Answer:

D = 4 g/cm³

Explanation:

Density = Mass / Volume

Step 1: Define

D = x

M = 12 g

V = 3 cm³

Step 2: Substitute

D = 12g/3 cm³

Step 3: Simplify

A 12-V battery maintains an electric potential difference between two parallel metal plates separated by 10 cm. What is the elec

Sauron [17]

Answer:

The electric field between the plates is 120 V/m.

(c) is correct option.

Explanation:

Given that,

Potential difference = 12 volt

Distance = 10 cm = 0.1 m

We need to calculate the electric field between the plates

Using formula of electric field

$E = \dfrac{V}{d}$

Where, V = potential difference

d = distance between the plates

Put the formula

$E =\dfrac{12}{0.1}$

$E=120\ V/m$

Hence, The electric field between the plates is 120 V/m.

You have a sealed glass jar full of air. If you put it in the freezer, what happens to the gas pressure in the jar?

Vikki [24]

The pressure of the gas inside the jar decreases, because you have
reduced the temperature of a fixed mass and fixed volume of gas.

While the pressure inside the jar decreases, the pressure outside the
jar doesn't change. So the pressure outside becomes greater than the
pressure inside, and that's why you may see the lid of the jar sag inward,
pushed by the greater pressure on the outside.
