What is the net force acting on a golf car travelling at constant speed of 5 mph

1 answer:

6 0

The answer is 0 Newtons

This is because of a key word in the question: “constant”

When we say something has a constant speed, that means that its acceleration is 0.

Using the equation derived for Newton’s 2nd law, we see that F=ma

Force = mass x acceleration

If acceleration, a, equals 0, then when we multiply our mass times acceleration 0

F=m(0)

Anything times zero equals zero

So, F=0

A red sports drink contains Red 40 dye. A 5.4 mL aliquot of this sports drink was diluted to 25.0 mL with deionized water in a v

miskamm [114]

Answer:

84.0 ppm is the concentration of Red 40 dy in the original sports drink.

Explanation:

Concentration of red dye in sport drink before dilution $C_1=?$

Volume of the sport drink before dilution $V_1=5.4 mL$

Concentration of red dye in sport drink after dilution $C_2=18.1 ppm$

Volume of the sport drink after dilution $V_2=25.0 mL$

$C_1V_1=C_2V_2$ ( dilution )

$C_1=\frac{C_2V_2}{V_1}=\frac{18.1 ppm\times 25.0 mL}{5.4 mL}$

$C_1=83.80 ppm\approx 84.0ppm$

84.0 ppm is the concentration of Red 40 dy in the original sports drink.

The mass of an atom of element x is equivalent to the total mass of 7 hydrogen atoms

Bond [772]

Answer: I'm not sure what your question is but i'll answer as best as I can.

Explanation:

Since X is equal to 7 H and we know that H is equal to 1.008, we can just do 7x1.008 = 7.056 g. I hope i helped and please clarify more in the future.
