Answer:a lid
Explanation bob pulled the lid off the jar of pickles
Given:
ρ = 1.18 kg/m³, density of air
v = 8 m/s, flow velocity
Q = 9 m³/s, volumetric flow rate
The minimum power required (at 100% efficiency) is
The actual power will be higher because 100% efficiency is not possible.
Answer: 339.8 W (nearest tenth)

Answers:</h2>
-The first direct detection of gravitational waves came in 2015
-The existence of gravitational waves is predicted by Einstein's general theory of relativity
-Gravitational waves carry energy away from their sources of emission
<h2>
Explanation:</h2>
Gravitational waves were discovered (theoretically) by Albert Einstein in 1916 and "observed" for the first time in direct form in 2015 (although the results were published in 2016).
These gravitational waves are fluctuations or disturbances of space-time produced by a massive accelerated body, modifying the distances and the dimensions of objects in an imperceptible way.
In this context, an excellent example is the system of two neutron stars that orbit high speeds, producing a deformation that propagates like a wave,<u> in the same way as when a stone is thrown into the water</u>. So, in this sense, gravitational waves carry energy away from their sources
.
Therefore, the correct options are D, E and F.
The momentum should be .5 because you multiply the mass and velocity to get momentum
<u>MOMENTUM IS CONSERVED</u> (law of Nature)
That means that momentum can move from one object to another object, but it's never created or destroyed. The amount of momentum AFTER something is the same as it was BEFORE.
<u></u>
<u>Before:</u>
(ball momentum = 12), (pin momentum = 0)
Ball + Pin = 12 unts
<u></u>
<u>After:</u>
Momentum is conserved.
Ball + Pin still has to be 12 units
Ball = 8 units
So Pin has to be the other <em>4 units</em>.
