Answer:

This happens because of inertia.

Explanation:

Inertia is the ability of a body to remain in its state of rest or relative movement, while an external force is not acting on it.

It is when a body objects to modifying its state of relative rest or movement, including the speed and direction in which this happens.

When a car accelerates, a cup of coffee sitting in a cup-holder spills out onto the rear seats, because it has left its state of rest due to the acceleration force of the car.

Answer:

See the explanation below

Explanation:

This happens because the coffee was at rest, at the time when the car accelerates to move forward the container containing the coffee also accelerates in the same direction, the liquid when moving suddenly spills. The same will happen if the car slows down, any sudden movement changes will cause the coffee to spill, understood by sudden movements when it accelerates or slows down.

How many grams does 15.58 L of gasoline weigh? Gasoline has a density of 0.74 g/mL

Korolek [52]

We are given volume of gasoline = 15.58 L and

Density = 0.74 g/mL.

Density is given in grams(g) per milliliter (mL). So, we need to convert given volume in mL also.

We know, 1 litre = 1000 milliliters

Therefore, 15.58 L = 15.58 * 1000 mL = 15580 mL

We could rewrite,

Volume of gasoline = 15580 mL.

Formula for density is..

Density (ρ)= $\frac{Mass}{ Volume}$

Plugging values in formula,

0.74 g/mL = $\frac{Mass}{15580 \ mL}$

Muliplying both sides by 15580.

$0.74 g/mL * 15580mL =\frac{Mass}{15580 \ mL} * 15580mL$

11529.2g = mass.

Therefore, 11529.2g grams does 15.58 L of gasoline weigh.

How does the temperature of water affect the speed of the sound waves?

nikitadnepr [17]

Answer:

Temperature is also a condition that affects the speed of sound. Heat, like sound, is a form of kinetic energy. Molecules at higher temperatures have more energy, thus they can vibrate faster. Since the molecules vibrate faster, sound waves can travel more quickly.

An capacitor consists of two large parallel plates of area A separated by a very small distance d. This capacitor is connected t

scoundrel [369]

Answer:

Will be doubled.

Explanation:

For a capacitor of parallel plates of area A, separated by a distance d, such that the charges in the plates are Q and -Q, the capacitance is written as:

$C = \frac{Q}{V} = e_0\frac{A}{d}$
