Explanation:
It is given that,
The position of a particle is given by :
(a) Velocity of a particle is given by :
Putting values,
The acceleration of the particle is given by :
(b) At t = 0,
Velocity, v = 6k m/s
Acceleration, a = 6i m/s²
H = 2.80t^3
h = 2.80 (1.55)^3 = 10.43
10.43 = 1/2 gt^2
10.43 x 2/9.8 = t^2
t = √2.12
= 1.45

Answer:
Option C is the correct answer.
Explanation:
We have ideal gas equation, PV = nRT
Volume of tank, V = 1 m³
Mass of water = 10 kg
Mass of 1 mole of water = 18 g = 0.018 kg
Number of moles,
Temperature, T = 160 °C = 160 + 273 = 433 K
Ideal gas constant, R = 8.314 JK⁻¹mol⁻¹
Substituting
P x 1 = 555 x 8.314 x 433
P = 2000000 Pa = 2000 kPa
The pressure in the tank is 2000 kPa
Option C is the correct answer.
