Answer:

The measured value of the constant is known with some certainty to four significant digits. In SI units, its value is approximately 6.674×10−11 m3⋅kg−1⋅s−2. The modern notation of Newton's law involving G was introduced in the 1890s by C. V. Boys.

Sergeu [11.5K]

The answer is B. X-rays and gamma rays. The electromagnetic spectrum consists of all types of electromagnetic radiation. The EM spectrum is arranged from the longest wavelength with the lowest frequency and lowest energy which are the radio waves and microwaves to the shortest wavelength with the highest frequency and highest energy which are the x-rays and gamma rays. Visible light that can be seen by a humans is a small portion in between the ultraviolet and infrared rays.

A person walks 45 m East and then walks 39 m at an angle 40◦ North of East. What is the magnitude of the total displacement? Ans

vredina [299]

Answer:

r = 78.95 m

Explanation:

given,

Person Walk in east, r₁ = 45 m

Then he walk, r₂= 39 m in the direction of 40◦ North of East.

writing the total displacement in x- direction

r₁ₓ = 45 m

r₂ₓ = 39 cos 40°

r₂ₓ = 29.87 m

total displacement in x-direction

rₓ = r₁ₓ + r₂ₓ

rₓ = 45 + 29.87

rₓ = 74.87 m

displacement in y-direction

r_{1y} = 0 m

r_{2y} = 39 sin 40°

r_{2y} = 25.07 m

total displacement in y- direction

r_y = 25.07 m

using Pythagoras theorem for the magnitude calculation

$r = \sqrt{r_x^2 + r_y^2}$

$r = \sqrt{74.87^2 +25.07^2}$

r = 78.95 m

The magnitude of total displacement is equal to 78.95 m.

Answer:

Catastrophic theories

Explanation:

The theory of catastrophe is a collection of methods used to analyze and describe the ways in which a system can experience sudden significant behavioral changes when one or more of the variables that govern it are continuously modified.

Georges Louis de Buffon suggested in 1745 the first destructive theory — that a comet pulled material from the Sun to form the planets.

Therefore the answer is -

You select a rental package that includes a car with an average consumption of 6.00 liters of fuel per 100 km. Considering that

7.21 USD.

<h3>Further explanation</h3>

<u>Problem:</u>

Given in Europe, the average fuel cost is 1.063 euros/liter.
A car with an average consumption of 6.00 liters of fuel per 100 km.

<u>Question: </u>

How much (in US dollars) will we spend properly on fuel on our trip? Express the answer numerically in US dollars to three significant figures.

Let us convert the unit price from the euro to USD. Currently, the exchange rate of 1 euro is 1.13 USD.

$\boxed{ \ 1.063 \ euro \times \frac{1.13 \ USD}{1 \ euro} = 1.20119 \ USD \ }$

The term euro is crossed out.

After currency conversion, the average fuel cost is 1.20119 USD/liter.

We need 6.00 liters of fuel during the trip.

$\boxed{ \ 6.00 \ liters \times \frac{1.20119 \ USD}{1 \ liter} = 7.20714 \ USD \ }$

The term liter is crossed out.

We rounded up to three significant figures. Hence, the cost that we will spend on fuel on our trip is as much $\boxed{\boxed{ \ 7.21 \ USD \ }}$

<em>Want to follow another way? Let's see.</em>

$\boxed{ \ 6.00 \ liters \times \frac{1.063 \ euros}{1 \ liter} = 6.378 \ euro \ }$

The term liter is crossed out.

$\boxed{ \ 6.378 \ euro \times \frac{1.13 \ USD}{1 \ euro} = 7.20714 \ USD \ }$

The term euro is crossed out.

We get a similar result, i.e.,

$\boxed{\boxed{ \ 7.21 \ USD \ }}$
