Answer:
hope this helps
Explanation:
Coating surfaces with oil reduce friction between the surfaces because it is like when lubricating a machine, it makes it run or it makes it become smoother.
Both travel in waves caused by vibrations. Both can be reflected refracted, and diffracted.
Good morning.
Yes, it is possible.Energy is a scalar quantity. The value of the potential energy is calculated the following way:
Where
m is mass,
g is the acceleration of gravity and
h is the height.
Note that the height depends on the adopted referential, therefore, if we adopt, for example, a referential on the floor, if we dig a hole that has a depth of 1 meter, a ball that is put inside the hole will have negative potential energy due to the adopted referential, since
h is negativa in this case.
Answer:
D. 20.4m
Explanation:
assuming there is no initial velocity, where v=final velocity, g=acceleration due to gravity, and t=time
v = g*t
20 = 9.8*t
t =2.03 s
y = (1/2) g t^2 where y=vertical distance, g=acceleration due to gravity, and t=time
y = 4.9 (2.03)^2
y = 20.4 meters
1. What food were you craving the most upon return home after eating space food? - I would ask because they don’t get the regular everyday food we have on earth, I know I’d be craving food and it’s very interesting to hear their answers.
2. How did you feel physically after returning to earth? And has it been hard readjusting? - After a long period of time in space, I feel like it’d be very hard to adjust back into the way we live and I’m intrigued to hear about how it felt and what they did in order to adjust.
3. What do you think while on the launchpad about to launch? - I feel like it’d be very scary for me but everyone has a different way of feeling. I’d love to hear about their thoughts during this process.
