<em>Hello, </em>
<h3><u>QUESTION)</u></h3>
<em>✔ We have: T = 1/f; with T in s, and f in Hz </em>
- T = 1/5,0 x 10² Hz
- T = 2,0 x 10⁻³ s
The period of the microwave is therefore 2 ms.
Long wavelengths and low frequencies.
Answer:
Equivalent Resistance of Resistors in Parallel is
1/R = 1/r1 + 1/r2 .....
1/R = 1/7 + 1/7 + 1/7
R= 7/3
R=2.33ohms
Positive acceleration is a parabola pointing upwards.
Negative acceleration is a parabola pointing downwards.
I am not sure what you mean by the balanced forces. But I guess it means no acceleration which is a straight line. It can be a horizontal line or an inclined line.
<u>Answer:</u>
<u>Explanation:</u>
Given data,
- mass of the crate, m = 200 kg
- height of the shipping container, h = 45 m
- gravitational of a body is possessed by the body due to the virtue of its position.
The formula for gravitational potential energy is,
P.E = mgh joules
Substituting the values
P.E = 200 x 9.8 x 45
= 88,200 J
Hence, the <u>gravitational potential energy</u> of the crate <u>is, P.E = 88,200 J</u>
