Answer:b
Explanation:
We know power delivered by Pump is
where 
=Density of fluid
=Flow rate
=acceleration due to gravity
=Change in Elevation
If is increased by 4 time then
So power increases by four times.
Answer
1056
Explanation:
for example
A soil is to be excavated from a borrow pit which has a density of 1.75g/cc and water content of 12%. The G is 2.7 the soil is compacted to that water content of 18% and dry density of 1.65g/cc. for 1000 m3 of soil used in fill estimate
Quantity of soil to be excavated from pit in m3
Answer:
The force induced on the aircraft is 2.60 N
Solution:
As per the question:
Power transmitted, 
Now, the force, F is given by:
(1)
where
v = velocity
Now,
For a geo-stationary satellite, the centripetal force, 
is provided by the gravitational force, 
:
Thus from the above, velocity comes out to be:
where
R = 
R = 
where
G = Gravitational constant
T = Time period of rotation of Earth
R is calculated as 42166 km
Now, from eqn (1):
F = 2.60 N
Answer:You are correct, no need to change.
Explanation:
Answer:
Combination circuit; The basic strategy for the analysis of combination circuits involves using the meaning of equivalent resistance for parallel branches to transform the combination circuit into a series circuit.
Example:
The use of both series and parallel connections within the same circuit. In this case, light bulbs A and B are connected by parallel connections and light bulbs C and D are connected by series connections. This is an example of a combination circuit.
