Answer:
Ionizing radiation is radiation, traveling as a particle or electromagnetic wave, that carries sufficient energy to detach electrons from atoms or molecules, thereby ionizing them. When the dose is high enough, ionizing radiation causes two types of harm to humans: direct tissue damage and cancer. Direct tissue damage happens when enough molecules are broken apart that the cells simply can no longer function. This can lead to radiation burns, radiation sickness, organ failure, etc.
Hope this helps!!
Have a nice evening :)
Explanation:
On a Fahrenheit thermometer, the gas becomes 18 degrees warmer.
Answer:
a) the final velocity is 35.75 ft/s
b) The final elevation is 45 ft
Explanation:
Given the data in the question;
Weight of object; W = 100 lbf
Change in kinetic energy; ΔE = 500 ft-lb
so
m - m = ΔE
m - m = 500
multiply both sides by 2
m - m = 1000
m( - ) = 1000
- = 1000/m
- = (1000)(g) / W
we know that, acceleration due to gravity g = 9.8 m/s² = 32.18 ft/s²
so we substitute
- = (1000)(32.18) / 100
- = (1000)(32.18) / 100
- = 32180 / 100
- = 321.8
since The initial velocity is given to be 40 ft/s;
(40)² - = 321.8
1600 - = 321.8
= 1600 - 321.8
= 1278.2
= √1278.2
= 35.75 ft/s
Therefore, the final velocity is 35.75 ft/s
b)
we know that;
change in potential energy is;
ΔP.E = mg( h - h )
given that; increase in potential energy; ΔP.E = 1500 ft-lbf
and mg = Weight = 100 lbf
we substitute
1500 = 100( h - h )
h - h = 1500 / 100
h - h = 15 ft
given that, elevation of the object; h = 30 ft
h - 30 ft = 15 ft
h = 15 ft + 30 ft
h = 45 ft
Therefore, The final elevation is 45 ft

Answer:
Coefficient
Explanation:
For an object on level ground, the ratio of the friction force to the weight is the coefficient of friction.
F / W = μ
