Answer:
2 × 10⁸J/kg
Explanation:
Specific latent heat of vaporization (steam) is the quantity of heat required or needed to change a unit of mass of liquid to gaseous state at constant temperature (boiling point) and pressure.
It can be calculated mathematically using,
Q = mL
Where, Q = quantity of heat
m= mass in kg
L = specific latent heat (J/kg)
Therefore,from the question
Q= 15000000J
mass (m) = 75g = 75/1000 kg = 0.075kg
Q = mL
L = Q/m
L = 15000000 ÷ 0.075
L= 200000000J/kg
L = 2 × 10⁸J/kg

The correct answer is d. deterioration of brain tissue. A brain ventricle is a fluid filled structure located in the parenchyma. The fluid in the ventricles is called cerebro-spinal fluid. An increase in the volume of this fluid can lead to a condition known as hydrocephalus.
Answer:
C. 150 N to the left
Explanation:
If we take right to be positive and left to be negative, then:
∑F = -450 N + 300 N
∑F = -150 N
The net force is 150 N to the left.
The correct option is D.
The critical angle is defined as the angle of incidence, which provides an angle of refraction of 90 degree. At any angle of incidence greater than the critical angle, all the light will totally reflected, resulting in total internal reflection.Thus, the critical angle is equal to the refractive index.
