What is the angle between acceleration and velocity at the highest point? 90∘ What is the angle between the velocity and acceleration vectors at these times? It depends on the system which you are working on. If the motion is circular then the angle between velocity vector and acceleration is 90°. At what point of […]

What is the meaning of career cluster? A career cluster is group of careers that share common features. If you like one job in a cluster, you will probably find other jobs in that cluster that you will like as well. Here are examples of three different career clusters. Health — Workers in this cluster […]

What is the formula of simple harmonic motion? For a simple harmonic oscillator, an object’s cycle of motion can be described by the equation x ( t ) = A cos ⁡ ( 2 π f t ) x(t) = A\cos(2\pi f t) x(t)=Acos(2πft)x, left parenthesis, t, right parenthesis, equals, A, cosine, left parenthesis, 2, […]

Does using oxygen make your lungs weaker? Unfortunately, breathing 100% oxygen for long periods of time can cause changes in the lungs, which are potentially harmful. Researchers believe that by lowering the concentration of oxygen therapy to 40% patients can receive it for longer periods of time without the risk of side effects. How many […]

What are the 5 largest moons of Jupiter? ESA Science & Technology – Jupiter’s largest moons From top to bottom, the moons are Io, Europa, Ganymede and Callisto. Europa is almost […]

What is a small smooth stone called? Small smooth stones (7) PEBBLES. What do you call a small piece of wood or stone? A splinter is a narrow, pointed sliver that breaks off something larger. We often use the word splinter to refer to tiny shards of wood that lodge under the skin, but a […]

How is power delivered calculated? The power delivered by the voltage source is: PV = – I * V = – 5 * 10-2 *150 = -7.5 W. Note that the current is opposite to the voltage in the source. By convention in this case, power is denoted as a negative quantity. Is Power conserved […]

When siliceous ooze Lithifies it is called? When a coccolithophore dies, the individual plates (called coccoliths) disaggregate and can accumulate on the ocean floor as coccolith-rich ooze. When this ooze lithifies over time, it forms chalk. Which kind of ooze is found deepest? Carbonate oozes What happens below the CCD? The carbonate compensation depth, or […]

Would the local wind change if it was nighttime quizlet? Answer: The direction of winds changes at night especially in coastal areas. How does the sun cause wind? When the Earth’s surface absorbs the sun’s energy, it turns the light into heat. This heat on the Earth’s surface warms the air above it. This moving […]

What happens when an air bubble enters the bloodstream? When an air bubble enters a vein, it’s called a venous air embolism. When an air bubble enters an artery, it’s called an arterial air embolism. These air bubbles can travel to your brain, heart, or lungs and cause a heart attack, stroke, or respiratory failure. […]
