What does the slope of velocity time graph represent?
What does the slope of velocity time graph represent? The slope of a velocity graph represents the acceleration of the object. So, the value of the slope at a particular time represents the acceleration of the object at that instant. Can you draw a graph for uniform motion? Distance-Time Graph for Uniform Motion Let’s draw […]
What did Harry Harlow find when he gave monkeys raised in isolation the choice of cloth covered or wire substitute mothers?
What did Harry Harlow find when he gave monkeys raised in isolation the choice of cloth covered or wire substitute mothers? In both conditions, Harlow found that the infant monkeys spent significantly more time with the terry cloth mother than they did with the wire mother. When only the wire mother had food, the babies […]
What causes the centrifugal force effect?
What causes the centrifugal force effect? chk – Centrifugal Force Caused by Inertia. When you swing an object around on a string or rope, the object will pull outward on the rope. The force you feel is called the centrifugal force and is caused by the inertia of the object, where it seeks to follow […]
What is total internal reflection simple definition?
What is total internal reflection simple definition? Total internal reflection, in physics, complete reflection of a ray of light within a medium such as water or glass from the surrounding surfaces back into the medium. The phenomenon occurs if the angle of incidence is greater than a certain limiting angle, called the critical angle. What […]

The sun What type of organisms can use the energy from the sun to make their own food? Most autotrophs use a process called photosynthesis to make their food. In photosynthesis, autotrophs […]
What is electrostatic screening length?
What is electrostatic screening length? Within the classical mean-field theories that explain screening and interactions in dilute electrolytes,(1) the Debye length, λD, is the yardstick against which the reach of electrostatic interactions in solution is typically measured. What is screening in cable? The screen is often directly placed over the insulated cores or pairs inside […]

What are the three properties of metalloids?
What are the three properties of metalloids? Physical properties of metalloids are as follows: ▪️Metalloids have a solid state of matter. ▪️In general, metalloids have a metallic luster. Metalloids have low elasticity, they are very brittle. ▪️Middleweights are semi-conducted elements, and they allow leave the average transmission of heat. Is sulfur dull or shiny? Appearance […]
Is Rain high or low pressure?
Is Rain high or low pressure? Generally high pressure means fair weather, and low pressure means rain. Is low pressure hot or cold? Cold, dense air squeezes its way through the warmer, less-dense air, and lifts the warm air. Because air is lifted instead of being pressed down, the movement of a cold front through […]
