2.5N
Explanation:
Given parameters:
Mass of object = 500g
Acceleration = 5m/s²
unknown:
Resultant force = ?
Solution:
According to Newton's second law "the net force on a body or the resultant force is the product of its mass and acceleration".
Resultant or net force = m x a
where m is the mass
a is the acceleration
Now we need to convert the mass to kg
1000g = 1kg
500g = = 0.5kg
Therefore;
Input the parameters:
Force = 0.5 x 5 = 2.5N

Yes. It means that the acceleration increases at a constant rate, for example 3 mph every second.
The answer should be B.

Answer:
Electric current can best be induced in a wire by moving a magnet up and down near the wire is the correct answer.
Explanation:
Electric current is the flow of electron that carries the negative charge in the electric circuit.
Electric current induced in the wire through:
- Electric current is induced in the wire when the magnet moves in and down of the wire that is connected to a very high resistance voltmeter and when we move the magnet up and down the magnetic flux gets change and these changes produce induced current
- When the coil of wire is put in the magnetic field which is changing then the current will be induced in the wire.
