Why it is important to follow policies and procedures? Policies and procedures are an essential component of any organization. Policies address pertinent issues, such as what constitutes acceptable behavior by employees. Procedures clearly define a sequence of steps to be followed in a consistent manner, such as how the organization will respond to any policy […]
What are the two main studies of physical science?
What are the two main studies of physical science? In this lesson, we will discuss how physics and chemistry are considered to be the two main branches of physical science. We will also look at the overlap between physics and chemistry. What are the issues in science education? Some of the complex issues in the […]
What is the frequency of red?
What is the frequency of red? The visible spectrum colour* wavelength (nm) frequency (1014 Hz) red 650 4.62 orange 600 5.00 yellow 580 5.16 green 550 5.45 Which of the color has the highest frequency and energy? violet Does red light travel further than blue? The individual components of light are called the spectrum. Blue […]
What front usually happens and is over quickly?
What front usually happens and is over quickly? Occluded Front Because cold fronts move faster, the cold front is likely to overtake the warm front. This is known as an occluded front. At an occluded front, the cold air mass from the cold front meets the cool air that was ahead of the warm front. […]
Why incandescent bulbs are better?
Why incandescent bulbs are better? Incandescent bulbs cost much less than their energy-efficient alternatives – mainly CFLs (compact fluorescent lamps) and LEDs (light emitting diodes). Incandescents are inefficient – 90% of the energy goes toward heat and only 10% toward light. Incandescents also don’t last as long as CFLs and LEDs. What are the disadvantages […]
What are the similarities and differences between fission and fusion?
What are the similarities and differences between fission and fusion? Both fission and fusion are nuclear reactions that produce energy, but the applications are not the same. Fission is the splitting of a heavy, unstable nucleus into two lighter nuclei, and fusion is the process where two light nuclei combine together releasing vast amounts of […]
Is thermal energy removed or added in boiling?
Is thermal energy removed or added in boiling? particles, rise to the top of the liquid and escape from the container. In the graph above, notice the energy changes that occur as thermal energy is added. The kinetic energy of particles increases until the liquid reaches its boiling point. At the boiling point, the potential […]
What color temperature is best for plants?
What color temperature is best for plants? As a general recommendation, choose a full spectrum grow light with a color temperature in the blue range (5,000 – 7,000K) to promote vegetative growth and choose a color temperature in the red range (3,500 – 4,500K) to promote fruiting and flowering. Visible Light Spectrum. Can plants grow […]
What are the 4 properties of the atom?
What are the 4 properties of the atom? Typical sizes of atom and nucleus. Most of atom’s mass is in the nucleus. Constituents: protons, neutrons, electrons. Electric force holds atom together. Nuclear force holds nucleus together. Atoms, ions. Atomic number. What are three examples of properties? These properties include color, density, melting point, boiling point, […]
What is an example of emergent literacy?
What is an example of emergent literacy? Examples of emergent literacy activities include engaging in shared storybook reading, pretending to write or draw, incorporating literacy themes into play, and engaging in oral wordplay such as rhyming. Parents read to children who are very young before they can verbally participate. What are the 5 pillars of […]
