Well Hmm how much you tell me it’s your work lol
Answer:
The product of mass times velocity for both objects is the same.
Explanation:
They both have the same velocity. False
They both have the same mass. False: Because two objects of different masses can have the same momentum. The least massive of the two objects will have the greatest kinetic energy.
The product of mass times velocity for both objects is the same. True: Same momentum means that the large mass must have a small velocity; therefore, their product is equal to the small mass times a large velocity.
Mass and velocity is the same for both. False: Based on what was stated for the second option.
Answer:
The correct answer would be downwards
Hope this helps have a good day
Kinetic energy is movement so A
Potential is still so false
Explanation:
Given that,
Diameter of the gold wire, d = 0.84 mm
Radius, r = 0.42 mm
Electric field in the wire, E = 0.49 V/m
(a) Electric current density is given by :
And electric field is :
is resistivity of Gold wire
So,
(b) The potential difference between two points in the wire is given by :
(c) Resistance of a wire is given by :
Hence, this is the required solution.
