Ruth knows she has a 25% chance of having a child with blue eyes and a 75% chance of having a child with brown eyes
Part A
Ruth considers making a spinner to simulate the probability of having three children with blue eyes. Describe what the spinner should look like and the steps she should take to perform the
simulation
Respond in the space provided
Part B
Ruth used a spinner to perform 10 trials to simulate the probability of having three children with blue eyes She observed 1 outcome of having three children with blue eyes.
• Is Ruth's estimated probability representative of the theoretical probability of having three children with blue eyes? Explain why or why not.
• Provide the estimated probability from Ruth's simulation and the theoretical probability of having three children with blue eyes
Respond in the space provided
Answer: There is two event that needs to be made: 1. blue eyes, and 2. brown eyes. A spinner is made with a circle. A full circle has 360 degrees and it would be divided based on the probability of the event.
Blue eyes have 25% chance, so the angle of the spinner would be 25%*360°= 90°
Brown eyes have 75% chance, so the angle of the spinner would be 25%*360°= 270°
So, the 90° of the circle would be written as 1(blue eyes) and 270° of the circle will be written as 2(brown eyes).

WHAT IS SOUND? EXPLAIN ITS WAVES
Answer:
sound is made up of vibrations or sound waves that we can hear these sound waves are formed by objects
Answer:
Sound wave consists to vibrating particles.These knock into other particles causing them to vibrate,and so the sound can travel away from the source.You can hear sound because the vibration in the air cause your ear drums to vibrate this vibration is converted into signals which travel down a nerve to your brain.

How does the interference of sound waves make sounds louder or softer?
Answer:
Changing the amplitude of a sound wave changes its loudness or intensity.
Explanation:
Constructive interference is what can make a sound louder, destructive interference will make a sound quieter. Two waves that add together may have different frequencies.
Why are you able to observe the Doppler Effect with sound waves on Earth but not light waves?

Select the correct answer. Which feature of a wave determines its color in the visible spectrum? A. Amplitude B. Composition C. Temperature D. Wavelength.
Answer:
D. Wavelength
Explanation:
Explanation: the colour of visible light depends on the wavelength of the wave. The visible light spectrum goes approximately from wavelength of 380 nm (corresponding to violet light) to 750 nm (corresponding to red light), and the different colours in between correspond to different wavelengths.

An empty gas balloon has a mass of 500 kg. The balloon is filled with 3000m^3 of helium gas, at standard temperature and pressure (STP). If the densities of air and helium, at STP are 1.3kgm ^ - 3 and 0.18 kgm^ -3 respectively. Calculate the resultant force acting on the balloon. [g = 10N / Kg]
The resultant force acting on the balloon is 10,400 N.
Resultant force acting on the balloonThe resultant force acting on the balloon is calculated by applying Newton's second law of motion as follows;
F = ma
where;
m is massa is accelerationMass of the helium gas = density x volume
= 0.18 x 3000
= 540 kg
Total mass of the balloon = 500 kg + 540 kg = 1,040 kg
Resultant force = mg
Resultant force = 1040 x 10 = 10,400 N

What is the role of greenhouse gases, movement of
energy around earth?
Explanation:
With the natural greenhouse effect, the energy budget is balanced as thermal radiation is re-radiated towards the ground, trapping thermal energy and warming the Earth.Energy from the sun heats Earth's surface, warms the atmosphere, provides energy for photosynthesis, causes evaporation, drives the weather and water cycles, and powers the ocean currents.If you drop a rock from a great height, about how fast will it be falling after 5 seconds, neglecting air resistance?.
Answer:
v = 49.05 m/s^2

a = gravitational acceleration
t = time taken
Assuming the rock is at rest initially, u becomes zero.
