<span>We know that the relation between pressure, volume and temperature is constant for ideal gases, so then
P1*V1/T1 = P2*V2/T2
As the volume is held constant, we will have:
P1/T1 = P2/T2
As the pressure is doubled and the temperature in kelvins is 211.15 K, then:
P1/211.15 = 2*P1/T2
T2 = 2*211.15 = 422.3 K
T2 = 422.3 - 273.15 = 149.15
So the final temperature reaches 149.15 ÂşC</span>
Answer:
They die horrifically.
Explanation:
Basically, light is their food source, without light they die, it can only be sunlight, or lights that mimic sunlight. Imagine dying of starvation...
Sheesh, that must be painful.
Answer:
216
you have to change the meters per second to meters per minute, so you multiply .12 by 60 and get 7.2, then you multiply 7.2 meters per minute by 30 minutes and get 216
Answer: Option B: 1.3×10⁵ W
Explanation:
Work Done,
Where s is displacement in the direction of force and F is force.
where, v is the velocity.
It is given that, F = 5.75 × 10³N
v = 22 m/s
P = 5.75 × 10³N×22 m/s = 126.5 × 10³ W ≈1.3×10⁵W
Thus, the correct option is B
Answer:
C) 10 cm
Explanation:
We shall first calculate the focal length of the mirror.
object distance u = 20 cm ( negative )
Image distance v = 12 cm ( negative )
using mirror formula
1/ v + 1 /u = 1/ f
-1/12 - 1/ 20 =1/ f
f =- 7.5 cm
In the second case
u = - 30 cm
f = - 7.5 cm
i / v + 1 / u = 1 / f
1 / v - 1/30 = - 1/ 7.5
v = -10 cm
Answer is C that is 10 cm
