Explanation:
It is given that,
A nerve signal travels 150 meters per second. It is the speed of the nerve signal. We need to convert the number of kilometers that the nerve signal will travel in the same time.
We know that,
1 kilometer = 1000 meter
1 hour = 3600 seconds
So, the nerve signal will travel at the rate of 540 km/h. Hence, this is the required solution.
Answer:
The air fraction to be removed is 0.11
Given:
Initial temperature, T = = 283 K
Pressure, P = 250 kPa
Finally its temperature increases, T' = = 318 K
Solution:
Using the ideal gas equation:
PV = mRT
where
P = Pressure
V = Volume
m = no. of moles of gas
R = Rydberg's Constant
T = Temperature
Now,
Considering the eqn at constant volume and pressure, we get:
mT = m'T'
Thus
(1)
Now, the fraction of the air to be removed for the maintenance of pressure at 250 kPa:
From eqn (1):
Answer:
see below
Explanation:
The position graph will be a horizontal line (of constant position) located at the negative value representing the position to the left of the origin.
The velocity graph will be a horizontal line at 0, since the object is at rest.
The acceleration graph will be a horizontal line at 0, since the object's velocity is not changing.
