Which type(s) of subatomic particles can be located within the nucleus of an atom?

1 answer:

6 0

According to the research, the correct option is c. Protons and neutrons are subatomic particles can be located within the nucleus of an atom.

It is the minimum unit of a substance, which makes up all common matter and is made up of a nucleus with protons and neutrons and several orbital electrons, the number of which varies according to the chemical element.

In this sense, protons are subatomic particles that have a positive energetic charge, while neutrons have no charge.

Therefore, we can conclude that according to the research, the correct option is c. Protons and neutrons are subatomic particles can be located within the nucleus of an atom.

Consider the following four objects: a hoop, a flat disk, a solid sphere, and a hollow sphere. Each of the objects has mass M an

Mumz [18]

Answer:

The hoop

Explanation:

We need to define the moment of inertia of the different objects, that is,

DISK:

$I_{disk} = \frac{1}{2} mR^2$

HOOP:

$I_{hoop} = mR^2$

SOLID SPHERE:

$I_{ss} = \frac{2}{5}mR^2$

HOLLOW SPHERE

$I_{hs} = \frac{2}{3}mR^2$

If we have the same acceleration for a Torque applied, then

$mR^2>\frac{2}{3}mR^2>\frac{1}{2} mR^2>\frac{2}{5}mR^2$

$I_{hoop}>I_{hs} >I_{disk}>I_{ss}$

The greatest momement of inertia is for the hoop, therefore will require the largest torque to give the same acceleration

Learning Task 3: Read the characteristics of mixtures given in the second column. Identify if it is homogeneous or heterogeneous

madreJ [45]

1. Components can be separated by physical means [heterogenous]

2. The additive component is so finely dispersed in the main ingredient such that it can't be seen [homogenous]

3. Particles are uniformly distributed [homogenous]

4. The substances are identified in different phases [heterogenous]

5. Particles are non-uniformly distributed [heterogenous]

A homogenous mixture is a type of mixture in which the composition is uniform throughout the mixture.

Characteristics of a homogenous mixture:

the mixture is uniform
the composition is the same
it consists of one phase

A heterogenous mixture is a type of mixture in which the composition of the mixture is not uniform

Characteristics of heterogenous mixture include;

it contains two or more ingredients or phases.

different phases mixed together, which are physically separated

samples obtained from different parts of the mixture may have a different composition

In the given characteristics of the mixture in the question we can classify them as follows;

1. Components can be separated by physical means --heterogenous

2. The additive component is so finely dispersed in the main ingredient such that it can't be seen --- homogenous

3. Particles are uniformly distributed ---- homogenous

4. The substances are identified in different phases ---- heterogenous

5. Particles are non-uniformly distributed ---- heterogenous

When you take your 1900 kg car out for a spin, you go around a corner of radius 53 m with a speed of 13 m/s. If the co-efficient

V125BC [204]

Answer:

Yes, you would be safe without skidding off

Explanation:

In this situation the sum of forces on the car would be:

$F_f = m*\frac{V^2}{R}$

$F_f = 1900*\frac{13^2}{53}$

$F_f = 6058.5N$

And the maximum friction force is:

$F_fmax = \mu*N$

$F_fmax = \mu*m*g$

$F_fmax = 0.75*1900*10$

$F_fmax = 14250N$

Since the required force is smaller than the maximum force, we can say it will not skid off

g as measured from the earth, a spacecraft is moving at speed .80c toward a second spacecraft moving at speed .60c back toward t

cupoosta [38]

Answer:

the speed of the first spacecraft as viewed from the second spacecraft is 0.95c

Explanation:

Given that;

speed of the first spacecraft from earth v $_a$ = 0.80c

speed of the second spacecraft from earth v $_b$ = -0.60 c

Using the formula for relative motion in relativistic mechanics

u' = ( v $_a$ - v $_b$ ) / ( 1 - (v $_b$ v $_a$ / c²) )

we substitute

u' = ( 0.80c - ( -0.60c) ) / ( 1 - ( ( 0.80c × -0.60c) / c² ) )

u' = ( 0.80c + 0.60c ) / ( 1 - ( -0.48c² / c² ) )

u' = 1.4c / ( 1 - ( -0.48 ) )

u' = 1.4c / ( 1 + 0.48 )

u' = 1.4c / 1.48

u' = 0.9459c ≈ 0.95c { two decimal places }

Therefore, the speed of the first spacecraft as viewed from the second spacecraft is 0.95c

Help me plzzzz

KiRa [710]

Answer:

C. Mg3N2

Explanation:

Magnesium has a positive 2 charge and nitrogen has a negative 3 charge. To completely balance it out, you need three magnesium’s and two nitrogen’s. The final charge for magnesium would be positive 6 and the final charge for nitrogen would be negative 6, this will make it neutral.
