What is the difference between speed and power in PE? Power is the ability to exert as much force as possible in the shortest amount of time. To put it simply, speed + strength = power. When it comes to power, you won’t be able to lift as much weight as you would if you […]
What is the importance of formulating a hypothesis?
What is the importance of formulating a hypothesis? A hypothesis enables researchers not only to discover a relationship between variables, but also to predict a relationship based on theoretical guidelines and/or empirical evidence. Developing a hypothesis requires a comprehensive understanding of the research topic and an exhaustive review of previous literature. What is a broader […]
What is the net force of a rock falling at constant terminal velocity?
What is the net force of a rock falling at constant terminal velocity? Objects falling through a fluid eventually reach terminal velocity . At terminal velocity, the object moves at a steady speed in a constant direction because the resultant force acting on it is zero. Why does a parachutist does not fall with constant […]
What happens when switch is closed in RC circuit?
What primary advantage if any does a ball bearing have over a roller bearing?
What primary advantage if any does a ball bearing have over a roller bearing? As a general rule, ball bearings are used at higher speeds and lighter loads than are roller bearings. Roller bearings perform better under shock and impact loading. What are similarities and differences between a plain bearing and a roller bearing? Rollers […]
What are two most abundant elements in magma?
What are two most abundant elements in magma? Being that oxygen and silicon are the most abundant elements in magma, geologists define magma types in terms of their silica content, expressed as SiO2. These differences in chemical composition are directly related to differences in gas content, temperature, and viscosity. What is magma very short answer? […]
Why do we see sun before sunrise?
Why do we see sun before sunrise? The rising sun is visible to us before actual sun rise and after actual sunset because of the atmospheric refraction of light. The rays from the sun coming through space enter from rarer to the denser medium and hence bend slightly towards normal at each refraction and become […]
What are the similarities between mitochondria and chloroplast?
What are the similarities between mitochondria and chloroplast? Both the chloroplast and the mitochondrion are organelles found in the cells of plants, but only mitochondria are found in animal cells. The function of chloroplasts and mitochondria is to generate energy for the cells in which they live. The structure of both organelle types includes an […]
What are mixtures that Cannot be separated?
What are mixtures that Cannot be separated? An element is a pure substance that cannot be separated into simpler substances by chemical or physical means. There are about 117 elements. Which type of matter Cannot be broken down any smaller? a pure or elementary substance cannot be broken down into smaller or simpler constituents without […]
Is jellyfish a Benthos?
Is jellyfish a Benthos? Jellyfish are usually thought of as drifting organism there are in fact some forms of medusae and ctenophores that are benthic, with the adult sexual stage spending their entire life on the seafloor. Where would you most likely find benthos organisms? Explanation: Benthos organisms can be defined as the set organisms […]
