How do you hand signal a right turn? For right turns, extend your left arm out the driver’s window with your elbow bent and point your hand to the sky with your palm facing forward. Again, it’s best to keep your arm in this position until you begin your right turn, just as you would […]

What happens to air pressure as altitude decreases quizlet? As air pressure decreases altitude increases. As air pressure decreases so does density. What happens to air pressure and density as altitude increases? Altitude and Density The density of air decreases with height. There are two reasons: at higher altitudes, there is less air pushing down […]

How does the apple taste? The flesh is slightly crunchy, but easily gives way. The skin is edible — but flavorless. The apple itself has a distinct flavor making it an apple flavor. It’s a little sour and bitter, but mostly sweet, not at all salty, very juicy in general. What is the color of […]

Which element has a mass of 24? Chromium Why are lanthanides Coloured? Lanthanides or more precisely lanthanides ions are coloured mainly because of their partly filled f orbitals. This allows a certain wavelength from the visible region of the spectrum to be absorbed which leads to the formation of f-f transition. Is lanthanides are Colourless? […]

What is the force on a current carrying conductor? The force on a current-carrying wire in a magnetic field is F = IlB sin θ. Its direction is given by RHR-1. What is the force on a current carrying wire that is parallel? Force on a current-carrying wire that is parallel to the magnetic field […]

Is jumping a normal force? When we jump, the chemical energy in our muscles get converted to kinetic energy that exerts a force on the ground (that using Newton’s 3rd law), will trigger a reaction that will ‘push’ us up- and thus a jump. This resultant normal force = Mass x Distance of jump. Is […]

Which star has the shortest lifespan? red dwarfs Which star has the longest life? The stars with the longest lifetimes are red dwarfs; some may be nearly as old as the universe itself. Red Dwarf Stars. Astronomers define a red dwarf as a star having between about 0.08 and 0.5 times the mass of the […]

Does specific heat depend on temperature? Therefore specific heat does not depend on temperature. What are the three factors affect the heat transfer that is necessary to change an object’s temperature? Experiments show that the transferred heat depends on three factors—the change in temperature, the mass of the system, and the substance and phase of […]

What is the difference between tables charts and graphs? Same, but Different Charts present information in the form of graphs, diagrams or tables. Graphs show the mathematical relationship between sets of data. Graphs are one type of chart, but not the only type of chart; in other words, all graphs are charts, but not all […]

Which is an example of liquid glass thermometer? Mercury Thermometers This type of thermometer was developed by a German based physicist named Daniel Gabriel Fahrenheit. It consists of mercury as a liquid filled in a glass tube. On the body of the glass tube, calibrated marks are provided which facilitates the reading of temperature. How […]
