Antivirus software is a software which is used to prevent scan detect and delete viruses from a computer.
Let D be the total distance (say in meters) traveled by the train and T the time (say in seconds) it takes to do so. (Assume the train moves in a straight line in only one direction.) Then the average velocity of the train as it covers this distance is
v (ave) = D/T
We're told the train can traverse a distance of D/4 in a matter of T/2 seconds if it moves at a speed of 5 m/s. This means
D/4 = (5 m/s) (T/2)
⇒ 5 m/s = 1/2 D/T
⇒ v (ave) = D/T = 10 m/s
Answer:
67 m/s
Explanation:
by 1st equation of motion:-
v= u+ at
= 25 + 7×6
= 25+ 42
= 67 m/s
Aside from Earth-quakes and volcanoes, a scientist noticed how all of the continents fit almost PERFECTLY together. And he used that as evidence to prove the theory of continental drift.
I hope this helps! :)
Answer:
Galileo Galilei
Explanation:
although Galileo was not the scientist who invented the telescope, he was the first to use it to observe celestial objects. he used the telescope in 1609. his discovery included more accurate information about the moon, the sun and some of the planets.
