calculate the answer to the correct number of significant digits
0.055 * 5.1 =

Answer:

Time

Explanation:

To find velocity (also known as distance), you need both the speed and time.

Answer:

Infinite

Explanation:

Young's modulus is infinite and bulk modulus is zero.

Answer:

Young's modulus is the ratio of tensile stress ( force of elasticity ) to tensile strain ( extension ).

Explanation:

[tex]E = \frac{stress}{strain} [/tex]

Answer:

The refractive index of the outer coating is 1.52.

Explanation:

Refractive index of interior part, n' = 1.97

critical angle, C = 50.4°

Let the refractive index of the coating is n.

Use the Snell's law,  

[tex]n\times sin r = n'\times sinC\\\\n\times sin 90 = 1.97 \times sin 50.4\\\\n = 1.52[/tex]

Answer:60

Explanation:

Explanation:

First find the area of the entire floor:

Area of a rectangle= length × width

( 4000mm× 3600mm)

14400000mm²

Area of one square tile??= side ×side

12cm×12cm

144cm²

Convert cm to mm

1cm²=100mm²

144cm²=144cm²/1cm²×100mm²

=14,400mm²

Number of tiles required to cover the entire floor= 14400000mm²/14400mm²

=1000

Answer:

40 degrees Celsius

Explanation:

Have a great summer :)

Answer:

speed

(distance per time)

Kathy is faster btw

Answer:

20 = 30 / t1

t1 = 3/2

40 = 30 / t2

t2 = 3/4

average speed = total distance / total time taken

= 30 + 30 / 3/2 + 3/4

= 60 /9/4

= 60 × 4/9

= 26.667

Answer:

1. Efficiency

2. Kinetic energy

3. Pulley

4. Screw

5. Wedge

Explanation:

1. Efficiency: the ratio of work output to work input or the ratio of actual mechanical advantage (AMA) to ideal mechanical advantage (IMA).

Mathematically, the efficiency of a machine is given by the formula;

[tex] Efficiency = \frac {MA}{IMA} * 100 [/tex]

2. Kinetic energy: the energy of a moving object. Kinetic energy (KE) is an energy possessed by an object or body due to its motion.

Mathematically, kinetic energy is given by the formula;

[tex] K.E = \frac{1}{2}MV^{2}[/tex]

Where;

K.E represents kinetic energy measured in Joules.

M represents mass measured in kilograms.

V represents velocity measured in metres per seconds square.

3. Pulley: a grooved wheel over which a rope can move. It is made up of a wheel and rope which allows force to be multiplied such as in a drawing well.

4. Screw: a double-sided inclined plane. It is held in position and then used to tighten two or more objects together.

5. Wedge: an inclined plane wrapped around a cylinder. It can be used to split objects into halves.

1. DECOY PRICING

This occurs when customers make a purchase they must often choose between products with different prices and attributes.

This method of pricing is meant to influence the consumer's purchasing decision and maximise the sales of one particular product. The seller will offer at least three products; two of the products will have a similar or equal price. The two products with the similar prices should be the most expensive ones, and one of the two should be less attractive than the other.

2. LOSS LEADER

This is when a product is sold at a low price (often without profit) in order to stimulate other profitable sales or to attract new customers.

The main is that it will help the business to expand their market share as a whole. It's common practice when first entering a market as it introduces new customers to a service or product in the hope of building a customer base and securing future

3.ODD PRICING

This is a method of psychological pricing a product. Prices ending in 9, 95, 97, 99 are sometimes called “charm prices” and in this type of pricing, the seller fixes a price where the last digits are odd numbers. This is intended to give the buyer no room for manœuvering or for bargaining as the price appears to be less - a product priced at £9.99 will seems much cheaper than one priced at £10.00

4. PRICE DISCRIMINATION

The purpose of price discrimination is to capture the market's consumer surplus and generate the most revenue possible for a product. Identical goods or services are sold at different prices from the same provider to different segments of the market. Industries that commonly use price discrimination include the travel industry, pharmaceuticals and textbook publishers.

5. PRODUCT BUNDLE PRICING

Using this method, sellers will combine several products in the same package. It also serves to move old stock. Blu-ray and videogames are often sold using the bundle approach once they reach the end of their product life cycle. This technique is used at auctions where one attractive item may be included in a lot with a box of less interesting things. Buyers must bid for the entire lot. It’s a good way of moving slow selling products, and in a way is another form of promotional pricing.

Answer:

Excessive heat causes atoms to move more rapidly, disturbing the magnetic domains. As the atoms are sped up, the percentage of magnetic domains spinning in the same direction decreases. This lack of cohesion weakens the magnetic force and eventually demagnetizes it entirely.

Answer:

if there is only one planet in the universe and the ball is there it will have 0 kinetic energy if the ball is in the very center of that planet only if the planet itself is absolutely motionless. its at its highest if the planet is moving away from the ball at a slightly faster speed forever. Between point A and B both potential energy and kinetic energy are at perfect 0.

Explanation:

never will have a measurable kinetic or potential energy status unless every single object is included in the calculation.

PEEL writing offers writers the ability to write through a structure. It helps to express your ideas and opinions to the reader in writing a PEEL paragraph.

Explanation:

PEEL writing gives your thoughts a deep perception. The writing techniques are very simple, but they can be complicated.

The Point, Evidence, Explanation and Link is an acronym for PEEL. All of them belong to the paragraph. The main way to master PEEL writing is consistent practise. You will find it very easy to learn when you understand the nature of the essay. Other important aspects of writing are planning and research.

Point:-

This is the most important, because it is the first part of the paragraph. The first sentence describes the point to be discussed in the entire paragraph. The opening phrase is the subject phrase. To make them understand the whole paragraph, the first sentence should be clear to the audience.

This section is also a key part of the essay. After you have written an analysis, you have a clear idea of what the reader can convey.

Answer:

The first difference is fairly straightforward: other countries prefer other sports. While some aspects of American sports culture are universal there are other things that are sports-specific, such as the 7th-inning stretch at a baseball game or counting the steps of a basketball player after he fouls out.

Find answers below.

Explanation:

1. Radiant: the energy of light.

2. Light: makes it possible to see things.

3. Sun: a source of light. This source of light is referred to as solar energy and it's renewable source of energy.

4. Crest: top of wave. Thus, it's typically the highest part of an electromagnetic wave.

5. Trough: bottom of wave. Thus, it's typically the lowest part of an electromagnetic wave.

6. Wavelength: distance from one point on one wave to the same point on the next wave.

7. Infrared light: it has longer wavelengths than visible light.

8. X-rays: shorter wavelengths than visible light.

Electromagnetic waves is a propagating medium used in all communications device to transmit data (messages) from the device of the sender to the device of the receiver.

An electromagnetic spectrum refers to a range of frequency and wavelength that an electromagnetic wave is distributed or extends. The electromagnetic spectrum comprises of gamma rays, visible light, ultraviolet radiation, x-rays, radio waves, and infrared radiation.

Answer:

Linear motion, also called rectilinear motion, is one-dimensional motion along a straight line, and can therefore be described mathematically using only one spatial dimension.

Explanation:

Rotation around a fixed axis is a special case of rotational motion. The fixed-axis hypothesis excludes the possibility of an axis changing its orientation and cannot describe such phenomena as wobbling or precession
