Why is a balance of water important for the growth of plants? Water helps a plant by transporting important nutrients through the plant. Nutrients are drawn from the soil and used by the plant. Without enough water in the cells, the plants droop, so water helps a plant to stand. Water carries the dissolved sugar […]

What color is high pressure on a weather map?
What color is high pressure on a weather map? blue What does a high pressure look like on a weather map? Atmospheric pressure is measured with an instrument on the ground called a barometer, and these measurements are collected at many locations across the U.S. by the National Weather Service. On weather maps, these readings […]

How do you tell if glasses are too strong or too weak?
What is commutator and its function?
What is commutator and its function? The commutator assures that the current from the generator always flows in one direction. On DC and most AC motors the purpose of the commutator is to insure that the current flowing through the rotor windings is always in the same direction, and the proper coil on the rotor […]
What does N m2 stand for?
What does N m2 stand for? Newton per Square Metre How many kg are in a m2? 1000 kg How do I calculate m2? Multiply the length and width together. Once both measurements are converted into metres, multiply them together to get the measurement of the area in square metres. How do you calculate area […]
What happens to the movement of molecules when their temperature is raised?
What happens to the movement of molecules when their temperature is raised? Particles move rapidly in all directions but collide with each other more frequently than in gases due to shorter distances between particles. With an increase in temperature, the particles move faster as they gain kinetic energy, resulting in increased collision rates and an […]
How cold is solid neon?
How cold is solid neon? Though neon is about 31/2 times as plentiful as helium in the atmosphere, dry air contains only 0.0018 percent neon by volume. This element is more abundant in the cosmos than on Earth. Neon liquefies at −246.048 °C (−411 °F) and freezes at a temperature only 21/2° lower. What does […]
What is transferred when work is done?
What is transferred when work is done? Work is the measure of energy transfer when a force (F) moves an object through a distance (d). So when work is done, energy has been transferred from one energy store to another, and so: energy transferred = work done. What is the common formula for work? Work […]
