Answer:

equipment for the measurement of microwave L bands with a range between 1 GHz and 2 GHz.

Explanation:

The electromagnetic spectrum can be calculated with the relationship between the speed of light, its wavelength and its frequency.

c = λ f

For reasons of analysis and equipment used, it is artificially divided into ranges, with poorly defined limits and in some cases with overlaps between some.

For the case of analysis, f = 1.41 10⁹ Hz, we have the range called

* Microwave for f> 3 108 Hz to approximately f <3 1011 Hz

For the lower part of the frequency 3 10⁸ <f <3 10⁹ Hz we have UHF television channels and cell phones and military communications.

As the frequency observed by the researchers is in the UHF range, it is possible that they are using microwave equipment for communications, specifically equipment for the measurement of microwave L bands with a range between 1 GHz and 2 GHz.

If a net horizontal force of 0.8 N is applied to a toy whose mass is 1.2 kg what acceleration is produced?

julia-pushkina [17]

Answer:

Explanation:

The acceleration of an object given it's mass and the force acting on it can be found by using the formula

$a = \frac{f}{m} \\$

f is the force

m is the mass

From the question we have

$a = \frac{0.8}{1.2} \\ = 0.666666...$

We have the final answer as

Hope this helps you

What is the mass of an object that is 6kg on a planet with an acceleration due to gravity

goldfiish [28.3K]

Answer:

Mass of the body will be = 6 kg

Explanation:

Given:

Mass of an object = 6 kg

Acceleration due to gravity of the planet = 10 $m/s^2$

To find the mass of the body on that planet.

Solution:

Mass of the body is defined as the total amount of matter contained in the body.

Thus, mass of a body will always remain constant irrespective of the acceleration due to gravity. This is because it is an independent quantity and does not vary with acceleration due to gravity.

<em>It is the weight of the body that changes with the change in the acceleration due to gravity as it is given by:</em>

$W=mg$

where $m$ represents mass of the body and $g$ represents the accelration due to gravity.

Hence, the mass of the given body will remain = 6 kg.
