Now none of these answers are really good a Table is best fit to show a wide range of data, while a graph is still used for the same purpose, its data is usually scattered, so a table is a neat and organized way to display a wide range of data.
Explanation:
If the turntable starts from rest and is set in motion with a constant angular acceleration α. Let is the angular velocity of the turntable. We know that the rate of change of angular velocity is called the angular acceleration of an object. Its formula is given by :
............(1)
Using second equation of kinematics as :
Using equation (1) in above equation
In one revolution, (in 2 revolutions)
Hence, this is the required solution.
Answer:
Explanation:
Normal length of spring = 28.3 cm
stretched length of spring = 38.2 cm
length of extension = 38.2 - 28.3 = 9.9 cm
= 9.9 x 10⁻² m
force applied to stretch = .55 x 9.8 ( mg )
= 5.39 N
Force constant = force applied / extension
= 5.39 / 9.9 x 10⁻²
= .5444 x 10² N /m
= 54.44 N/m
Answer:
-15.67287 N/C
Explanation:
= Location of electron =
= Location of electric field =
e = Charge of electron =
k = Coulomb constant =
Distance between the points is
Electric field is given by
The magnitude of the electric field is 15.67287 N/C
The direction is negative as the electron has negative charge.
