Given equations:
Substitute 3 for y in equation (1);
Substitute 3 for y in equation (3);
Adding equation (4) and (5);
Substitute 2 for x in equation (4);
Therefore, the values of (x,y,z) is (2,3,2).

Answer:
Explanation:
Initially , crate is going upwards with uniform velocity so net force on crate is zero.
Tension T = mg ( its weight )
= 14.5 x 9.8
= 142.1 N
Now tension is increased to 180 N , so net force on it
= 180 - 142.1 = 37.9 N
Work done by tension that is 180 N
= Tension x displacement
= 180 x 1.15 x 10⁻³
= .207 J
A 520 Hz tone is sounded at the same time as a 516 Hz tone now the beat frequency is 4 Hz.
<h3>What is a frequency?</h3>
The pace of direction changes in current per second is known as frequency. It is expressed in hertz (Hz), a unit of measurement that is used internationally. One hertz is equal to one cycle per second. One hertz (Hz) is equivalent to one cycle per second. A complete alternating current or voltage wave is referred to as a cycle.
- f0=f2=f1 i the formula for frequency .
- then 520 Hz- 516 Hz= 4 HHz.
