True or false energy is always lost in a circuit

Physics

1 answer:

Llana [10]3 years ago

7 0

Explanation:

Electrons will gain energy as they are "pushed" from different points in the circuit. This energy is then lost when the electrons flow through circuit components such as a light bulb.

What is the mass of a man who accelerates 4 m/s2 under the action of a 200 N net force?

Over [174]

Answer:

$\huge \boxed{ \boxed{50 \: kg }}$

Explanation:

The mass of the man can be found by using the formula

$m = \frac{f}{a} \\$

f is the force

a is the acceleration

From the question we have

$m = \frac{200}{4} \\$

We have the final answer as

Hope this helps you

Define Inertia with an example

DochEvi [55]

Answer:

Inertia resists change in motion. Objects want to stay in rest or motion unless an outside force causes a change. For example, if you roll a ball, it will continue rolling unless friction or something else stops it by force.

EXAMPLE: when you shake a branch the leaves get detached.

Which property of matter is an extensive, rather than an intensive, property of matter?.

leonid [27]

A property known as an extensive property depends on the quantity of materials in a sample. A couple of instances of extensive attributes are mass and volume. A property of matter that is intensive depends solely on the type of matter in a sample and not on the quantity.

<h3>Which of the following is intensive as opposed to extensive?</h3>

An intense property is a structural characteristic of a system that is independent of the system's size or the volume of its constituent parts. Volume and internal energy are extensive qualities while density, pressure, and temperature are intensive ones.

<h3>What is an illustration of a extensive property?</h3>

The features that depend on the amount of matter present are referred to as extensive properties. Volume, mass, internal energy, etc. are some examples.

<h3>What are some instances of a substance's extensive and intensive properties?</h3>

Temperature, T, refractive index, n, density, and object hardness are a few examples of intensive attributes. In contrast, subsystems' comprehensive attributes, such as mass, volume, and entropy, are additive. However, not all physical characteristics of matter fit within those categories.

Please hurry Describe why electric currents can be dangerous

konstantin123 [22]

Answer:

Cardiac Arrest, burns, and nerve damage.

Explanation:

Basically, the main risk is cardiac arrest, caused by the electric current interfering with the normal operation of the heart muscle. Other possible damages are burns due to the electric energy vaporizing the water inside the cells, and nerve damage caused by excessive current through the nerves.

The centripetal force : F = 293.3125 N

<h3>Further explanation</h3>

Given

mass = 65 kg

v = 9.5 m/s

r = 20 m

Required

the centripetal force

Solution

Centripetal force is a force acting on objects that move in a circle in the direction toward the center of the circle

$\large {\boxed {\bold {F = \frac {mv ^ 2} {R}}}$

F = centripetal force, N

m = mass, Kg

v = linear velocity, m / s

r = radius, m

Input the value :

F = 65 x 9.5² / 20

F = 293.3125 N
