Description of motion has to refer to the change in distance over a certain amount of time, or balanced forces
Answer:
The potential difference is 121.069 V
Solution:
As per the question:
Diameter of the cylinder, d = 9.0 cm = 0.09 m
Length of the cylinder, l = 40 cm = 1.4 m
Average Resistivity,
Current, I = 100 mA = 0.1 A
Now,
To calculate the potential difference between the hands:
Cross- sectional Area of the Cylinder, A =
Resistivity is given by:
Now, using Ohm's Law:
V = IR
Answer:
Work is equal to the change in kinetic energy.
Explanation:
Since energy cannot be created nor destroyed, and work is a form of energy, the work done by a force acting on an object must be equal to the kinetic energy gained by the object.
This is summarized by the work-energy theorem, which can be written as:
where
W is the work done on the object
m is the mass of the object
v is the final speed of the object
u is the initial speed of the object
An atoms nucleus splits into two smaller nuclei and generally one or more neutrons.
Scalar Quantity :-
→ These are the quantities with magnitude only . These quantities doesn't have to be mentioned with direction
eg.)=> Mass , Temprature .
Vector Quantity :-
→ These quantities are described with both Magnitude and Direction . These quantities follow special type of algebra called Vector algebra .
eg.)=> Force , Displacement
