Explaination :
Momentum = mass x speed
p = (30 kg) (3 m/s)
p = 90 kg m/s
Answer: e) turbidity
Explanation:
Evaporation is defined as the process by which a liquid without being heated is converted into vapor.
The factors that affect the rate of evaporation of a liquid are:
a) humidity-When the humidity of an environment is high, it will take more time for water to escape to the atmosphere and less time, if the reverse is the case because Humidity is the amount of water vapor in the atmosphere. For example, on a rainy day, clothes tend to dry slower than a sunny day.
b) nature of liquid- different liquids have different rate of evaporation, For example, alcohol will evaporate faster than water
c) pressure - The higher the pressure on the surface of a body of water, the slower the evaporation rate and vice versa.
d) temperature- The temperature of a surrounding affect how fast a liquid ,(water) can evaporate. When the temperature of the liquid is increased, it raises the kinetic energy of the individual molecules that make up the liquid thereby reducing the inter molecular forces of attraction holding the liquid together and causing fast escape into the atmosphere as a vapor or gas
e) turbidity shows the extent water loses its transparency due to the presence of suspended particles lie clay, silt, organic matter etc and so is not a factor that affect rate of evapouration
The initial momentum of the yellow and the orange train is 1000kgm/s.
Momentum is the product of the mass and velocity of any object.
Momentum is denoted by P.
Momentum P = mv , where m = mass and v = velocity.
<h3>Given:</h3>
Mass of the orange train = 200kg
Velocity of the orange train = 1m/s
So, the momentum of the orange train will be,
∴ P = mv
P = 200 x 1
P = 200 kgm/s
∴ The initial momentum of the orange train is 200kgm/s.
Mass of the yellow train = 100kg
Velocity of the yellow train = 8m/s
So, the momentum of the yellow train will be,
∴ P = mv
P = 100 x 8
P = 800 kgm/s
∴ The initial momentum of the yellow train is 800kgm/s.
Therefore, the initial momentum of the yellow and the orange train is 1000kgm/s.
