How do you find the change in temperature? You subtract the final temperature from the starting temperature to find the difference. So if something starts at 50 degrees Celsius and finishes at 75 degrees C, then the change in temperature is 75 degrees C – 50 degrees C = 25 degrees C. Which does not […]

What cause the plates to move? The heat from radioactive processes within the planet’s interior causes the plates to move, sometimes toward and sometimes away from each other. This movement is called plate motion, or tectonic shift. How does temperature change as you go deeper into the earth? The Earth gets hotter as one travels […]

Is there a number C in the closed interval? “If f is continuous on a closed interval [a, b], and c is any number between f(a) and f(b), then there is at least one number x in the closed interval such that f(x) = c”. It is a continuous function because it is a polynomial […]

What can President do without Senate approval? declare war. decide how federal money will be spent. interpret laws. choose Cabinet members or Supreme Court Justices without Senate approval. Can the president do anything without Congress approval? Executive powers The president can issue rules, regulations, and instructions called executive orders, which have the binding force of […]

What is the example of vector quantity? For example, displacement, velocity, and acceleration are vector quantities, while speed (the magnitude of velocity), time, and mass are scalars. To qualify as a vector, a quantity having magnitude and direction must also obey certain rules of combination. Why is distance not a vector? Distance is a scalar […]

Can LED light cause fire? LED lights do not emit light from a vacuum as most other bulb types do. Overheating is one of the reasons a bulb could start a fire, but that is highly unlikely to happen with LED lights. They may feel hot to touch, but they produce light at a significantly […]

Does momentum determine whether the egg breaks? B. Does the car’s momentum determine whether the egg breaks? Yes C. How does potential energy change when mass is increased? The amount of gravitational potential energy an object has depends on its height and mass. The heavier the object and the higher it is above the ground, […]

How many calories should I consume to lift 1 kg? It takes ~ 240 calories to raise or lift 100 kilograms 1 meter. Human energy calories are always kilocalories. If you wanted to burn 1000 (k)calories, you’d have to bench press 100kg about 830 reps. How many calories do you burn in 2 hours of […]

What are the 8 emotions we are born with? Eight Primary Emotions Sadness: grief, sorrow, gloom, melancholy, despair, loneliness, and depression. Fear: anxiety, apprehension, nervousness, dread, fright, and panic. Joy: enjoyment, happiness, relief, bliss, delight, pride, thrill, and ecstasy. How many emotions are there 2020? A more recent study suggests that there are at least […]

Which is faster rolling or sliding? Since the sliding object has no angular velocity, its linear velocity is greater than that of the rolling object, and it reaches the bottom of the track faster. And if C < μk, the rolling object has a greater linear acceleration and wins the race to the bottom. What […]
