Answer:

eccentricity is a measure of how much a conic section deviates from being circular. In particular: The eccentricity of a circle is zero. The eccentricity of an ellipse which is not a circle is greater than zero but less than 1. ... The eccentricity of a hyperbola is greater than 1.

Answer:

One can think of the eccentricity as a measure of how much a conic section deviates from being circular. In particular: The eccentricity of a circle is zero. The eccentricity of an ellipse which is not a circle is greater than zero but less than 1. ... The eccentricity of a hyperbola is greater than 1.

A ski resort consists of a few chairlifts and several interconnected downhill runs on the side of a mountain, with a lodge at th

Aleks04 [339]

A sketch of the junction between one chairlift and two runs is shown in the image attached below.
For this ski resort, it ultimately implies that the total number of lifts that are used in any closed loop would be equal to zero in accordance with Kirchhoff's loop rule.

<h3>What is Kirchhoff's loop rule?</h3>

Kirchhoff's loop rule is also referred to as Kirchhoff's second law or Kirchhoff's voltage law, and it states that the algebraic sum of all the electric potential differences around any closed loop is equal to zero.

<h3>How to connect two runs in series?</h3>

Since the chairlifts are analogous to batteries, and the runs are analogous to resistors, the two runs would represent resistors that are connected in series with the lift, which represents the battery. Similarly, these three runs can also be connected in parallel by altering the positions of the runs with the battery.

For this ski resort, it ultimately implies that the total number of lifts that are used in any closed loop would be equal to zero in accordance with Kirchhoff's loop rule.

Which properties are characteristics of non metals

Natasha2012 [34]

Non - Metals:

Non- metals are bad conductor of electricity ( except Graphite ).

Non- metals are also bad conductor of heats. ( except diamond )

Non - metal are neither malleable nor ductile. They are brittle.

Non-metal are not strong.

Non-metal are not sonorous.

Some terms:

★ Malleable: This means that metals can be beaten into thin sheets with hammer.

★ Ductile: This means that metals can be drawn into thin wires.

★ Brittle: This means that non-metal break into pieces on hammering.

★ Sonorous: This means capable of producing a ringing sound.

Answer:

Brownian motion and diffusion

Explanation:

Brownian motion: taking into consideration, SMOKE. when a burning fire is kindled, smoke is seen to move in the way or direction that is not straight but keep changing continuously ( in haphazard manner). Haphazard manner of smoke is an evidence that matter are made of molecules and are constantly in motion

A grasshopper jumps straight up at 5.33 m/s. How much time does it take for it to return to earth? If u know please help.

sattari [20]

1) Time to get the highest point of it pathway>

Vf = Vo - g*t

Vf = 0 (condition of maximum height)
Vo = 5.33 m/s
g = 9.81 m/s

=> t = Vo / g = 5.33 m/s / 9.81 m/s = 0.543 s

2) Time to return from the highest point = time to get to the highest point = 0.543 s

Total time = 0.543s + 0.543 s = 1.086 s ≈ 1.09 s

Answer: 1.09 s
