What is the importance of food chain and food web?
What is the importance of food chain and food web? Food web is an important conceptual tool for illustrating the feeding relationships among species within a community, revealing species interactions and community structure, and understanding the dynamics of energy transfer in an ecosystem. What is food chain and food web in ecosystem? Food chain is […]
Which of these lenses can be used to form virtual images of the object?
Which of these lenses can be used to form virtual images of the object? (i) Concave lens is used to get a virtual and diminished image of an object. Which lens produces a real image? Convex (converging) lenses can form either real or virtual images (cases 1 and 2, respectively), whereas concave (diverging) lenses can […]
Is tensor a metric?
Is tensor a metric? The metric tensor is an example of a tensor field. Thus a metric tensor is a covariant symmetric tensor. From the coordinate-independent point of view, a metric tensor field is defined to be a nondegenerate symmetric bilinear form on each tangent space that varies smoothly from point to point. Is tensor […]

What is natural sources of heat?
What is natural sources of heat? Light is produced by the sun. The sun is the main source of heat, warmth, and light for organisms living on Earth. Without the sun’s energy, Earth would be completely dark and freezing cold. Living organisms use heat and light from the sun. What sources of heat are there […]
What comes to your mind when you hear the word mutation?
What comes to your mind when you hear the word mutation? When we hear the word mutation, it conjures to mind hideous images of human-fish hybrids that might come swimming away from Chernobyl, animals with two heads and Caesar from Planet of The Apes. Mutations are the mechanism behind evolution, and the reason behind cancer […]
Is Lambda slower than EC2?
Is Lambda slower than EC2? Lambda container can be spun up based on each request. However, it will involve cold start time, which is not significant compared to the EC2 instance setup time. So, for this use case, Lambda will have more latency per request than EC2 but significantly less than the EC2’s first request. […]
How heat moves from one solid to another solid?
How heat moves from one solid to another solid? Conduction transfers heat energy in solids. The moving particles of a warm soild material can increase the heat energy of the particles in a cooler solid material by transferring it directly from one particle to the next. Since particles are closer together, solids conduct heat better […]
How does the force of gravity change if the distance between two objects triples?
How does the force of gravity change if the distance between two objects triples? If the mass of one of the objects is tripled, then the force of gravity between them is tripled. If the separation distance between any two objects is tripled (increased by a factor of 3), then the force of gravitational attraction […]
