Answer: a = 0.647 m/s^2
Explanation:
Acceleration = change in speed / time → a = 22 / 34 → a = .647 m/s^2
I am not sure of this, but it is either the third option or the last option.
Answer:
4.81x10³ Ω*m
Explanation:
The resistivity (ρ) of the skin can be calculated using the following equation:
<u>Where:</u>
<em>R: is the electrical resistance of the skin = 500x10³ Ω</em>
<em>A: is the cross-sectional area of the skin</em>
<em>l: is the length of the skin= 1.6 m</em>
Since we can model the body between the hands as a cylinder, the cross-sectional area is:
Now, we can fin the resistivity (ρ) of the skin:
Therefore, the resistivity of the skin is 4.81x10³ Ω*m
I hope it helps you!
Answer:
charge will be equal to
Explanation:
We have given mass of the particle m = 1.45 gram = 0.00145 kg
Acceleration due to gravity
Electric field E = 700 N/C
Electric force will be equal to , here q is charge and E is electric field
For particle to be stationary this force must be equal to force due to gravity , that is mg force
So qE = mg
So charge will be equal to
