Do you have the answer for this question? so i can provide u solution more effectively
Therefore, the volume of the gas at temperature 100°C is 4.62L
<u />
<u>Explanation:</u>
Given-
Volume, V1 = 4L
Temperature, T1 = 50°C = 50 + 273K = 323K
Temperature, T2 = 100°C = 100 + 273K = 373K
Volume, V2 = ?
Using Charles law:
V1/T1 = V2/T2
4/323 = V2/373
V2 = 4.62L
Therefore, the volume of the gas at temperature 100°C is 4.62L
Answer:
Explanation:
1 ) Total mechanical energy of the car at the height of 10 m
1/2 mv² + mgh
.5 x 1800 x 25² + 1800 x 9.8 x 10 m
= 562500 + 176400
738900 J
If v be the velocity at the bottom ,
Total energy of the car at the bottom
1/2 m v² + 0
Applying conservation of energy
1/2 mv² = 738900
.5 x 1800 v² = 738900
v = 28.65 m /s
Energy required by car to ascend height of 15 m
1800 x 9.8 x 15
= 264600 J
b )
This energy is more that total energy of the car at the top that is 738900 J
so car can easily reach gas station .
If V be the velocity at the gas point
Total energy at the gas point
1/2 m V² + 264600
Applying conservation of energy
1/2 m V² + 264600 =738900
.5 x 1800 x V² = 474300
V = 22.95 m / s
d ) If R be the normal reaction at the bottom
net force
R - mg = m v² / r
R = m ( g + v² / r )
1800 ( 9.8 + 28.65² / 5 )
R = 313136 N
The answer for the cars speed is tue
