Does the Beagle ship still exist? It said no evidence of the Beagle itself has yet been found. Following the Beagle’s third and final exploratory voyage in 1843 it was refitted as a static watch vessel for the coastguard in 1845, until sold in 1870. Why was Darwin’s ship named Beagle? In 1837 HMS Beagle […]
Is Absolute Zero Possible?
Is Absolute Zero Possible? Absolute zero, technically known as zero kelvins, equals −273.15 degrees Celsius, or -459.67 Fahrenheit, and marks the spot on the thermometer where a system reaches its lowest possible energy, or thermal motion. There’s a catch, though: absolute zero is impossible to reach. How do you explain thermodynamics to a child? Thermodynamics […]
Are enzymes used up in a reaction?
Are enzymes used up in a reaction? Enzymes are not reactants and are not used up during the reaction. Once an enzyme binds to a substrate and catalyzes the reaction, the enzyme is released, unchanged, and can be used for another reaction. This means that for each reaction, there does not need to be a […]
What determines how much load a stream can carry?
What determines how much load a stream can carry? The ability of streams to carry a load is determined by 2 factors: Competence and Capacity. Competence of a stream measures the largest PARTICLES it can transport. A stream’s competence increases with it velocity. The competence of a stream increases 4 times-when the velocity doubles. What […]
How many steps are there in critical thinking?
How many steps are there in critical thinking? 5 steps What are the rules for critical thinking? 11 Rules for Critical Thinking All beliefs in whatever realm are theories at some level. Do not condemn the judgment of another because it differs from your own. Read not to contradict and confute; nor to believe and […]
What happens when a wave reflects off a fixed boundary?
What happens when a wave reflects off a fixed boundary? The right end is held tightly; it is a fixed end. The wave reflects off this fixed end and returns as a downward displaced pulse. Reflection off a fixed end results in inversion. At what angle does a reflected waves bounce back? In a reflection, […]
What are the seasonal effects of waves on beaches?
What are the seasonal effects of waves on beaches? The equilibrium beach profile results from steady wave forcing during the seasonal cycle. Summer wave conditions move sand onto the beach. Winter storm waves move sand offshore. Unusually large storm events result in a disequilibrium profile, and sand may be permanently lost to deep water. What […]
Why do asteroids and comets differ in composition group of answer choices?
Why do asteroids and comets differ in composition group of answer choices? Why do asteroids and comets differ in composition? Asteroids formed inside the frost line, while comets formed outside. When do comets generally begin to form a tail? Where are the Trojan asteroids located? Why do asteroids differ in composition? Why do asteroids and […]
What is the main difference between the movement of plants and animals?
What is the main difference between the movement of plants and animals? While both plants and animals are living organisms but they can be differentiated with the movement characteristics. Plants can’t move from one place to another while on the other hand animals can move from one place to another because animals contain specialized protein […]
Can Bone Bend?
Can Bone Bend? Long bones may bend without breaking the cortex. Children’s bones can be bent to 45 degrees before the cortex is disrupted and a greenstick or a complete fracture occurs. However if the bending force is released the bone may only partially return to its pre-bent position, resulting in plastic bowing. Does vinegar […]
