Answer: Option (c) is the correct answer.

Explanation:

Metallurgy is defined as the branch of science in which an individual gets to known about the properties of metals along with their production and purification.

These properties of metals include both physical and chemical properties. Hence, they help in knowing the chemical and physical behavior of metallic elements.

Therefore, we can conclude that metallurgy is the study of the chemical and physical behavior of metallic elements.

The ball of a ballpoint pen is 0.5 mm in diameter and has an ASTM grain size of 12. How many grains are there in the ball
Fudgin [204]

Given :

The ball of a ballpoint pen is 0.5 mm in diameter and has an ASTM grain size of 12.

To Find :

How many grains are there in the ball?

Solution :

Volume of ball of the ballpoint is :

V = \dfrac{4 \pi r^3}{3}\\\\V = \dfrac{4\times 3.14 \times 0.5^3}{3}\ mm^3\\\\V = 0.523\  mm^3

Now, grain size of 12 has about 520000 grains/mm³.

Therefore, number of grains are :

n = 520000\times 0.523\ grains\\\\n = 271960\ grains

A horizontal rod (oriented in the east-west direction) is moved northward at constant velocity through a magnetic field that poi
sergij07 [2.7K]

Answer:

a. The east end of the rod is at higher potential than the west end.

Explanation:

The horizontal rod is oriented in the east-west direction. This means that applying right hand rule, the current will flow from the east to the west. Now, if we assume tat it is a closed loop, we know from polarity of voltage that current usually flows positive to negative terminal within a circuit.

This means the east is at a largely positive terminal while the west is at a largely negative terminal.

Thus, we can say that the east end of the rod is at higher potential than the west end of the rod.
