Answer
given,
initially rotating speed = 130 rad/s
final rotating speed = 0 rad/s
constant acceleration = 3 rad/s²
a) using equation of rotating acceleration
3 t = 130
t = 43.33 s
time does the disk take to stop is equal to 43.33 s
b) again using equation of rotation
angle does the disk rotate during that time is equal to 2817 rad
The answer is; light waves, sound waves, and ocean waves.
Light waves come from the sun as electromagnetic transverse waves while the sound and oceans waves are mechanical waves. We interact with these very regulary in our lifetime. All these waves share the property of having frequencies, wavelengths and amplitudes.
Answer: 100 m/s^2
F=ma
Explanation:
50N = 50 kg*m/s^2
500g = 0.5 kg
F=ma
a = F/m
a = (50 kg*m/s^2)/(0.5 kg)
a = 100 m/s^2
Answer: The correct answer is "magnetic field".
Explanation:
A magnetic field is produced around the current carrying wire.
If you bring compass needle around the current carrying wire then it shows the deflection which indicates that there is a magnetic field around the current carrying wire.
Magnetic fields are the area around the surrounding of magnet in which magnetic force can be experienced.
Therefore, a magnetic field is produced around a wire when an electrical current is in the wire.
