Answer:
it might be damaged
Explanation:
depending on how harsh the weather is it might be more or less damaged
Answer: The workers may come only as far as 0.24m
<em>(Note: The queston is incomplete. Here is the complete question below)</em>
A shielded gamma ray source yields a dose rate of 0.048rad/h at a distance of 1.0m for an average-sized person. If workers are allowed a maximum dose of 5.0 rem in 1 year, how close to the source may they operate, assuming a 35-h work week? Assume that the intensity of radiation falls off as the square of the distance. (It actually falls off more rapidly than 1/r2 because of absorption in the air, so your answer will give a better-than-permissible value.)
Explanation:
Note: 1rem = 1rad
Dose rate per hour from a distance of 1.0m = 0.048rem/h
maximum daily dose in a year for a 35-h week = 5rem/yr / (35h*52*1yr) = 0.0027rem/h.
The required distance is obtained from the <em>inverse square law </em>for radiation<em> which states that the intensity of the radiation </em><em>(I)</em><em> decreases in proportion to the inverse of the distance from the source </em><em>(d)</em><em> squared.</em>
From the law, I₁/I₂ = d₁²/d₂²
Therefore, by knowing the intensity at one distance, one can find the intensity at any other distance.
From the given values I₁ = 0.048rem/h, I₂ = 0.0027rem/h, d₁ = 1.0m, d₂ = ?
d₂² = I₂d₁²/ I₁
d₂² = 0.0027rem/h * (1.0)²/ 0.048rem/h
d₂² = 0.05625m²
d₂ = √(0.05625)
d₂ = 0.24m
Answer:
<em>When the depth is less than 0.5 m</em>
Explanation:
Waves will begin to touch bottom when depth of the water is less than 1/20 of the wavelength. This type of wave is known as a shallow wave.
wavelength = 10 m
It will begin to touch bottom when its depth is less than
1/20 x 10 = <em>0.5 m</em>
Answer:
Collision can be classified as either elastic or inelastic. The main difference between elastic and inelastic collisions is that, in elastic collisions, the total kinetic energy of the colliding objects before the collision is equal to the their total kinetic energy after the collision. In inelastic collisions, the total kinetic energy of the objects after the collision is less than the total kinetic energy of the objects before the collision.
