C. Radiation Hope this helps and You're welcome. :3
Answer:
-5 meters
Explanation:
x = 3t² + 2t − 5
The initial displacement is when t = 0.
x = 3(0)² + 2(0) − 5
x = -5
Answer:
-25 rad/s²
29 times
3.8 seconds
50.54 m
26.6 m/s
Explanation:
= Final angular velocity
= Initial angular velocity
= Angular acceleration
= Angle of rotation
a = Acceleration = -7 m/s² (negative because of deceleration)
r = Radius of wheel = 0.28 m
Angular acceleration is given by
Angular acceleration of the wheel is -25 rad/s²
It took 3.8 seconds for the car to stop
The wheel rotated 29 times.
The
Initial velocity
The car’s initial velocity is 26.6 m/s
Distance covered in the time is 50.54 m
If the distance is found in meters we get 50.54 m which is very low. Considering the initial velocity is 95.76 km/h. Coming to a stop in that distance is very low. So, the values do not seem reasonable. At least a 100 m is required to stop from that speed.
A longitudinal wave is a wave that vibrates the medium in the same direction in which the wave energy travels.
The answer would be C.
