Answer:
V for dry skin = 41.83 volts
V for wet skin = 0.196 volts
Explanation:
The relationship between current and voltage is given as follows by Ohm's Law:
V = IR
where,
V = voltage
I = Current
R = Resistance
FOR DRY SKIN:
V = Vd = ?
I = 89 μA = 89 x 10⁻⁶ A
R = 4.7 x 10⁵ Ω
Therefore,
Vd = (89 x 10⁻⁶ A)(4.7 x 10⁵ Ω)
<u>Vd = 41.83 volts</u>
FOR WET SKIN:
V = Vw = ?
I = 89 μA = 89 x 10⁻⁶ A
R = 2200 Ω
Therefore,
Vd = (89 x 10⁻⁶ A)(2200 Ω)
<u>Vd = 0.196 volts</u>
Answer:
160 m/s
Explanation:
The Ferrari is moving by uniformly accelerated motion, with constant acceleration of a = 50 m/s^2, and initial velocity u = 10 m/s. The velocity at time t of the car is given by
where
u = 10 m/s
a = 50 m/s^2
If we substitute t = 3 s into the equation, we can find the velocity of the car after 3 seconds:
To accelerate a 34.01 kg-car at 0.55 m/s², a force of 19 N will be required, according to Newton's Second Law of Motion.
<h3>What does Newton's Second Law of Motion state?</h3>
Newton's Second Law of Motion states that acceleration (a) happens when a force (F) acts on a mass (m).
We want a car of mass 34.01 kg to have an acceleration of 0.55 m/s². We can calculate the required force using Newton's Second Law of Motion.
F = m × a = 34.01 kg × 0.55 m/s² = 19 N
To accelerate a 34.01 kg-car at 0.55 m/s², a force of 19 N will be required, according to Newton's Second Law of Motion.
