Answer:

Fusion

Explanation:

The combination of two lighter nuclie and forms a new heavier nucleus and release and lot of amount of energy is called nuclear fusion.

To start the nuclear fusion reaction we need a very high temperature.

We get energy from sun, it is due to the nuclear fusion of hydrogen and forms helium.

Answer:

Electrical force is directly proportional to the product of the charges on the two objects.

Explanation:

The electric force between two charges is given by :

$F=\dfrac{kq_1q_2}{d^2}$

Where

k is electrostatic constant

q₁ and q₂ are charges

d is the distance between charges

It can be very clear that the electric force is directly proportional to the product of charges and inversely proportional to the square of the distance between them.

Hence, the correct option is (a) "Electrical force is directly proportional to the product of the charges on the two objects".

The pH of pure water at 25°C is 7.0. The enthalpy change of the autoionization of water is +55.89 kJ/mol. What is the pH of pure

Sergeu [11.5K]

Answer:

6.14

Explanation:

If the pH falls as temperature increases, this does not mean that water becomes more acidic at higher temperatures. A solution is acidic if there is an excess of hydrogen ions over hydroxide ions (i.e., pH < pOH). In the case of pure water, there are always the same concentration of hydrogen ions and hydroxide ions and hence, the water is still neutral (pH = pOH) - even if its pH changes.

The problem is that we are all familiar with 7 being the pH of pure water, that anything else feels really strange. Remember that to calculate the neutral value of pH from Kw . If that changes, then the neutral value for pH changes as well. At 100°C, the pH of pure water is 6.14, which is "neutral" on the pH scale at this higher temperature. A solution with a pH of 7 at this temperature is slightly alkaline because its pH is a bit higher than the neutral value of 6.14.

A long, straight wire of radius R carries a steady current I that is uniformly distributed through the cross section of the wire

vitfil [10]

Answer:

When $r \ge R$

$B = \frac{ \mu_o * I}{ 2 \pi r }$

When $r< R$

$B = [\frac{\mu_o * I }{ 2 \pi R^2} ]* r$

Explanation:

From the question we are told that

The radius is R

The current is I

The distance from the center

Ampere's law is mathematically represented as

$B[2 \pi r] = \mu_o * \frac{I r^2 }{R^2 }$

$B = \frac{ \mu_o}{2 \pi } * \frac{r}{R^2}$

When $r \ge R$

=> $B = \frac{ \mu_o * I}{ 2 \pi r }$

But when $r< R$

$B = [\frac{\mu_o * I }{ 2 \pi R^2} ]* r$

A tennis ball is dropped from 1.3 m above

Dominik [7]

Answer:

2.65m/s

Explanation:

Using the equation of motion:

v² = u²+2a∆S where

v is the final velocity

u is the initial velocity

∆S is the change in distance

a is the acceleration

Given

u = 0m/s

a = 9.8m/s²

∆S = 1.3-0.943

∆S = 0.357m

Substituting the given parameters into the formula

v² = 0²+2(9.8)(0.357)

v² = 0+6.9972

v² = 6.9972

v=√6.9972

v = 2.65m/s

Hence the velocity at which it hit the ground is 2.65m/s

Give a combination of four quantum numbers that could be assigned to an electron occupying a 5p orbital.

Elden [556K]

Answer:

n=5, l=1, m(l) = -1, m(s)= + 1/2

Explanation:

Quantum number are used to describe the position and spin of an electron inside an atom. There are four types of quantum number for describing an electron inside an atom. They are: the principal quantum number, spin quantum number, magnetic quantum number and angular momentum quantum number.

(1).PRINCIPAL QUANTUM NUMBER: denoted by n, and has possible values of n= 1,2,3,4,.... IN HERE, n= 5

(2).ANGULAR MOMENTUM QUANTUM NUMBER: it is denoted by l, and has possible values of l= 0,1,2,3,...,(n-1).

Our l here is one( that is, s-orbital=0, p-orbital=1, d-orbital= 3 and so on)

(3).MAGNETIC QUANTUM NUMBER: The magnetic quantum number, which is denoted by m subscribt l, specifies the exact orbital in which you can find the electron. It has values ranging from -l,...,-1,0,1,...,l.

Here, our value is -1 that is m(l)= -1

(4).SPIN QUANTUM NUMBER: describes the orientation of electrons. Electrons can only have two values here, either a positive one and the half(+1/2) that is the spin up electron or the negative one and half(-1/2) that is the spin down electron.
