If you mean in mass, then the mass of one proton is approximately equal to the mass on one neutron. If you mean how many of each, then the number of protons is equal to the number of electrons. If the number of electrons was different from the number of protons, then you'd have an ion. An ion with a positive charge is a cation, and an ion with a negative charge is an anion.

A wire of cross-sectional area 5.00 106 m2 has a resistance of 1.75 O. What is the resistance of a wire of the same material and
MakcuM [25]

Answer:

the resistance of the second wire is 1 ohm.

Explanation:

Given;

cross sectional area of the first wire, A₁ = 5.00 x 10⁶ m²

resistance of the first wire, R₁ = 1.75 ohms

cross sectional area of the second wire, A₂ = 8.75 x 10⁶ m²

resistance of the second wire, R₂ = ?

The resistance of a wire is given as;

R ∝ \frac{L}{A}

Since the length of the two wires is constant

R₁A₁ = R₂A₂

R_2 = \frac{R_1A_1}{A_2} \\\\R_2 = \frac{1.75\  \times \ 5.00\times 10^6}{8.75\times 10^6} \\\\R_2 = 1 \ ohm

Therefore, the resistance of the second wire is 1 ohm.

A flash of red light and a flash of blue light enter a glass cube perpendicular to its surface at the same time. after passing t
Wewaii [24]

A flash of red light and a flash of blue light enter a glass cube perpendicular to its surface at the same time. after passing through the block, the red light pulse exits first.

For any medium, other than vacuum, the index of refraction for red light is slightly lower (closer to 1 ) than that for blue light. This means that when light goes from vacuum (or air) into glass, the red light deviates from its original direction less than does the blue light. Also, as the light reemerges from the glass into vacuum (or air), the red light again deviates less than the blue light. If the two surfaces of the glass are parallel to each other, the red and blue rays will emerge traveling parallel to each other, but displaced laterally from one another.

what is refractive index?

The ratio between the speed of light in medium to speed in a vacuum is the refractive index. When light travels in a medium other than the vacuum, the atoms of that medium continually absorb and re-emit the particles of light, slowing down the speed light.

The microwave in your kitchen operates at 2,358,000 Hz. If the speed of light is 300,000,000 m/s, what is the wave’s wavelength?
Novosadov [1.4K]

Answer:

wavelength = speeed / frequency

= 300,000,000 / 2358000

= 300 / 2.358

= 127.2 m
