Wave speed = (wavelength) x (frequency)
= (1.5 m) x (500 / sec)
= 750 m/s .
I think the correct answer from the choices listed above is option A. The correct arrangement of the substances according to the <span>most to the least ordered particle arrangement should be wood, water and neon gas. Wood should be the first since it is solid which has the most ordered structure as compared to the liquid and a gas. The neon gas is the last since as a gas it has the least ordered structure.</span>
<span>
They are negative, and they repel.
The left is negative and the right is positive, so they attract. </span>
Answer:
The kinetic energy when the film vault landed is 12744000J.
Explanation:
The kinetic energy is defined as:
(1)
Where m is the mass and v is the velocity.
By means of equation 1, the kinetic energy of the film vault when it landed can be determined
But
Hence, the kinetic energy when the film vault landed is 12744000J.
Fnet=Fapp
manet=Fapp
Solve for m
m=Fapp/anet
m=100N/4m/s^2
so mass must equal 25kg
Assuming this is a frictionless surface
