Answer: Wheel and Axle
Both of these work together to form a simple machine. You can't have one without the other.
If you try to turn just the axle itself, then you'll find it takes a lot of work. This is because the inertia of the axle wants to keep the object at rest. Also, you won't have a lot of torque due to the small radius compared to what a doorknob can offer.
Using a doorknob is like putting a (steering) wheel on an axle. This increases the radius and therefore increases the torque. You put in less work into the system and get more out of it.
LMBO, for science.
Answer:
<em>The increase in kinetic energy leads to leakage of water from the syringe. When the outside temperature is more than the liquid temperature, say the syringe is out in sunshine, then the liquid becomes slightly warmer.</em>
no the best source is blood.
I think the answer is B. static charge. I hope this helps! :)
Answer: Assuming the question: 3.54 ml (3 sig figs)
Explanation:
I don't see a question, but will assume it is "What volume is needed to obtain 26.5 grams?
If so:
(26.5 g)/(7.48 ml) = 3.54 ml (3 sig figs)
