Answer:
Time = 4.1 s
Explanation:
Momentum = mv = (12000)(4.25) = 51000 kg m/s
Momentum = Impulse (mv = ft) so
51000 = (9200)t
t = (51000)/(9200) = 5.54 seconds
Impulse of the current and the engine must equal so (ft = ft)
51000 = (12500)t
t = (51000)/(12500) = 4.08
But accounting for significant figures, time equals 4.1 seconds
The color of the peak is yellow-green.
Answer:
Winds are caused by differences in air pressure. Unequal heating of Earth’s surface creates areas of different pressure. Cooler areas have higher air pressure. Warmer areas have lower pressure. This causes air to move from high pressure to low pressure. This movement is the wind we feel.
plz mark me as brainliest.
Answer:
Less powerful
Explanation:
Hurricanes rely on warm water. It sucks heat energy from the water to use for fuel. Warmer water means more moisture, which also mean a bigger and/or stronger hurricane. The North Atlantic is definitely much colder than the Caribbean so the hurricane will not have much fuel.
Have a great day!
If silicic rock is found in a core sample, its location is likely underneath an ocean or a mountain.
Answer: Option A
<u>Explanation:</u>
Silicic rock are the type of rocks which are made up of silica and are located at the crust of the earth which is more likely to the core lying underneath and it extends all the way up to 30 km.
Its density is around 2 gm / cm^3 .One of the common example of silica is granite. So if the silicic rocks are found in a core it is more likely underneath the ocean or mountain.
