Which stars are the youngest? If proven, the newly discovered neutron star will be the youngest one known by humanity, beating the current youngest supernova remnant is Cassiopeia A, which is 330 years old that can be found 11,000 light-years away from Earth and can be found within our galaxy. Why doesn’t the helium core […]
How is wind speed indicated what is the unit used to define wind speed?
How is wind speed indicated what is the unit used to define wind speed? How is Wind Speed and Direction measured? Wind speed is typically reported in miles per hour, knots, or meters per second. One mile per hour is equal to 0.45 meters per second, and 0.87 knots. Wind direction is typically reported in […]

How do the founder effect and bottlenecking differ?
How do the founder effect and bottlenecking differ? Bottlenecks and founder effects. Genetic drift can cause big losses of genetic variation for small populations. Population bottlenecks occur when a population’s size is reduced for at least one generation. A founder effect occurs when a new colony is started by a few members of the original […]

How accurate are dial calipers?
How accurate are dial calipers? Quality dial, Vernier or digital calipers can all return an accuracy of about 0.001 inch over 6 inches if correctly used, although the accuracy is likely to diminish over longer spans. What are the 3 ways a dial caliper can be used to measure? There are 4 measurements you can […]
How does the angle of deviation depends on the refracting angle of the prism?
How does the angle of deviation depends on the refracting angle of the prism? The angle of deviation (δ) increases with the increase in the angle of prism (A). What is the angle of deviation when angle of incidence is 60? Answer. The angle of deviation will be 60° only. As refracted ray goes strainght […]
What are the examples of reflection?
What are the examples of reflection? Common examples include the reflection of light, sound and water waves. The law of reflection says that for specular reflection the angle at which the wave is incident on the surface equals the angle at which it is reflected. Mirrors exhibit specular reflection. What’s an example of a reflection […]
What happens if 2 spiral galaxies collide?
What happens if 2 spiral galaxies collide? For example, two spiral galaxies can merge and form an elliptical galaxy. Galaxies are also composed of gas and dust. The gravitational pull of both colliding stars can interact with this materials, creating friction and shock waves that can ignite the formation of new stars. What will happen […]
How long do telescope mirrors last?
How long do telescope mirrors last? about three to five years Do microscopes use mirrors? The light microscope and telescope use convex lenses and mirrors to make enlarged images of very tiny or distant objects. A camera uses a convex lens to make a reduced image of an object. Why is a mirror used in […]
