Which of the following factors does not affect the movement of ocean water? Which of the following factors does not affect the movement of ocean water? Temperature. Salinity. How temperature affects the movement of ocean water? Water expands when it warms up – heat energy makes its molecules move around more and take up more […]

Why is it easier for humans to walk through air than liquid water? It is easier to push an object through air than through water. This is because air is less dense than water. Since air is less dense this means there is less matter, or less “stuff”, in a certain area of air than […]

Can you fail fifth grade? Will I fail the 5th grade? No, you won’t fail 5th grade. But honestly, you may be missing the point. If you made an F in math, you really need to find out why and correct your performance. What age are 5th graders? 10 years old Can a 12 year […]

Which sentence best describes mass movement? The downhill flow of soil and rock resulting from gravity best describes mass movement. The downhill flow of soil and rock resulting from gravity best describes mass movement. Which type of mass movement occurs when a fragment of rock breaks off and drops almost vertically to the ground below […]

What is the chemical name of ch2? Methylene Why is CH2 called methylene? Methylene was used as the name for methanol, which is wood alcohol, CH3OH, in the early 19th century. Methylene comes from methe + hyde the latter being the Greek word for wood, so methylene would mean wine from wood. What is full […]

Can aluminum be magnetized? In our everyday experience aluminum doesn’t stick to magnets (neither does copper). Most matter will exhibit some magnetic attraction when under high enough magnetic fields. But under normal circumstances aluminum isn’t visibly magnetic. Why is stainless steel jewelry so cheap? Stainless steel not only mimics the look of fine, precious metal, […]

What is negative acceleration called? The other name of negative acceleration is Retardation or Deceleration. A deceleration is opposite to the acceleration. The deceleration means the decrease in the speed of body/object movement. What is negative acceleration in simple words? According to our principle, when an object is slowing down, the acceleration is in the […]

What is the direction of the electric field in the rod? The direction of the electric field is always directed in the direction that a positive test charge would be pushed or pulled if placed in the space surrounding the source charge. Since electric field is a vector quantity, it can be represented by a […]

Why does sand burn your feet? Yes, the sand heats up in the hot sun and is a common cause of burns on your feet. When it is 90 degrees outside, the sand can be over 120 degrees, hot enough to cause second and even third degree burns. So at the beach, wear Crocs, aqua […]

Does Salt raise boiling temp of water? When salt is added, it makes it harder for the water molecules to escape from the pot and enter the gas phase, which happens when water boils, Giddings said. This gives salt water a higher boiling point, she said. “The temperature of saltwater will get hotter faster than […]
