Answer:
Furniture mover.
Explanation:
A strain is a soft tissue injury that happens on the muscle or tendon - it could occur on several parts of the body, such as hands or legs. When it is acute, an incident might have caused it and proper rest would let it heal.
This type of injury could happen to athletes, but those who are at risk are those who are involved in sports field such as wrestling and football. Thus, baseball players are a lower risk.
Bank tellers and heart surgeons would not suffer from this type of injury - they are more likely to suffer from chronic than acute strains do to the overuse of certain muscles.
The group that is at the highest risk are people who move heavy objects - such as furniture mover.
Velocity of the sled is 3.2 m/s
Answer:
R = 9.92 m
Explanation:
For this exercise let's use the Stefa radiation equation
P = σ A e T⁴
Where the Stefan-Boltzmann constant is worth 5,670 10⁻⁸ W/m²K⁴, A is the area of the body and the emissivity and T is the absolute temperature
Let's calculate irradiated
P = 5,670 10⁻⁸ 1.6 0.97 (273 +30) 4
P = 7.417 10² W
The emitted power is distributed on a spherical surface as it progresses, whereby the intensity detected by the python I = 0.6 W / m2
P = I A
The area of the sphere is
A = 4π R²
P = I 4π R²
R² = P / 4π I
R = √ [7.417 102 / (4π 0.6)]
R = √ 98.37
R = 9.92 m
