Answer:The object characteristics
Explanation:the objects characteristics
Perception is the sensory experience of the world. It involves both recognizing environmental stimuli and actions in response to these stimuli. Through the perceptual process, we gain information about the properties and elements of the environment that are critical to our survival.
Answer:
Explanation:
moment of inertia of man
= mr² , m is mass of man and r is radius of table .
= 53 x 2.9²
=445.73
angular momentum of runner = mvr , v is velocity of runner .
53 x 3.6 x 2.9 = 553.32
angular momentum of turntable
= Iω , I is moment of inertia and ω is angular velocity of table .
= 76 x .2 = 15.2
Total angular momentum = 553.32 - 15.2
= 538.12
Let the common velocity when the runner comes to rest with respect to turntable be ω.
total moment of inertia of the system
= 445.73 + 76
= 521.73
Applying law of conservation of angular momentum
total initial angular momentum = final angular momentum
538.12 = 521.73 ω
ω = 1.03 rad /s .
I know that ultrasounds are used to determine the sex of the fetus and its general health. I’m not sure about infrasounds.
Answer:
A
Explanation:
The greatest concentration of atomic mass is in the nucleus because it is made up of protons and neutrons. The electrons surrounding the nucleus don't have as much mass as protons or neutrons.
Hopefully this helps...
