Answer:

Particles of matter of the same substance, such as the same element, are attracted to one another. The force of attraction tends to pull the particles closer together. The particles need a lot of kinetic energy to overcome the force of attraction and move apart.

Which of the following are found within the electromagnetic spectrum? Check all that apply. sound waves visible light X rays ult

sattari [20]

Answer:

Visible light

X rays

ultraviolet radiation

gamma rays

microwave radiation

Explanation:

Electromagnetic waves consist of oscillating electric and magnetic fields which vibrate in a direction perpendicular to the direction of motion of the wave (transverse wave). Electromagnetic waves have all same speed in a vacuum ( $c=3.0\cdot 10^8 m/s$ , known as speed of light) and are classified into 7 different types according to their frequency and wavelength. This classification is called electromagnetic spectrum.

From lowest to highest wavelength, the 7 types are:

Gamma rays

X-rays

Ultraviolet radiation

Visible light

Infrared radiation

Microwaves

Radio waves

Sound waves, on the contrary, do not belong to the electromagnetic spectrum, since they are another type of wave called mechanical waves (which consist of vibrations of the particles in a medium).

Io maintains a constant orbit around Jupiter because

Free_Kalibri [48]

Answer: C . The gravitational pull from Jupiter is much greater than any other forces acting on Io.

Explanation:

Let's begin by the fact Jupiter is a huge massive planet, therefore the bodies that are closest to Jupiter will have a greater gravitational force than the other bodies. That is the situation with Io, the moon closest to Jupiter.

However, Io's orbit is very elliptical and eccentric compared to the outer moons, resulting in the distortion of its shape by the gravitational force. In fact, Io is considered the most geologically active object in the solar system, due to these variations.

When a potential difference of 10 V is placed across a certain solid cylindrical resistor, the current through it is 2 A. If the

DaniilM [7]

Answer:

Current would decrease 9 times.

Explanation:

Assume all others (potential difference U, resistivity ρ, and length L) are the same, only change in the diameter, we would have the following ratio

$\frac{I_1}{I_2} = \frac{U/R_1}{U/R_2} = \frac{U}{U}\frac{R_2}{R_1} = \frac{\rho L/A_2}{\rho L / A_1} = \frac{\rho L}{\rho L}\frac{A_1}{A_2} = \frac{\pi d_1^2/4}{\pi d_2^2/4} = \frac{4\pi}{4\pi}\left(\frac{d_1}{d_2}\right)^2 = 3^2 = 9$

$I_2 = I_1/9$

So the current would decrease 9 times.
