<h3>Answer</h3>
Tools that magnify objects Tools that don't magnify objects
magnifying glass rule
telescope binoculars
microscope
<h3>Explanation</h3>
radio dish: is use to receive radio waves from the air.
binoculars: provide a magnified stereoscopic view of distant objects.
streak plate: is a technique which is used to grow bacteria on a growth media surface so that individual bacterial colonies are isolated and sampled.
wind vane: is used to determine wind direction.
ruler: is used for measuring a line.
microscope: is used to magnify the objects which are not visible by naked eyes.
magnifying glass: is used to magnifying tiny objects which are difficult to see yet they are visible.
telescope: use by space scientist to examine astronomical event that may take place in the sky which is too far.
Answer:
<em>Muons reach the earth in great amount due to the relativistic time dilation from an earthly frame of reference.</em>
Explanation:
Muons travel at exceedingly high speed; close to the speed of light. At this speed, relativistic effect starts to take effect. The effect of this is that, when viewed from an earthly reference frame, their short half life of about two-millionth of a second is dilated. The dilated time, due to relativistic effects on time for travelling at speed close to the speed of light, gives the muons an extended relative travel time before their complete decay. So <em>in reality, the muon do not have enough half-life to survive the distance from their point of production high up in the atmosphere to sea level, but relativistic effect due to their near-light speed, dilates their half-life; enough for them to be found in sufficient amount at sea level. </em>
The answer is b) false. Stars are mainly classified by their spectra (the elements they absorb) and their temperature.
Focusing means you’re paying particular attention to something
