Answer:
c) current
Explanation:
Ohm's law states that the current I flowing through a conductor of resistance R is directly proportional to the voltage or potential difference V applied across its terminals provided that the temperature and other necessary conditions remain constant.
Mathematically this law can be written as follows;
When we make R the subject of formula from equation (1), we get the following;
Answer:
Positive velocity and negative acceleration
Explanation:
An object moving in the positive direction has a positive velocity.
An object that's slowing down while moving in the positive direction has a negative acceleration.
Answer:A)3074m,3074.37m/s
B)12905.4m,19100.54m/s
Explanation:the formula for electric field =V/d
Where V=velocity of the particle,d=distance covered from the electric field source
A)E=V/d
1.48=4.55×10^5/d
d=4.55×10^5/1.48=3074m
Distance of B from centre of the field=3074+0.370=3074.370m
B)d=V/E=1.91×10^4/1.48
d=12905.4m
At point B
Distance=12905.4+0.370=12905.770
V=Ed=12905.770×1.48=19100.54m/s
Answer:
Position.
Explanation:
Motion can be defined as a change in location with respect to a reference point.
This ultimately implies that, motion would occur as a result of a change in location (position) of an object with respect to a reference point or frame of reference i.e where it was standing before the effect of an external force.
Mathematically, the motion of an object is described in terms of acceleration, time, distance, speed, velocity, displacement etc.
A complete description of your position includes a distance, direction, and reference point. Thus, this includes an object's distance in a certain direction from a reference point.
The work-energy theorem states that the net work done by the forces on an object equals the change in its kinetic energy.
