HELP FAST!!!!!!!Four beakers have water at 27 °C. A piece of metal is dropped into the water in each beaker. The table below shows the initial temperature of the four metals.
A - 30 degrees C
B - 42 degrees C
C - 25 degrees C
D - 16 degrees C
which metals will transfer heat to the water?
A. Metals A and metals B
B. Metals B and metals C
C. Metals C and metals D
D. Metals B and metals D

Answers

Answer 1
Answer:

Answer

A. Metals A and metals B



Explanation

Heat transfer takes place whenever there is temperature difference. When two bodies of different temperatures are brought together, heat energy will move from one body to the other until equilibrium temperature is reached.

In our case, heat transfer will take place in all four metals.

Metal A will transfer heat to the water since it's temperature is higher than that of water.

Metal B will also transfer heat to the water since it's temperature is higher than that of water.

Metal C will get heat from the water since it's colder than the water.

Metal D will also get heat from the water since it is colder than water.

If you walk across a nylon rug and then touch a large metal object such as a doorknob you may get a spark and a shock. Why does this tend to happen more on dry days than on humid days (Hint: it has to do with the electric dipole of water molecules). Why are you less likely to get a shock if you touch a small metal object, such as a paper clip?

In Act III, Scene 1, who hears these words from Titania?Thou art as wise as thou art beautiful.
A. Puck
B. Oberon
C. Bottom
D. Peaseblossom

Answers

C. Bottom

Titania speaks these words as she is under the enchantment of the magic flower, it makes her fall in love with the first thing she sees. It's comedic because Bottom is also enchanted to have the head of a donkey, so she's claiming that this peasant with a donkey head is both wise and beautiful. The reality being that he is as wise as he is beautiful, in that he is neither beautiful nor wise.

What method of generating electricity doesn't make use of a rotating generator?

Answers

Using fossil fuels to generate electricity doesn't take spinning turbines. Using the force of the wind (wind energy) to generate does contain spinning, though not of generators.

HOPE THIS HELPED

When a covalent or an ionic bond is formed a chemical change has occurred. Which of these is not associated with a chemical change?A) The atoms of the substance produced have been rearranged.
B) The substances produced are identical to the substances that reacted except that they're isomers.
C) The total mass of the reacting substances is the same as the total mass of the substance produced by the reaction.
D) The chemical properties of the substances produced by the reaction are different from those of the reacting substances.

Answers

Answer: B) The substances produced are identical to the substances that reacted except that they're isomers.

Explanation: Chemical change is a change in which atoms of the reactants are rearranged ,thus leading to formation of new products.

The new substances formed are different compounds from the original reactants and thus they have different properties.

2Na(s)+Cl_2(g)\rightarrow 2NaCl(s)

This is an example of chemical reaction in which the bond between chlorine molecule is broken and a new bond between sodium and chlorine gets formed.

NaCl formed is an ionic compound whereas chlorine is a covalent compound and sodium is a metal.

The answer is B). The total mass and the atom numbers of reacts and products are the same in the reaction. But that does not mean the production are identical to the reactants.

How many 176 ohm resistors are connected in series to get a current of 5 a on 220 v battey

Answers

Total resistance = voltage / current = 220 / 5 = 44 ohms .

Even one 176-ohm resistor is too much.  The current through it is 1.25 A,
and more than one of them in series reduces the current even further.

Connecting them in parallel, however . . .

Four resistors of 176-ohms each, in parallel, have a net effective resistance
of 176/4 = 44 ohms ... exactly what you need to do the job.
