What is the largest type of tephra? All explosive volcanic eruptions generate tephra, fragments of rock that are produced when magma or or rock is explosively ejected. The largest fragments, blocks and bombs (>64 mm, 2.5 inches diameter), can be expelled with great force but are deposited near the eruptive vent. How do you protect […]
What is the melting point of acetic acid?
What makes the ball keeps on rolling?
What makes the ball keeps on rolling? When a rigid ball rolls on a plane with no other forces, it is known that no friction applies and the ball keeps rolling. Static friction applies in the opposite direction of the tangential part of the external force, with equal magnitude. What do you call the force […]

How do you kill Bacillus anthracis endospores?
How do you kill Bacillus anthracis endospores? anthracis are killed by UV radiation, dry heat, wet heat and desiccation. Methods and results: Hydrated B. anthracis spores were HTGE treated at c. 220°C for 50 ms, and the treated spores were tested for germination, mutagenesis, rupture and loss of dipicolinic acid. Why does Bacillus anthracis form […]
Can we see wavelengths?
Can we see wavelengths? More simply, this range of wavelengths is called visible light. Typically, the human eye can detect wavelengths from 380 to 700 nanometers. Does white light exist?

Which is the correct expression for Half-Life?
Which is the correct expression for Half-Life? The time required for half of the original population of radioactive atoms to decay is called the half-life. The relationship between the half-life, T1/2, and the decay constant is given by T1/2 = 0.693/λ. What is the half-life for uranium 238? about 4.5 billion years How dangerous is […]
How does a ionic bond form?
How does a ionic bond form? An ionic bond is formed by the complete transfer of some electrons from one atom to another. The atom losing one or more electrons becomes a cation—a positively charged ion. The atom gaining one or more electron becomes an anion—a negatively charged ion. What must occur for an ionic […]
