The answer is C. An oxygen atom in heavy water has an extra neutron.

I say this because heavy water is also water, but it contains a higher proportion of the hydrogen isotope – deuterium. Two hydrogen atoms and one oxygen atom makes a water molecule. Deuterium is very much the same as that of normal hydrogen, but contains an extra neutron.

So therefore, the answer is C.

It's
$c) \\$
normal water has only one proton while heavy water (deuterium oxide) has a proton and a neutron

The _____converts sound vibrations into electrical impulses.

Lynna [10]

Answer:

Ossicles

Explanation:

They send the sound waves to the inner ear and into the fluid-filled hearing organ (cochlea). Once the sound waves reach the inner ear, they are converted into electrical impulses.

A quantity of gas has a volume of 0.20 cubic meter and an absolute temperature of 333 degrees kelvin. When the temperature of th

Nesterboy [21]

Answer:

Option C is the correct answer.

Explanation:

By Charles's law we have

V ∝ T

That is

$\frac{V_1}{T_1}=\frac{V_2}{T_2}$

Here given that

V₁ = 0.20 cubic meter

T₁ = 333 K

T₂ = 533 K

Substituting

$\frac{V_1}{T_1}=\frac{V_2}{T_2}\\\\\frac{0.20}{333}=\frac{V_2}{533}\\\\V_2=\frac{0.20}{333}\times 533=0.3198m^3$

New volume of the gas = 0.3198 m³

Option C is the correct answer.

How are igneous rocks formed?

Nana76 [90]

Answer:

What are igneous rocks?

Igneous rocks (from the Latin word for fire) form when hot, molten rock crystallizes and solidifies. The melt originates deep within the Earth near active plate boundaries or hot spots, then rises toward the surface. Igneous rocks are divided into two groups, intrusive or extrusive, depending upon where the molten rock solidifies

1. A baseball that has been thrown is travelling at 40m/s. If

nignag [31]

Answer:

See explanations below

Explanation:

1) KE = 1/2mv²

mass m = 0.142kg

v = 40m/s

KE = 1/2 * 0.142 * 40^2

KE = 1/2 * 0.142 * 1600

KE = 800*0.142

KE = 113.6Joules

2) KE = 1/mv^2

KE = 196

mass m = ?

velocity v = 52m/s

Substitute

196 = 1/2*m*52²

196 = 1352m

m = 196/1352

m = 0.145kg

Hence the mass of the baseball is 0.145kg

3) KE = 1/2mV^2

288 = 1/2 * 4v²

288 = 2v²\

v² = 288/2

v² = 144

v = 12m/s

The velocity of the shotput is 12m/s
