PLS HELP DUE IN 20 MINS!!! True or false: You can make a pulse travel at a faster speed without changing the shape or size of the pulse.
Answer:
False
Explanation:
A Larger pulse with more energy means that the wave has a large amplitude. As in the given question, both the waves are travelling in the same medium, hence their speeds will remain the same and therefore the larger pulse will not overtake the smaller pulse. Remember the amplitude of a wave does not affect the speed at which the wave travels.
PLEASE HELP!!! GIVING BRAINLIEST!! ill also answer questions that you have posted if you answer this correctly!!!! (40pts)
Answer:
Newton's second law: F=ma.
Force = mass x acceleration
This basically means, that the more massive something is, and the faster it is going, the more force the object will have.
So, the factors that can be used to find acceleration are:
F=ma
a=F/m
So, we see that the correct answer is A, mass and force.

Explain how a rock with vesicular texture could form. Give two examples of rocks with this texture.
Answer:
Vesicular texture refers to volcanic rocks that contain holes called vesicles that were formed by gas bubbles in lava. This igneous rock is called scoria. The vesicles form from escaping gas bubbles in cooling lava.
In which of these can convection not occur?
gases
solids
liquids
fluids
Answer:
B: Solids
Explanation:
I have notes from EDG and I looked it up on the internet
I hope this helps
In the solids, convection can not occur. Convection can only be done in the fluids.
What is convection?Under the effect of gravity, hotter, less dense material rises while colder, denser stuff sinks, resulting in heat transfer"Convection is the ultimate mode of energy transmission to the surface"
There are three modes of the heat transfer;
1. Conduction
2. Convection
3. Radiation
Convection occurs in the fluid which is liquid and gases. Convection never occurs in the solid.
Hence option B is correct.

4. A woman releases one egg every month for 37 years. Calculate how many

so, 444 eggs would have been released in 37yrs
If a woman releases one egg every month for 37 years, then she releases 444 eggs.
What is a year?A year is a unit of time that is commonly used to measure the period of time it takes for the Earth to make one revolution around the Sun.
The time it takes for the Earth to complete one orbit around the Sun is approximately 365.24 days, which is why a year is usually defined as 365 days, with an extra day added every four years (in what's called a leap year) to account for the fractional part of the year. This is known as the Gregorian calendar, which is the most widely used calendar system in the world.
A year is also commonly used to refer to the period of time it takes for an event or cycle to repeat, such as the school year, fiscal year, or a company's financial year.
There are 12 months in a year, and they are:
January
February
March
April
May
June
July
August
September
October
November
December
Each month has either 30 or 31 days, except for February which has 28 days (or 29 days in a leap year). The number of days in a month determines the number of days in a year, which is why a year typically has either 365 or 366 days, depending on whether or not it is a leap year.
Here in the question,
37 years is equivalent to 37 x 12 = 444 months (since there are 12 months in a year).
To calculate this, we simply multiply the number of eggs released each month (which is one) by the total number of months:
Number of eggs released = 1 egg/month x 444 months
Number of eggs released = 444 eggs
Therefore, over 37 years, a woman releases 444 eggs.

The deeper you dive into the ocean and the higher the altitude you gain when climbing a mountain result in what?
Answer:
A change in pressure
Explanation:
This is because, the deeper you dive, the height of water above you creates a pressure on you. So, as the depth increases, the height of water increases, thus its weight on you, thus its pressure on you also.
Also, as you gain altitude as you climb a mountain, the height of air above you decreases. This thereby decreases the weight of air above you thus, decreasing the pressure of air on you.
So, in both cases, there is a change in pressure as height or depth changes. An increase in height results in decreased pressure and an increases in depth results in increased pressure.

If dan ran the 100m dash in 10.23s. What was his average speed during the race? (Round to the nearest tenth of a second)
Answer:
.1 seconds per meter
Explanation:
I am going to assume they are asking for the average time per 1 meter.
Because it took 10.23 seconds to run 100 meters, we are going to divide 10.23 by 100. This number will be the time per 1 meter.
To divide by 100, we will move the decimal point over by two. That will give us .1023 seconds.
The question asks to round to the nearest tenth, so we round it to .1 seconds.
*Just some trivia: Danie van Blerk does in fact have a time of 10.23 seconds. He has the 1073rd best 100 meter dash time. First place, Usain Bolt, has a time of 9.58 seconds.

Describe the relationship between the materials and amount of thermal energy transfer?
Answer:If you mean how much heat it can transfer as a thermal mass - in order to move heat from one place to another:
Typically the relationships are given by specific heat capacity (at different temperatures) and latent heats, plus the end-point temperatures to determine which of these conversion factors are relevant.
If time comes into it, you are looking at including shape and thermal conductivity at the minimum, so you really would need to be more specific

They had no desire for independence.
The British were determined to crush the rebellion.
They were criminals and made achieving independence more difficult.
They were led by his political rivals.
They were members of the Kikuyu.
Answer:
The British were determined to crush the rebellion.
They were criminals and made achieving independence more difficult.
Explanation:
Mau-mau were rebellions and wanted to push out British and other Europeans out of Kenya. Mau mau were also the members of the Kikuyu and were making independence more difficult, due to their rebellion attitude. They were a secret society of Kikuyu.
2) The British were determined to crush the rebellion.
3) They were criminals and made achieving independence more difficult.
After British victory in World War II, Kenyatta received a request to return to Kenya in September 1946, sailing back that month. He decided not to bring Edna—who was pregnant with a second child —with him, aware that if they joined him in Kenya their lives would be made very difficult by the colony's racial laws. On his arrival in Mombasa, Kenyatta was greeted by his first wife, Grace Wahu and their children. He built a bungalow at Gatundu, near to where he was born, and began farming his 32-acre estate.

What advice would you give her to improve her diagram? Choose all that
apply.
Answer:
A, C
Explanation:
In order for a box to be moving at constant velocity, that means acceleration must be 0(as the speed isn't increasing). Thus, since F = ma, and a is 0, the net force must also be 0. The diagram must be completely balanced in every direction, which is why the two horizontal arrows must be equal values.
C is also true because gravity is a stronger force here than the applied force. We can calculate the force due to gravity with Fgravity = mg. Thus, we get the force as a result of gravity = 9.8*50, which is around 500N and much larger than the applied force of 200N.

you push a shopping cart with 2 packs of water bottles. you stop the cart and add two more packs. you push the cart again. does the cart behave differently? explain using science terms.
Answer:
Yes
Explanation:
The cart will definitely behave differently because more weight is added to it.
In order to successfully push a cart, the applied force must exceed the force of the weight of the cart along with its constituents and the frictional force between the tyres and the floor.
When more weights are added (the 2 packs of water bottles), it means that more force would be needed to overcome the opposing forces to the movement of the cart in order to successfully push the cart again.

Find the magnitude of the sum of a 10m displacement and a 5 -m displacement when the angle between them is 45
Answer:
The magnitude of the resultant of the two vectors is 7.37 m.
Explanation:
let the first vector = a = 10 m
let the second vector = b = 5 m
angle between the two vectors, θ = 45⁰
The magnitude of the resultant of the two vectors is calculated as;
[tex]R^2 = a^2 + b^2 -2ab \times cos(\theta)\\\\R^2 = 10^2 + 5^2 - [2\times 10 \times 5 \times cos(45)]\\\\R^2 = 125 - [100 \times 0.7071]\\\\R^2 = 125 -70.71\\\\R^2 = 54.29 \\\\R= \sqrt{54.29} \\\\R = 7.37 \ m[/tex]
Therefore, the magnitude of the resultant of the two vectors is 7.37 m.
