It increases as the number of protons and electrons in the shell increases
Around 70-72% of earth’s surface is covered in water (most of it is salt water).
Hope this helps.
Answer:
b) se duplica
Explanation:
The disk is moving with constant angular velocity, let's call it
.
The linear velocity of a point on the disk is given by

where r is the distance of the point from the axis of rotation.
In this problem, the object is moved at a distance twice as far as the initial point, so

Therefore, the new linear velocity is

So, the velocity has doubled, and the correct answer is
b) se duplica
The electricity produced by a generator works through the concepts of the following three factors; magnetic field, voltage and current. When a conductor with current flowing in it is placed in a magnetic field, it will cause the electrons to move in a direction perpendicular to the magnetic field. When working with generators, the guide for this direction is Fleming's Right Hand Rule. Since the electron move in perpendicular motion with magnetic field all the time, it would cause it to spin in a helical direction. These turns would then induce voltage and create electricity.
Answer:
1.2 x 10¹¹ kgm²/s
Explanation:
m = mass of the airplane = 39043.01
r = altitude of the airplane = 9.2 km = 9.2 x 1000 m = 9200 m
v = speed of airplane = 335 m/s
L = Angular momentum of airplane
Angular momentum of airplane is given as
L = m v r
Inserting the values
L = (39043.01 ) (335) (9200)
L = (39043.01 ) (3082000)
L = 1.2 x 10¹¹ kgm²/s
