*EXTRA PTS* How much weight is needed for a 10 m high ball to achieve 400 J of potential energy?
mafiozo [28]

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.

Zielflug [23.3K]

Answer: The answer is Option F I.e none of this.

Explanation.

The answer suppose to be catabolic and anabolic reactions.

A catabolic reaction is a process where larger particles are broken down into smaller particles and energy is given out or generated.

While An Anabolic reaction is the process of building up of smaller particles to form largest particles and energy is consumed. Both reactions take place during digestion in Animals.

The correct answers to the questions are catabolic and anabolic reactions.

seropon [69]

Answer:

1st law: Law of segregation

Explanation:

Mendel’s First Law: Law of Segregation During each round of meiosis, chromosomes are separated into daughter cells. This means that one half of the genetic material goes to one gamete and the other half goes to the other. Mendel’s first law essentially states that the alleles in one locus segregate into separate gametes.
