Gwar [14]

Answer:

The planets follow these orbit  paths as they travel around the Sun. The Sun’s gravity  

makes the planets move in this way. It pulls on the planets, keeping them in motion in their orbit.

Modeling is a way to see ideas or have a  particular idea or

concept.

 Models do have some lines .

 Often a model is made with certain things.

 A model of the solar system may contain all of the planets and the Sun, but it may not include the planets’

individual moons or every planit  and rock in the solar system.

Explanation: if you think about it and and look at pics it is easy

hope this helps

How is a battery and a banana the same when considering energy?
emmainna [20.7K]

A battery and a banana are the same when considering energy:

A battery when connected to a device produces electro-chemical reactions and contains one or more cells. The same thing can be tried out with fruits also. There are many fruits which can be taken into account. A lemon shows less amount of voltage when seen through a multimeter rather than a banana which shows a higher voltage. This was because of the acid present in the a fully ripped banana. The acid is called ascorbic acid. This acid has a higher pH level than compared to the pH of the citric acid found in lemon.  

This shows that a banana plant is not so expensive and reliable for the production of renewable energy and a battery is also inexpensive, reliable and stable.

What are deltaTb and deltaTf for an aqueous solution that is 1.5g nacl in 0.250kg h2o? Given Kb=0.51 C/m and kr=1.86 C/m
bulgar [2K]

Answer:

T_f for given question is 2.79 and T_b is 0.52

\Delta T_b = I \times K_b \times m {i- vant hoff’s constant ; Kb- constant ; m molarity }

M = no. of moles of the solute present in one kg of solution

Let the weight of amount of solute be “w” and its molecular mass be “M”

Let the mass of the solvent in the given question be “x”

\Delta T_b = I \times K_b \times (w/M)/ x

\Delta T_b = I \times K_b \times w/Mx

\Delta T_b = 1 \times 0.51 \times1.5/(0.250 \times 58.44) = 0.052

\Delta T_f = M \times K_f = 1.86 \times 1.5 = 2.79
