calculate the kinetic energy of a dodgeball that has a mass of 2 kg and velocity of 4 m/s after being thrown

Answers

Answer:

Kinetic energy of dodgeball = 16 kg-m/s

Explanation:

Given:

Mass of dodgeball = 2 kg

Velocity of dodgeball = 4 m/s

Find:

Kinetic energy of dodgeball

Computation:

Kinetic energy = (1/2)(m)(v²)

Kinetic energy of dodgeball = (1/2)(Mass of dodgeball)(Velocity of dodgeball²)

Kinetic energy of dodgeball = (1/2)(2)(4²)

Kinetic energy of dodgeball = (1/2)(2)(16)

Kinetic energy of dodgeball = (32/2)

Kinetic energy of dodgeball = 16 kg-m/s

Answers

Answer:

D

Explanation:

Develop technology and resources capable of sending the general population into space on a regular basis.

What is Developmental Technology?

L. Mumford presented an intriguing theory regarding the origin of technology, contending that biotechnology gave rise to both machine and gun technology.

Technique is derived from the characteristics of how people behave and, in its earliest forms, is directly tied to the origin of man. It was first and foremost life-focused, and only afterwards was it work-focused.

According to L. Mumford, technique with a focus on power and output developed much later. He held that the impersonal aspects of human adaptability to the outside world are what give origin to technology.

Therefore, Develop technology and resources capable of sending the general population into space on a regular basis.

Infant Respiratory Distress Syndrome occurs when there is a lack of surfactant
produced. THis is common in premature infants.
In healthy individuals, friction is a major factor affecting pulmonary ventilation

Answers

Answer: Infant Respiratory Distress Syndrome occurs when there is a lack of surfactant  produced. This is common in premature infants.

Explanation:

Infant Respiratory Distress Syndrome (RDS) occurs in new born infants whose lungs are unable to produce the enough surfactant to keep their lungs expanded which would enable them to breathe properly after delivery.

It is most common in premature infants because surfactant is produced in the third trimester of pregnancy so premature infants might not get the chance to produce enough before the are delivered. RDS needs to be treated as soon as possible or else a baby could suffer damage to the brain and other vital organs.

The service box is an area on the court that 1 point the person serving must stand in. the ball must land in to be a playable serve. the person returning the serve must be standing in before a server can serve ​

Answers

Answer:

Both players on the serving doubles team have the opportunity to serve and score points until they commit a fault *(except for the first service sequence of each new game).

The first serve of each side-out is made from the right-hand court.

If a point is scored, the server switches sides and the server initiates the next serve from the left-hand court.

As subsequent points are scored, the server continues switching back and forth until a fault is committed and the first server loses the serve.

When the first server loses the serve the partner then serves from their correct side of the court (except for the first service sequence of the game*).

The second server continues serving until his team commits a fault and loses the serve to the opposing team.

Once the service goes to the opposition (at side out), the first serve is from the right-hand court and both players on that team have the opportunity to serve and score points until their team commits two faults.

In singles the server serves from the right-hand court when his or her score is even and from the left when the score is odd.
