y(t) = 
Explanation:
Given data :
storage tank contains a liquid at depth ; Y
when tank is half full ; y = 0
flow rate = q
sinusoidal rate = 3Q 
Determine how the equation can be written for this system
solution is attached below
note ; from the question it can be seen that the surface area ( A ) is constant
Number of neutrons: atomic mass - atomic number
Element X's atomic mass is 79 and its atomic number is 39. Subtract 39 from 79 to find how many neutrons Element X has.
79 - 39 = 40
Element X has 40 neutrons.
Answer:
B. 1/6 m/s
Explanation:
Parameters given:
Mass of first glider, m = 1 kg
Initial speed of first glider, u = 1 m/s
Mass of second glider, M = 5 kg
Initial speed of second glider, U = 0 m/s.
Using the principle of conservation of momentum, we have that:
Total initial momentum = Total final momentum
=> m*u + M*U = m*v + M*V
Where v is the final velocity of the first glider and V is the final velocity of the second glider.
Since they stick upon collision, their final velocities are the same, hence, v = V
m*u + M*U = m*v + M*v
m*u + M*U = (m + M)*v
Also, since the second glider is initially at rest, U = 0
m*u = (m + M)*v
Therefore,
v = (m*u) / (m + M)
v = (1 * 1) / (1 + 5)
v = 1/6 m/s
Explanation:
Elements can be differentiated on the basis of their spectral lines. As the spectra of any element is obtained when the electrons in the orbits of an atom change their states. When they move from lower to higher orbits they absorbs the radiation or energy. When the fall back from higher energy state to lower state they emit the radiations. Thats how the spectra of radiation is obtained. Now coming towards your question, as the different elements have different atomic numbers, they have different number of electrons in their shells. That's why the presence of the number of electrons in the shells of different elements vary. So the different number of electrons in different elements lead to the production of different numbers of spectral lines.
Answer:
Explanation:
A )
The smallest tidal ranges are less than 1 m (3 feet). The highest tides, called spring tides, are formed when the earth, sun and moon are lined up in a row. This happens every two weeks during a new moon or full moon. Smaller tides, called neap tides, are formed when the earth, sun and moon form a right angle.
C ) The most extreme tidal range occurs during spring tides, when the gravitational forces of both the Moon and Sun are aligned (syzygy), reinforcing each other in the same direction (new moon) or in opposite directions (full moon).
