Answer:
Explanation:
We can solve this problem using the ideal gas law
where P is the pressure, V the volume, n the number of moles, R the ideal gas constant and T the temperature.
We can use the atmospheric pressure as 1 atm, and the body temperature as 36.5 °C, in Kelvin this is:
The ideal gas constant is:
taking all this in consideration, the number of moles will be:
* 309.65 \ K } [/tex]
Answer:
15km/h
Explanation:
Time taken to complete 30km/h=2 hours=15km/h hence the average speed is 15km/h.
Changing the medium of the wave.
Waves is always determined by the properties of the medium, which means that changing the medium will change the velocity of the wave
Answer:
209.66 m
Explanation:
Given:
Original length of the spaceship, L = 481 m
Speed of the spaceship, v = 2.70 × 10⁸ m/s
Now,
using the concept of length contraction, we have
where,
L' is the observed length
c is the speed of the light
Thus,
on substituting the respective values, we get
or
L' = 209.66 m
Okay, haven't done physics in years, let's see if I remember this.
So Coulomb's Law states that
so if we double the charge on
and double the distance to
we plug these into the equation to find

So we see the new force is exactly 1/2 of the old force so your answer should be
if I can remember my physics correctly.
