Microwaves have a little more energy than radio waves.

Explanation:

The prior difference between a radio wave and microwave is that the microwave has a shorter wavelength as compared to radio wave.

Hopefully this helps you!

An electrical charge is created when electrons are transferred to or removed from an object. Because electrons have a negative charge, when they are added to an object, it becomes negatively charged. When electrons are removed from an object, it becomes positively charged

Answer:

-5Gm^2/r

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]

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

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]

Hence, the magnitude and sign of the second charge will be + 8.6241×10⁻¹⁹ C.

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 energy of a photon with a wavelength of 245 nm will be 8.08 ×10⁻¹⁹ J. De Broglie relation is used to find out the energy.

The distance between two successive troughs or crests is known as the wavelength. The peak of the wave is the highest point, while the trough is the lowest.

The relationship between the wave's wavelength,energy is;

[tex]\rm E = \frac{hc }{\lambda} \\\\ \rm E = \frac{6.6 \times 10^{-34} \times 3 \times 10^8}{245 \times 10^{-9}} \\\\ \rm E=8.08 \times 10^{-19}\ J[/tex]

The representation of a chemical reaction in the form of substances is known as a chemical equation. The equation in which the number of atoms of all the molecules is equal on both sides of the equation is known as a balanced chemical equation.

The Law of conservation of mass governs the balancing of a chemical equation.

According to this law, mass can neither be created nor be destroyed in a chemical reaction and obeying this law total mass of the elements or molecules present on the reactant side should be equal to the total mass of elements or molecules present on the produc

Explanation:

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.
