Answer Electromagnetic waves are used to transmit long/short/FM wavelength radio waves, and TV/telephone/wireless signals or energies. They are also responsible for transmitting energy in the form of microwaves, infrared radiation (IR), visible light (VIS), ultraviolet light (UV), X-rays, and gamma rays.
Explanation:
Electromagnetic waves are important in society today because they are used to "transmit long/short/FM wavelength radio waves, and TV/telephone/wireless signals or energies. They are also responsible for transmitting energy in the form of microwaves, infrared radiation (IR), visible light (VIS), ultraviolet light (UV), X-rays, and gamma rays."

Carlita’s body is made up of many cells. What is one thing all her cells have in common?
Answer:
All of them have a nucleus..
Explanation:
Pretty simple stuff. There's no cell without one.
Carlita’s body is made up of many cells. The one thing that all her cells have in common is they have the same kind of genes.
What are genes?Genes are tiny pieces of spherical hereditary material that are bead-shaped and found on chromosomes. They hold the organism's genetic makeup. The number of genes on each chromosome is incalculable.
The hereditary material that makes up chromosomes is arranged in x shapes inside the nucleus. DNA, genes, and proteins make it up. An organism's genotype is distinct from other organisms because of its distinct genetic makeup, and this distinction can be passed down from one generation to the next.
Traits may be influenced by genes, the environment, or a mixture of the two. Quantitative features can also be qualitative, such as eye colour (such as height or blood pressure).
Therefore, numerous cells make up Carlita's body. Her cells all share the same type of genes, which is the only thing that unites them.

Which circuit hook-up design will have the brightest light bulb?A - 1 battery 1 bulb, B - 2 batteries 1 bulb, C - 3 batteries one bulb, D 2 batteries the bulb is on the other end, E 1 battery and 1 bulb on the other end
Question 5 options:
A
B
C
D
E
Heres another for you guys!
Answer:
I believe it is E because the battery has a wire, a power source(the battery), and a bulb connected together thus making a full series circuit. Furthermore, the more batteries they are to a series circuit, the more dimmer the light bulbs will be.

How do you think changing the angle of a ramp will affect work done?
Answer: The steepness of a ramp affects it by making it easier or harder.
Explanation: It's a bit situational. If you were going up a steep ramp with a heavy load, it will increase the work necessary, whereas if you were going down a ramp, it would decrease the work necessary. If you need this simply put, think about biking up and down a hill. It would be easier going down than up.
The half life of titanium 44 is 60 years. If you start with 600 grams, how much will be left after 180 years
Answer:
[tex]75\ \text{g}[/tex]
Explanation:
t = Time = 180 years
[tex]t_{1/2}[/tex] = Half-life of titanium = 60 years
[tex]N_0[/tex] = Initial amount of titanium = 600 g
We have the relation
[tex]N=N_0e^{-\lambda t}\\\Rightarrow N=N_0e^{-\dfrac{\ln 2}{t_{1/2}}t}\\\Rightarrow N=600e^{-\dfrac{\ln 2}{60}\times 180}\\\Rightarrow N=75\ \text{g}[/tex]
The mass that is left after 180 years is [tex]75\ \text{g}[/tex].

The burning of a sample of propane generated 1 04.6 kJ of heat. All of this heat was used to heat 500.0 g of water that had an initial temperature of 20.0/C. What was the final temperature of the water?
Answer: 70.0°C
Explanation:
Quantity of heat = Mass * Specific heat * Change in temperature
Quantity of heat = 104.6 KJ
Mass = 500.0 g
Specific heat of water is 4.18 J/g°C
Change in temperature assuming final temperature is x = x - 20
Units should be in grams and joules:
104,600 = 500 * 4.18 * (x - 20)
104,600 = 2,090 * (x - 20)
x - 20 = 104,600/2,090
x = 104,600/2,090 + 20
x = 69.8
= 70.0°C

"You learned about mixtures, especially solutions and the factors that affect their makeup and properties. Why is it important to know the properties of both solutes and solvents when preparing a solution that is expected to meet a certain need?
Does this involve a chemical change or a physical change? Explain."
Can u pls help me
Answer:
its due to the solvents being factored. to be prepared for the solution you would need a chemical change as the solvents get factored so this will mean that it will have a chemical reaction. in this case its slightly different so it will be called a chemical change as 2 different chemicals change and evolve.
