16 is 2/5 17 is 1/3 18 is 4/4
At 350 K the approximate volume is 83 dB.
The Volume is much louder at 900 K
Answer:
If the force on a cart doubles, the acceleration of the cart doubles.
Explanation:
For this problem, we need to consider the following equation:
Force = Mass x Acceleration
We can reasonably assume that the cart will have constant mass in the given force system. With this assumption we can say the following relationship:
Force is directly proportional to Acceleration within the system.
Given that our force on the cart is doubled, then our acceleration of the cart must also be doubled. You can mathematically express this as follows:
F = MA
2F = M * 2A
Hence, if force doubles, the acceleration doubles.
Cheers.
The question has examples of all 3 of Newton's laws of motion.
You just have to know which is which.
Hockey puck . . . First law; law of 'inertia'
Tractor trailer vs sports car . . . Second law; F = M A
Swimmer and raft . . . . . THIS is the third law; action force and REaction force
Car in a fast turn . . . . . First law; another example of inertia
Answer:
If the sun's mass were to double without pushing or pulling on the Earth, then the Earth's orbit will change to an ellipse which brings it out to our current radius but spends most of its time closer to the sun. The tides would probably get even stronger then, particularly when our orbit takes us closer to the sun.
