Ohm's law states that the voltage within an electrical circuit is equal to the product of the current and the voltage. Mathematically it is written as V=IR where V is the voltage, I is the current and R is the resistance. If a circuit has a voltage of 9.0 Volts and a resistance of 36.0 Ohms, the current is I = V / R = 9.0/36.0 = 0.25 Amps.
Option C homie. 0.00001 C at 2 meters is 0.225 N
Answer:
Explanation:
mass of each object = m
momentum conservation: mv₁ + mv₂ = 2mv, so v = (v₁ + v₂)/2
Initial KE = mv₁²/2 + mv₂²/2 = m(v₁² + v₂²)/2
final KE = (2m)v²/2 = m(v₁ + v₂)²/4
Change in KE = m(v₁² + v₂²)/2 - m(v₁ + v₂)²/4 = m(v₁ + v₂)²/4
= m(v₁² + v₂² + 2v₁v₂)/4 = (1/2) m(v₁² + v₂²)/2 + mv₁v₂/2
Fraction loss = change in KE / initial KE = 1/2 + v₁v₂/(v₁² + v₂²)
Answer:
Explanation:
we know that acceleration =Δv/t
Δv=vf-vi
Δv=1.0-5.5=-4.5
now
a=-4.5/3.0
a= -1.5m/s²
The heat from inside the jacket transfers heat to her body also known as conduction.
