What are some examples of how we use science in or daily lives?

Answers

Answer 1

Answer:

Answer: Science is involved in cooking, eating, breathing, driving, playing, etc. The fabric we wear, the brush and paste we use, the shampoo, the talcum powder, the oil we apply, everything is the consequence of advancement of science. Life is unimaginable without all this, as it has become a necessity.

Emilio's teacher told his class that a controlled experiment's results are valid only if one factor in the experiment is changed and all the other factors remain constant. Why is this statement true?Changing several different factors in an experiment takes too much time. Changing several different factors in an experiment takes too many controls. When only one factor is changed, you don't need to use a control. When only one factor is changed, you can be more certain that it caused the results.

The model of the universe that suggests that the sun is the center of the universe was first brought by A. Brahe.
B. Kepler.
C. Ptolemy.
D. Copernicus.
Can also someone add few facts about this suggestion and its author?

Answers

It is D,Copernicus.when he first proposed the idea everyone thought he was nuts and that it was not plausible.even though his theory wasn't so accurate it still helped further scientific research.HE was born February 19,1473 and he published a book about his theory.

The correct answer is D. Copernicus.
Nicolaus Copernicus completed his education in the university of Krakow of Mathematics. He also studied the stars and planets and didn't believe that the earth was the centre of the universe. Copernicus presented his ideas in a book called ON THE REVOLUTION OF CELESTIAL SPHERES. The book wasn't published for 30 years 'cause the Roman Catholic Church opposed it!

Answers

Answer: 38.25 m

Explanation:

In this situation we need to find the distance $d$ between the rabbit and the carrot, and we can use the following equation, since the rabbit's acceleration is constant:

$V^(2)=V_(o)^(2) + 2ad$ (1)

Where:

$V=13 m/s$ is the rabbit's maximum velocity (final velocity)

$V_(o)=4 m/s$ is the rabbit's initial velocity

$a=2 m/s^(2)$ is the rabbit's acceleration

$d$ is the distance between the rabbit and the carrot

Isolating $d$ :

$d=(V^(2)-V_(o)^(2))/(2a)$ (2)

$d=((13 m/s)^(2)-(4 m/s)^(2))/(2(2 m/s^(2)))$ (3)

Finally:

$d=38.25 m$

A 60 kg person walks up a 75 m tall hill. How much gravitational potential energy do they have at the top of the hill?

Answers

Answer:

45,000 J

Explanation:

The gravitational potential energy of a body can be found by using the formula

GPE = mgh

where

m is the mass

h is the height

g is the acceleration due to gravity which is 10 m/s²

From the question we have

GPE = 60 × 10 × 75

We have the final answer as

45,000 J

A net force of -1,000 Newtons is delivered to the object over a time of .02 seconds. Calculate the new velocity of the object.

Answers

The change in velocity (v₂ - v₁) is

(-20) / (the object's mass).

Call it a crazy hunch, but I can't shake the feeling that there was more

mass, and its velocity before this force came along.

Using the information from Paul Hewitt's Conceptual Development Practice Page 25-1 and the image below, answer the following question.Image of a wave with two rulers, one vertical and one horizontal, measuring the wave is shown. The wave's first crest aligns from 0 to just less than 4 centimeters on the horizontal ruler and rises from the equilibrium located at 5 centimeters to just before 3 centimeters. The wave's first trough aligns continues to just less than 8 centimeters on the horizontal ruler and goes down from the equilibrium located at 5 centimeters to just before 7 centimeters.What was the measurement of the wavelength and amplitude respectively?

Answers

Answer:

A = 2 cm, λ = 8 cm

Explanation:

The amplitude of a wave is the maximum height it has, in this case the height is measured by the vertical ruler,

We are told the balance point is in the reading of 5 cm, that the maximum reading is 3 cm and the Minimum reading is 7 cm. Therefore, the distance from the ends of the ridge to the point of equilibrium is

d = 7-5 = 2 cm

d = 5-3 = 2 cm

A = 2 cm

The wavelength is the minimum horizontal distance for which the wave is repeated, that is measured by the horizontal ruler.

The initial reading for 4 cm and the final reading for 8 cm, this distance corresponds to a crest of the wave, the complete wave is formed by two crests whereby the wavelength is twice this value

Δx = 8-4 = 4 cm

λ = 2 Δx

λ = 8 cm

Where does the energy that the sun emits come from?

Answers

The energy emitter from the sun comes from the burning of hydrogen gasses (what the entire sun is made of) allowing light and heat energy to be created/escape.
