Answer:
c. Both forces have equal magnitudes.
Explanation:
According to Newton´s 3rd Law, the force exerted by a body on another one , is equal and opposite to the one that the second object exerts on the first one.
This does not depend on the masses of the objects, so it doesn´t matter that m₁ be greater than m₂.
As examples of this, we can mention the gravity force, the electrostatic force, the normal force, etc.
So, in this case, taking into account only the magnitudes, we can say:
F₁₂ = F₂₁
Answer:
A. put water in a container under the pot water will disappear from the container .
Answer:
Magnetic field at given point is along + x direction
Explanation:
As we know that position of the wire is along Y axis
current is flowing along +y direction
so here we will have
now the direction of length vector is along +Y direction
also the position vector is given as
now for the direction of magnetic field we can say
so magnetic field is along +X direction
Explanation:
When a body has an electric charge, it generates an electric field around it, if we introduce an electric charge into this field, it will be affected by the first one. Experiencing a greater force the closer a charge is to the other, that is, depends on the position within the electric field. This force is conservative, so it can be found from the negative derivative of a scalar field, this field is the electric potential energy. Therefore, if the charges are of the same sign, the force will be repulsive (-) and the potential energy will be positive. If the charges are different, the force will be attractive (+) and the potential energy will be negative.
8 miles per hour
because if it is moving at 4 miles every half hour that means you have to multiply it by two to get it in miles per hour and we all know that 4 times 2 is 8 so it would be 8 miles per hour =)
