Answer:
Less than for both the answers
Step-by-step explanation:
If we multiply 3/5*2/3 that gives us 6/15 or 2/5 that is less than 2/3.
if we multiply 3/5*2/3 that gives us 6/15 or 2/5 that is less than 3/5.
The answer is 0.5 repeating
Answer:
>12 years
Step-by-step explanation:
P' = P (1 + r)ⁿ
P' = 2P
2P = P (1 + 0.06)ⁿ
1.06ⁿ = 2
n = log₁.₀₆ 2 = 11.9
The factors<span> of 155 are 1, 5, 31, and 155, thus </span>the prime factorization should be 5 and 31.
The reaction force exerted by the floor of the elevator on the man is D.944 N
Step-by-step explanation:
When the elevator is accelerating upwards at 2 m/s² there occurs a fictitious force acting downwards to produce a downward acceleration of 2 m/s².
The formula to apply here is ;
Weight due to gravity=mg where m is mass of the man and g is acceleration due to gravity.
Due to additional downward acceleration the total acceleration downwards will be : 9.8+2 = 11.8 m/s²
The man weighs down on the elevator floor with a force of ;
F=m(a+g) where m is mass of man, a is acceleration
F=80( 9.8+2)
F=80(11.8)= 944 N
The reaction force by the floor of the elevator is thus 944 N
