What are the names of the 2 charged particles in an atom and what are their charges

Physics
1 answer:
Sholpan [36]3 years ago
3 0

Answer:

Protons and electrons

Explanation:

  • The atoms are made up of protons, neutrons, and electrons.
  • The physical and chemical characteristics of an atom are determined by the number of these particle composition.
  • The protons present in the center of an atom called the nucleus is positively charged.
  • The neutrons are also located in the nucleus of an atom with no charge.
  • The electrons has a negative charge and it is placed around the nucleus having different shells and quantum state.
  • The charges of the protons and electrons are denoted by +q and -q. The quantization of these charges are +1, +2, ... and -1, -2, .... etc.

Xelga [282]

Answer:

Explanation:

mass of probe m = 474 Kg

initial speed u = 275 m /s

force acting on it F = 5.6 x 10⁻² N

displacement s = 2.42 x 10⁹ m

A )

initial kinetic energy = 1/2 m u²  , m is mass of probe.

= .5 x 474 x 275²

= 17923125 J  

B )

work done by engine

= force x displacement

= 5.6 x 10⁻² x 2.42 x 10⁹

= 13.55 x 10⁷ J  

C ) Final kinetic energy

= Initial K E + work done by force on it

= 17923125 +13.55 x 10⁷

= 1.79 x 10⁷ + 13.55 x 10⁷

= 15.34 x 10⁷ J

D ) If v be its velocity

1/2 m v² = 15.34 x 10⁷

1/2 x 474 x v² =  15.34 x 10⁷

v² = 64.72 x 10⁴

v = 8.04 x 10² m /s

= 804 m /s

Atomic nuclei are made of protons and neutrons. This fact by itself shows thatthere must be some other type of force in addition
Stells [14]

Protons and neutrons are packed together in a very small region called nucleus. Protons are positively charged and we know that like charges repel. Then how is it that protons are not repelling each other and flying away from nucleus?

You may think that gravitational force is holding all the protons together but it is not so. Gravitational force is many times weaker than repulsive force.

It is actually strong force which holds proton together. At this short distance, strong force comes into play and is several times stronger than the repulsive force.

Which is evidence that a convergent boundary once existed
Vladimir79 [104]

Volcanic islands, Mountain ranges

Explanation:

A convergent margin is plate boundary in which plates comes together. There are different types of interactions that occurs around a place where plate converges.

  • An ocean-continent convergence creates a subduction zone in which the denser oceanic plate sinks beneath the less dense continental crust.
  • As the oceanic plate begins to subside, it can melt and form chains of volcanic island within the riding continents.
  • Also, where two plates of equal densities converge, none of them subsides and this leads to upbuilding.
  • The product can be seen as extensive mountain ranges on earth like the Andes and Himalayas.

What is the current in a 160V circuit if the resistance is 2Ω? V= I= R =
sveta [45]

Answer:

80 amperes

Explanation:

Current in the circuit = ?

Voltage in the circuit = 160 Volts

Resistance = 2 Ω

Voltage = Current x Resistance

V = IR

160V = I x 2 Ω

I = 160V / 2 Ω

I = 80 Amperes

Therefore the current in the circuit is 80 amperes :)

The moon is smaller and more dense than the Earth, and has less extreme temperature changes.
Lerok [7]
<span>The moon is smaller and more dense than the Earth, and has less extreme temperature changes. The statement presented is True. In terms of temperature, since there is no atmosphere on the moon, then it has less extreme temperature changes. The moon can reach 253 Fahrenheit in the day and -387 Fahrenheit at night.</span>
