The ratio of the distance moved by the point at which the effort is applied in a simple machine to the distance moved by the point at which the load is applied, in the same time. In the case of an ideal (frictionless and weightless) machine, velocity ratio = mechanical advantage. Velocity ratio is sometimes called distance ratio.
Answer:
t = 6 [s]
Explanation:
In order to solve this problem we must first use this equation of kinematics.
where:
Vf = final velocity = 0 (the car comes to rest)
Vo = initial velocity = 72 [km/h]
a = acceleration [m/s²]
x = distance = 60 [m]
First we must convert the velocity from kilometers per hour to meters per second.
Now using this other equation of kinematics.
0 = 20-3.33*t
t = 6[s]
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.
9. Calcaneodynia
Calcane/o - refers to the heel bone
/dynia - pertains to pain
Calcaneodynia is a condition where there is pain when weight is put on the heel of the foot.
10. Metacarpectomy
Metacarp(o)/ - refers to bones in the hand (Metacarpals)
/ectomy - excision or removal.
Metacarpectomy is the surgical excision of one or more metacarpals.
Answer:
The role of a commutator in a electric generator is a rotary switch (in certain types of electrical generators that periodically reverse the current direction between the rotor and the external circuit by that reversing it in the current direction teb rotating windings all half turn a force called torque is produced)
Answer:
677 m
Explanation:
Using the definition of the sine of an angle, we can write
sin 14.1 = (height of mountain) / (slope length of mountain)
sin 14.1 = H / (2780 m) ---> H = (2780 m) x sin 14.1
= 677 m
