Is a 1.4 Litre engine good for motorway? Frequent motorway trips If so, you’ll need an engine sized from 1.4 litres to 2.0 litres, because you’ll be on the motorway network a great deal. Bigger engines can better handle the rigours of the motorway – such as overtaking. How many cc is a 1.4 Litre […]

What is the semi major axis of Earth? 1.000 1 What is the value for eccentricity? orbital calculations For a perfectly circular orbit, the eccentricity is 0; with increasing elongation of the orbit’s shape, the eccentricity increases toward a value of 1, the eccentricity of a parabola. What is the eccentricity of a straight line? […]

What percentage of C 14 remains after 3 half lives? Explanation: After 1 half-life, 12 of the C-14 would remain. After 2 half-life, 12 of the 12 of the C-14 = 14 of the C-14 would remain. After 3 half-life, 12 of the 14 of the C-14 = 18 of the C-14 would remain. What […]

Who wins the tug of war with what net force? 3 Answers. The force on rope is equal for both of them at any time. For winning the game the force on ground is responsible. What force pulls an object back to Earth? Gravity Is gravity push or pull? In general relativity, gravity neither pushes […]

What is solid to a gas called? The solid-to-gas change is called sublimation, while the reverse process is called deposition. Sublimation is isothermal, like the other phase changes. There is a measurable energy change during sublimation; this energy change is called the enthalpy of sublimation, represented as ΔH sub. What are 3 examples of sublimation? […]

Is it harmful to reheat tea? First things first, do not reheat the tea if it has been left at room temperature for anywhere between 4 to 8 hours. If you forgot to have your tea for a maximum of 10 to 15 minutes, it is safe to drink. The presence of milk results in […]

Is it bad to look at IR light? All infrared, visible or ultraviolet electromagnetic radiation can cause injury to the eye in sufficient concentrations, but this is very rare. Infrared lamps and incandescent bulbs are not powerful enough to cause such harm. But it’s best if you don’t stare directly at them for too long. […]

Is it safe to eat iceberg ice? A: Iceberg ice is completely safe to consume. Q: Are icebergs salty? A: No. Icebergs are created from pure, fresh water and snow. What will happen if icebergs do not float? Unlike plants, animals can move so they would move as far as possible or be trapped and […]

What is the difference between membrane potential and resting potential? For a cell’s membrane potential, the reference point is the outside of the cell. Because there is a potential difference across the cell membrane, the membrane is said to be polarized. If the membrane potential becomes more positive than it is at the resting potential, […]

How do emotions affect our perception? Emotional arousal guides attention so that people’s attention tends to be drawn to objects that are arousing. As we shall see, some of the important influences of emotion on perception are mediated by attention, but emotion can also influence pre-attentive perceptual processes. How do emotions affect reality? Emotions drive […]
