The question above is simply a conversion problem. We are asked to convert from Celsius to Fahrenheit and to Kelvin. To convert from Celsius to Fahrenheit, we do as follows:
°F = (°C<span> × </span>9/5) + 32
°F = (30 × 9/5) + 32
°F = 86
From Celsius to Kelvin,
K = °C + 273.15
K = 30 + 273.15 = 303.15
Agree because the nutrients are in our blood and they go to the small intestine to help our body function
Answer:
s = 2.16 x 10¹¹ m
Explanation:
Since, the waves travelling from Earth to the Mars rover are electromagnetic. Therefore, there speed must be equal to the speed of light. So, from the equation given below:
s = vt
where,
s = the distance between Earth and Mars = ?
v = speed of the wave = speed of light = 3 x 10⁸ m/s
t = time taken by the radio signals to reach the rover from Earth
t = (12 min)(60 s/1 min) = 720 s
Therefore,
s = (3 x 10⁸ m/s)(720 s)
<u>s = 2.16 x 10¹¹ m</u>
Answer:
the bowling ball, because it has more mass and therefore more inertia
Explanation:
As per law of inertia we know that if an object is having more inertia then it is difficult to change state of motion.
Inertia is the property of mass of an object which always resist to change the state of motion of the object.
If an object has more inertia then it is more difficult to change the state of motion.
Now we know that we have one bowling ball and one basket ball, since bowling ball is having more mass then it must have more inertia so it is difficult to start the motion in bowling ball.
So correct answer will be
the bowling ball, because it has more mass and therefore more inertia
Salt is a compound, with the chemical name "Sodium chloride"
and the chemical formula NaCl.
Each molecule of salt is an atom of sodium electrically bound to
an atom of chlorine.
The chemical properties of salt are completely different from the
chemical properties of either element in its molecule. In fact,
sodium and chlorine are both toxic and corrosive, i.e., poison,
but as long as the salt is still salt, you can safely eat it !
There's nothing physical or mechanical, like spinning or filtering,
that you can do to salt to separate the sodium from the chlorine.
That takes electrical or chemical processes, and once you separate
them, you wind up with two substances that are both dangerous.
If you put salt into a jar with some sand and shake it up, then you
have a mixture. The salt is still salt and the sand is still sand, and
they can be separated quite easily.
If you put some salt in some water, and stir it up so that the salt
dissolves, then you have a salt solution. Some of the salt
molecules actually come apart in it, and there are sodium ions
and chlorine ions in the water. When that happens, the water
begins to conduct electric current very nicely, and if you DO
pass current through it, you get sodium collecting at the end
of one wire, and chlorine collecting at the other wire. But if you
just let it set there in the sun, or heat the solution on the stove,
then once the water evaporates, you have plain old salt again
in the jar.
