Answer:
W = 3.12 J
Explanation:
Given the volume is 1.50*10^-3 m^3 and the coefficient of volume for aluminum is β = 69*10^-6 (°C)^-1. The temperature rises from 22°C to 320°C. The difference in temperature is 320 - 22 = 298°C, so ΔT = 298°C. To reiterate our known values we have:
β = 69*10^-6 (°C)^-1 V = 1.50*10^-3 m^3 ΔT = 298°C
So we can plug into the thermal expansion equation to find ΔV which is how much the volume expanded (I'll use d instead of Δ because of format):
So ΔV = 3.0843*10^-5 m^3
Now we have ΔV, next we have to solve for the work done by thermal expansion. The air pressure is 1.01 * 10^5 Pa
To get work, multiply the air pressure and the volume change.
W = 3.12 J

Answer:
The angular acceleration of the centrifuge is -231.74 rad/s².
Explanation:
Given that,
Angular speed = 3500 rev/min = 366 rad/s
We need to calculate the angular displacement
Using formula of angular displacement
Put the value into the formula
We need to calculate the angular acceleration
Using equation of motion
Hence, The angular acceleration of the centrifuge is -231.74 rad/s².
1. Tendinitis
Tendin/ - refers to the tendon
/itis - means inflammation
Tendinitis is the inflammation of the tendon. It is usually caused by repetitive impact on the area that is affected and/or direct injury.
2. Osteoporosis
Oste/o/ - refers to bones
/porosis - means porous or a condition of pores.
Osteoporosis literally means porous bones. It is a disease where bones become fragile or weak because of the decreased bone density. It increases the risk of fracture.
3. Arthritis
Arthr(o)/ - refers to joints
-itis - means inflammation
Arthritis is the inflammation of a joint or joints. Joints affected develop stiffness, pain, redness, and warmth. It can be caused by infection, metabolic problems and or constitutional causes.
4. Osteocytes
Osteo/ - refers to the bone
cyte/s - Means cells.
Osteocytes are also known as bone cells. It is the type of cell that can be found in bones that are fully formed.
5. Costochondritis
Cost(o)/ - refers to the ribs.
chondr(o)/ - refers to cartilage
-itis - means inflammation
Costochondritis is the inflammation of the cartilage connected to the sternum and the ribs. It is also known as chest wall pain and the pain resembles the pain felt during a heart attack.
6. Lordosis
Lord(o)/ -means curve/swayback
-osis - pertains to an abnormal condition
Lordosis is also known as swayback. This occurs when the spine curve is too far inward in the lumbar spine.
7. Myocytes
Myo/ -refers to the muscles
cyte/s - means cells.
Myocytes are also known as muscle cells. They are the type of cells that make up tissues of the muscles. They are long and tubular in appearance.
8. Myelocyte
Myelo/ -refers to the bone marrow or the spinal cord.
/cyte - means cell.
Myelocytes are bone marrow cells. They are motile and produce blood granulocytes (these are a kind of white blood cells). They occur in the bone marrow.
