What is one difference between a total solar and a total lunar eclipse? During a total solar eclipse, the moon passes between Earth and the sun, casting a small, dark shadow on our planet. During a lunar eclipse, however, the Earth passes between the moon and the sun, casting its shadow — known as the […]

What is a quantized value?
What is a quantized value? Quantized: In quantum mechanics, the concept that a system cannot have any possible energy value but instead is limited to certain specific energy values (states). The states depend on the specific system in question. How is a piano An example of a quantized system? When you play a piano, you […]
What are two ways to increase kinetic energy?
What are two ways to increase kinetic energy? If you double the mass of an object, you double the kinetic energy. If you double the speed of an object, the kinetic energy increases by four times. The word “kinetic” comes from the Greek word “kinesis” which means motion. Kinetic energy can be passed from one […]
What will be my mass if my weight is 50 kg?
What will be my mass if my weight is 50 kg? However, WEIGHT does vary given the gravitational well. A mass of 50⋅kg has a WEIGHT of 50⋅kg×9.81⋅N⋅kg−1=490.5⋅N on the earth, but a weight of 50⋅kg×1.622⋅N⋅kg−1=81.1⋅N on the moon…… What is a healthy weight for a 4 11 female? Height and Weight Chart Height Weight […]
Why does temperature increase as pressure increases?
Why does temperature increase as pressure increases? The temperature of the gas is proportional to the average kinetic energy of its molecules. Faster moving particles will collide with the container walls more frequently and with greater force. This causes the force on the walls of the container to increase and so the pressure increases. What […]

How can I improve my balloon powered car?
How can I improve my balloon powered car? How to Make a Balloon Car Go Faster Reduce Weight. Examine your car carefully for any opportunity to shed as much weight as possible. Minimize Drag. Drag, or air resistance, is important even at low speeds because the balloon car is so lightweight. Cut the Friction. Improve […]

What is the best evidence in the text for the prediction that Champollion will eventually figure out the T hieroglyph? The only hieroglyph that confused Champollion was the one for “T,” which was different in the two names. What is the best evidence in the text for the prediction that Champollion will eventually figure out […]
