Answer & ExplanationAnswer: A) The most commonly thought of hazard in construction. This hazard includes radiation, extreme temperatures, noise, and vibration.
Explanation:
A physical hazard is defined as "A factor within the environment that can harm the body without necessarily touching it."
Vibration and noise are examples of physical hazards.
Physical hazards include but aren't limited to electricity, radiation, pressure, noise, heights and vibration amongst many others.
If in the following set of numbers, the first and the third digits are interchanged in each number, which number will be second from the end if arranged in ascending order after interchanging the digits ?
Given numbers are 585 546 514 404 206 369 Then interchanging the 1st and 3rd digits of the given numbers, we get 585 645 415 404 602 963 Now, arranging them in ascending order 963 645 602 585 415 404 Then the last second number is 415.
Facilitate means assist someone in their progress or work. Here Help is the only word which is similar in meaning with facilitate. Halt and check are antonyms i.e opposite in meaning of facilitate.
If the positions of the first and the fifth digits of the number 14278359 are interchanged, similarly the positions of the second and the sixth digits are interchanged and so on, then which of the following will be the second digit from the right end after the rearrangement ?
Given number is 14278359 As given 1st and 5th digits, 2nd & 6th, 3rd & 7th and 4th & 8th digits are to to be interchanged. Therfore, the rearranged number is 83591427 Then, the second digit from the right end is 2.
'K' cycled from A to B at 10 kmph and returned at the rate of 9 kmph. 'L' cycled both ways at 12 kmph. In the whole journey 'L' took 10 minutes less than 'K'. Find the distance between A and B ?
Let 'd' be the distance between A and B K -time = d/10 + d/9 = 19d/90 hours L -time = 2d/12 = d/6 hours We know that, 10 min = 1/6 hours Thus, time difference between K and L is given as 10 minutes. => 19d/90 - d/6 = 1/6 => (19d-15d)/90 = 1/6 => 4d/90 = 1/6 Thus, d= 15/4 km = 3.75 km.
