Answer:
Distance traveled in 1 liter = 40 km
Explanation:
Distance traveled = Energy / Opposing force = 40 x 10^6 J / 1000 N = 40000 m or 40 km
So, the car will moves to a distance of 40 km per liter under the opposing force of 1000 N…
Answer:
The magnetic force will be 0.256 N in +y direction.
Explanation:
It is given that, a wire along the z axis carries a current of 6.4 A in the z direction. Length of the wire is 8 cm. It is placed in uniform magnetic field with magnitude 0.50 T in the x direction.
The magnetic force in terms of length of wire is given by :

For direction,

So, the magnetic force will be 0.256 N in +y direction.
3 Newtons toward the right because Newton’s second law:
F = ma
15N - 12N = ma
3N = ma
(With the right being the positive direction and the left the negative direction)
Hello,
The answer is option B KE=1/2mv^2.
Reason:
In order to calculate the kinetic energy of a object you need to use option B which is the correct formula to find the kinetic energy.
