Explanation:
Momentum = mass × velocity
p = mv
p = (1000 kg) (14 m/s)
p = 14000 kg m/s
Answer:
south
cross sectional area of the beam
Explanation:
v = Velocity of ions = 
Number of ions per 
= 
Charge density would be the product of number of ions per 
and the charge of electrons multiplied by 2 as they are doubly charged.
Current density is given by
The current density is
The direction of the current density is opposite to the movement of the charged particle. The particles are moving north so the direction of current density will be to the south.
Current is given by
where A is the cross sectional area of the beam .
So the cross sectional area of the beam is required to determine the total current in this ion beam.
Answer:
Potential
Explanation:
This is because it has not yet fallen, and it has the potential to fall and turn into kinetic energy. When it starts falling, it will be kinetic.
Answer:
When there is an increase in the frequency of sound waves, the wavelength decreases.
Explanation:
Given data,
The frequency of the whale changes from 200 Hz to 300 Hz
The formula for frequency and wavelength is,
λ = v/f
Where v is the velocity of the sound waves in water (1531 m/s)
The wavelength at 200 Hz is,
λ = 1531/200
= 7.655 m
The wavelength at 300 Hz is,
λ = 1531/300
= 5.1 m
Hence, when there is an increase in the frequency of sound waves, the wavelength decreases.
Explanation:
Its because of the sunlight being much hoter than your body absorbs the heat of the sun.
And its also because of aerobic respiration in which your body takes in oxygen and digests gluecose to creates energy(beacuse of any physical activity like, playing and stuff). So during the proscess in which uour body creates energy(energy-andenoisine triphosphate) HEAT is also created
Thus, your body fells hot during playing and in sunlight
Hope it helps
Also see my comment pls theres another answer.
