Which type of exercise is weightlifting?

MatroZZZ [7]

The answer is option B "anaerobic." Weightlifting deals with stress to the muscles when lifting weights and due time the muscles will begin to adapt and get stronger. Other examples of anaerobic exercise are things like: weight training, sprinting, cycling, and jumping anything that has short exertion, and high-intensity movement is an anaerobic exercise.

Hope this helps!

if Xc = 7,500 and the resistance is 10,000 in a series RC circuit , what is the impedance of the circuit?

mr_godi [17]

Answer:

The impedance of the circuit = 12500 Ω

Explanation:

<em>Impedance:</em> This is the overall opposition to the flow of current in an a.c circuit by any two or all of the three circuit elements.(R, L, C) is called <em>impedance.</em>

<em>The S.I unit of Impedance is Ohms. (Ω), It can be represented mathematically as</em>

Z = √(Xc² + R²).................... Equation 1

Where Z = impedance, Xc = reactance of the capacitor, R = resistance of the resistor.

<em>Given: Xc = 7500 Ω, R = 10000 Ω</em>

<em>Substituting these values into equation 1,</em>

<em>Z = √(7500² + 10000²)</em>

<em>Z = √(56250000 + 100000000)</em>

<em>Z = √(156250000)</em>

Z =12500 Ω

Therefore, The impedance of the circuit = 12500 Ω

A 100-year flood is the flooding elevation that has a one percent chance of happening each year. Why is the name misleading

fenix001 [56]

One percent annual chance of flooding does not mean it will happen with absolute certainty once every 100 years. Just that the expected value of a flood in 100 years is one.

As an example, heads has a 50% chance of happening every coin flip. With 2 coin flips, the expected value is one. However, it would be a misnomer to call "heads" a 2-flip outcome.

Question #5: Explain how a reflecting telescope is different from a refracting telescope. List the two different types of reflec

Anni [7]

The main component in a reflecting telescope is a mirror where the light will bounce off and is then focused into a smaller area. In contrast, a refracting telescope uses lenses that focus the light as it travels towards the other end.

Two different types of reflecting telescopes are:

1.Cassegrain reflector

2.Newtonian telescope

Explanation:

The distinction between the two is in how they manipulate the incoming light in order to magnify the image. The main component in a reflecting telescope is a mirror where the light will bounce off and is then focused into a smaller area.
Key advantage of reflecting telescopes is how big you can make them. With lenses, the maximum size is limited to about one meter, largely because of the problems stated above as well as the skyrocketing costs.
The Newtonian telescope, also called the Newtonian reflector, is a type of reflecting telescope invented Sir Isaac Newton, using a concave primary mirror and a flat diagonal secondary mirror. The Newtonian telescope's simple design has made it very popular with amateur telescope makers.
The Cassegrain reflector is a combination of a primary concave mirror and a secondary convex mirror, often used in optical telescopes and radio antennas, the main characteristic being that the optical path folds back onto itself, relative to the optical system's primary mirror entrance aperture.
