Answer:

Density is equal to mass divided by volume.

Explanation:

Density = mass / volume

or

p=m/v

Answer:

Use the formula D=m/v

Explanation: In order to find the volume for these objects, use a ruler and measure the length, width, and height. Proceed to multiply them all together, L*W*H. To find the mass of an object, I would say to use a triple beam balance. After finding both the mass and volume of you object, use the formula D = m/v and you'll get your answer.

Answer:

what's the question?........

The intensity of the electric current of a circuit is 123A and the electric charge is 1.7C to find the time interval in which the electric charge is transported.

Given that,

Current, I = 123 A

Electric charge, q = 1.7 C

To find,

The time interval in which the charge is transported.

Solution,

The electric current is given by electric charge per unit time. So,

[tex]I=\dfrac{q}{t}\\\\t=\dfrac{q}{I}\\\\t=\dfrac{1.7}{123}\\\\t=0.0138\ s[/tex]

So, the required time is 0.0138 seconds.

Explanation:

When it comes to environmental benefit, Reducing emission of pollutants does the best job.

Reduced emission of pollutants is a potential environmental benefit of adopting a new technology.

The elements, molecules, and particles that contribute to pollution are known as pollutants; life can be injured by exposure to these substances, and their impacts on people and plants are widely documented.

There are several ways that pollutants can enter the environment, both naturally and through human activity.

Depending on the type of pollution, what happens to it once it is released into the air, soil, or water supply.

Therefore, Reduced emission of pollutants is a potential environmental benefit of adopting a new technology.

Answer:

4048 = 115x/100.

Explanation:

Profit P = (15/100) X x.

P= 15x/100.

15x/100 = 4048- x.

4048 = 15x/100 + x.

4048 = 115x/100.

Both the transverse and longitudinal waves move faster at higher temperatures.

A wave in which the motion of the particles is perpendicular to the direction of the wave propagation is referred to as a transverse wave.

Here,

As a result of the shear stress that is produced, transverse waves are frequently observed in elastic materials.

In this situation, the oscillations are caused by the displacement of the solid particles from their relaxed state in directions perpendicular to the wave's propagation.

The wave in which the particles of the medium oscillate parallel to the direction of propagation of the wave is called a longitudinal wave.

Sound waves similarly oscillate parallel to the direction of propagation, forming the compressions and rarefactions. Hence sound waves are called longitudinal waves.

Hence,

Both the transverse and longitudinal waves move faster at higher temperatures.

Answer:

Diagram 1

Explanation:

In diagram one, the earth is leaning toward the sun, meaning it is summertime.

The person will experience summer in diagram one because the earth is tilted towards the sun.

From diagram one we can see that earth is tilted towards the sun. During summer, the North Pole of the earth is tilted towards the sun.

As a consequence, the sun’s path is higher in the sky, causing the northern hemisphere to receive more light and heat.

In addition, because the sun is in the sky for more hours, the summer solstice is also the longest day of the year.

These extra hours of sunlight give the sun more time to heat the earth and this is the main reason for summer to be the hottest season.

During summer the sun is perpendicular to the tropic of cancer and heats more areas that lie in the tropic of cancer.

Thus the answer will be diagram 1 because the earth is tilted towards the sun.

Answer:

Okay

Explanation:

First we should quickly remind ourselves of the equation for density:density= mass/ volumeTo calculate the density we need a method of measuring the mass of each object and another method for measuring the volume of each object. To measure the mass in both cases we can simply use a measuring balance. To measure the volume we will need to use 2 separate methods. For the cube we can simply measure the length, height and depth with a ruler, multiply our measurements and we obtain the volume. The statue is a little more tricky because it has an irregular shape so we can't use the ruler anymore. Instead we should use graduated tank/trough of water. First of all measure the amount of water in the tank before putting in the statue. Then submerge the statue in the water and take another measurement of the volume of water in the tank. The statue will displace the water in the tank giving a higher value. We finally subtract the initial volume from the final volume and we should obtain the volume of the statue.We now have all the measurements necessary to calculate the density of both objects!

Answer:

The mass of the sign is 44.5 kg.

Explanation:

Given that,

Force acting on the sign, F = 445 N

We need to find the mass of the sign.

Net force acting on it is given by :

F = mg

Where g is the acceleration due to gravity

[tex]m=\dfrac{F}{g}\\\\m=\dfrac{445\ N}{10\ m/s^2}\\\\m=44.5\ kg[/tex]

So, the mass of the sign is 44.5 kg.

What is the estimated volume of the table tennis ball in [tex]cm^3 [/tex] What is the estimated volume of the golf ball in

Answer: Volume of the tennis ball is [tex]38.8cm^3[/tex] and  Volume of the golf ball is [tex]33.5cm^3[/tex]

Explanation:

We have to find the Volume of tennis ball and golf ball by using the formula [tex]v=\frac{4\pi\times r^3}{3}[/tex]

Radius of the tennis ball = 2.1 cm

Radius  of the golf ball =2.0 cm.

Answer:

A. The expected electricity bill for this month is Rs 18,896.2

B. The item which consumed the most energy during the month is the electric cooker with a total consumption of 1,110Kw/Month

Explanation:

Step 1 - Identify electrical appliances

I only have 8 electrical appliances in my home.

Step 2 - Assign usage per hour and calculate wattage used /month

Step 3 - Add up all the Kw used per month and multiply by the cost of 1 Kw

Total Kilowatt Consumed/Month = 1110 +108+120+10+84.6+421.2+29.7+6.12

= 1,889.62Kw/Month

Total cost of energy consumed per month = 1889.62 * Rs 10

= Rs 18,896.2
