Answer:
2,340,000 J
Explanation:
Work done can be described as when energy or force is applied to an object to cause displacement
Work done is measured in joules
1 Watt = 1 Joule / second
650 watts = 650 Joules / second
convert 650 joules to seconds by multiplying by 3600
650 x 3600 = 2,340,000 J
Answer:
The average gauge pressure inside the vein is 110270.58 Pa
Explanation:
This question can be solved using the Bernoulli's Equation. First, in order to determine the outlet pressure of the needle, we need to find the total pressure exerted by the atmosphere and the fluid.
Then, we have to find the fluid's outlet velocity with the transversal area of the needle, as follows:
As we have all the information, we can complete the Bernoulli's expression and solve to find the outlet pressure as follows:
Answer:
Car has more power output than crane
Explanation:
We have given that mass of the crane m = 1000 kg
Height through which crane lift the steel beam h = 10 m
Acceleration due to gravity
So work done by crane
Time period is given as t = 5 sec
We know that power
Now mass of the car = 1000 kg
Initial velocity u = 0 m /sec
Final velocity v = 10 m/sec
We know that work done is equal to the change in kinetic energy
So work done
Time ids given as t = 2 sec
So power
So car has more power output than crane
