Answer:
3.125 × 10¹³ Electrons
Explanation:
Data provided in the question:
Charge per unit length on rod = 0.00500 C/m
Length of the rod = 1 mm = 1 × 10⁻³ m
Therefore, the total charge on the rod
= Charge per unit length on rod × Length of the rod
= 0.00500 C/m × ( 1 × 10⁻³ m)
= 5 × 10⁻⁶ C
Thus,
Number of electrons removed
= total charge on the rod ÷ Charge of an electron
= 5 × 10⁻⁶ ÷ (1.6 × 10⁻¹⁹)
= 3.125 × 10¹³ Electrons
C. Electrons, nucleus
Chemical reactions involve the atom's electrons, while nuclear reactions involve the atom's nucleus.
Answer:
Alloys and Composites
Explanation:
<u>Drill bits are made of alloys</u> because alloys are very much resistant to corrosion and are created when one or multiple metals are mixed with other elements that are non-metallic in nature. Due to their greater strength, they are used in the power drills in order to create borehole drills at the mining site. Borehole drilling is commonly done in order to understand the sub-surface strata before mining.
<u>The bodies along with the handles of power drills are constructed of composite insulators</u> because within the composites there is the absence of free electrons that has the ability to flow and produce electricity. So they are considered to be used as a good insulator.
The ball will float as it’s density is less than the salt water.
