How many atoms are in a cell

Physics
1 answer:
FrozenT [24]4 years ago
7 0
There are approximately 100 trillion atoms in a human cell. Approximately the same number of cells are in the entire human body, meaning that 10 octillion atoms or a 1 followed by 28 zeros make up each person.

What is the difference between displacement and distance travelled​
IrinaK [193]
Displacement in Space
It is the length of a body's real route. It is the shortest distance between the body's final and beginning positions.
It's a number with a scalar value. It's a quantity with a vector.
It can't possibly be negative. It might be a negative number, a zero number, or a positive number.

What is the elastic potential energy of a spring that is compressed a distance of 0.35 m and has a spring constant of 71.8 N/m?
Vitek1552 [10]

Answer:

P.E = 4.398 Joules.

Explanation:

Given the following data;

Spring constant, k = 71.8N/m

Displacement, x = 0.35m

To find the elastic potential energy;

The elastic potential energy of an object is given by the formula;

P.E = \frac {1}{2}kx^{2}

Substituting into the equation, we have;

P.E = \frac {1}{2}*71.8 *(0.35)^{2}

P.E = 35.9 * 0.1225

Elastic potential energy = 4.398 Joules.

<em>Therefore, the elastic potential energy of the spring is 4.398 Joules. </em>

describe how you would connect a voltmeter to measure the potential difference across a resistor and an ammeter to measure the c
Vesna [10]

A voltmeter needs to be connected in parallel to the two sites in order to measure the potential difference between them.

<h3>What is a voltmeter?</h3>
  • The electrical potential difference between two locations in an electric circuit is measured using a voltmeter.
  • The potential difference between two ends of a current-carrying conductor is measured using a voltmeter.
  • On a scale that is typically measured in volts, millivolts (0.001 volts), or kilovolts, a voltmeter primarily monitors the voltage of direct or alternating electric current (1,000 volts).
  • Numerous voltmeters are digital and display readings as numbers.
<h3>How is a voltmeter connected?</h3>
  • A galvanometer with high resistance is a voltmeter.
  • Any portion of an electrical circuit can be measured.
  • Due to its high resistance, it is linked in parallel so that it does not impact the circuit's overall net resistance and does not draw any current by itself.
  • A device's voltage is measured by a voltmeter connected in parallel, and its current is measured by an ammeter connected in series.

An electric motor is connected to a battery. The current flows through brushes to a commutator ring, which is attached to a elec
Rzqust [24]

Answer:

Commutator is a ring which reverse the direction of current in AC circuit so that the coil connected to it will continuous to move in the same direction.

Explanation:

In motors there exist a coil which is rotated due to torque of magnetic field when current flow through it. Since AC current is used to run the motor so we know that AC current changes its direction after half cycle.

So here commutator plays an important role to reverse the direction of current after every half cycle so that the current goes in same direction always into the coil.

This will produce a constant direction torque on the coil so that it will rotate in same sense always.

So commutator role is to provide same direction current to the coil by reversing its direction after every half cycle
