Answer: electron microscope

Explanation:

An electron microscope is a microscope which uses an electron beam to illuminate a specimen and it creates an enlarged image of that specimen. This microscope exhibit a very high resolving power as compared to light microscopes. This is capable of obtaining very high magnification. Some of the electron microscopes can magnify an image of the specimen upto 2 million times.

The answer is the electron microscope. It is a kind of microscope that uses electrons to light a sample and make an enlarged image. These kinds of microscopes have much better determining power than light microscopes and can get much higher magnifications.

A coil of Nichrome wire is 25.0 m long. The wire has a diameter of 0.400mm and is at 20.0°C. If it carries a current of 0.500 A,
yaroslaw [1]

The power delivered to the coil is 0.5 Watts

<h3>Resistivity of a material</h3>

The formula for calculating the power delivered to it is expressed according to the equation

Power = I²R

where

I is the current

R is the resistance

Given

Current = 0.500A

Determine the resistance using the resistivity formula

R = ρL/A

Substitute the given parameters

R = 10^-6*(25)/0.002²

R = 2ohms

Substitute

Power = I²R

Power = (0.5)²(2)

Power = 0.5watts

Hence the power delivered to the coil is 0.5 Watts

Can someone tell me how this circuit works?
ch4aika [34]

Answer:

In the scientific model, electric current is the overall movement of charged particles in one direction. The cause of this movement is an energy source like a battery, which pushes the charged particles. The charged particles can move only when there is a complete conducting pathway (called a ‘circuit’ or ‘loop’) from one terminal of the battery to the other.

A simple electric circuit can consist of a battery (or other energy source), a light bulb (or other device that uses energy), and conducting wires that connect the two terminals of the battery to the two ends of the light bulb. In the scientific model for this kind of simple circuit, the moving charged particles, which are already present in the wires and in the light bulb filament, are electrons.

Electrons are negatively charged. The battery pushes the electrons in the circuit away from its negative terminal and pulls them towards the positive terminal (see the focus idea Electrostatics – a non contact force). Any individual electron only moves a short distance. (These ideas are further elaborated in the focus idea Making sense of voltage). While the actual direction of the electron movement is from the negative to the positive terminals of the battery, for historical reasons it is usual to describe the direction of the current as being from the positive to the negative terminal (the so-called ‘conventional current’).

The energy of a battery is stored as chemical energy (see the focus idea Energy transformations). When it is connected to a complete circuit, electrons move and energy is transferred from the battery to the components of the circuit. Most energy is transferred to the light globe (or other energy user) where it is transformed to heat and light or some other form of energy (such as sound in iPods). A very small amount is transformed into heat in the connecting wires.

The voltage of a battery tells us how much energy it provides to the circuit components. It also tells us something about how hard a battery pushes the electrons in a circuit: the greater the voltage, the greater is the push (see the focus idea Using energy).

Robbie leaves his house and drives 5 miles North to the post office, 8 miles East to the park, 5 miles South to the grocery stor
Anika [276]

Answer:

Robbie's displacement is zero.

Explanation:

Displacement is called the change in position that a body experiences, from an initial point A, to an end point B, through movement. That is, displacement is understood as the length and direction that a body travels to move from an initial point to an end point. Displacement is a vector type quantity, which is described from the magnitude and the direction.

Only the start point and the end point are important for displacement. When the object ends at the same starting point, the displacement will be zero.

You know that Robbie leaves his house and drives 5 miles North to the post office, 8 miles East to the park, 5 miles South to the grocery store, and then 8 miles West to get back home.

<u><em>Since in this case the start point and end point is Robbie's house, then the offset will be zero.</em></u>
