The fatal current is 51 mA = 0.051 Ampere.
The resistance is 2,050Ω .
Voltage = (current) x (resistance)
= (0.051 Ampere) x (2,050 Ω) = 104.6 volts .
==================
This is what the arithmetic says IF the information in the question
is correct.
I don't know how true this is, and I certainly don't plan to test it,
but I have read that a current as small as 15 mA through the
heart can be fatal, not 51 mA .
If 15 mA can do it, and the sweaty electrician's resistance is
really 2,050 Ω, then the fatal voltage could be as little as 31 volts !
The voltage at the wall-outlets in your house is 120 volts in the USA !
THAT's why you don't want to stick paper clips or a screwdriver into
outlets, and why you want to cover unused outlets with plastic plugs
if there are babies crawling around.
Answer:
F = 789 Newton
Explanation:
Given that,
Speed of the car, v = 10 m/s
Radius of circular path, r = 30 m
Mass of the passenger, m = 60 kg
To find :
The normal force exerted by the seat of the car when the it is at the bottom of the depression.
Solution,
Normal force acting on the car at the bottom of the depression is the sum of centripetal force and its weight.
N = 788.6 Newton
N = 789 Newton
So, the normal force exerted by the seat of the car is 789 Newton.

Answer:
C. Photosynthesis
Explanation:
The redox reaction given in this question is given as follows:
6H2O + 6CO2 → C6H12O6 + 6O2
In this reaction, water (H2O) reacts with carbon dioxide (CO2) to form glucose (C6H12O6) and oxygen (O2). This is the general equation for PHOTOSYNTHESIS process, which is the process whereby plants manufacture their food (sugar) by combining water and carbon dioxide.
In the equation above, water is oxidized into oxygen, while carbon dioxide is reduced into glucose. This makes it an oxidation-reduction (redox) reaction.
