Answer:

The law of conservation of mass or principle of mass conservation states that for any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as the system's mass cannot change, so quantity can neither be added nor be removed

The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.

Vertical distance h isΔg $=\frac{-2GM}{ RE^{3} }$

<h3>What is vertical?</h3>

The distance between two vertical places is known as the vertical separation or vertical distance. There are numerous ways to express vertical position using vertical coordinates, including depth, height, altitude, elevation, etc.
The formula for vertical distance from the ground is y = - g * t2 / 2, where g is the acceleration of gravity and h is a height.
The vertical distance between the measurement point and the point of observation on Earth's surface. Altitude is the vertical distance from the measurement place to mean sea level.

Assuming h is small in comparison to the radius of the Earth, show that the difference in free-fall acceleration between two points separated by vertical distance h isΔg = (2GMeH) / RE³:

Given:

Separated between two points=h

And, h∠∠ $R_{E}$ ( $R_{E}$ = radius of the Earth)

Now, $\frac{dg}{dr} =$ $\frac{-2GM}{ RE^{3} }$

$dg =\frac{-2GM}{ RE^{3} } dr$

Δg $=\frac{-2GM}{ RE^{3} }$

Therefore, Vertical distance h isΔg $=\frac{-2GM}{ RE^{3} }$

A 3600-N Force causes a car to accelerate at a rate of 4m/s2. What is the mass of the car?

Mademuasel [1]

Answer:

14400 kg

Explanation:

According to Newton's second law of motion, F = ma

F = 3600 N

a = 4m/s2

3600 = m/4

3600*4 = m

m = 14400 kg

Therefore the mass of the car is 14400 kg

The speed of a shallow water wave varies with

Sergio039 [100]

So we want to know how does the speed of a shallow water wave varies. If the wavelength is large enough in comparison to the depth of the water, meaning the wavelength is 20 times longer than the depth of water, the speed of a shallow water wave is the square root of gravity times water depth or: v=√(g*d), where v is speed of the wave, g=9.81 m/s^2 and d is water depth.
