Answer:
1.241 kg
Explanation:
The mass of the man in kg is 195 pound * (1/2.2) kg/pound = 195/2.2 = 88.64 kg
If 1.4% of the mass of a human body is calcium, then the mass of calcium inside the 88.64 kg man is
1.4% * 88.64 = 88.64*1.4/100 = 1.241 kg
So there's 1.241 kg of calcium inside a 195-pound man
Answer:
Explanation:
Resolving the parallel resistor branches
The equivalent resistor is now in series with the 2.0 Ohm resistor
so, by using Ohm's Law
Answer:
warmer air
Explanation:
the particles are more excited which increases the probability that the particles will bump into each other
For the answer to the question, ergonomics<span> is the science of fitting the job to the worker. When there is a mismatch between the physical requirements of the job and the physical capacity of the worker, work-related musculoskeletal disorders (MSDs) can result. Ergonomics is the practice of designing equipment and work tasks to conform to the capability of the worker, it provides a means for adjusting the work environment and work practices to prevent injuries before they occur.</span>
Answer:
Average force = 67 mn
Explanation:
Given:
Initial velocity u = 0 m/s
Final velocity v = 67 m/s
Time t = 1 ms = 0.001 sec.
Computation:
Using Momentum theory
Change in momentum = F × Δt
(v-u)/t = F × Δt
F × 0.001 = (67 - 0)/0.001
F= 67,000,000
Average force = 67 mn
