Answer:
The net force on the object is zero.
Explanation:
An object is moving with constant non-zero velocity. If velocity is constant, it means that the change in velocity is equal to 0. As a result, acceleration of the object is equal to 0. Net force is the product of mass and acceleration. Hence, the correct option is (d) "The net force on the object is zero".
Answer:
The direction of magnetic filed will be clockwise along y axis.
Explanation:
According to right hand rule,
Thumb of right hand shows the the direction of current and folded finger shows the direction of magnetic field.
So, a long and straight wire carrying a current and the direction of current is in the + y direction then the direction of magnetic filed will be clockwise across y axis.
Answer:
2.0 amps
Explanation:
Current is the ratio of voltage to resistance:
I = V/R = (3.0)/(1.5) = 2.0
The current in the wire is 2.0 amps.
