Answer:
Momentum, p = 34.937 kg-m/s
Explanation:
It is given that,
Force acting on the bowling ball, F = 48.2 N
Velocity of bowling ball, v = 7.13 m/s
We have to find the momentum of the ball. Momentum is given by :
p = mv........(1)
Firstly, calculating the mass of bowling ball using second law of motion. The force acting on the ball is gravitational force and it is given by :
F = m g (a = g)
m = 4.9 kg
Now putting the value of m in equation (1) as :
p = 34.937 kg-m/s
Hence, this is the required solution.
When breathing out, it pushes your diaphragm, the muscle below your lungs, up, which then causes the air to leave your lungs.
Answer:
63
Explanation:
it would take around 63 if ur asking for 1200/19.1
Answer:
Explanation:
Compression
The region in a medium where the distance between the vibrating molecules is minimum is compression.
This is the region with higher air pressure than the surrounding .
Rarefaction
The region in a medium where the distance between the vibrating molecules is maximum is rarefaction.
This is the region with relatively low air pressure.
hope it helps :)
Hello.
The formula for Power is Work divided by Time; however, we do not have our value for Work - yet.
To find for the Work inputted, we need to use its formula: Force * Distance.
Let's multiply our Force by our Distance. Remember that our Force is always measured in Newtons (N), and our Distance is measured by Meters (M).
35,000 * 25 = 875,000 J (Unit for Work is "J" or "Joules")
Now that we have the value for Work, let's apply it to our Power formula.
P = 875,000 / 45; 19,444.44~
The Power required to lift the girder is 1944.44~ W (Unit for Power is "W" or "Watts").
I hope this helps!
