We can obtain the answer easily if we assume the gas here is an ideal gas. We can use t he expression:
PV = nRT
we set nR/V = k
P/T = k
P1/T1 = P2/T2
when P2 = 3P1
P1/10 = 3P1/T2
T2 = 30 degrees Celsius
It will take 20 seconds for the car to attain a speed of 34 m/s
Explanation:
- Acceleration of an object is given by a = velocity/time.
- Here, acceleration of the car = 1.7 m/s² and velocity = 34 m/s. Using these, find time.
- Time = velocity/acceleration
= 34/1.7 = 20 s
So it takes 20 seconds to attain a speed of 34 m/s
The planet closest to the sun; Mercury.
Answer:
3.6m
Explanation:
if you are at a building that is 46m above the ground, and the professor is 1.80m, the egg must fall:
46m - 1.80m = 44.2m
the egg must fall for 44.2m to land on the head of the professor.
Now, how many time this takes?
we have to use the following free fall equation:
where is the height, is the initial velocity, in this case . is the acceleration of gravity: and is time, thus:
clearing for time:
we know that the egg has to fall for 44.2m, so , and , so we the time is:
Finally, if the professor has a speed of , it has to be at a distance:
and t=3.002s:
so the answer is the professor has to be 3.6m far from the building when you release the egg
Answer:
patron
Explanation:
The patron is something or someone who defends some cause or point of view. In the art field, for example, the patron may be considered a sponsor, that is, someone who is known for defending a particular group of people or specific situation.
The patron is one who advocates, advises and directs. In the military, patrons are heroic figures who are chosen to defend a military unit, for example.
