Activity: classifying muscle types
Use the following story to classify the different muscle types. Use a coloured
pen or highlighter to underline or highlight the actions in the story whichrequire the different types of muscles
Suggested colours to use: Pink = Cardiac Muslces; Blue =Voluntary ; Yellow =
Involuntary
Then draw each structure in the space provided

6 a.m on a Monday morning Tsholo’s alarm goes off.
She jumps out of bed and walks to the toilet to relieve her bladder. Tsholo is

Interesting facts – skeleton
A baby is born with more bones (360 bones) than an adult (average 206 bones).
Bones making up the skull and the spine fuse together as the body grows makingit less.
The femur/thigh bone is the largest in your body. The femur is approximately one
quarter of a person’s overall height.
Strengthen your skeleton by drinking milk and eating leafy greens (such as
brussels sprouts and kale). They contain calcium which keeps bones healthy andstrong.
A broken bone produces many new cells to rebuild the bone. These cells cover
both ends of the broken part of the bone and close up the break.
Your bones are alive! In your body bones have their own nerves and blood
vessels.
Your bone is 50% water and 50% solid material
You have 14 bones are in your face.
There are 8 bones in each of your wrists
You have 23 bones in each foot ( this includes the ankle)
Your skull is made up of fused bones which acts like a hard protective helmet
for your brain.

A golfer on a fairway is 70 m away from the green, which sits below the level of the fairway by 20 m. If the golfer hits the ball at an angle of 40° with an initial speed of 20 m/s, how close to the green does she come?
A mouse of mass 200 g falls 100 m down a vertical mine shaft and lands at the bottom with a speed of 8.0 m/s. During its fall, how much work is done on the mouse by air resistance

you have been hired as an espert witness in a court case involving an automobile accident. the accident involved car A of mass 1500kg which crashed into stationary car B of mass 1100kg. the driver of car A applied his brakes 15 m before he skidded and crashed into car B. after the collision, car A s
can someone explain to me, an ignorant high school student, why the trend of the graph doesn't follow the fact that the higher frequency a sound wave is, the more power it is, hence, making me think the phons output would follow this general trend?
Nevermind i just realied that the graph is the phons output for a person with normal hearing and not just the phons output of the sound waves power, I should read the entire thing next time
Joseph
Follow up question, does anyone know where I can find a graph that accuretly depicts the actual relative "power" output of sound over its frequency instead of just humans hearing

A string is 3.00 m long with a mass of 5.00 g. The string is held taut with a tension of 500.00 N applied to the string. A pulse is sent down the string. How long does it take the pulse to travel the 3.00 m of the string?
