a. A lifted parcel of air will be colder (heavier) that the air surrounding it. Because of this fact, the lifted parcel will ten

d to sink back to its original position. b. The rate of adiabatic cooling or warming that occurs in a parcel of air that is unsaturated. c. The level at which a lifted parcel of air becomes saturated, marking the base of a cumuliform cloud d. ​ If a parcel of air expands and cools, or compresses and warms, and there is no interchange of heat with its outside surroundings. e. If rising air cools to its dew-point temperature, condensation results forming a cloud. Because heat added during condensation offsets some of the cooling due to expansion, the air cools at a lower rate. f. The level at which a lifted parcel of air in a conditionally unstable atmosphere becomes warmer (lighter) than its environment and continues to rise freely g. A lifted parcel of air will be warmer (lighter) than the air surrounding it, and thus will continue to rise upward, away from its original position.

Explain how and why energy is important to living things. Your answer to this question will become the claim for your scientific
Leto [7]

Answer:

All living organisms need energy to grow and reproduce, maintain their structures, and respond to their environments. Metabolism is the set of life-sustaining chemical processes that enables organisms transform the chemical energy stored in molecules into energy that can be used for cellular processes.

Which statements accurately describe the shape of Earth’s orbit around the Sun? Check all that apply.
damaskus [11]
<span>The Earth’s orbit is a nearly circular ellipse.
</span><span>The Sun is located at one of the two focal points.</span>

The Earth moves around the Sun in an orbit that is almost but not quite circular. As Kepler proved in the seventeenth century, the orbit is actually an ellipse. A parameter called the eccentricity (e) defines the degree of departure from a circle. A value of e=0 would indicate a circle whereas a value of e=0.9 would indicate a very elongated ellipse. The eccentricity of the Earth's orbit is currently e=0.0167.

20 J of energy was used to
Leto [7]

Answer:

0.3m

Explanation:

Given parameters;

Elastic energy  = 20J

Spring constant = 445N/m

Unknown

Final extension of the spring  = ?

Solution:

The elastic potential energy of a stretched spring can be determined using the expression below;

         

           EP  = \frac{1}{2} k e²

k is the spring constant

e is the extension

  Insert the parameters and solve;

          20  = \frac{1}{2} x 445 x e²

        multiply those sides by 2;

         2(20) = 445e²

            40  = 445e²

              e² = \frac{40}{445}   = 0.09

              e  = √0.09 = 0.3m

Which of these statements best proves that electromagnetic forces are weaker than strong nuclear forces? Neutrons do not repel o
MAVERICK [17]
Protons do not move out of the nucleus of atoms although they repel each other.

Remember that protons are particles with positive charge and they held together in the nucleus of the atom which is a tiny tiny region. As you know, like charges repel each other, which means that the protons exert a repulsion force.

There is a person who throws a coin vertically downward with an initial speed of 11.8 m/s from the roof of a building, 34.0 m ab
omeli [17]

Answer:

Time taken by the coin to reach the ground is 1.69 s

Given:

Initial speed, v = 11.8 m/s

Height of the building, h = 34.0 m

Solution:

Now, from the third eqn of motion:

v'^{2} = v^{2} + 2gh

v'^{2} = 11.8^{2} + 2\times 9.8\times 34.0 = 805.64

v' = \sqrt{805.64} = 28.38 m/s

Now, time taken by the coin to reach the ground is given by eqn (1):

v' = v + gt

t = \frac{v' - v}{g} = \frac{28.38 - 11.8}{9.8} = 1.69 s
