Why is iron so important? Iron is a mineral that the body needs for growth and development. Your body uses iron to make hemoglobin, a protein in red blood cells that carries oxygen from the lungs to all parts of the body, and myoglobin, a protein that provides oxygen to muscles. Your body also needs […]

At what pressure does diesel ignite? 234 psi Can you light a fire with diesel? Diesel requires a much hotter flame than say gasoline to ignite, however it will ignite. Diesel fuel has a flash point between 52 and 96 degrees C. So, yes, diesel fuel can catch fire and therefore, under the right conditions, […]

What is the importance of force? Forces are very important in all aspects of daily life: The force of up-thrust helps to keep objects floating. It is the example of action at a distance force. Gravity pulls us back down to earth (without touching us) when we jump up in the air. Is the force […]

Do you drown slower in salt water? There is also a discrepancy between the time it takes to drown in the different liquids as well.

What is the kinetic energy formula? Kinetic energy formula KE = 0.5 * m * v² , where: m – mass, v – velocity. How do you find kinetic energy? In classical mechanics, kinetic energy (KE) is equal to half of an object’s mass (1/2*m) multiplied by the velocity squared. For example, if a an […]

What is heterozygous a blood type? ABO Blood Types The A and B alleles are dominant to the O allele. When both inherited alleles are O, the genotype is homozygous recessive and the blood type is O. When one of the inherited alleles is A and the other is B, the genotype is heterozygous and […]

What are the 7 troubleshooting steps? The steps are: identify the problem, establish a theory of probable cause, test the theory, establish a plan (including any effects of the plan), implement the plan, verify full system functionality, and—as a final step—document everything. What are the common computer problems and solutions? Top 10 common computer problems […]

What household item can be used as a magnet? Paper clips, scissors, screws, nuts, and bolts are just a few common everyday objects that are magnetic.
