Answer As a wave travels across the open ocean, it gains speed. When a wave reaches a shallow coastline, the wave begins to slow down due to the friction caused by the approaching shallow bottom. ... Think of it like driving a car at high speed and then slamming on the breaks. Everything is going to fly to the front.:Waves at the Shoreline: As a wave approaches the shore it slows down from drag on the bottom when water depth is less than half the wavelength (L/2). The waves get closer together and taller. ... Eventually the bottom of the wave slows drastically and the wave topples over as a breaker. hope this helps have a nice night❤️❤️❤️

Answer:
False
Explanation:
Density is more of a physical property
(b) At 24 W and 12 V, the bulbs can operate with the largest current of 2 A.
Answer:
Option B.
Explanation:
Power consumed in light bulbs are measured in terms of voltage and current. As it is known that power dissipated in an electric circuit is directly proportional to the square of current and also to resistance.
Power = I²R
As by Ohm's law, V = IR, then Power = VI
Here, V is the voltage and I is the current flowing through the bulb.
So here the power and voltage is given and we have to determine the largest current. So from the formula it can stated that current flowing through the bulb will be directly proportional to the power dissipated by the circuit and inversely proportional to the voltage at which the circuit is operated.
So for the given options, the current value is as follows:
(a) I = P/V = 3.2/6=0.5333 A
(b) I = P/V = 24/12 = 2 A
(c) I= P/V = 16/18 =0.9 A
(d) I = P/V = 32/24 = 1.3 A
Thus, the option B is having the maximum voltage at which the bulb can be operated. So at 24 W and 12 V, the bulbs can operate with the largest current of 2 A.
