Answer:
false?
Explanation:
The higher the modulus, the more stress is needed to create the same amount of strain; an idealized rigid body would have an infinite Young's modulus.
You could use clay, sticks, rocks, Legos,
Answer:
The electromagnetic spectrum in order of increasing frequency is - radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays.
The frequency of the gamma rays is >3×10
19
m.
Hence, the gamma rays has the maximum frequency in the electromagnetic spectrum.
Answer:
20% of the human body float above the surface in the dead sea.
Explanation:
Given data,
The human density after inhaling, d₁ = 945 kg/m³
The human density after exhaling, d₂ = 1020 kg/m³
Therefore the average human density, d = 982.5 kg/m³
The density of the dead sea, D = 1230 kg/m³
The percentage of density of human body to the dead sea is,
P % = (982.5 / 1230) x 100 %
= 80 %
Therefore, the human body has 80% of dead sea density.
Hence, 20% of the human body float above the surface in the dead sea.
