How long is a true day? 23 hours and 56 minutes How many degrees does the Earth turn in 24 hours? 360 How many degree make an hour? 15 degrees How many degrees does the Earth turn in two days? While the Earth is rotating on its axis it is also moving along its orbit […]
What is the most slippery metal?
What is the most slippery metal? In fact, the low static coefficient of fric- tion of Teflon-on-Teflon, 0.04, made it the most slippery solid substance on earth. Further experimentation revealed the reasons for these properties: the carbon backbone of the polymer chain was com- pletely surrounded by fluorine atoms. Why is friction less on snow […]
What happens if one of the cars collided with more force than the other one?
What happens if one of the cars collided with more force than the other one? Forces between two colliding objects It doesn’t matter if one car is heavier (more massive) than the other. The push force from one car will equal the push force from the other. What happens to the energy when two objects […]

What element has an electron configuration of 1s 2 2s 2 2p 5?
What element has an electron configuration of 1s 2 2s 2 2p 5? fluorine How do you figure out the electron configuration? To calculate an electron configuration, divide the periodic table into sections to represent the atomic orbitals, the regions where electrons are contained. Groups one and two are the s-block, three through 12 represent […]
What operates best under bright light conditions?
What operates best under bright light conditions? The fovea contains cones that possess high levels of visual acuity and operate best in bright light conditions. What is the process of receiving stimulus energies? The process of receiving stimulus energies from the external environment and transforming those energies into neural energy is called SENSATION. The process […]
Does frequency increase with tension?
Does frequency increase with tension? Increasing the tension increases the wave speed so the frequency increases. What is the fundamental frequency of the string? The lowest resonance frequency (n=1) is known as the fundamental frequency for the string. All the higher frequencies are known as harmonics – these are integer multiples of the fundamental frequency. […]
What happens if you remove one bulb in a series circuit?
What happens if you remove one bulb in a series circuit? In a series circuit, every device must function for the circuit to be complete. One bulb burning out in a series circuit breaks the circuit. In parallel circuits, each light has its own circuit, so all but one light could be burned out, and […]
What motion is illustrated by a ball thrown horizontally?
What motion is illustrated by a ball thrown horizontally? Objects experiencing projectile motion have a constant velocity in the horizontal direction, and a constantly changing velocity in the vertical direction. The trajectory resulting from this combination always has the shape of a parabola. What are the standard assumptions we make for horizontally launched projectiles? Assumptions […]
How do you tell if a capacitor has failed?
How do you tell if a capacitor has failed? Use the multimeter and read the voltage on the capacitor leads. The voltage should read near 9 volts. The voltage will discharge rapidly to 0V because the capacitor is discharging through the multimeter. If the capacitor will not retain that voltage, it is defective and should […]
