Answer:The correct option is D (charge)
Explanation:
Car batteries are often rated in ampere-hours. And this information designate the amount of charge the battery can supply. To prove the above statement, ampere is the international system of Units (SI) for electric current. It represents a flow of one coulomb of electrical charge across a surface per second (C/s). Therefore, if One coulomb is equal to one second then one hour( 60x60) = 3600 C.
A Car battery is are designed in such a way to supply automobiles electrical charges through electrochemical means. It is an example of a wet cell battery filled with an electrolyte called sulfuric acid solution.
Answer:
5.25 m
Explanation:
Given;
The height equation h;
h=-x^2+3x+3
Where;
h = the height above water
x = horizontal distance from the end of the board
The maximum height is at h' = 0, when change in h with respect to change in x is equal to zero.
differentiating the equation h.
dh/dx = h' = -2x + 3 = 0
Solving for x;
2x = 3
x = 3/2
Substituting into the function h;
h max = -x^2+3x+3
h max = -(3/2)^2 + 3(3/2) +3 = -9/4 +9/2 +3 = 9/4 + 3 =
h max = 21/4 = 5.25 m
The x-component of the normal force is equal to <u>1706.45 N.</u>
Why?
To solve the problem, and since there is no additional information, we can safely assume that the x-axis is parallalel to the hill surface and the y-axis is perpendicular to the x-axis. Knowing that, we can calculate the components of the normal force (or weight for this case), using the following formulas:

Now, using the given information, we have:

Calculating, we have:


Hence, we have that the x-component of the normal force is equal to <u>1706.45 N.</u>
Have a nice day!
W = m g weight of drop
W = q E
m = q E / g = = 3 e E / g
m = 3 * 1.6E-19 * 1.4E4 / 9.8 = 6.96E-16 kg
