It would not be the richter scale, so the answer would be false, it would be the Mercalli scale

The Answer Is False. A seismometer detects the vibrations caused by an earthquake. It plots these vibrations on a seismograph. The strength, or magnitude, of an earthquake is measured using the Richter scale. The Richter scale is numbered 0-10.

Answer: Flammability is a chemical property only.

Odor, density, melting point, boiling point, and solubility are all physical properties.

Formation of a gas, temperature change, and color change can all indicate a chemical change or a physical change has occurred, depending on if the substance's composition is changed in the process.

sergij07 [2.7K]

Answer:

9.60 m/s

Explanation:

The escape speed of an object from the surface of a planet/asteroid is given by:

$v=\sqrt{\frac{2GM}{R}}$

where

G is the gravitational constant

M is the mass of the planet/asteroid

R is the radius of the planet/asteroid

In this problem we have

$\rho = 2.02\cdot 10^6 g/m^3$ is the density of the asteroid

$V=3.09\cdot 10^{12}m^3$ is the volume

So the mass of the asteroid is

$M=\rho V=(2.02\cdot 10^6 g/m^3)(3.09\cdot 10^{12} m^3)=6.24\cdot 10^{18} g=6.24\cdot 10^{15} kg$

The asteroid is approximately spherical, so its volume can be written as

$V=\frac{4}{3}\pi R^3$

where R is the radius. Solving for R,

$R=\sqrt[3]{\frac{3V}{4\pi}}=\sqrt[3]{\frac{3(3.09\cdot 10^{12} m^3)}{4\pi}}=9036 m$

Substituting M and R inside the formula of the escape speed, we find:

$v=\sqrt{\frac{2(6.67\cdot 10^{-11})(6.24\cdot 10^{15})}{(9036)}}=9.60 m/s$

What are the magnifications of the objective lenses

Anvisha [2.4K]

Answer:

Objective Lenses: Usually you find 3 or 4 objective lenses on a microscope. They almost always consist of 4x, 10x, 40x and 100x powers, when coupled with a 10x (most common) eyepiece lens, total magnification is 40x (4x times 10x) 100x, 400x and 1000x

Explanation:

Objective lenses come in various magnification powers, with the most common being 4x, 10x, 40x, and 100x, also known as scanning, low power, high power and typically oil immersion objectives, respectively
