I'm pretty sure that this answer is correct please let me know!

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: 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 ans i 1 ohm

Explanation:

if i cut a resistor of 9 ohm into 3 equal parts then each resistor will have a resistance of 3 ohm and if they are in parallel combination the net resistance will be R

so 1/R=1/R1+1/R2+1/R3

     1/R=1/3+1/3+1/3

Answer:

Weight = 9800Newton

Explanation:

Given the following data;

Mass of car = 1000kg

Acceleration due to gravity = 9.8m/s²

To find the weight of the car;

Weight is given by the formula;

Weight = mass * acceleration due to gravity

Substituting into the equation, we have;

Weight = 1000*9.8

Weight = 9800Newton

Average Speed Calculation - suppose we want to calculate Usain Bolt's average speed during his world record winning 100 m sprint race in Berlin on August 16, 2009. What do we know?

We want to calculate Bolt's average speed

The distance was, of course, 100 meters

Bolt ran the distance in 9.58 seconds.

Bolt ran 11.42 yards per second during the race. Setting meters per second, you get 10.44 mp/s; miles per hour - 23.35 mph; kilometers per hour - 37.58 km/h; etc.

Travel Time Calculation - Suppose, you drove 21 miles with an average speed of 45 miles per hour. How long did you drive?

You traveled 28 minutes.

Distance Calculation - Let's calculate, how many miles you can travel, driving 2 hours and 30 minutes with an average speed of 55 miles per hour?

As you can see, the answer is 137.5 miles or 221.28 kilometers or 119.48 nautical miles, etc.

Assume, V - stands for average speed (velocity), T - stands for traveling time, and D - stands for traveled distance.

Average speed can be calculated by using the formula: V = D/T

The traveled distance can be calculated as D = V*T

Traveling time can be calculated using: T = D/V

Using the formulas remember about the units. For example, if the distance is given in meters and the time is given in seconds, the calculated average speed is given in meters per second. To convert it to other units of measurement, you can use our speed converter. If the distance is given in yards and speed is given in miles per hour, to get time in hours, you HAVE TO convert yards to miles or miles per hour to yards per hour first.

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.

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.
