Convection is the transfer of heat through a fluid

Conduction is the heat or electric current from one substance to another

Radiation is energy that radiated or transmitted

Ex: Convection- A pot of water is being boiled- the heat is being transferred to to the water

Ex2: Conduction- I have a plate filled with hot food- the heat from the food is being transferred to the plate, making the plate hot as well.

Ex3: Radiation- There is a dog by the fire place, the dog is being warmed- the heat from the fire is being transferred over to the dog

Hope this will help you with your homework :)

A spherical drop of water carrying a charge of 43 pC has a potential of 540 V at its surface (with V = 0 at infinity). (a) What

almond37 [142]

Explanation:

Given that,

Charge on a spherical drop of water is 43 pC

The potential at its surface is 540 V

(a) The electric potential on the surface is given by :

$V=\dfrac{kq}{r}$

r is the radius of the drop

$r=\dfrac{kq}{V}\\\\r=\dfrac{9\times 10^9\times 43\times 10^{-12}}{540}\\\\r=7.17\times 10^{-4}\ m$

(b) Let R is the radius of the spherical drop, when two such drops of the same charge and radius combine to form a single spherical drop. ATQ,

$\dfrac{4}{3}\pi r^3+\dfrac{4}{3}\pi r^3=\dfrac{4}{3}\pi R^3\\\\2r^3=R^3\\\\R=2^{1/3} r$

Now the charge on the new drop is 2q. New potential is given by :

$V=\dfrac{9\times 10^9\times 43\times 10^{-12}\times 2}{2^{1/3}\times 7.17\times 10^{-4}}\\\\V=856.79\ V$

Hence, the radius of the drop is $7.17\times 10^{-4}\ m$ and the potential at the surface of the new drop is 856.79 V.

the first law of thermodynamics states that (triangle)E= Q-W. is this also a statement of the principle of conservation energy

Verdich [7]

Yes, the first law of thermodynamics was created using the law of conservation of energy that is applied in a thermodynamic systems.the first law of thermodynamics is the change in internal energy of an isolated system is equal to the amount of heat (Q) added to the system minus the work (w) done by the system to the surroundings . while the law of conservation of energy states that in an isolated system that energy is constant, and energy can change its form but it cannot be created or destroyed.

If constants aren't given in an experiment, what can be constant in the experiment?

mario62 [17]

Answer:

Anything in an experiment that remains unchanged.

Explanation:

An example could be the temperature of the laboratory room. If there is something that has an effect on an experiment that is not variable, it is a constant. Another constant could be, say, if you were doing calculations with the same amount and kind of fluid throughout the experiment, then that fluid would also be a constant.

How long would it take to reach Jupiter? in years, months, days, hours?

Vlada [557]

Because both planets (Earth and Jupiter) travel in elliptical path around the Sun, Jupiter's distance from Earth is constantly changing. However, the Galileo spacecraft launched for Jupiter in October 1989, and it took just over 6 years to get to the planet.
In 2011, Juno was launched as well, and it is estimated that it will take 5 years to get to Jupiter.
