Assuming 100% efficient energy conversion, how much water stored behind a 50cm high hydroelectric dam would be required to charg
7nadin3 [17]

Answer:

12.245m3

Explanation:

The electric energy is created by The potential energy substended by the specific volume of water in dam.

Electric energy is calculated as

E= Q× V

E is Energy, Q is charge and V is Voltage

Note that this energy has been given and is 60Joules

From conservation of energy it means;

M× g×h = 60

Where M is the mass of water.

g is acceleration of free fall due to gravity which is 9.8m/S2

h is the height of water flow.

From change of subject of formula for M; we have:

M = 60/ g × h

= 60/ 9.8 × 0.5

= 12.245kg

Now how much water required means the volume of water;

Note density = mass/volume

Therefore volume = mass/density

=12.245/1= 12.245m3

Note the density of water is 1kg/m3

1-D catch-up: Two cars move with constant velocities. At t = 0, a blue car is at xBo = 20 m. After t = 4s in the blue car time f
OlgaM077 [116]

Answer:

5.71 m/s ;

20 m/s

Explanation:

Blue car:

At time, t = 0 ; Initial position = 20 m

Final position, = 60m after 4 seconds

The velocity = change in distance / change in time.

Velocity of blue = (60 - 20)m ÷ ((4 + 3) - 0),

Velocity of blue car = 40 / 7

= 5.71 m/s

Red car:

Initial Position = 0 ; final Position = 60

Time taken = 3 seconds

Velocity of Red car = (60 - 0)m ÷ 3

Velocity of Red car = 60 / 3

= 20 m/s
