MaRussiya [10]2 years ago
5 0

Answer:

A - Sublimation

B - Evaporation

C - Melting

Explanation:

The state of change present in A is Sublimation. Dry Ice is the most common example of Sublimation of everyday life

The state of change present in B is evaporation. Boiling water into water vapor is something that anyone can see.

The state of change present in C is called Melting. Think of Ice melting into a pool of water as the ice heats up.

I know how the voltage increasing/not enough/stays the same and how long the battery lasts with series and parallel connections.
kirill [66]

Answer:

It comes out the positive side of the battery and goes in to the negative side of the battery

Explanation:

There are already electrons in wires in a circuit before you add the battery. By adding the battery, you're giving the electrons the energy it needs to move along the circuit.

In a series circuit, the circuit is one continuous loop so there is only one path for the electrons to go - out of the positive side of the battery and around the circuit then goes back into the negative side of the battery.

However, with a parallel circuit, there are two or more ways the electrons can go so they take the path of least resistance. The electrons still go out the positive side of a battery but along the circuit, the electrons will go through the path of least resistance ( I tend to think of it like a net with holes in it - the lower the resistance the bigger the holes for the electrons to go through so more can fit in a set amount of time ) but the electrons still go out of the positive side and in through the negative

A 1000 N object is pulled along a level surface with a horizontal force of 200 N. The object moves with a constant velocity of 2
krek1111 [17]

0.2 is the value of coefficient of friction (k)

F=kN

F=horizontal force

n=Normal Force

k=coefficient of friction

k=F/N

k=200/1000

k=0.2

The ratio of the normal force pushing two surfaces together to the frictional force preventing motion between them is known as the friction coefficient. Usually, the Greek letter mu is used to indicate it .N is the normal force, and F is the frictional force, hence F = N/N.

Due to the fact that both F and N are measured in units of force, the coefficient of friction has no dimensions (such as newtons or pounds). The coefficient of friction can have a variety of values for both static and dynamic friction. Static friction occurs when an object encounters friction that resists any applied force, keeping the object at rest until the static frictional force is released. In kinetic friction, the frictional force resists the motion of the object.

Which metal would cause the greatest increase in the temperature of the water in the calorimeter: the one with the highest speci
masha68 [24]
<h3><u>Answer;</u></h3>

the one with the highest specific heat

<h3><u>Explanation;</u></h3>
  • The specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius.
  • The specific heat of water is 1 calorie/gram °C or 4.186 joule/gram °C which is higher than any other common substance.
  • <em><u>A metal with the highest specific heat will cause the greatest increase in temperature of water in a calorimeter because the metal would hold more heat, and then transfer the greater quantity of heat to the water.</u></em>
