What force twists a material by turning the ends in opposite directions? Torsion forces twist a material by turning the ends in opposite directions. What is internal and external force? • Internal Forces: Forces which act on one part of an object. by another part of the same object. • External Forces: Forces which act […]

Why is density calculated from slope more accurate? Briefly explain why it is more accurate to use the slope of the plot to determine the density than it is to use the data from a single determination. when using the slope you are given more of an average, which will give you a more accurate […]

Which motor can rotate in both directions? DC motors How can the direction of DC motor be changed? We can change the direction of DC motor 1) by changing the polarity of applied field voltage. 2) by changing the polarity of the applied voltage to the armature winding. 3) if we change both of the […]

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 […]

Do forces cause some change in motion? Force is defined as a push or pull on an object. Forces affect how objects move. They may cause motion; they may also slow, stop, or change the direction of motion of an object that is already moving. Since force cause changes in the speed or direction of […]

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 […]

Is there undersea landslide? Underwater landslides are common features on steep continental margins. Underwater (also called submarine) landslides rapidly shape the seafloor environment by transferring large quantities of sediment and rock downslope from the continental shelf into the deep ocean. Has Texas ever had a tsunami? Today, 3 News sat down with a geologist at […]

What is risk allele frequency? risk allele: in the context of a disease, this is the allele that confers a risk of developing the disease. Most of the time, risk allele = minor allele, as most people will not carry the risk allele. How do you find the frequency of a dominant and recessive allele? […]

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, […]
