The idea is to divide the mass by the volume. If, for example, the mass is in kilograms and the volume is in liters, then the density will have the units kilogram/liter.

If the time lag between seeing the flash of lighting and hearing the thunder is 4 seconds how far away is the lighting?

The time lag between seeing the flash of lightning and hearing the thunder corresponds to the distance between you and the lightning strike. To calculate this distance, you can use the fact that sound travels at approximately 343 meters per second in air. So, for a 4-second time lag, the lightning strike is approximately 1372 meters away.


Why then doesn't earth fall toward us when we jump?

It does, but because the Earth is so much more massive than a person, the movement is extremely small, far too small to be measured. Action and reaction are equal and opposite, and momentum is conserved when you jump - the sum of your momentum and the Earth's. Supposing you have a mass of 70 kg and you apply a jumping force of 140 kg or 1372 Newtons for 0.1 seconds, an impulse of 137.2 Newton-seconds. Impulse equals change of momentum so your momentum is Mv = Ft or in this case 70 x v = 137.2 and your upward speed is initially 1.96 metres per second. For the Earth the same applies and Mv = Ft tells us the the Earth's downward speed initially is given by 6E21 x v = 137.2 so that the Earth's inital speed is 2.3E-20 metres per second - assuming that the Earth is totally rigid! That is a displacement that is far too small to be detected. NB the notation 6E21 is an alternative that means six times ten to the power 21 on web sites that fail to provide the normal subscripted notation.

What is the ratio of surface area if the surface area is 588 and the volume is 1372?

To find the ratio of surface area to volume, we divide the surface area by the volume. Given a surface area of 588 and a volume of 1372, the ratio is ( \frac{588}{1372} ), which simplifies to approximately 0.429. Thus, the ratio of surface area to volume is about 0.429:1.


What is the ratio of surface area to volume for a sphere with following measurements surface area 588 And volume 1372?

To find the ratio of surface area to volume for the sphere, you divide the surface area by the volume. Given that the surface area is 588 and the volume is 1372, the ratio is ( \frac{588}{1372} \approx 0.428 ). Thus, the ratio of surface area to volume for the sphere is approximately 0.428.


What is the ratio of surface area to volume for a sphere with the following measurements Surface area 588 m2 Volume 1372 m3?

To find the ratio of surface area to volume for the sphere, we divide the surface area by the volume. Given the surface area is 588 m² and the volume is 1372 m³, the ratio is calculated as follows: ( \frac{588 \text{ m}^2}{1372 \text{ m}^3} \approx 0.429 \text{ m}^{-1} ). Therefore, the ratio of surface area to volume for the sphere is approximately 0.429 m⁻¹.

What dimensions do you need for a cylinder to have the same volume as a sphere with a radius of 7?

Volume sphere = 4/3 πr³ = 4/3 π 7³ = 1372π/3 Volume cylinder = πr²h = 1372π/3 → r²h = 1372/3 So as long as the radius of the cylinder is related to its height by: radius = √(1372 / (3×height)) or height = 1372 / (3×radius²) You can have a cylinder of almost any size you want. Example sizes: radius 1, height 1372/3 radius 7, height 28/3 height 7, radius 14/√3 height 28/3, radius 7 height 49, radius √(28/3)

What is the ratio of surface area to volume for a sphere with the following measurements surface area equals 588 M squared volume equals 1372 m to the Third?

The formula for the surface area of a sphere is 4πr² and the formula for the volume is (4/3)πr³, where r is the radius of the sphere. Setting 4πr² equal to 588 and (4/3)πr³ equal to 1372, you can solve for the radius by equating the two expressions and taking the cube root of the result. Once you have the radius, you can calculate the surface area using the formula and divide it by the volume to find the ratio.
