Ionic bonds <span>are the type of bonds where there is </span>transfer<span> of electrons from one atom to another. The electrons are removed and from one atom and attached to another. A good example is salt which is composed of sodium and chlorine. Sodium readily loses one of its electrons and chlorine readily accepts it. Before losing the electron, sodium has a positive charge, but then becomes negatively charged after giving up the electron. Chlorine has a positive charge before gaining the electron but becomes negatively charged after gaining the electron. These opposite charges between sodium and chlorine attract the two elements together to form the ionic bond.</span>
Answer: has wavelengths that are longer than visible light
Explanation: Electromagnetic spectra comprises of different electromagnetic waves which are arranged in order of increasing wavelengths or decreasing energies.
In order from highest to lowest energy, the waves are arranged as: gamma rays, X-rays, ultraviolet radiation, visible light, infrared radiation, and radio waves.
E= energy
h= planck's constant
c= velocity of light
= wavelength
As wavelength and energy are inversely related, the wave having higher wavelengths will be lowest in energy. Thus as infrared radiation have lower energy as compared to visible radiation. Thus infrared radiation have higher wavelength as compared to visible radiation.
The angular velcoity of this cylinder when the downward speed of the elevator is 1.2 m/s would be 6 rad/s.
<u>Given the following data:</u>
Radius of cylinder = 0.20 meter.
Linear velocity = 1.2 m/s.
<h3>What is angular velocity?</h3>
Angular velocity can be defined as the rate of change of angular displacement of an object with respect to time. Thus, it is a measure of how fast and quickly an object revolves or rotates relative to another point or how its angular position changes with respect to time.
<h3>The formula for angular velcoity.</h3>
Mathematically, angular velcoity is given by this formula:
Substituting the given parameters into the formula, we have;
Angular velocity = 6 rad/s.

When a pendulum swings, potential energy is transformed into kinetic energy, and then back again to potential energy as the speed and elevation of the pendulum vary during the motion
This feather weighs heavier on earth than on Mars hence it is better that the feather falls on you in Mars than on earth.
<h3>What is weight?</h3>
The term weight refers to the effect of the gravitational pull on an object. The acceleration due to gravity on earth is about 9.8m/s^2. The weight of this feather on earth is about 4.80 Kg * 9.8m/s^2 = 47 N
On the planet Mars, the weight is;
4.80 Kg * (0.38 * 9.8m/s^2) = 18 N
This feather weighs heavier on earth than on Mars hence it is better that the feather falls on you in Mars than on earth.
