Answer:
d = 79 m
, d = -43 m
Explanation:
This in an exercise of movement in one dimension, the displacement is a vector and the distance is the scalar
Let's calculate the distance
d = 35 + 18 +26
d = 79 m
Displacement which is a vector
d = -35 +18 - 26
d = -43 m
thebold indicate vector. The negative sign indicates that the movement is to the left
A simple electromagnet consisting of a coil of insulated wire wrapped around an iron core<span>. A </span>core<span> of ferromagnetic material like </span>iron<span> serves to increase the magnetic field created. The strength of magnetic field </span>generated<span> is proportional to the amount of </span>current<span> through the winding.</span>
Answer:
A
Explanation:
Work = force * distance
= 100 n * 0 = 0 work done
Answer:
Temperature is simply a measure of energy present. The heating and cooling of the atmosphere cause currents as cold air moves towards warmer air.
Explanation:
The most basic thing to understand is that warm air wants to rise while cold air wants to sink. Hot air contains fewer molecules per cubic meter while cold air contains more, hence the warm air will rise up over colder air. The most common example of this is the existence of a hot or cold front. These fronts are simply boundaries between hot and cold air.
