Answer: The correct answer is solution.

Explanation:

A solution is a homogeneous mixture of two or more substance. The substance which is dissolved in another substance is called solute. The solvent is the liquid which dissolves in solid, liquid and gas.

For example, salt is put into water. It gets dissolved completely. Here, salt is solute and water is solvent.

In the given problem, a solid is stirred into a liquid and gets dissolve. A solid is dissolved into liquid.

Therefore, the type of mixture forms solution.

The type of mixture that is formed when a solid is stirred into a liquid and dissolves is called suspension. The particles involved or being mixed in this type of mixture is large enough that can be seen by the naked eye without the aid of any device. A suspension mixture has a heterogeneous mixture.

2. Sally put her mug of coffee on the table. The mug has a mass of 1 kg. if the pressure

egoroff_w [7]

We have,

The mass of sally's mug is 1 kg
The pressure appliedby the mug is 1100 pascal.

We know that,

Pressure = Force/Area

As, we already have the value of pressure, let's calculate that of force now;

F = ma
F = 1 × 9.8 { Acceleration due to gravity, let's round off it to 10}
F = 10 N

Just put all the values in the formula now;

P = F/A
1100 = 10 / A
1100/10 = A
110 m² = A

As, it is already mention that we need to find the radius of the mug, it is obviously a circular base.

We know that,

Surface area = Circumference

So, let's solve it;

Circumference = 2πr
110 = 2 × 22/7 × r
110 × 7/2 × 22 = r
5 × 7 = r
35 cm = r

Thus, the radius of the circle is 35 cm.

If an object is travelling faster than its own sound waves, which of the following is created?

Andrej [43]

Answer:

Explanation:

When an object travels faster than the speed of sound, a sonic boom is created. A ring of pressure waves (probably why wave destruction and pressure cooker are options lol) are created, which is why when you see a jet make a sonic boom there looks like a ring shaped cloud behind it. Hope this helps! For further confirmation/information, just look up sonic boom science (or else you will get sonic boom the video game)
