Torque of F1 = 30*0.025 = 0.75Nm anticlockwise
Torque of F2 = 34 * 0.020 = 0.68Nm clockwise
Horizontal component of F3:
cos 50 = x/20
x = 12.856 N
Torque of F3 horizontal component = 12.856 * 0.01 = 0.129Nm anticlockwise
0.129 + 0.75 - 0.68 = 0.199Nm anticlockwise
sorry I'm not sure is it correct
Answer:
5.1 meters
Explanation:
Terra tosses a 0.20kg volleyball up at at a speed of 10 m/s
The height can be calculated as follows
= v^2/2g
= 10^2/2×9.8
= 100/19.6
= 5.1 meters
Hence the height is 5.1 meters

fault. Normal (extensional ) fault is a
displacement of a rock as a result of rock-mass movement and occurs when the
crust is stretching. Because of the stretching the thickness of the crust is
reduced and the crust or horizontally extended. </span>
That's true.
I have a hunch that there definitely IS a change of phase at every reflection.
Wave speed = frequency * wavelength
Wave speed = 4 * 25
Wave speed = 100 m/s
