Alla [95]4 years ago
6 0

Answer:

All objects that have balanced forces acting on them must be stationary is an example of Newton's first law of motion.

Explanation:

  • Newton's First law of motion is the Law of inertia, that states a body continues to be in state opf rest or state of motion untill an unbalanced force acts on it.
  • So if a body has all balanced forces acting on it then it will continue to remain in state of rest i.e. it will be stationary.
  • The first example describes Newton's third law, that every action has equal and opposite reaction.
  • The second and third example supports Newton's Second Law, the law of momentum which states that the rate of change oif momentum is directly proportional to the force applied on the body and the mass of the body.

calculate the kinetic energy of a dodgeball that has a mass of 2 kg and velocity of 4 m/s after being thrown
cluponka [151]

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

1Neurons are classified in several different ways. From the following statements, select which ones are true.
scoray [572]

Answer:

The correct answer is option D. I, II, III, IV, and V

Explanation:

Neurons are the nerve cells that transmit the information in the form of nerve impulses throughout the body. Neurons are an important part of the body and nervous system as neurons control the movement, any other functions of the body. Classification of neurons is presented on different ways such as structural basis, on the basis of functions, histologically, or on the basis of neurotransmitters used by neurons.

Histological classification - bipolar, unipolar, and multipolar.

Function classifications - excitatory and inhibitory.

structural classification - projection neurons and local interneurons.

All type of classification together makes a robust and very useful description of the neurons.

Distinguish between:<br> Bat and Dove​
Contact [7]

Answer and Explanation:

Bats are mammals of the order Chiroptera. With their forelimbs adapted as wings, they are the only mammals capable of true and sustained flight. Bats are more manoeuvrable than birds, flying with their very long spread-out digits covered with a thin membrane or patagium.

Their wings skeleton have the shape of finger/hands like a human.

Doves are the only family in the order Columbiformes. These are stout-bodied birds with short necks, and short slender bills that in some species feature fleshy ceres. They primarily feed on seeds, fruits, and plants.

EVOLUTION CONNECTION The history of life has been punctuated by several mass extinctions. For example, the impact of a meteorite
blsea [12.9K]

Answer:

Dissaster like meteorite impacted all type of living forms, however, animals are impacted the most and plants are impacted least. It is possible due to ability of plants to prepare their food on their own as they are autotrophic and use photosynthesis. The raw material for preparing these are easily available that are sunlight, CO2 and water.

They are not depende on other for their cellular respiration. The other major reason is that the Plant seeds can remain dormant in unfavorable conditions for many years in the soil. The roots always provide nutrition even the stems get effected.
