Answer:
I = 0.0025 kg.m²
Explanation:
Given that
m= 2 kg
Diameter ,d= 0.1 m
Radius ,
R=0.05 m
The moment of inertia of the cylinder about it's axis same as the disc and it is given as
Now by putting the all values
I = 0.0025 kg.m²
Therefore we can say that the moment of inertia of the cylinder will be 0.0025 kg.m².
Answer:
0.114m
Explanation:
From the general expression for the radius of the proton's resulting orbit, we have
where q is is the charge of the proton
m is the mass of the proton
B is the magnetic field
and v i the speed.
to determine the speed, we use the expression
Kinetic Energy=
where <em>V </em>is the voltage value i.e 1.0kv
and v is the speed
Hence, from simple rearrangement we have the speed v to be
if we substitute value, we have
carrying out careful arithmetic we arrive at
.
using the value for the speed in the expression for the radius of the orbit as stated earlier, we have
The final velocity before takeoff is 104.96 m / s.
<u>Explanation:</u>
The last velocity of a given object over some time defines the final velocity. The final velocity of the object is given by the product of acceleration and time and adding this product to the initial velocity.
To calculate the final velocity,
V = u + at
where v represents the final velocity,
u represents the initial velocity,
a represents the acceleration
t represents the time taken.
v = 104.96 m / s.
