Write in powers of 10 notation: 3 trillion; five-thousandths; 730,000,000,000,000; 0.000000000082.

Answers

The numbers in power of 10 notation would be :

3 trillion is expressed as 3 ×  10¹².

Five-thousandths (0.005) are expressed as 5 × 10⁻³.

730,000,000,000,000 is expressed as 7.3 × 10¹⁴.

0.000000000082 is expressed as 8.2 × 10⁻¹¹.

3 trillion:

In standard form: 3,000,000,000,000

In powers of 10 notation: 3 × 10¹²

Explanation: In this number, 3 is multiplied by 10 raised to the power of 12, indicating that it is 3 followed by 12 zeros. This notation is particularly useful when dealing with very large numbers like the national debt or astronomical distances.

Five-thousandths (0.005):

In standard form: 0.005

In powers of 10 notation: 5 × 10⁻³

Explanation: Here, 5 is multiplied by 10 raised to the power of -3, indicating that it is 5 divided by 1,000 (10³). This notation helps represent fractions or very small quantities.

730,000,000,000,000:

In standard form: 730,000,000,000,000

In powers of 10 notation: 7.3 × 10¹⁴

Explanation: In this case, 7.3 is multiplied by 10 raised to the power of 14, indicating that it is 7.3 followed by 14 zeros. This notation simplifies the expression of extremely large numerical values.

0.000000000082:

In standard form: 0.000000000082

In powers of 10 notation: 8.2 × 10⁻¹¹

Explanation: Here, 8.2 is multiplied by 10 raised to the power of -11, indicating that it is 8.2 divided by 100 billion (10¹¹). This notation is useful when working with very small decimal fractions, such as in scientific measurements.

Powers of 10 notation with superscripts provides a clear and concise way to represent numbers across a wide range of scales, from the macroscopic to the microscopic, making it a fundamental concept in scientific notation.

If an object is being pulled by two forces, one 4 N to the left and the other 2 N to the right, what is the net force acting on the object?

Answers

Since this object is being pulled by two forces, the net  force acting on the object is 2 Newton, to the left.

  • Let the first force be A.
  • Let the second force be B.

Given the following data:

  • Force A = 4 Newton, to the left.
  • Force A = 2 Newton, to the right.

To find the net  force acting on the object:

A net force can be defined as the vector sum of all the forces that are acting on a physical object or body.

This ultimately implies that, a net force is a single (one) force that substitutes the effect of all the forces acting on a physical object or body.

Mathematically, net force is given by the following:

Net \;force = F_1 + F_2 + F_3 + F_4 + .....F_n

Where:

  • F represents each force.

In this scenario, the forces are acting in opposite directions (left and right) and as such, we would subtract the two forces:

Net\;force = F_A - F_B\n\nNet\;force = 4 - 2

Net force = 2 Newton, to the left.

Note: The direction is to the left because Force A has more magnitude than Force B, so the object would be pulled to the left.

We know velocity of sound v=a₩(omega), but speed does not depend on amplitude, why?

Answers

The amplitude of a wave does not affect the speed at which the wave travels. The speed of a wave is only altered by alterations in the properties of the medium through which it travels.
Here’s some fun facts:
The amplitude of a sound wave determines its loudness or volume. A larger amplitude means a louder sound, and a smaller amplitude means a softer sound.

Which two objects have the greatest gravitational force acting between them

Answers

Answer:

the mass of two objects and the distance between two objects

Explanation:

Final answer:

The gravitational force between two objects depends on their masses and the distance between them. The two objects in the universe with the greatest gravitational force acting between them are the Earth and Sun due to the Sun's mass and the relatively short distance between Earth and the Sun.

Explanation:

The gravitational force between two objects depends on two major factors according to the universal law of gravitation: the masses of the two objects and the distance between them. In essence, the greater the mass of the objects, the greater the gravitational force between them; and the closer the objects are to each other, the stronger this force will be.

Considering these factors, the two objects in the universe that have the greatest gravitational force acting between them are the Earth and the Sun. The Sun is the most massive object in our solar system and the Earth, though not the largest, is relatively close to the Sun compared to most other objects in space.

What portion of the electromagnetic spectrum can human eyes detect? A.
visible light

B.
visible light and infrared light

C.
infrared light

D.
infrared light and ultraviolet light

Answers


Well, there's a very definite reason why a certain sliver of the electromagnetic
spectrum is called "visible". 

The meaning of the word 'visible' is 'can be seen with eyes', and that's the label
given to the part of the electromagnetic spectrum that can be seen with eyes.
It doesn't include infrared or ultraviolet radiation, because those cannot be seen
with eyes.  Only the 'visible' wavelengths can.



Answer:

visible light
