Listen in all of your classes and write down notes on EVERYTHING even if it may not seem important it will be useful in the future! :)
Answer:
"humans cannot hear all the same sound frequencies as animals", & "Humans cannot make make all the same sound frequencies as animals" are correct. the other two are incorrect, hope this helps!
I know that E.) Tension Force is one of them and B.) Gravity Force but I'm not sure about the others.
Answer:

Given:
Resistance (R) = 100 Ω
Current (I) = 5 A
Time (t) = 2 hours
To Find:
Heat developed (H) in the electric iron
Explanation:
Formula:

Substituting values of I, R & t in the equation:


Heat developed (H) in the electric iron = 15 kWh
The electric potential between the two charges is 91.68 V.
<h3>
Electric potential between the two charges</h3>
The electric potential between the two charges is calculated as follows;
V = Ed
where;
- V is electric potential
- E is electric field
- d is the distance of the charge
Substitute the given parameters and solve for electric potential,
V = 573 N/c x 0.16 m
V = 91.68 V
Thus, the electric potential between the two charges is 91.68 V.
