Answer:
Explanation:
Energy of gamma rays due to ore decay is
Energy of gamma ray produced in seconds is
Activity
Total energy of gamma ray produced in second is
E-energy of gamma ray produced in an hour is
Gamma ray energy absorbed by meat = 30% (in 1 hour) of E is 0.3E
Dose required to kill pathogen = 4000Gy=4000J/kg
The kilogram of meat that can be produced per hour is
The meat that can be produced =
Answer:
avg speed =total distance/total time
total distance =2km (given)
total time=1/10 +1/25=7/50
so avg speed =100/7=14.28
Answer:
A). 11462 Joules
B). 32345.25 Joules
Explanation: The workdone by a variable force undergoing a displacement is in d line of integral.
Find the attached file for the solution.
Answer:
P₃ > P₁ > P₂
Explanation:
To rank pressure of the given situation
a) we know
Pressure at height h below
P = ρ g h
density of salt water, ρ = 1029 kg/m³
P₁ = 1029 x 10 x 0.2
P₁ = 2058 Pa
b) density of fresh water, ρ = 1000 kg/m³
P₂ = 1000 x 10 x 0.2
P₂ = 2000 Pa
c) density of mercury, ρ = 13593 kg/m³
P₃ = 13593 x 10 x 0.05
P₃ = 6796.5 Pa
Rank of Pressures from highest to lowest
P₃ > P₁ > P₂
