Answer:

Convection currents are the result of differential heating. Lighter (less dense), warm material rises while heavier (more dense) cool material sinks. It is this movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth.

J-s. If your 1400-kg car is parked in an 8.54-m-long garage, what is the uncertainty in its velocity? cm/s the tolerance is +/-2

IgorC [24]

Answer:

$\Delta v = 4.41 \times 10^{-37} cm/s$

Explanation:

As per Heisenberg's uncertainty principle we know that

$\Delta P \times \Delta x = \frac{h}{4\pi}$

so here we have

$\Delta P = m\Delta v$

$\Delta x = 8.54 m$

now from above equation we have

$m\Delta v \times (8.54) = \frac{h}{4\pi}$

$1400(\Delta v) \times (8.54) = \frac{6.626 \times 10^{-34}}{4\pi}$

$\Delta v = 4.41 \times 10^{-39} m/s$

$\Delta v = 4.41 \times 10^{-37} cm/s$

Assume that each cubic centimeter of water has a mass of exactly 1.00 g. what is the mass of one cubic meter of water in kilogra

statuscvo [17]

The mass of one cubic meter of water in kilograms is 1 kg.

This is a conversions case. First, we must determine how many cubic centimeters there are in a cubic meter. We have 1000 of these after conversion.

This essentially indicates that 1000 units of water, each with a volume of one cubic centimeter, would have to combine before we could create a cubic meter of water.

Knowing that one cubic centimeter weighs one gram, 1000 cubic centimeters would weigh 1000 * 1, or 1000g, or one kilogram.

Thus, 1 cubic meters of water will weigh 1 * 1000g = 1000g, or just 1 kg.
