Answer:
The magnetic field strength is 3.9 x 10⁻³ T
Explanation:
The equation for the magnetic field strength produced by a long straight current-carrying wire is written as;
Where;
μ₀ is constant = 4π x 10⁻⁷ N/A
I is the maximum current = 20 A
r is the radius of the wire = 2.053/2 = 1.0265 mm = 1.0265 x 10⁻³ m
Substitute in this values into the equation above;
Therefore, the magnetic field strength is 3.9 x 10⁻³ T
Answer:work is done, and temperature increases
Explanation:
In an adiabatic process, when gases are compressed, work is done on the liquid and the temperature increases
It occurs when energy is supplied or withdrawn :)
Answer: Option (a) is the correct answer.
Explanation:
Global Positioning Systems (GPS) is a system which uses a network of satellites to construct maps. So, that it would be easy to trace location of a person, or to reach over a certain place.
It helps an individual by showing the route of destination wherever he/she wants to reach along with the total time to reach over the place.
Thus, GPS can determine the elevation of a given area and also it can determine latitude and longitude of a given area. As each GPS satellite broadcasts with a high power, narrow bandwidth, down link signal which can be received by our small hand held receiver antenna called mobile phone.
A GPS cannot determine the composition of soil on mountain ranges.
Thus, we can conclude that out of the given options, GPS can determine the composition of soil on mountain ranges is not true about the Global Positioning Systems (GPS).
Answer:
<h3>The answer is 8.5 kg</h3>
Explanation:
The mass of the object can be found by using the formula
where
f is the force
a is the acceleration
So we have
We have the final answer as
<h3>8.5 kg</h3>
Hope this helps you
