Answer:

However, compared to other stars, our Sun is only a medium-sized star, meaning that some stars are much larger than the Sun and some are much smaller. The Sun looks bigger than other stars because it is so much closer to the Earth. The further away an object is, the smaller it appears, even if it is very big.

A real spring does not oscillate forever. Instead, it eventually comes to a stop. Does this violate the law of conservation of e

ss7ja [257]

It does not violate the law of conservation of energy. The oscillation stops when the energy is lost and the energy is lost because it becomes heat that is created by the air resistance and many other forces found in the surrounding of the oscillating spring.

Answer:

1.F = 256 N

2.a = 8 m/s/s

By looking at the given information, you know force, and an acceleration. Therefore you have enough information to use the first formula.

F = ma

256 N = m * 8 m/s/s

m = 256 N/8 m/s/s

m = 32 Kg

In a cyclic process, a gas performs 123 J of work on its surroundings per cycle. What amount of heat, if any, transfers into or

Aleks04 [339]

Answer:

123 J transfer into the gas

Explanation:

Here we know that 123 J work is done by the gas on its surrounding

So here gas is doing work against external forces

Now for cyclic process we know that

$\Delta U = 0$

so from 1st law of thermodynamics we have

$dQ = W + \Delta U$

$dQ = W$

so work done is same as the heat supplied to the system

So correct answer is

123 J transfer into the gas

The energy necessary to enable a reaction to occur is called the activation energy.

12345 [234]

True. In order for a chemical reaction between elements/compounds, the atoms within the chemicals must have sufficient energy in order to be able create a reaction.

A sculptor has asked you to help electroplate gold onto a brass statue. You know that the charge carriers in the ionic solution

scZoUnD [109]

Answer:

ampere = 15.95 mA

Explanation:

given data

deposit gold = 0.560 g

time = 4.70 hour = 16920 s

solution

we get here moles of gold that is

moles of gold = 0.560 g ÷ 196.967 g/mol

moles of gold = 0.0028

moles of gold = 0.0028 ( 1 Faraday / 1 mol )

moles of gold = 0.0028 Faradays

moles of gold = 0.0028 Faradays × 96500 Coulom/ faraday

moles of gold = 270.2 coulombs

and we get here ampere that is

ampere = $\frac{270.2}{16920}$

ampere = 0.01596 A

ampere = 15.95 mA
