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
Mass, mass is anything that’s takes up space and has weight
Water doesn't belong on that list.
If it's removed, then there's a space to add GAS, which does belong.
Answer:
current = 10A
Explanation:
recall the formula, Power = current * voltage
120 W = current * 12V
current (A) = 120 W / 12V
current = 10A
Answer:
Energy used by television in 20 seconds = 3000 J
Explanation:
We have expression for power, P = Work / Time
Here we have power of television = 150 Watts
Time of working of television = 20 seconds.
We need to find energy it uses in 20 seconds, that is we need to find work done by electricity in 20 seconds.
Work done = Power x Time = 150 x 20 = 3000 J
Energy used by television in 20 seconds = 3000 J
