Which statement describes the relationship of voltage and current?
2 answers:
By definition, of the law of ohm, we have to:
Where,
V: voltage
I: current
R: resistance
Therefore, we have that the relationship between voltage and current is proportional.
The proportionality constant for this case is the resistance.
For the current we have:
The proportionality constant for this case is the inverse of the resistance.
Answer:
A statement that describes the relationship of voltage and current is:
Voltage is directly proportional to current because I = V / R

Answer: 2.13 × 10⁻⁷ N
Explanation:
Gravitational force exists between any two bodies having mass.
Force of gravity is given by:
It is given that, mass of newborn baby is M = 2.50 kg
Mass of the doctor, m = 80.0 kg
Distance between the two, r = 0.250 m
Gravitational constant, G = 6.67 × 10⁻¹¹ N m²/kg²
⇒F = (6.67 × 10⁻¹¹ N m²/kg² × 2.50 kg × 80.0 kg )÷ (0.250 m)² = 2.13 × 10⁻⁷ N
Thus, the force of gravity between new born baby and doctor is 2.13 × 10⁻⁷ N.
