Answer:
Force, 
Explanation:
Given that,
A potential energy function for a system in which a two-dimensional force acts is of the form of :
We need to find the force that acts at the point (x, y). The force in 2 dimensional with components is given by :
So, the force acting at the point (x,y) is 
. Hence, this is the required solution.
The difference is (80 dB - 40 dB) = 40 dB.
The sound is 40 dB louder outside.
Each 10 dB means 10 times more sound power.
40 dB louder means 10x10x10x10 times more sound power.
That's <em>10,000 times</em> more sound power outside than inside.
Answer:
<h2>24 kg m/s</h2>
Explanation:
The momentum of an object can be found by using the formula
momentum = mass × velocity
From the question we have
momentum = 6 × 4
We have the final answer as
<h3>24 kg m/s</h3>
