Resistance is equal to relation between voltage and current.

If we express current:

If current is in fact 0 then one of the quantities either voltage or resistance must be equal to zero. Since resistance cannot be equal 0, because that would violate mathematical law that states that division by zero is undefined the only logical conclusion is voltage.
So the answer should be C voltage and B zero.
Hope this helps!
<u>Given;</u>
mass m = 75 kg
acceleration a = 24.5 ms²
<em>F = ma </em>
F = 75 kg * 24.5 ms²
= 1837.5 kg ms².
Conduction. Because they are connected as they tranfer energy
Answer:
Tension of the wire(T) = 169 N
Explanation:
Given:
f = 65Hz
Length of the piano wire (L) = 2 m
Mass density = 5.0 g/m² = 0.005 kg/m²
Find:
Tension of the wire(T)
Computation:
f = v / λ
65 = v / 2L
65 = v /(2)(2)
v = 260 m/s
T = v² (m/l)
T = (260)²(0.005/2)
T = 169 N
Tension of the wire(T) = 169 N
Toy car will take the least amount of force.
this is because the toy car has a much lighter mad than the other objects meaning it will take less force to get it to move.
