Answer:
<em>1. c. Same in both</em>
<em>2. a. Case 1</em>
<em></em>
Explanation:
1. The balls are identical in all sense, which means that if they are dropped from the same height, they should posses the same kinetic energy just before they collide with either the concrete floor or the stretchy rubber. Also, since they reach the same height when they bounced of the concrete floor or the piece of stretchy rubber, it means that they posses the same amount of kinetic energy at this point. Since their kinetic energy at these two points are the same, and they have the same masses, then this means that their momenta at these two instances will also be equal. Since all these is true, then the change in the momentum of the balls between the instance just before hitting the concrete floor or the stretchy rubber material and the instant the ball just leave the floor or the stretchy material is the same for both.
2. The ball that falls on the concrete will experience the greatest force, since the time of impact is small, when compared to the time spent by the other ball in contact with the stretchy rubber material; which will stretch, thereby extending the time spent in contact between them.
Answer:Plant Cells have big Vacouls whereas Animal cell have small Vacouls. Plant Cell have cell wall and cell membranes but animal cell has got cell membranes only. Plants cell has Chloroplast and whereas in animal cell it's absent. Plastids absent in animal cell and present in plant cell.
Explanation:
Answer:
1.23 m/s
Explanation:
p=mv
57.2 = 46.5v
v= 57.2/46.5
v= 1.23
If you want to verify your answer, just insert the value of v in the equation.
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.
