The answer is 20 meters would be the water depth started to feel bottom. This is half of the wavelength. The reason behind this is the wave travels half or the partial of the wavelength underneath the surface. For that reason that is where the wave would be starting to feel the ground.
Answer:
I = 3.42 A
Explanation:
Ohm's law gives a relationship between the potential difference and the current passing through a conductor. The formula of Ohm's Law is given as follows:
V = IR
where,
V = Voltage
I = Current
R = Resistance
Initially:
V = 14 volts
I = 4 A
R = ?
Therefore,
14 volts = (4 A)R
R = (14 volts)/(4 A)
R = 3.5 Ω
Now, when V becomes 12 volts and R remains constant:
V = IR
12 volts = I(3.5 Ω)
I = (12 volts)/(3.5 Ω)
<u>I = 3.42 A</u>
D. An ice skater spinning in place
rest is the state of a body which is stationary relative to a particular frame of reference or another object. When the state of a body does not changes with time with respect to its surroundings in a particular frame of reference that time it is said to be at rest.
in other words we can say that when a body has zero velocity and its position is not changing with time relative to its surrounding then it is said to be at rest.
For example a chair on which you are sitting is at rest or a table on which your desktop is kept is rest because its position is not changing.
Answer:
Option (3)
Explanation:
The environmental lapse rate usually refers to the rate at which there occur changes in the atmospheric temperature with respect to the changing elevation. The atmosphere is somewhat static, it is neither rising nor sinking, on average, so this lapse rate in the environment would comparatively different than the dry or moist adiabatic lapse rates.
At night, the air present in the lower elevation or near the surfaces cools at a faster rate in comparison to the air that is at a higher altitude, so the lapse rate typically decreases at night.
Hence, the correct answer is option (3).
