Answer:
2m/s
Explanation:
Total Distance = 300m+200m = 500m
Total Time = 100s+150s = 250s
Average Speed = Total distance travelled/Total time taken
=500m/250s
=2m/s
Answer:
The acceleration of the proton is 1.403 x 10⁹ m/s²
Explanation:
Given;
speed of proton, v = 7.7 m/s
magnitude of magnetic field, B = 1.9 T
Magnetic force of moving proton is given by;
F = qvBsinθ
Centripetal force on the moving proton is given by;
where;
q is charge of the proton = 1.602 x 10⁻¹⁹ C
m is mass of proton = 1.67 x 10⁻²⁷ kg
Therefore, the acceleration of the proton is 1.403 x 10⁹ m/s²
Answer:
All parts of a wheel rotating about a fixed axis must have the same angular speed.
All parts of a wheel rotating about a fixed axis must have the same angular acceleration.
Explanation:
In a rigid body in rotation (a rotating wheel) with respect to a fixed axis, each particle on the body turns around the same angle in a certain time interval, having the same angular speed and the same angular acceleration. Otherwise, the wheel will deform, therefore it would not be in equilibrium
Some of the objects might still sink/ float based on their density compared to the viscosity of the vegetable oil.
