There are many types of forces. Which statement best compares an electrical force to gravitational force?
Murrr4er [49]

Answer: it is A.

Explanation:

Compare the electric force and gravitational force. ... Both forces are inversely proportional to the square of the distance between the objects, this is known as the inverse-square law. ... If there are two charges that are DIFFERENT, they attract.

Can someone answer all 3 questions plz?
nordsb [41]

Question one should be obvious..

Mass can't be created not destroyed no matter what, so even in a chemical reaction, the answer will remain. The first answer is correct.

Question two

No, because even when water is broken down, there should only be one molecule of oxygen. The fact there is two means it's incorrect.

Question three

Yes. The equation is perfectly balanced on both sides, so it's safe to say the value of mass remains constant.

Advances in medical technology and healthcare have increased the life expectancy of people around the world. what negative effec
Ghella [55]

The negative effect of technology on Healthcare:

Impersonal treatment, harmful health impacts, higher expenditures, the potential for overuse, and privacy violations are just a few of the negative effects of medical technology.                

Medical technology:

It refers to all technological tools or apparatus utilized to protect human life. Medical equipment such as an insulin pump, a wireless brain sensor, a blood glucose meter, a digital thermometer, pulse oximeters, smart inhalers, etc the tools which had helped patients receive better medical treatment.

Effects of Medical technology:

Medical technology, nevertheless, can potentially cause issues for the patient like:

1. <u><em>Impersonal treatment</em></u>: When a healthcare professional uses technology too frequently, they could spend less time getting to know the patient as a person and more time dealing with the equipment.

2. <u><em>Harmful health impacts</em></u>: Surgery, radiation therapy, and chemotherapy are a few examples of treatments that might be advantageous but also have risks.

3. <u><em>Higher expenditures</em></u>: Due to the research and marketing required to bring new technologies to market and to generate a profit for their creators and manufacturers, they may result in increased patient costs.

4. <u><em>Potential for overuse:</em></u> The use of a technology or new product by a medical professional may be encouraged by the manufacturer, regardless of whether it is in the patient's best interest.

5. <u><em>Privacy violation</em></u>: Electronic medical records (EMR), for example, collect and manage patient information. This new technology is convenient, but it also has the potential to be misused, compromising patient privacy and personal data.

A cup of coffee (140g) cools from 75°C down to comfortable room temperature 20°C. How much energy does it release to the surroun
Thepotemich [5.8K]

Given that the mass of coffee in the cup = 140 g

Final temperature = 20^{0}C

Initial temperature = 75^{0}C

Let us assume the specific heat of coffee is equal to that of water = 4.184\frac{J}{g^{0}C }

Temperature change = T(final) - T(initial) = (20 - 75 )^{0}C

                                                                   =- 55 ^{0}C

-Heat given out by coffee = heat absorbed by the surroundings

Heat released into the surroundings =-(mC(T_{final}-T_{initial}))

                                             = -(140g)4.184\frac{J}{g^{0}C }( -55^{0}C)

                                             = 32,217 J
