Answer:

A space station orbiting

Explanation:

As we know that kinetic energy associated with the motion of particle and it is given as

m= Mass

V =Velocity

KE=\dfrac{1}{2}mV^2

If V= 0 ,means velocity of particle is zero then it kinetic energy will be zero.

A)

At ATP molecule does not have any movement that is why it kinetic energy is zero.

B)

A space station have velocity that is why it have kinetic energy.

C)

A rock on mountain ledge do not have kinetic energy .Because it is not moving.

D)

When person sitting it means that it dies not have any motion that is why it does not have kinetic energy.

A plane flies 1800 miles in 9 ​hours, with a tailwind all the way. the return trip on the same​ route, now with a​ headwind, tak
Fittoniya [83]

Initially its moving with tail wind so here the speed of wind will support the motion of the plane

so we can say

V_{plane} + v_{wind} = \frac{distance}{time}

V_{plane} + v_{wind} = \frac{1800}{9}

V_{plane} + v_{wind} = 200 mph

now when its moving with head wind we can say that wind is opposite to the motion of the plane

V_{plane} - v_{wind} = \frac{distance}{time}

V_{plane} - v_{wind} = \frac{1800}{12}

V_{plane} - v_{wind} = 150mph

now by using above two equations we can find speed of palne as well as speed of wind

V_{plane} = 175 mph

v_{wind} = 25 mph

Reading the temperature of a solution by using a thermometer is an example of a(n) ________.
blsea [12.9K]

Answer:

B. Observation

Explanation:

Using a thermometer to read the temperature of a solution is tantamount to the making an observation.

Observation are recorded using our senses of sight, taste, earing, feeling etc or by the use of instrument.

  • Through observation, data is usually collected to make inferences about an experiment.
  • An observation leads to the formulation of a hypothesis which is scientific guess that leads to experimental designs.
  • Conclusions are drawn from the information of data obtained from an experiment.

The following chart provides the pH of some common foods. How many would be considered basic?
Yuri [45]

The ones with pH greater than 7

Explanation:

A pH scale is a scale for expressing the level of acidity or alkalinity of aqueous solutions.

This scale is called a pH or pOH scale. The pH is the common one.

pH of a solution is the negative logarithm to base 10 o the hydrogen ion concentration of the solution.

  • The scale ranges from 1 through 14.
  • An acidic solution has a pH value less than 7. Neutral solutions have pH of 7 and basic solutions have pH greater than 7.
