Answer:
his movement is proportional to the intensity of the earthquake,
Explanation:
An earthquake is a record of the intensity of an earthquake as a function of time.
Where the intensity is plotted on the y-axis, which corresponds to the vertical movement of the detector, this movement is proportional to the intensity of the earthquake, therefore the intensity increases the amplitude of the oscillation increases.
And the in x corresponds to time
Answer:
the sun is larger in mass and therefore gravitational pull.
Explanation:
Fun fact the moon has more gravitational force on the earth than the sun because its closer to the earth.
Answer:
The magnitude of the net current = 18 A.
Direction of the net current is along the negative z axis.
Explanation:
<u><em></em></u>
<u><em>Given:</em></u>
- Number of electrons flow through the given cross section,
- Number of electrons flow through the given cross section,
- Time interval for which the electrons and protons flow,
The current through a cross section is defined as the amount of charge passing through that cross section in unit time.
We know,
Charge on an electron,
Charge on a proton,
Therefore,
The amount of charge flowing due to electrons is given by
The amount of charge flowing due to protons is given by
The current flowing through the cross section because of the electrons is given as:
The negative sign shows that the current is due to the flow of negative charge, and the direction of current is always opposite to that of flow of negative charge i.e., electrons.
Thus, the direction of this current is along the negative z direction.
The magnitude of this current = 12 A.
The current flowing through the cross section because of the protons is given as:
The direction of this current is same as that of electrons,
The directions of the currents due to both, the electrons and the protons are along the negative z direction, therefore the magnitude of the net current is given as:
Answer:
Raising the highest point of the track to a higher point
Explanation:
When the rubber ball starts its motion, from the highest point of the track, it has only gravitational potential energy, given by:
where m is the mass of the ball, g is the gravitational acceleration and h is the height above the ground.
As the ball descends the track, this potential energy is partially converted into kinetic energy, given by:
(where m is the mass and v is the speed)
and partially lost as heat, due to the friction between the surface of the track.
As a consequence, the higher the initial height of the track (h in the formula), the greater will be the kinetic energy gained by the ball. A greater kinetic energy means a larger velocity, which also means that the ball will cover a longer distance before stopping.
