What observations of the martian surface led lowell to the conclusion that intelligent life forms existed on mars?

Alexus [3.1K]

Icecaps that are dissolving, a system of canal-like geometric features, and various pitch black surface markings are all thought to be vegetation are the observations of the martian surface led Lowell to the conclusion that intelligent life forms existed on Mars.

<h3>What is a solar system?</h3>

It is a system that collection of all the planets and spatial bodies revolving around the sun because of the gravitational pull of the sun.

Our Solar System is based on a heliocentric model in which the Sun is assumed to reside at the central point of the planetary system.

In other words, the Sun is at the center while the Earth and other planetary bodies revolve around it.

Lowell came to the conclusion that intelligent life existed on Mars based on his observations of the martian surface, which included melting icecaps, a network of geometric patterns that resemble canals, and numerous markings on the completely black surface that are believed to be flora.

Answer:20.03 m/s

Explanation:

Given

$L_r=1:7$

velocity of Prototype $v_p=53 m/s$

Taking Froude number same for both flow as it is a dimensionless number for different flow regimes in open Flow

$(\frac{v_m}{\sqrt{L_mg}})=(\frac{v_p}{\sqrt{L_pg}})$

$v_m=v_p\times \sqrt{\frac{L_m}{L_p}}$

$v_m=53\times \frac{1}{\sqrt{7}}$

$v_m=20.03 m/s$

What cannot be used to dry utensils?

Mashcka [7]

Answer:

Wiping cloth

Explanation:

When the wiping cloth is used to “clean” another surface, it will contaminate it with the bacteria. To avoid bacterial growth on the wiping cloth, a wet wiping cloth must be stored in a proper sanitizing solution between uses. Provide Proper Concentration of. Sanitizing Solution for Wiping Cloths.

wiping cloth cannot be used on a surface where raw meat was cleaned, utensils, plates and other kitchen eating accessories because of it's ability to contact germs and bacteria.

If each wire carries a current of 67 a in the same direction, what is the magnitude of the magnetic force per meter (in nm) exer

ArbitrLikvidat [17]

The magnitude of the magnetic force per meter (in nm) exerted on each wire is 3.74 * 10^-3 N/m or 3.74v 8 10 ^6 N/nm.

Magnetic force, enchantment or repulsion that arises between electrically charged debris due to their movement. it's miles the basic pressure accountable for such outcomes as the movement of electric cars and the appeal of magnets for iron.

Magnetic pressure is a compass, a motor, the magnets that keep stuff at the fridge, educate tracks, and new curler coasters. All transferring prices supply upward push to a magnetic subject and the costs that flow thru its regions, revel in a force.

Two items containing charge with the equal path of motion have a magnetic enchantment pressure between them. in addition, gadgets with price transferring in contrary instructions have a repulsive force between them. In our article on magnetic fields we found out how transferring rate surrounds itself with a magnetic field.

explanation is given in the image below.

Force per unit length between two wires ,

F/l = μοI₁I₂/2πd

= 4π * 10^-7 *67 *67 / 2π (24 * 10^-2)

= 2 * 10 ^-7 * 67 *67/24 *10 ^ -2

= 4489/12 * 10^-5

= 3.74 * 10 ^-3 N/m
