What would happen if we turned off all the lights in the world? As a result, they would emit even more CO2! And this extra carbon waste would start to trap more heat in our lower atmosphere, possibly speeding up climate change. And that’s if power plants were able to cope with such a rapid […]
How do you take off a percentage?
What is the most aggressive color?
What is the most aggressive color? Red. This is the color of aggression and passion—great for a first date, not so great for the office. It also increases metabolism and raises blood pressure, which is why it’s used for stop signs and fire engines. Why is purple an evil color? Purple. As we anticipated, purple […]
What is the main energy transfer that takes place in a loudspeaker?
What is the main energy transfer that takes place in a loudspeaker? Whereas a microphone converts the movements of its diaphram due to sound energy into electrical signals, loudspeakers convert electrical energy into motion of the diaphram and thus into sound energy. What form of energy is the fan blades spinning? A fan converts mechanical […]
What are three factors that affect weathering?
What are three factors that affect weathering? Rainfall and temperature can affect the rate in which rocks weather. High temperatures and greater rainfall increase the rate of chemical weathering. 2. Rocks in tropical regions exposed to abundant rainfall and hot temperatures weather much faster than similar rocks residing in cold, dry regions. What are factors […]
Is Earth inertial or non-inertial?
Is Earth inertial or non-inertial? As the earth performs circular motion about its axis, it must have acceleration so it is non-inertial frame of reference. What is the difference between inertial frame and non-inertial frame? Distinguish between inertial and noninertial frames of reference….Solution. Inertial frame of reference Non-inertial frame of reference 3. The body does […]
Why can you calculate the experimental value of the moment of inertia?
Why can you calculate the experimental value of the moment of inertia? Why are you able to calculate the experimental value of the moment of inertia of the ring in the manner you did? Because both bodies had the same common axis of torsion, their moment of inertia is the sum of each individual body […]
What are the rules for drawing magnetic field lines?
What are the rules for drawing magnetic field lines? Magnetic fields can be pictorially represented by magnetic field lines, the properties of which are as follows: The field is tangent to the magnetic field line. Field strength is proportional to the line density. Field lines cannot cross. Field lines are continuous loops. How do you […]
Why are valleys so windy?
What happens to kinetic energy when an object slows down?
What happens to kinetic energy when an object slows down? A moving object can slow down for different reasons. One is because of friction and another one would be because it slows down, if you throw it up into the air for instance. Both objects are slowing down and therefore their kinetic energy decreases. So, […]
