Why did Kenyatta want to distance himself from the Mau Mau? Check all that apply.
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.
(a) The British were determined to crush the rebellion.
(b) They were criminals and made achieving independence more difficult.

A ball has 17 J of kinetic energy and its mechanical is 25 J
If the ball has a mass of 3.2 KG what is it’s height above ground?
Answer:
0.255m
Explanation:
The total mechanical energy of the ball is given 25 J. The potential energy of the ball is 8 J. Then, the height of the ball above the ground is 0.25 m.
What is kinetic energy ?Kinetic energy of an object is the energy generated by virtue of its motion whereas potential energy is generated by virtue of its position at a height from the ground.
The sum of kinetic and potential energy of the object is called its mechanical energy.
given Ke of the ball = 17 J
mechanical energy = 25 J
then potential energy = 25 J - 17 J = 8 J.
We have the relation between potential energy, mass and height h as :
p = mgh .
given the mass m = 3.2 kg
g = 9.8 m/s²
then, h = p / (mg)
h = 8 J / (3.2 kg× 9.8 m/s² )
= 0.25 m.
Therefore, the height of the ball above the ground is 0.25 m.

In a chemical reaction,sodium sulphate and barium chloride are mixed to form barium sulphate(a precipitate)and sodium chloride. (i)What are the reactants in the above reaction? (ii)What are the products?
Answer:
i) The reactants are sodium sulphate and barium chloride
ii) The products are barium sulphate and sodium chloride.
Explanation:
In chemistry, a chemical reaction occurs when one or more chemical substances usually referred to as REACTANTS undergoes some processes and is converted to one or more different substances known as PRODUCTS.
From the question:
Na2SO4 + BaCl2 ⟶ 2NaCl + BaSO4
The above balanced equation represents the chemical reaction between sodium sulphate and barium chloride. Both are the reactants because they where the substances that passed through a process ( this involves the breaking of bond that held them together).
The PRODUCTS are barium sulphate and sodium chloride because they are the substances that presented at the end of the chemical reaction.

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.

a. 750,000 to 6,000,000 meters
b. 0.375 to 3 meters
c. 2,000 to 5,500 meters
d. 0.33 to 2.66 meters
With the use of wave speed formula, below are the answers to the questions
1. C
2. C
3. D
4. B
All the question centered on wave speed, wavelength and wave frequency. The relationship between these three quantities is;
wave speed = wavelength x frequency
That is,
V = Fλ
1. The given parameters are;
V = 1,500 m/s
F = 5 Hz
wavelength λ = V/F = 1500/5 = 300 m
2.) Given that the wavelengths ranging from 2.75 to 16.5 meters and the speed of sound is approximately 330 m/s
When wavelength = 2.75 m
F = V/ λ = 330 / 2.75 = 120 Hz
When wavelength = 16.5 m
F = V/ λ = 330 / 16.5 = 20 Hz
Therefore, the frequencies of thunder humans hear ranges from 20 Hz to 120 Hz
3.) Since the two waves are similar, they will be travelling at the same speed. That is,
Wave speed of X = Wave speed of Y
For wave X and Y respectively;
F = 200 Hz and 700 Hz
λ = 35 m and λm
Find λ of Y by equating the two wave speed. That is,
Fλ for X = Fλ for Y
200 x 35 = 700 λ
λ = (200 x 35)/ 700
λ = 7000 / 700
λ = 10 m
Therefore, The wavelength for wave Y is 10 m
4.) Given that the sea lions frequencies are ranging from 500 to 4,000 hertz. And the speed of sound in sea water is approximately 1,500 m/s
By using the same formula,
V = Fλ
Make wavelength the subject of formula
λ = V / F
When F = 500 Hz
λ = 1500/500 = 3 m
When F = 4000 Hz
λ = 1500/4000 = 0.375 m
Therefore, the approximate wavelengths of sound with which the California sea lions communicate is of the range 0.375 m to 3 m

Hernando builds a simple DC series circuit with a standard D-cell battery and uses an ammeter to determine that the total current in the system is 3.0 A. In an attempt to increase the brightness of the bulbs in the circuit, he tries to increase the voltage by adding two more batteries (in series with the first). Calculate the new current when driven by three batteries.
Answer: I = 9.0 A
Explanation: Ohm's Law is defined as the relationship between voltage and current: in a circuit, the voltage accross a conductor is directly proportional to the current.
The constant of proportionality is Resistance, whose unit is ohm (Ω).
so, Ohm's Law is
V = R.I
It is asked for the current, so, rearraging:
[tex]I=\frac{V}{R}[/tex]
When added two more batteries, the voltage of the circuit triples:
[tex]V_{final}=3V_{initial}[/tex]
Since they are directly proportional, if voltage triples, so does current:
[tex]I_{final}=3I_{initial}[/tex]
[tex]I_{final}=3(3.0)[/tex]
[tex]I_{final}=[/tex] 9.0
The new current, when driven by 3 batteries is 9.0 A.

How much must a man weigh (force) if the pressure he exerts while standing on one foot which has an area of 25 m^2 exerts a pressure of 5 pa?
Answer:
Weight, W = 125 N
Explanation:
Pressure, P = 5 Pa
Area, A = 25 m²
We need to find how much must a man weigh (force) if the pressure he exerts while standing on one foot which has an area of 25 m² exerts a pressure of 5 Pa. So,
Pressure = force/area
So,
[tex]F=P\times A\\\\F=5\times 25\\F=125\ N[/tex]
So, the weight of the man is 125 N.
