Answer:
When friction hits the floor, the oil bounces back up but then down. Then the oil spreads apart. Like an earthquake. Not really though. And try not to spill oil for the first place.
Hope I helped! Brainiest plz! Hope you make an 100% and have a wonderful day! -Amelia♥
Answer:
12.974 m/s
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
g = Acceleration due to gravity = 9.81 m/s²
= Coefficient of friction =0.66
a = Acceleration = ![\mu g](https://tex.z-dn.net/?f=%5Cmu%20g)
![v^2-u^2=2as\\\Rightarrow -u^2=2\mu gs-v^2\\\Rightarrow u=\sqrt{v^2-2\mu gs}\\\Rightarrow u=\sqrt{0^2-2\times -(9.81\times 0.66)\times 13}\\\Rightarrow u=12.974\ m/s](https://tex.z-dn.net/?f=v%5E2-u%5E2%3D2as%5C%5C%5CRightarrow%20-u%5E2%3D2%5Cmu%20gs-v%5E2%5C%5C%5CRightarrow%20u%3D%5Csqrt%7Bv%5E2-2%5Cmu%20gs%7D%5C%5C%5CRightarrow%20u%3D%5Csqrt%7B0%5E2-2%5Ctimes%20-%289.81%5Ctimes%200.66%29%5Ctimes%2013%7D%5C%5C%5CRightarrow%20u%3D12.974%5C%20m%2Fs)

Answer:
a. There is a force on Jupiter toward the center of the orbit.
d. Jupiter is accelerating toward the center of the orbit.
Explanation:
Let us look at each of the choices one by one:
a. There is a force on Jupiter toward the center of the orbit.
True. The sun being at the center of Jupiter's orbit, pulls the planet towards it (providing the centripetal force), therefore, there exists a force on Jupiter toward the center of the orbit.
b. There is a force on Jupiter pulling it out from the center of the orbit.
Nope. The centripetal force due to gravity acts towards the center of the orbit.
c. There is a force on Jupiter in the direction of its motion.
Nope. There exists only the centripetal force acting towards the center of the orbit,
d. Jupiter is accelerating toward the center of the orbit.
Yes. Because of the centripetal force gravity provides, Jupiter is accelerating towards the center of the orbit, but it does not fall in because it has velocity perpendicular to the direction of its acceleration.
Answer:
3. you need to ask your available lab instructors what to do.
4. You immediately have to drop down your cloth and roll it to extinguish the fire or move to the emergency shower if available
5. You have too keep calm and report to the lab instructor but do no shout.
6. Move immediately to the eye rinse basin if available and wash your eyes gently and thoroughly
