pls help i’ll give brainliest if you give a correct answer!!

Infrared wave basically have shorter wavelengths than X-rays. The correct option is A.

A section of the electromagnetic radiation spectrum with wavelengths ranging from roughly 700 nanometers (nm) to one millimetre is known as infrared radiation (IR), or simply infrared (mm).

While shorter than radio waves, infrared waves are longer than visible light waves.

Infrared radiation has the ability to ease muscle tension and encourage local blood circulation.

Infrared radiation has been used in conventional medicine to treat conditions including autoimmune diseases and issues with wound healing in addition to relieving muscle pain and tension.

Infrared waves are shorter than radio waves but longer than visible light waves.

Thus, the correct option is A.

Answer:

increase

Explanation:

The formula for the gravitation for of attraction is:

[tex]F = \dfrac{Gm_1m_2}{r^2}[/tex]

It implies that the force of attraction is inversely proportional to the square of the distance. i.e.

[tex]F \infty \dfrac{1}{r^2}[/tex]

where;

G = gravitational constant

m = mass; &

r = distance between the two objects.

Now let's assume that the distance between is reduced from 1 to half;

Then:

[tex]F \infty \dfrac{1}{\Big (\dfrac{r}{2} \Big)^2}[/tex]

[tex]F \infty \dfrac{4}{r^2}[/tex]

Thus, the new gravitational force of attraction increased by a factor of 4.

Explanation:

Newton's second Law of motion F = ma

F = (0.6)(55) = 33N

Answer:

Highest.

Explanation:

This is because, in a state of unstable equilibrium, the center of gravity is at highest which as a result of when the body topples at it's base, there is a shift in the centre of gravity, and the centre of gravity shift position by moving towards the lower position and it does not return to it's former position again.

Answer:

The comet is locked in the Sun's gravity. as it falls deeper in the gravity we'll, its velocity increases. As is travels closer to the Sun, it is trying to break away, but cannot. This transforms into a sideways movement that produces a tight turn. It races further out of the gravity well, and sheds velocity.

Answer:

a. The moment of the 4 N force is 16 N·m clockwise

b. The moment of the 6 N force is 12 N·m anticlockwise

Explanation:

In the figure, we have;

The distance from the point 'O', to the 6 N force = 2 m

The position of the 6 N force relative to the point 'O' = To the left of 'O'

The distance from the point 'O', to the 4 N force = 4 m

The position of the 4 N force relative to the point 'O' = To the right of 'O'

a. The moment of a force about a point, M = The force, F × The perpendicular distance of the force from the point

a. The moment of the 4 N force = 4 N × 4 m = 16 N·m clockwise

b. The moment of the 6 N force = 6 N × 2 m = 12 N·m anticlockwise.

Answer: drying paint

Explanation:

From the options that are given in the question, we should note that car manufacturers use radiation for drying paint.

The radiation is vital as it keeps the car cool and also helps in the reduction if heat in the vehicle. The other options such as sealing windows, cleaning tires and lubricating engines aren't true as radiation isn't used for that purpose by the car manufacturers.

Answer:

The layers of rock at Earth ’s surface contain evidence of the evolutionary processes undergone by these components of the terrestrial environment during the times at which each layer was formed. By studying this rock record from the very beginning, it is thus possible to trace their development and the resultant changes through time.

Answer:

v = 3.57 m / s

Explanation:

Let's use Newton's second law in the upper part of the circle, with the minimum speed so that the water does not rest on the circle, that is, the normal is zero

          W = m a

acceleration is centripetal

          a = v² / r

let's substitute

         mg = m v² / r

         v = [tex]\sqrt{r g }[/tex]

let's calculate

        v = [tex]\sqrt{1.3 \ 9.8}[/tex]ra 1.3 9.8

        v = 3.57 m / s

The number of paper clips in step 2 is the same as the number of paper clips in step 3 is a true statement, as the mass is the same for both.

It is possible to define every mechanical quantity in terms of mass, length, and time. The SI unit for mass, denoted by the letter m, is the kilogram. While mass is typically thought of as an immutable feature of an item, relativistic mass must be taken into account when traveling at speeds close to the speed of light.

Given:

The mas of the paper clips are the same,

Assume the number of clips in step two is x and the mass is m, the mass in the third step is the same as in step 2,

Thus, the number of clips = Total mass of paper clip / mass of one clip,

The number of clips = m / x

As we can see, if the mass is equal, then the number of clips will also be equal.

Answer: objects A and B have the same speed.

Explanation:

Speed = distance divided by time.

Object A: 65 miles in 13 minutes

Speed (A) = 65 miles divided by 13 minutes

Speed (A) = 5 miles per minute

Object B: 125 miles in 25 minutes

Speed (B) = 125 miles divided by 25 minutes

Speed (B) = 5 miles per minute

Thus, objects A and B have the same speed.
