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
what causes waves to slow down: change in wave’s wavelength or change in its frequency and y?
Answer:
Although the wave slows down, its frequency remains the same, due to the fact that its wavelength is shorter. When waves travel from one medium to another the frequency never changes.

According to Newton's third law, what other force must be happening?
Answer:
The desk is pushing back on Arianna
Explanation:
If you read newton's 3rd law, it states that for every action force (Arianna pushing the desk), there is an equal reaction force (The desk pushing back on her). This is true for EVERY OBJECT THAT HAS MOTION!

3. A beam of light passes through the air (n=1.00) and enters a diamond (n=2.42) at an angle of incidence of 40 degrees. Use Snell’s Law to find the angle of refraction in the diamond. If the diamond is placed in a tank of water (n=1.33) and the beam of light enters the diamond at the same angle of incidence, what would be the new angle of refraction? Show all work.
Answer:
(a) θ₂ = 15.4°
(b) θ₂ = 28.9°
Explanation:
Snell's Law can be written as follows:
[tex]n_1Sin\theta_1 = n_2Sin\theta_2[/tex]
where,
n₁ = incident index
n₂ = refracted index
θ₁ = Angle of incidence
θ₂ = Angle of refraction
(a)
n₁ = incident index = 1
n₂ = refracted index = 2.42
θ₁ = Angle of incidence = 40°
θ₂ = Angle of refraction = ?
Therefore,
[tex](1)(Sin\ 40^o) = (2.42)Sin\theta_2\\\theta_{2} = Sin^{-1}(0.26561)[/tex]
θ₂ = 15.4°
(b)
n₁ = incident index = 1
n₂ = refracted index = 1.33
θ₁ = Angle of incidence = 40°
θ₂ = Angle of refraction = ?
Therefore,
[tex](1)(Sin\ 40^o) = (1.33)Sin\theta_2\\\theta_{2} = Sin^{-1}(0.4832)[/tex]
θ₂ = 28.9°

Consider a projectile. Which of the following describes y-motion? Check all that apply.
1. The y motion is a vertical motion.
2. The y motion is a horizontal motion
3. A projectile covers different distances per second in the direction.
4. A projectile covers equal distance per second in this direction
Answer:
1. True - gravity affects the y motion
2. False - x-coordinates affect the horizontal motion
3. y because gravity affects motion in the y-direction
4. x generally no external forces act in the x direction and hence no acceleration in the x direction

7. Explain what happens to the volume of a sphere when the radius is tripled?
ANYONE PLS ASAPPPPPPP
[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the concept of surface areas and Volumes.
When the radius is 'r', we get as,
V = 4/3*(π)(r^3)
when the radius is tripled that is '3r' , we get as,
V' = 4/3 (π)(3r)^3
V' = 27*(4/3(π)(r^3))
V' = 27 V
hence the new volume, when radius is tripled, is 27 times greater than the old sphere.

About 40,000 J of energy is stored in a typical 1.5-V D-cell battery. If two such batteries are joined to produce a total of 3.0 V in a flashlight circuit and cause 2.0 A of current to flow through the flashlight bulb, how long will the batteries be able to deliver power to the flashlight at this level?
URGENT PLS HELP
Answer:
Time = 13333.33 s = 222.22 min = 3.7 h
Explanation:
The total amount of energy in two cells combined will be:
[tex]Total\ Energy = 40000\ J + 40000\ J\\Total\ Energy = 80000\ J\\[/tex]
Now, we calculate the power of the batteries:
[tex]Power = (Voltage)(Current)\\Power = (3\ V)(2\ A)\\Power = 6\ Watt[/tex]
Now, we use the following formula to calculate the time the batteries will be able to deliver the power to the flashlight:
[tex]Total\ Energy = (Power)(Time)\\\\Time = \frac{Total\ Energy}{Power}\\\\Time = \frac{80000\ J}{6\ Watt}[/tex]
Time = 13333.33 s = 222.22 min = 3.7 h
A 0.547 kg pizza is thrown straight up in the air. At a height of 2.30 m above the surface of the earth it has a speed of 5.00 m/s. Calculate the total mechanical energy of the pizza crust.
Answer:
The total mechanical energy of the pizza crust is 19.2 J.
Explanation:
Mechanical energy is that which a body or a system obtains as a result of the speed of its movement or its specific position, and which is capable of producing mechanical work. Then:
Potential energy + kinetic energy = total mechanical energy
Kinetic energy is a form of energy. It is defined as the energy associated with bodies that are in motion and this energy depends on the mass and speed of the body.
Kinetic energy is defined as the amount of work necessary to accelerate a body of a certain mass and in a position of rest, until it reaches a certain speed.
Kinetic energy is represented by the following formula:
Ec = ½ *m*v²
Where Ec is kinetic energy, which is measured in Joules (J), m is mass measured in kilograms (kg), and v is velocity measured in meters over seconds (m / s).
In this case:
m=0.547 kgv= 5 m/sReplacing:
Ec = ½ *0.547 kg*(5 m/s)²
and solving you get:
Ec= 6.8375 J
On the other hand, potential energy is the energy that measures the ability of a system to perform work based on its position. In other words, this is the energy that a body has at a certain height above the ground.
Gravitational potential energy is the energy associated with the gravitational force. This will depend on the relative height of an object to some reference point, the mass, and the force of gravity. Then for an object with mass m, at height h, the expression applied to the gravitational energy of the object is:
Ep = m*g*h
Where Ep is the potential energy in joules (J), m is the mass in kilograms (kg) is h the height in meters (m) and g is the acceleration of fall in m / s² (approximately 9.81 m/s²)
In this case:
m= 0.547 kgg= 9.81 m/s²h= 2.30 mReplacing
Ep= 0.547 kg *9.81 m/s²* 2.30 m
and solving you get:
Ep= 12.342 J
So:
Total mechanical energy= 12.342 J + 6.8375 J
Total mechanical energy= 19.1795 J≅ 19.2 J
The total mechanical energy of the pizza crust is 19.2 J.
