Answer:

False

Explanation:

<em>Accuracy vs precision.</em>

In the field of science in general, precision is the ability of an instrument to obtain the same result in different measurements, developed under the same conditions. On the other hand for statistics, engineering, or science in general, accuracy is the ability of an instrument to measure a value close to the actual magnitude.

Take a look at the picture I attached you. From left to right:

1. Low accuracy, Low precision

2. High precision, Low accuracy

3. High accuracy, low precision

4. High accuracy, High precision

An electric kettle is rated at 2 kW when connected to a 230 V electrical supply

Oliga [24]

Explanation:

a) P = IV

2000 W = I (230 V)

I = 8.7 A

b) The fuse must be rated for a higher current than the kettle, so use the 13A fuse.

c) Double insulation means there are two layers of insulation, insuring that the wires cannot touch the outer casing of the kettle and protecting the user from electrical shock.

d) V = IR

230 V = (8.7 A) R

R = 26.5 Ω

Two common stars are observed by an astronomer. It turns out that the first one is twice as hot as the second. This indicates that the first emits around 16 times as much energy as the second.

<h3>Describe about astronomers?</h3>

The two main categories of astronomers are observational and theoretical. Direct observations of celestial objects are made by observational astronomers, who then evaluate the results. Theoretical astronomers, on the other hand, develop and research models of phenomena that cannot be seen. Because a system of stars or a galaxy has a life cycle that lasts millions to billions of years, astronomers must take photographs of various systems at distinct stages in order to understand how they create, develop, and die. They build models or run simulations using these data to theorize about how various astronomical objects function.

Classify each possible hypothesis about a medicinal aloe vera plant as falsifiable or non-falsifiable.

pychu [463]

Answer:

Aloe vera is a succulent plant species ( with fleshy water storing tissue) belonging to the genus Aloe.

It is used in many products ( including beverages, cosmetic products as gel, medicinal ointments). Its juice is quite bitter in taste. It is known to be the best skin moisturizer and can be used for healing wounds by enhancing the renewal of damaged cells. It is also used as an anticarcinogen, thus reduces the chances of cancer.

Thus, the given hypothesis can be classified as falsifiable ( which is proven wrong) or non-falsifiable ( which is proven right) in the following way-

Falsifiable-

Aloe vera juice tastes better than carrot juice.

Non Falsifiable-

Aloe vera gel is the best natural skin moisturizer.

Aloe vera gel can heal wounds by boosting cell renewal.

Drinking aloe juice can reduce the risk of lung cancer.
