contains a high dimensional balance with an excessive dielectric constant.
Answers:
A: Angular velocity
B: Linear velocity
C: Linear Distance
Given:
Radius of the rope r=30cm=0.3m
Angular distance=10 revolutions
Time taken t=2seconds
To find:
A: Angular velocity in radians
B: Linear speed
C: Distance covered in 5 seconds
<u>Step by Step Explanations:</u>
Solution:
A: Angular velocity in radians;
According to the formula, Angular velocity can be calculated as
Angular Velocity = angular distance/ time
Where =Angular velocity
=Angular distance=10 revolutions
Changing revolutions to radians multiply with , so that we get
=62.80 rad/rev
=Change in time
Substitute the known values in the above equation we get
=62.80 / 2
B. Linear speed of the rope;
As per the formula
Linear speed = angular speed × radius
Where =Angular velocity
v=Linear speed of the rope
r=Radius of the rope
Substitute the known values in the above equation we get
C. Dsitance covered in 5 seconds;
Linear distance = linear speed × time
Where d= Linear distance of the rope
v=Linear speed of the rope
t=Time taken
Substitute the known values in the above equation we get
Result:
Thus A: Angular velocity of the rope
B Linear speed of the rope
C: Distance covered in 5 seconds
