Answer:
Suck up the iron using the electromagnet.
Explanation:
Iron is magnetic and copper is not. So copper will be
unaffected by the magnet. After extracting the iron,
open the switch. The electromagnet will lose its
magnetism and the iron fillings will fall off..
Answer:
the correct answer is B
Explanation:
The kinetic model of the movement describes that the movement of the molecules increases with the increase of their internal energy, which in a macroscopic sample is reflected in an increase in the temperature of the sample.
The sample graph shows the function of temperature over time, which is why our kinetic model establishes that there is an increase in the movement of water molecules.
Consequently the correct answer is B
Answer:
The families are thought to form as a result of collisions between asteroids. In many or most cases the parent body was shattered, but there are also several families which resulted from a large cratering event which did not disrupt the parent body (e.g. the Vesta, Pallas, Hygiea, and Massalia families).
We have: K.E. = mv² / 2
Here, m = 1 Kg
v = 4 m/s
Substitute their values in the formula,
K.E. = 1×4² / 2
K.E. = 16/ 2
K.E. = 8 J
Finally, answer of your question would be 8 Joules.
Hope this helps!
The biological process that directly converts energy from the Sun into chemical energy would be Photosynthesis. It is a process carried out by autotrophic organisms which are predominantly plants and other photosynthetic bacteria.
