Answer:
The answer is C...............
Answer:
,Mass of the Body = 10 kg.
Height = 10 m.
Acceleration due to gravity = 9.8 m/s².
Using the Formula,Potential Energy = mgh
= 10 × 9.8 × 10 = 980 J.
(b). Now, By the law of the conservation of the Energy, Total amount of the energy of the system remains constant.
∴ Kinetic Energy before the body reaches the ground is equal to the Potential Energy at the height of 10 m.
∴ Kinetic Energy = 980 J.
(c). Kinetic Energy = 980 J.
Mass of the ball = 10 kg.
∵ K.E. = 1/2 × mv²
∴ 980 = 1/2 × 10 × v²
∴ v² = 980/5
⇒ v² = 196
∴ v = 14 m/s.
Answer:
Secondary
Explanation:
There are several levels of prevention. You might confuse this with primary prevention. Primary prevention is preventing infection, so it has to be done before the patient caught the disease.
The needle-exchange program aims to reduce the spread of blood-borne disease(HIV, hepatitis, etc) from the multiple usages of the same needle. Since the disease already exists, this will be secondary prevention.
<h2>Simple contusion </h2>
Explanation:
Simple contusion in eye
- Simple contusion is also known as bruise or commonly known as black eye which is used to describe the discoloration that occurs around an eye after a trauma to the eye or surrounding tissues
- It is caused by broken blood vessels under the surface of the skin is typically accompanied by swelling
- A serious condition that can accompany a black eye is bleeding inside the eye, in the space between the back side of the cornea and the front of the iris which is called hyphema
Scleral hemorrhage
- Scleral hemorrhage also known as subconjunctival hemorrhage
- When small and delicate blood vessels break beneath the tissue covering the white of the eye (conjunctiva), resulting eye redness then this condition is known as subconjunctival hemorrhage
- A subconjunctival hemorrhage usually is benign, causing no vision problems or significant eye discomfort despite its conspicuous appearance
- But eye redness also can be a sign of other types of potentially serious eye conditions
