Answer:
The dog has more momentum than the pony.
Explanation:
To solve this problem, we must remember the formula for calculating momentum, which is given below:
momentum = p = m*v
where m represents the mass of the object and v represents the velocity of the object
Using this knowledge, let's calculate the momentum for the dog and the pony.
Dog: p = m*v = (2kg)*(41 m/s) = 82 kg*m/s
Pony: p = m*v = (75kg)*(1 m/s) = 75 kg*m/s
Since 82 > 75, we can conclude that the dog has more momentum.
Hope this helps!
Answer:
This is because it is derived from newtons and metres as shown in the expression;
Explanation:
Answer:
The object will not move.
Explanation:
An object's motion can be changed by unbalanced forces. Balanced forces do not change the motion of an object. The motion of an object will not change if the forces pushing or pulling the object are balanced. An object that is sitting still will stay still if the forces acting on it are balanced.
When a 2 m long wire carrying 2 A of current pointing to the right is placed in a magnetic field of 4 T directed away from you then the force on the wire point down, therefore the correct option is D
<h3>What is a magnetic field?</h3>
A magnetic field could be understood as an area around a magnet, magnetic material, or an electric charge in which magnetic force is exerted.
According to Fleming's left-hand rule, A force perpendicular to the field and the direction of the current flow is experienced by a current-carrying conductor when it is placed in an external magnetic field.
Thus, The correct answer is D because the force on a 2 m long wire carrying 2 A of current pointing to the right when placed in a magnetic field of 4 T directed away from you causes the wire to point downward.
