Answer:
1kg of oxygen(918joules of energy per 1kg of oxygen by 1 degree Celsius)
<span>The polarity of a water molecule
comes from the uneven distribution of electron density of hydrogen and oxygen
atom. The oxygen in the water molecule is more electronegative than the
hydrogen. Water has a <u>partial positive charge near the hydrogen atom and a
partial negative charge near the oxygen atom</u>. The result of this
electrostatic attraction results in the bond called hydrogen bond. Also, because
of this bond, it has the ability to dissolve most of the solutes due to its
polarity and bonding.</span>
Snell's law.
1=incident
2=refracted
Since it's coming out of the amethyst into air:
n1=1.55
n2=1.0003
=
°
Substituting back into Snell's equation we get
so the angle is
°
<span>Imagine rolling a bowling ball down the alley. Rolling the ball forward simply moves it forward. However, when rolling forward with a rotation going clockwise, the ball starts to curve in that direction. Similar concept is applied to the baseball as it travels through the air. The spin influences its trajectory as it travels from point A to point B.</span>
Answer:
this statement is true.
Injuries can be prevented if you follow the rules, use protective equipment, and know the risks of injuries involved in each sport.
injuries can be prevented if we follow the rules and know the risk of injuries because there’s a very famous proverb “prevention is better than cure”.
