Answer:

Buttery popcorn contained in a large 1 liter bowl has a mass of about 50 grams of fat and about 650 calories

Explanation:

The question is about using correct units. The capacity of a bowl must be measured in a volume unit; the options were milliliter and liter. 1 milliliter is a very small amount (about 0.002 pint), so 1 liter is the correct option.

For the second blank, the options (mass units) are: microgram, milligram, gram, kilogram. Milligram is used to measure the mass of minerals, microgram is even smaller than milligram, the buttered popcorn weights much less than 50 kilograms. So, the correct option is 50 grams.

Answer:

Buttery popcorn contained in a large 1 liter bowl has a mass of about 50 mg and about 650 calories.

Explanation:

Liter is the most appropriate unit to measure a bowl. Usually 1 liter of liquid has a mass of 1000 gram. Since popcorn is something lightweight and only a few can fill the bowl quickly so 50 mg makes perfect sense with 1 liter of bowl and 650 calories in buttery popcorn.

If an atom has twelve electrons, how many electrons are in the n=1 energy level? how many electrons are in the n=2 energy level?

Sav [38]

The shells correspond with the principal quantum numbers (n = 1, 2, 3, 4 ...) Each shell can contain only a fixed number of electrons. The first shell can hold up to two electrons, the second shell can hold up to eight electrons, the third shell can hold up to 18 and so on.

A man pushed a cabinet with a force of 200N. What is the mass of the cabinet that accelerates 4 m/s/s?

ELEN [110]

Answer:

$\boxed {\boxed {\sf 50 \ kg}}$

Explanation:

We are asked to find the mass of a cabinet, given the force and acceleration. According to Newton's Second Law of Motion, force is the product of mass and acceleration. The formula for this is:

$F= m \times a$

The force is 200 Newtons, but we should convert the units to make unit cancellation easier. 1 Newton is equal to 1 kilogram meter per second squared, so the force of 200 Newtons is 200 kilogram meters per second squared.

The mass is unknown and the acceleration is 4 meters per second per second or 4 meters per second squared.

F= 200 kg*m/s²
a= 4 m/s²

Substitute the values into the formula.

$200 \ kg *m/s^2 = m \times 4 \ m/s^2$

We are solving for the mass, m, so we must isolate the variable. It is being multiplied by 4 meters per second squared. The inverse operation of multiplication is division. Divide both sides by 4 m/s²

$\frac {200 \ kg *m/s^2}{4 \ m/s^2}= \frac{m \times 4\ m/s^2}{4 \ m/s^2}$
