When object travels with uniform velocity, no force acts on it. hence , yes.
Answer:
True
Explanation:
Assuming no wind resistance, there will be no horizontal acceleration, because there will be no forces acting on it.
Can we see the diagram? Thanks.
Answer:
Centripetal acceleration of the car is (4.96 g) m/s²
Explanation:
It is given that,
Radius of circle, r = 95 m
Speed of the car, v = 68 m/s
We need to find the centripetal acceleration. It is given by :
So,
Since, g = 9.8 m/s²
So,
So, the magnitude of the centripetal acceleration is (4.96 g) m/s². Hence, this is the required solution.
Answer:
Force = 0.1N
Explanation:
Magnetic force, attraction or repulsion that arises between electrically charged particles because of their motion. ... The magnetic force between two moving charges may be described as the effect exerted upon either charge by a magnetic field created by the other.
Magnitude of the force is given by ILB SIN90 = ILB
where I is current.
L = lenth
B= magnetic component (Tesla)
Force = 10 * 2/100 * 0.5
Force = 0.1N.
