What is the final velocity of the two vehicle mass? A 1500 kg car traveling at 15 m/s to the south collides with a 4500 kg truck that is intially at rest at a spotlight. The car and the truck stick together and move together after the collison. Therefore, the final velocity of the two-vehicle […]

When two or more systems are in thermal equilibrium with each other they will have the same temperature? In other words, if two objects are in thermal equilibrium, they have the same temperature. If thermometer A is in thermal equilibrium with object B, and B is in thermal equilibrium with C, then A is in […]

What is time period of a simple pendulum? The time period of a simple pendulum: It is defined as the time taken by the pendulum to finish one full oscillation and is denoted by “T”. Length of a simple pendulum: It is defined as the distance between the point of suspension to the centre of […]

What is the volume of 1 drop of blood? about 61.6 μL How much blood do you make a day? The average healthy adult produces anywhere from 400 to 2,000 milliliters a day. Or on average, 34,400 liters in a lifetime. That’s enough to fill 46 hot tubs, gross. Now, that might seem impressive, but […]

What is a scientific principle examples? If you drop an apple, it will fall. If you throw an apple in the air, it will follow a specific path while falling down. Newton’s laws don’t tell us why the apple falls or what causes it to fall, just that it does fall. Similarly, the law of […]

How are biochemical sedimentary rocks classified? Sedimentary rocks are classified based on how they form and on the size of the sediments, if they are clastic. Clastic sedimentary rocks are formed from rock fragments, or clasts; chemical sedimentary rocks precipitate from fluids; and biochemical sedimentary rocks form as precipitation from living organisms. What is a […]

What heart rate should I aim for when running? You can determine your target heart rate for running using a formula based on your age and maximum heart rate. When running, you should train at 50 to 85 percent of your maximum heart rate. To calculate the maximum rate, subtract your age from 220. What […]

Are anode rays deflected by electric field? Anode rays are deflected by electric and magnetic fields but in a direction opposite to that of cathode rays. Why are they called cathode rays? Eugen Goldstein coined the term cathode rays in 1876. They were called cathode rays because they were emitted from the cathode of the […]
