The densities of the cannonball and the unknown liquid are 3.54kg/m³ and  2.686 kg/m³.

When an object is fully or partially submerged in liquid, the vertical upward thrust is acting on the object, this force is called the buoyant force.

Salt Water exerts a buoyant force to the cannon ball  = 124−89 = 35N, which equals the weight of water displaced.

The mass of water displaced is  

W/g =35/10 =3.5 kg.

Since the density of salt water is 1kg/L, the volume displaced is 3.5L.

Therefore the density of the cannon ball is  

=(124/10) /3.5 =3.54kg/L = 3.54kg/m³

The unknown liquid exerts a buoyant force of 124−30=94 N.

The density of this liquid is  (94/10) /( 3.5​ )=2.686 kg/liter = 2.686 kg/m³

Thus,  the densities of the cannonball and the unknown liquid are  3.54kg/m³ and  2.686 kg/m³.

The relation between the electric intensity and electric flux is that the electric flux is equal to the scalar product of electric flux intensity and vector area.

The electric field is the field, which is surrounded by the electric charged. The electric field is the electric force per unit charge.

The electric flux can be given as,

[tex]d\phi =\vec E \;dA\cos \theta[/tex]

When angle is zero,

[tex]d\phi =\vec E \;dA\times1\\d\phi =\vec E \;dA[/tex]

Thus, the total flux is,

[tex]\phi=\oint_{}^{}\vec E.d\vec A[/tex]

Thus, the relation between the electric intensity and electric flux is that the electric flux is equal to the scalar product of electric flux intensity and vector area.

Explanation:

You don't have the graph, but I know what question you are talking about. The answer is above.

The new gravitational potential energy of the three-sphere system will  be[tex]- \frac{5Gm^2}{r}[/tex].

The energy that an item has due to its location in a gravitational field is known as gravitational potential energy.

For the sphere 1 we have to perform no work. Hence, the work done is zero.

[tex]\rm W_1 = 0[/tex]

The mass m is to be brought to be infinity. Because there is potential at B due to mass m at A point .

[tex]\rm W_2 = \frac{-Gm}{r} \times m \\\\ W_2 =-\frac{Gm^2}{r}[/tex]

The B2 m at C is brought to infinity. For we have to do work . The  gravitational potential energy for the mass 2 m is;

[tex]\rm W_3 = \frac{-Gm}{r} \times 2m\\\\ W_3 = \frac{-4Gm^2}{y} \\\\[/tex]

The new gravitational potential energy of the three-sphere system will be;

[tex]\rm W =W_1+W_2+W_3 \\\\\rm W =-0-\frac{Gm}{r}-4\frac{-Gm^2}{r^2} \\\\ W=\-\frac{-5Gm^2}{r^2}[/tex]

Answer:

large membrane enclosed structure

Step-by-step explanation :

Here we just need to see the resistors which are connected in series combination. (Remember that you need not to use the potential difference in this question because we aren't asked to calculate the current).

As we know that,

>> Rs = 50 + 100

>> Rs = 150Ω

Therefore,

The value of potential energy stored in the spring when the block is 6. 20 cm from equilibrium is 1.65 J.

The elastic potential energy is the energy which is stored in a stretched spring. The elastic potential energy of a spring can be found by the following formula.

[tex]U_s=\dfrac{1}{2}kx^2[/tex]

Here, (k) is spring constant and (x) is the displacement of the spring.

The block is pulled to a position xi = 6. 20 cm from equilibrium and released. Thus,

[tex]x=6.20\rm \; cm[/tex]

Divide with 100 to convert its unit in meter,

[tex]x=0.062\rm \; m[/tex]

Let the value of spring constant is 860 N/m. Thus, put the values in the formula,

[tex]U_s=\dfrac{1}{2}kx^2\\U_s=\dfrac{1}{2}(860)(0.062)^2\\U_s=1.65\rm\; J[/tex]

Thus, the value of potential energy stored in the spring when the block is 6. 20 cm from equilibrium is 1.65 J.

A ray of monochromatic light passes from medium X into air. The refractive index of medium X is 1.52.

It states that the ratio of sine of angle of incidence and angle of refraction is equal to the refractive index of second medium to the first medium.

sini/sinr = n₁/n₂

Given the angle of incidence i = 25 degrees, angle of refraction r =40 degrees, refractive index of air n₁ =1, then  refractive index of medium X is

n₂ = 1 x sin 40/sin25

n₂ = 1.52

Thus, the refractive index of medium X is 1.52.

The magnitude and sign of the second charge will be + 8.6241×10⁻¹⁹ C. The principal of the Columb's law is used in the given problem.

The force of attraction between two charges, according to Coulomb's law, is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.

Charges that are similar repel each other, whereas charges that are diametrically opposed attract each other.

They will repel, moving in opposite directions at the same speed. Because the magnitude and nature of the charge are the same.

The given data in the problem is;

q₁  is the charge 1 = 4.4 nC = 4.4 ×10⁻⁹ C

F is the repulsive force = 36 mN =36 ×10⁶ N

d is the distance = 0.70 m

The Coulomb force is found as;

[tex]\rm F = \frac{Kq_1q_2}{r^2}\\\\\ \rm 36\times 10^6 = \frac{9 \times 10^9 }{(0.7)^2} \times 4.4 \times 10^{-9} \times q_2\\\\\ q_2 = 8.6241 \times 10^{-19 } \ C[/tex]
