Answer:
Headlands and bays are created where there are bands of hard and soft rock which meet the coastline at right angles. Softer rock is eroded more quickly and erodes backwards to form bays (which may have beaches). The harder rocks are more resistant to erosion and jut out into the sea to form exposed headlands
Answer:
Sulphur(iv) oxide gas
Explanation:
S + O2 — SO2
According to the equation, the element sulphur S reacts with oxygen gas O2 to form
Sulphur (iv) oxide .
Answer:
24.26 m/s
Explanation:
= Linear density of string =
T = Tension on the string = mg =
g = Acceleration due to gravity = 9.81 m/s²
Velocity of a string is given by
The velocity of the wave is 24.26 m/s
Answer:
Explanation:
Let assume the first connect have resistor R1 and R2
Then, this are connected in parallel
But, parallel connection of resistor have the same voltage.
So the power dissipated in each resistor is given as
P1=V²/R1
P2= V²/R2
If another resistor is added in parallel nothing change by the way each resistor dissipate power
Then, power dissipated in R3 is
P=V²/R3
Why we use parallel circuit at home
Parallel circuits are used in homes because the loads can be operated independently of each other.
Each load gets the full voltage of the circuit.
