Answer:
Option (D)
Explanation:
Wind erosion will take place extensively as the cliff-side is exposed on the outcrop. Due to the wind erosion, the large, jagged rock will undergo the process of weathering where the softer parts of the rock will be eroded much rapidly in comparison to the harder parts, as a result of which the overall size of the rock will decrease and the surface will be uneven and somewhat rough. This will take place over a due course of time. The main agent that is responsible for erosion is the wind.
Thus, the given rock will become smaller and less smooth after a definite period of time.
Thus, the correct answer is option (D).
Answer:
The potential difference across the source is 30.45 V.
Explanation:
In this setup we have a voltage divider, we were given the voltage difference on one of the resistors, we know that the difference pottential from the source in this case is the sum of the voltage in each individual resistor, so we can use the following equation to solve this problem:
V_resistor5.4 = (V_source)*(R_5.4)/(R_5.4+R_8.3)
V_source = (V_resistor5.4)*(R_5.4+R_8.3)/(R_5.4)
V_source = (12)*(5.4+8.3)/5.4
V_source = (12)*(13.7)/5.4 = 30.45 V
he potential difference across the source is 30.45 V.
Answer:

Explanation:
Length of the conveyor belt is given as

time taken to cook one burger is given as

now we can find the speed of the belt as



Now we know that the distance between two burgers is given as 25 cm

now the production rate of burgers is given as





Answer: In physics a drift velocity is the average velocity attained by charged particles, such as electrons, in a material due to an electric field.
