Hello,
Well, Liquids don't have a fixed shape, but they do have a fixed volume.
So the answer would be Neon gas
Answer:
C) 1200 rpm
Explanation:
= Diameter of bigger pulley = 24 inch
= Diameter of smaller pulley = 8 inch
= Speed of bigger pulley = 400 rpm
= Speed of smaller pulley
The relation between revolutions per minute and diameter is that they are inversely proportional.
The number of revolutions per minute of the smaller pulley is 1200 rpm
Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.
Good experimental design includes a hypothesis that is <span>testable and observable.</span>
<span>a wave in a spring and a P wave are longitudinal waves. Both waves have compression and rarefaction

Answer:
m = 69.9 kg
Explanation:
The mass and the weight of an object are two different quantities. Mass is basically the amount of matter that is present in a body. It remains same everywhere in the universe and measured in kilograms.
Weight is basically a force. It is the force by which earth attracts everything towards itself. The weight of an object changes from planet to planet, with the change in value of the gravitational acceleration (g).
Therefore, the relation between mass and weight of an object is given by the following formula:
W = mg
m = W/g
where,
m = mass = ?
W = Weight = 685 N
g = 9.8 m/s²
Therefore,
m = (685 N)/(9.8 m/s²)
<u>m = 69.9 kg</u>
