Answer:
8.4 m/s
Explanation:
The toy completes 10 circle in 30 seconds. So its frequency of revolution is

The periof of revolution is the reciprocal of the frequency, so

The radius of the circular path is
r = 4.0 m
So the total distance covered by the toy in one circle is the length of the circumference:

And so the average speed is

Answer:
surface charge density on each sphere is
C
Explanation:
given data
radius of smaller sphere = 5 cm
radius of larger sphere is 12 cm
electric field at surface of larger sphere = 660 kV/m = 660 × 1000 v/m
solution
we apply here electric field formula that is express as
E =
.................1
put here value
660000 =
Q1 = 1056 ×
and
here field inside a conductor is zero so that electric potential ( V ) is constant
..................2
so Q2 will be
Q2 =
Q2 =
C
The kinetic theory of gases is a simple, historically significant model of the thermodynamic behavior of gases, with which many principal concepts of thermodynamics were established. The model describes a gas as a large number of identical submicroscopic particles, all of which are in constant, rapid, random motion
Answer:
A body having uniform velocity has zero acceleration because
there is not change in velocity.
