Answer:
Magnetism is a physical phenomenon that manifests itself in a force acting between magnets or other magnetized or magnetisable objects, and a force acting on moving electric charges, such as in current-carrying cables. The force action takes place by means of a magnetic field, which is generated by the objects themselves or otherwise. There are natural and artificial magnets. All magnets have two poles called the north pole and the south pole. The north pole of one magnet repels the north pole of another magnet and attracts the south pole of another magnet; the same with south poles.
Answer:
the impulse experienced by this object is 4 Ns
Explanation:
Given;
mass of the object, m = 3 kg
velocity of the object, v = 4 m/s
resistive force, F = 20 N
duration of impact, t = 0.2 s
The impulse experienced by this object is calculated as follows;
J = F x t
J = 20 x 0.2
J = 4 Ns
Therefore, the impulse experienced by this object is 4 Ns
Answer:
Election manipulation, vote rigging
Explanation:
Electoral fraud is sometimes known as election fraud or election manipulation or vote rigging is illegal in the process of election.
The electoral fraud changes from country to country .
The election process is conducted and supervised by the electoral bodies.
The manipulation of electoral processes and outcomes are also referred to as electoral malpractice.
In India a huge number of electoral malpractices are occurs.
It will happen by elections or candidates with strong criminal background are fighting the elections.
a) starting position of this object is 3m
b) Velocity is 3m/s
Explanation:
The points identified on the blue line are; (0,3) and (4,15)
The starting position of this object is at 3m where time was 0 seconds.
The velocity of this travelling object is calculated by finding the slope of the graph.
slope=velocity=Δy/Δx
Δy=15-3=12
Δx=4-0=4
m=12/4=3
velocity is 3 m/s
