Answer:
v = 23.87 m/s
Explanation:
Given that,
The radius of wheels, r = 0.380 m
The wheels rotate once every 0.1 s
We need to find the linear velocity of the wheels. The linear velocity of a wheel is given by :
So, the required linear velocity of the wheel is equal to 23.87 m/s.
The electric field strength will be 0.6252 V/m. It is the strength at which the field is created by charges.
<h3>What is electric file strength?</h3>The electric field strength is defined as the ratio of electric force and charge.
The electric field strength is found as;
Hence, the electric field strength will be 0.6252 V/m.

Answer:
follows are the responses to the given question:
Explanation:
The kinetic energy of every object moving. any entity lifted against the strength of gravity stores elastic potential of gravity.
Its total power of an independent device stays constant underneath the Mass conservation on Energy and it is, the kinetic energy plus potential energy is just like a fixed . So, if KE improves, it is valid that PE declines.
If the PE is now at least then KE has been at the highest. It is also valid that KE is reduced as PE is increased as well as the maximum PE, the minimum KE.
Answer:
Explanation:
r = Radius = 2.7 cm
F = Force =
A = Area =
= Stress =
E = Young's modulus =
= Strain
= Original length = 67 cm
= Change in length
Young's modulus is given by
Strain is
Strain is given by
The cylinder height decreases by
