We can use the ideal gas
equation which is expressed as PV = nRT. At a constant volume and number of
moles of the gas the ratio of T and P is equal to some constant. At
another set of condition, the constant is still the same. Calculations are as
follows:
T1/P1 = T2/P2
T2 = P2 x T1 / P1
T2 = 225 x 300 / 198
<span>T2 = 340.91 K</span>
Answer:
119.42 x 10⁻³ m
Explanation:
The distance of first dark fringe from central bright spot will be equal to the width of fringe .
Fringe width = λL /w
where λ is wavelength of light, w is slit width , L is distance of screen .
So required distance
= 
= 119.42 x 10⁻³ m
Answer:
149.96J
Explanation:
Given parameters:
Number of stairs = 33
Height = 0.25m
Weight = 599.85N
Unknown:
Energy the person takes to reach the top = ?
Solution:
To solve this problem;
The energy it takes is given as:
Energy = weight x height
Energy = mass x gravity x height
Now,
Insert the given parameters and solve;
Energy = 599.85 x 0.25 = 149.96J
By pumping out all air from a large tube, we basically formed an environment that is vacuum in nature inside the tube. So, air resistance is no longer a factor in the descent of the feather and the steel ball. These objects will fall at the same time to the end of the tube.
M/s absorbed per second, is simply the external force, relationship between theforce<span> on an object and the </span>rate of change<span> of its </span>momentum<span>; valid only if the </span>force<span> is constant.
