n the sciences, the “tools” for measuring the volumes of liquids are generally made from glass, plastic or occasionally metal, although professionals referred to all of them as “glassware.” Scientists, and chemists in particular, have a variety of glassware at their disposal for measuring volumes. The particular piece of glassware chosen in any situation will depend primarily upon two factors: the required volume and the accuracy required for the measurement.

Explanation:

Answer:

λ  = 3.0 × 10⁻¹² m

Explanation:

Speed of Light = Wavelength × frequency

c = λν

Step 1: Define

c = 3.0 × 10⁸ m/s

λ = unknown

ν = 1 × 10²⁰ Hz

Step 2: Substitute and Evaluate for λ

3.0 × 10⁸ m/s = λ · 1 × 10²⁰ Hz

λ = 3.0 × 10⁸ m/s ÷ 1 × 10²⁰ Hz

λ  = 3.0 × 10⁻¹² m

Answer: The circulatory system.

Explanation: The circulatory system, which is part of the "cardiovascular" system, is one of the eleven organ systems of the human body. Its main function is to transport nutrients to cells and wastes from cells (Figure 3.4. 1). This system consists of the heart, blood, and blood vessels.

The blood cells carry nutrients from food to the rest of the cells in the body.

The human circulatory system moves important nutrients and minerals throughout the body and metabolic waste products out from the body. The human circulatory system contains blood, blood vessels, heart, and lymph.

The human circulatory system provides essential nutrients, minerals, oxygen, and hormones to different parts of the body and is responsible for collecting toxins from the cells and tissues to be purified or eliminated from the body.

The human circulatory system contains a wide network of blood vessels. These constitute arteries, veins, and capillaries. The primary function of blood vessels is to transport nutrients and oxygenated blood to all parts of the body.

The Circulatory system helps in sustaining all the organ systems and transports blood, nutrients, oxygen, and hormones throughout the body. It secures cells from pathogens and acts as an interface for cell to cell interaction.

[Rn]7s25f14

Explanation:

[tex][Rn]5f^{14}7s^2[/tex] is the electron configuration for nobelium (No).

Explanation:

Given:

The element nobelium.

To find:

The electronic configuration of nobelium

Solution:

The atomic number of nobelium is 102.

The number of protons = Atomic number = 102

The number of electrons = Number of protons = 102

There are 102 electrons in atom nobelium and they will be filled according to the Aufbau rule that the electron will be filled in a subshell with lower orbital energy.

The electronic configuration of nobelium :

[tex][No]=1s^22s^22p^63s^23p^63d^{10}4s^24p^64d^{10}5s^25p^64f^{14}5d^{10}6s^26p^65f^{14}7s^2[/tex]

The volume occupied by 0.34 moles of Helium Gas is 7.62 L.

Any gas from the  group of rare gases that include helium, neon, argon, krypton, xenon, and usually radon and that exhibit great stability and extremely low reaction rates. — called also inert gas.

They have properties tending to an ideal gas.

It is asked that what volume will be occupied by  0.34 moles Helium Gas

The ideal gas equation is written as

PV = nRT

At STP , T = 273 K

P= 1atm

R = 0.0821 L(atm) mol⁻¹K⁻¹

Substituting the values

1 * V = 0.34 * 0.0821 * 273

V = 7.62 L

Therefore the volume occupied by 0.34 moles of Helium Gas is 7.62 L.

you had the right idea with your Significant figures however, when we divide we see that it requires 2 significant figures as our least amount. this is because when looking at our division, 62 has 2 sig. fig. while 5.35 has a total 3. when looking at your answer we see that you had a total of 3 sig. figures. so in actuakity you had to round up to 12 and not to the tenths because the decimal makes .6 count as your third sig fig.

Explanation:

Answer:

The area of the block is 150 cm

Explanation:

Answer:

See explanation below

Explanation:

Let's recall what's the law of acceleration.

First of all, the acceleration is a vector that has the change of velocity in function of the time.

Now, the law of acceleration is related to Newton's Second law which states that an object will move only if there are forces around it. In other words, the following expression:

F = m . a

Now, in this case, we know that the acceleration of an object is affected by a force always. So, if an object stand still, it will not move unless you push it or pull it to move, and the acceleration will speed up or down depending of the force it was exerted.

According to this, the law of acceleration can be applied here:

1. A bike going down a hill. Of course, because, let's suppose you let a bike alone go down on a hill, you will see that the speed of the bike will be faster as time goes by. This is because the force acting here is the weight of the bike and gravity.

2. Dropping a ball from a building. In this case, you drop a ball from a high floor on a building, it will happen the same thing as the bike. It will go faster because of gravity.

3. Putting the break on a car. Now in this case it's easy because you only need to know that when you put the brakes, the speed of the car will go down, but also the acceleration. So there's no need of a further explanation of this.
