What is the biggest similarity between sports in the United States and sports in other cultures?
PLEASE ANSWER QUICKLY!
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.

A diverging lens will always produce an image with _______.
a) a negative focal length and a magnification more than 1
b) a positive focal length and a magnification more than 1
c) negative focal length and magnification less than 1
d) a positive focal length and a magnification less than 1
Answer:
Option C
Explanation:
Diverging lens are negative lens as they have negative focal length. Their
magnification is smaller than one.
They produce virtual image in which the refracted rays extended back in order to meet
Hence, option C is correct
Tâm ống dẫn đặt dưới đường phân giới giữa nước và thuỷ ngân h1 = 820mm, chênh lệch chiều cao cột thuỷ ngân h2 = 880mm (Hg = 13,6). Ap suất dư tại điểm A trong ống dẫn (at)?
Answer:
P = 79993.43245
Explanation:
Được -
Vị trí tâm ống dẫn dưới đường thuỷ ngân h1 = 820 mm
Chênh lệch chiều cao của cột thủy ngân h2 = 880mm
Tỷ trọng của thủy ngân = 13,5951 g / cm3
P = mật độ * gia tốc do trọng lực a * h
Thay thế các giá trị đã cho, chúng ta nhận được -
P = 13,5951 g / cm3 * 980,665 cm / s2 * (88-82) cm
P = 79993.43245

Answer:
7. F
8. T
Explanation:
7. An anion is indicated by a negative superscript charge (- something) to the right of the atom. For example, if a sodium atom loses one electron, it will have one more proton than electron, giving it an overall +1 charge. The chemical symbol for the sodium ion is Na+1 or just Na+
8.Like charges repel each other; unlike charges attract. Thus, two negative charges repel one another, while a positive charge attracts a negative charge. The attraction or repulsion acts along the line between the two charges
1.) False
2.) True

calculate:An elcetric lamp is rated 240V and 40W. What is the cost of running the lamp for 62 hours if the elctricity authorities charges #2.50k per KWH
Explanation:
The voltage of the lamp, V = 240 V
Power of the lamp, P = 40 W
It is running for 62 hours.
The cost of running is $2.50k per KWH
Electric power is,
P = 40×62 Wh
= 2480 Wh
P = 2.48 kWh
At the rate of $2.5 per kWh
P = $6.2
So, the cost of running is $6.2 per kWh.

Explain how you would apply any five pricing techniques to attract customers
Answer:
Explanation:
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.

Why does Quito, Equator has very little changes to the daylight hours
throughout the year?
Because of the position on the equator, the change in rotation of the Earth on its axis throughout the year doesn't affect it much. Unlike the poles, Quito is almost constantly in direct view of the sun. So, because of lack of change in rotation, the daylight hours are hardly varied as Quito is almost constantly in more or less the same spot in relation to the sun.

In which of the following do two smaller atoms fuse to form a larger atom?
Fission.
Fusion.
Neither
Both
Answer:
Fusion
Explanation:
A chemical reaction can be defined as a reaction in which two or more atoms of a chemical element react to form a chemical compound.
On the other hand, a nuclear reaction can be defined as a reaction in which the nucleus of an atom is transformed by being joined (fusion) or split (fission) with the nucleus of another atom of a radioactive element.
This ultimately implies that, during fusion, two smaller atoms fuse to form a larger atom. Thus, fusion involves the joining of two smaller nuclei of atoms to form a single massive or heavier nucleus with the release of energy.
Additionally, the energy that holds the neutrons and protons found in the nucleus of an atom together is known as Nuclear energy.
