Answer:
Explanation:
v = ω R
v is linear speed and ω is angular speed
ω = v / R
a ) Inner radius = 25 x 10⁻³ m
speed v = 1.25 m/s
ω = 1.25 / (25 x 10⁻³ )
= .05 x 10⁻³
= 5 x 10⁻⁵ rad / s
outer radius = 58 x 10⁻³ m
speed v = 1.25 m/s
ω = 1.25 / (58 x 10⁻³ )
= .0215 x 10⁻³
= 2.15 x 10⁻⁵ rad / s
b )
linear constant speed v = 1.25 m /s
time = 74 min = 74 x 60 s
distance tracked = speed x time
= 1.25 x 74 x 60
= 5550 m
c ) time given
= 74 min = 74 x 60 s
angular acceleration
= ( 2.15 - 5 ) x 10⁻⁵ / (74 x 60 )
= - 6.42 x 10⁻⁹ rad / s²
He did sadly can’t believe it T-T
The answer is Compressional.
Compression is a stress that pushes and squeezes rocks together. This causes the rock to bend or fracture.
Tension is a stress that pulls rocks apart. Shear stress occurs when the rocks are moving parallel but opposite of each other pushing rocks at different directions. Gravitational stress is stress induced by gravity.
First of all I can't write the story for you but I can help you brain Storm.
1. Choose the character you know the most about If you know Super Hero's,Cartoons etc. use what you know then it won't look like you're randomly throwing things in.
2. Figure out witch part of the brain you want to talk about, the facts you want to put in there, and organize your facts.
3. Put it in little kid language, use small words and not BIG words 5-6 year old's have a good Vocabulary but it is better to use small words.
Ok hope you have fun writing this story!
