Answer:

D. Different dish soap

Explanation:

The dependent variable is the variable being tested and measured in an experiment, and is 'dependent' on the independent variable.

When we look at rhe example you gave we can see that the only variable that fan be measured and tested, and is dependent would be the dish soap.

suppose you're outside on a hot date and you moving to the shade of a tree which form of energy transfer are you avoiding?​
katovenus [111]

Answer:

Radiation

Explanation:

A sun transfers energy by radiation. However, there are three different modes of heat energy transfer -

a)  Radiation

b) Conduction

c) Convection

Since sun is a at a very far distance from earth, it cannot transfer its heat energy by conduction as for this mode of heat transfer two bodies need to be in touch with each other.

For convection mode of heat transfer a medium is required but for transfer of sun's energy (which is electromagnetic radiation) no medium is required.

Hence, Sun will transfer energy by radiation only.

Hope This Helps!!! <3

Does pb(no3)2 + Na3(PO4) = Pb3(PO4)2 + Na(NO3) have a precipitate?
ipn [44]

Answer:

Yes, Pb3(PO4)2.

Explanation:

Hello there!

In this case, according to the given balanced chemical reaction, it is possible to use the attached solubility series, it is possible to see that NaNO3 is soluble for the Na^+ and NO3^- ions intercept but insoluble for the Pb^3+ and PO4^2- when intercepting these two. In such a way, we infer that such reaction forms a precipitate of Pb3(PO4)2, lead (II) phosphate.

Regards!

How does black and coloured objects absorb light and convert it into heat?
Nezavi [6.7K]

Answer:

Light energy can be converted into heat energy. A black object absorbs all wavelengths of light and converts them into heat, so the object gets warm. A white object reflects all wavelengths of light, so the light is not converted into heat and the temperature of the object does not increase noticeably.
