Answers

Answer:

Only the third option has the same number of each size and color circles on either side of the arrow.

Explanation:

I believe it represents the dissolution of two molecules of hydrogen peroxide into two water molecules and an oxygen gas molecule.

The first one balances oxygen but changes sulfur with either carbon or nitrogen

The second one needs 5 oxygen gas pairs instead of a single one on the left to balance the right side. Represents oxidation of a propane molecule if given enough oxygen.

The fourth one has an extra nitrogen on the left side. The hydrogen is balanced. Making amonia.

A cyclist rode the first 30​-mile portion of his workout at a constant speed. For the 22​-mile cooldown portion of his​ workout, he reduced his speed by 4 miles per hour. Each portion of the workout took the same time. Find the​ cyclist's speed during the first portion and find his speed during the cooldown portion.

Answers

Answer:

The cyclist rode the first 26​-mile portion of his workout at a constant speed.

Time = distance/speed

Time taken to ride through the first portion is

26/x

For the 18​-mile cool down portion of his​ workout, he reduced his speed by 4 miles per hour. It meas that his speed during the cool down portion is (x - 4) mph. Time taken to ride through the cool down portion is

18/(x - 4)

Since each portion of the workout took the same time, it means that

26/x = 18/(x - 4)

Cross multiplying, it becomes

26(x - 4) = 18x

26x - 104 = 18x

26x - 18x = 104

8x = 104

x = 104/8

x = 13 mph

His speed during the cool down portion is

13 - 4 = 9 mph

TDS and ppm are common units used to measure the quantity of substance in the water, therefore the correct answer is option A.

What is a unit of measurement?

A unit of measurement is a specified magnitude of a quantity that is established and used as a standard for measuring other quantities of the same kind. It is determined by convention or regulation.

Common units used to measure the amount of material in water are TDS and part per million.

As given in the problem we have to find out for what measurement, the units TDS (Total dissolved solid )and ppm (parts per million) are used.

The total dissolved solid and parts per million are used to measure the amount of substance present in the water, therefore the correct answer is option A.

Explanation:

We are told that the force of the person standing on the elevator is 800 N acting downwards.

We are also told that the upward force of the elevator on the person is 600 Newtons.

This means that Upward force is lesser than downward force and thus the person is accelerating downwards

A ball is dropped from a tower that is 206 m high, How long does it take to reach the ground?

Answers

It will take 6.42 s for the ball that is dropped from a height of 206 m to reach the ground.

From the question given above, the following data were obtained:

Height (H) = 206 m

Time (t) =?

NOTE: Acceleration due to gravity (g) = 10 m/s²

The time taken for the ball to get to the ground can be obtained as follow:

H = ½gt²

206 = ½ × 10 × t²

206 = 5 × t²

Divide both side by 5

[tex]t^{2} = \frac{206}{5}\\\\ t^{2} = 41.2[/tex]

Take the square root of both side

[tex]t = \sqrt{41.2}[/tex]

t = 6.42 s

Therefore, it will take 6.42 s for the ball to get to the ground.

Why is an un-magnetised iron object attracted to a magnet?

Answers

Answer:

Why is an unmagnetized iron object attracted to a magnet?

Magnets attract iron due to the influence of their magnetic field upon the iron. When exposed to the magnetic field, the atoms begin to align their electrons with the flow of the magnetic field, which makes the iron magnetized as well.

Explanation:

An un-magnetized iron object attracted to a magnet because each atom of iron object behaves like a complete magnate having north and south pole of equal strength.

The electron revolving around the nucleus of iron atom are equivalent to small current loop having magnetic dipole.

What is Magnetization?

When a magnetic material is positioned close to a magnet, it induces a density of magnetic dipole moments known as magnetization.

The motion of electrons in atoms, or the spin of the electrons or the nuclei, is what produces a material's magnetic properties; the magnetic effect can also be created by running an electrical current through the material.

When an un-magnetized iron object attracted to a magnet; every iron atoms experiences a magnetic attraction force due to magnetic field of the magnet and the atoms try to aliened themselves in such way that they can experience optimum attraction.

At the temperature [tex]10^{7}K[/tex] the hydrogen atoms fuse to form helium thus a large amount of heat is produced and stars are formed.

What causes a star to form?

Due to gravitational pull the particles and the molecules of gases become condense and by which it becomes hot. The process goes unless the temperature of the core becomes 10,000,000K.

At this temperature, the fusion takes place and energy is released.

Does a paddle boat’s wheel rotate clockwise or counterclockwise? PLS HELP

Answers

Propeller walk (also known as propeller effect, wheeling effect, paddle wheel effect, asymmetric thrust, asymmetric blade effect, transverse thrust, prop walk) is the term for a propeller's tendency to rotate about a vertical axis (also known as yaw motion). The rotation is in addition to the forward or backward acceleration.

Knowing of and understanding propeller walk is important when maneuvering in small spaces. It can be used to one's advantage while mooring off, or it can complicate a maneuver if the effect works against the pilot.
