Answer:
The average speed of the bus, v = 1.55 m/s
Explanation:
Given that,
Number of blocks traveled by bus towards east = 6
Number of blocks traveled by bus towards north = 8
Length of each block = 100 m
Distance traveled by bus towards east 6 x 100 = 600 m
Distance traveled by bus towards north 8 x 100 = 800 m
The total distance traveled, d = 600 + 800 = 1400
Time taken by the bus to travel is, t = 15 minutes
The velocity is given by the formula
v = d/t m
Substituting the values in the above equation
v = 1400 m /(15 x 60) s
= 1.55 m/s
Hence, the average speed of the bus, v = 1.55 m/s
Answer:
Technique to reduce Noise, magnetic attraction and Twitching sensation
Explanation:
Changing magnetic fields cause loud knocking noise this can be overcome by ear protection.
Strong and Static magnetic fields attract magnetic objects that can be avoided by screening of people and objects before entering in that area.
Twitching Sensation due to nerve stimulation can be avoided by reducing the exposure to magnetic field.
