Which characteristics belong to Whittaker’s classification system? Select two options.
a.three domains
b.six domains
c.two kingdoms
d.five kingdoms
e.five levels
f.seven levels
g.eight levels
Answer:
Five kingdoms & Seven levels
Explanation:
Robert H. Whittaker proposed five kingdom classical system for living organisms in 1969. These were: Kingdom Monera, Kingdom Protista, Kingdom Fungi, Kingdom Animalia, and Kingdom Plantae. His work was the improvement of earlier work conducted by Carl Linnaeus who proposed three kingdom classification system (Animalia, Plantae, and Protista).
Whittaker's system further categorized each kingdom to seven levels. These were: Kingdom → Phylum → Class → Order → Family → Genus → Species. This categorization was based on similarities in organisms at different levels.
PS: The scientific name of each organism is the combination of genus and family name.
This is a schematic for a clothes dryer appliance. This appliance dries clothes primarily by converting--
A) Thermal energy into electrical energy
B) Electrical energy into thermal energy and mechanical energy
C) Kinetic energy into thermal energy
D) Electrical energy into mechanical energy
The cloth dryer appliance works on the energy transformation from electrical energy into mechanical energy and thermal energy. Hence, option B is correct.
What is energy transformation?According to energy conservation law, energy can neither be created nor be destroyed but it can be transformed from one form to the other. Thus, energy lost by one form can be gained in other form.
In electrical devices, electrical energy is converting to various other forms. For instance, in lamps, electrical energy is converted to the light energy. Similarly in fan electrical energy is converted to the mechanical energy.
In a cloth dryer the electrical energy is converted to the mechanical energy to make it operate and this further produces the thermal energy sufficient to dry the clothes.

3.Use the equation to provide additional support for your prediction
Answer:
Solids keep their shape and cannot be compressed. Let us see if the particle model can help us understand why solids behave in this way.
In a solid, the particles are packed close to each other in fixed positions. They are locked into place, and this explains why solids have a fixed shape. Look at the following images of sodium chloride (table salt). Do you remember the formula for sodium chloride?
Macroscopic view of sodium chloride
Submicroscopic view of sodium chloride
Table salt crystals are hard and have a fixed shape.
Can you see how the chloride atoms (purple) alternate with the sodium atoms (yellow) in a fixed arrangement?
Take a good look at the picture of the particles in a solid (table salt) above. You will see that they are packed in a regular arrangement. There are very small spaces between the particles in a solid.
Particles are held together by forces of attraction. In solids, these forces are strong enough to hold the particles firmly in position.
Does that mean the particles in a solid do not move at all? No. The particles in a solid move a little bit. They vibrate in their fixed positions. The more energy the particles have, the faster and more strongly they vibrate.
Do you see how we have used the particle model of matter to explain the properties of solids that we can observe? For example, the particles in solids are closely packed and have strong forces between them explains why solids have a fixed shape and you cannot compress them.
The liquid state
An important characteristic of liquids is that they flow. They fill containers they are poured into. Liquids are also not very compressible. How can these properties be explained?
Orange juice is a liquid, which can be poured.
In the liquid state, particles do not have fixed positions. They move about freely, but they stay close together because the forces of attraction between them are quite strong, but not as strong as in solids.
Have you noticed how a liquid always takes the shape of the container it is in? Within the liquid, the particles slip and slide past each other. This is why liquid flows. Their particles are free to move around, filling the spaces left by other particles. Look at the image of the juice being poured. Let's zoom in and have a look at what the particles are doing as the juice is poured.
The particles in a liquid have small spaces between them, but not as small as in solids. The particles in a liquid are loosely arranged which means they do not have a fixed shape like solids, but they rather take the shape of the container they are in.
The speed at which the particles move around inside the liquid depends on the energy of the particles. When we heat a liquid, we are giving the particles more energy and speeding them up.
In gases, the particles move at even greater speeds.
The gaseous state
Gases spread out quickly to fill all the space available to them. Think of when you blow up a balloon. The air that you blow into the balloon fills up the whole balloon. A gas will fill the entire space that is available to it. This is because the particles in a gas have no particular arrangement.
Gases do not have a fixed shape. Think about the balloon again: the gas fills the entire space inside the balloon. You can squeeze the balloon, changing the shape.
Gases fill the space available to them.
Gases do not have a fixed shape.
Gas particles move very fast, much faster than in solids and liquids. The particles in a gas possess a lot of energy.
Have you ever tried to compress the gas in a syringe or in a bicycle pump? Why do you think you can compress the gas?
In gases, the forces between particles are very weak. This explains why the particles in gases are not neatly arranged. They are not held together tightly and there are large spaces between them. These spaces are much larger than in the solid and liquid state.

a. resistance
b. friction
c. induction
d. voltage
The correct option is, (d) voltage.
The difference in electrical potential energy between two places is called voltage.What is the difference in electrical potential energy between the two places?The external effort required to move a charge in an electric field from one position to another is known as an electric potential difference, or voltage. A test charge with a value of +1 will experience an electric potential difference, which is a shift in potential energy.What is a difference in electric potential energy?The electric potential difference is the difference in electric potential (V) between the final and the initial location when work is done upon a charge to change its potential energy.What is the potential difference between two charges?The word "potential difference" refers to the magnitude of the electrostatic force acting between two charged objects. Depending on the polarity of the objects, a charged body will attempt to travel in one direction if it is placed between two objects with a potential difference.Learn more about electrical potential energy here:

A baseball is thrown at 90 mph from east to west over a distance of 60 ft. What is
true of the ball's motion?
Its speed is 90 mph to the west.
Its acceleration is 30 mph.
Its velocity is 90 mph to the west.
Its acceleration is 150 mph.
Answer:
Its acceleration is 30 mph.
Explanation:
The true of the ball's motion will be that the velocity is 90 mph to the west. Velocity is the vector quantity. Because it shows the direction.
What is acceleration?
Acceleration is defined as the rate of change of the velocity of the body. Its unit is m/sec². It is a vector quantity. It requires both magnitudes and direction to define.
The given data in the problem is
The velocity of baseball is,V= 90 mph
The distance travelled in mile is; d=0.0113636 mile
The time period is obtained as;
[tex]\rm t = \frac{d}{v} \\\\ \rm t = \frac{0.0113636}{90} \\\\ t=1.2 \times 10^{-4} \ hr[/tex]
The acceleration is obtained is 0.00108 mile/hr².
Hence, the true of the ball's motion will be that the velocity is 90 mph to the west.
