Does voltage stay the same in series?
Does voltage stay the same in series? 2. In a series circuit the current is the same at any particular point on the circuit. 3. The voltage in a series circuit, however, does not remain constant. Why does voltage decrease in a series circuit? In series circuits, the resistor with the greatest resistance has the […]
Why does massless light bend near a large mass?
Why does massless light bend near a large mass? Light can form a curve if it travels near a big mass. You are right, photons don’t have mass. You are also right, photons doesn’t follow Newton’s gravitation law. Photons can be pulled by gravity not because of their mass (they have none) but because gravity […]
How does speed affect projectile motion?
How does speed affect projectile motion? Because air resistance affects the horizontal component of a projectiles trajectory, the effect of it can be minimized by lowering the angle of release. Speed or velocity is directly related to distance. The greater the speed of release, the greater the distance covered in flight. Initial Horizontal Velocity. How […]
What are 4 examples of mechanical weathering?
What are 4 examples of mechanical weathering? Examples of mechanical weathering include frost and salt wedging, unloading and exfoliation, water and wind abrasion, impacts and collisions, and biological actions. All of these processes break rocks into smaller pieces without changing the physical composition of the rock. What are the 7 types of mechanical weathering? Types […]
What causes changes in seasons?
How do you know if a graph is direct or inverse?
How do you know if a graph is direct or inverse? Numerically: Direct Variation: Because k is positive, y increases as x increases. So as x increases by 1, y increases by 1.5. Inverse Variation: Because k is positive, y decreases as x increases. Is addition and subtraction inverse relationship? Addition and subtraction are inverse […]
What are the selection rules for vibrational transitions?
What are the selection rules for vibrational transitions? Thus, the selection rule for a harmonic oscillator transition is ∆v = ± 1. The physical meaning of the vibrational selection rule is this: The vibration must change the molecular dipole moment to have a non-zero (electric) transition dipole moment. Which transition between rotational energy levels is […]
How do you check the oxygen level in an aquarium?
How do you check the oxygen level in an aquarium? The best way to test the amount of dissolved oxygen in your aquarium’s water is with a portable dissolved oxygen meter. After calibrating the meter, you can place a probe into the tank water, and read the results on the digital display. How do you […]
At what altitude do you become weightless?
At what altitude do you become weightless? Any object that is falling freely is weightless, no matter where it happens to be. This can be the International Space Station at a height of 200 miles, a NASA reduced-gravity airplane at a height of several thousand feet, a drop tower at several hundred feet, or you […]
