Answer:
Current, I = 1.08 A
Explanation:
Given that,
Length of the copper wire, l = 12 cm = 0.12 m
Mass of the wire, m = 16 g = 0.016 kg
Magnetic field, B = 1.2 T
The magnetic field is oriented perpendicular to the wire. We need to find the current in the wire.
Magnetic force, F = BIL
Force of gravity, F' = mg
F' = F
I = 1.08 A
So, the current through the wire is 1.08 A. Hence, this is the required solution.
Some humans judge temperature without the use of instruments include:
- touching the object
- feeling the radiant energy
<h3>What is temperature?</h3>
Temperature is the measure of the degree of hotness or coldness of a substance.
Temperature of substances are usually measured using thermometers.
The choice of thermometer depends on the temperature range to be measured.
However, some crude ways of measuring temperature include:
- touching the object
- feeling the radiant energy
In conclusion, temperature measures the hotness or coldness of objects.

Answer:
Star A is closer than Star B
Explanation:
As we know that in parallax method of distance measurement the angle subtended by the star when it covers a distance of one Parsec arc length, it is known as parallax angle
Here we can say
so we have
so here we have
angle subtended by Star A = 1 arc sec
angle subtended by star B = 0.75 arc sec
now we have
distance for star A is given as
distance of star B is given as
So star A is closer than star B
Use force (thrust) equals mass times acceleration.
14 g is the solubility per 100 g water, since it is difficult to read the graph.
<span>Then, in 130 g H20 the solubility would be 14 g KNO3/100 g H2O x 130 g H2O = 18 g KNO3 </span>
<span>The question asks how much crystallizes. </span>
<span>Initial 34.0 g minus 18.0 g still dissolved = 16.0 g crystallizes.</span>
