Answer:
No
Explanation:
Without bones, we would have no structural frame for our skeleton, we would be unable to move our skeleton, which would leave our internal organs poorly protected, cause lack blood and be short on calcium.
Hope this helps!
It communicates messages in many different ways, soothes the mind and also helps relieve stress from our everyday lives. It is a sound that is in a controlled and tuned type of matter, relying on frequency and pitch of the voice. Not only is basic sound important, but I believe music is crucial to human life as well.
Answer:
Explanation:
We know that the formula for resistance in terms of length and area is given by
R = p l/ a
Where p be the resistivity and a be the area of crossection
a = pi × d^2 / 4
Where d be the diameter
a = 3.14 × (1.628 × 10^-3)^2 / 4
a = 2 × 10^-6 m^2
R = 1.68 × 10^-8 × 24 / (2 × 10^-6)
R = 20.16 × 10^-2 ohm
By use of Ohm's law
V = IR
V = 13 × 20.16 × 10^-2
V = 2.62 Volt
Answer:
Explanation:
a ) Let angle of incidence and angle of refraction be i and r respectively .
submarine is 300 m away from the shore . The point where laser strikes the surface of sea is 90 m horizontally away .
Tan r = 90 / 120
= 3 / 4
.75
r = 37 degree
c ) sini / sin37 = 1.333
sini = .8
i = 53 degree
Tan 53 = 210 / h , h is height of the building .
h = 210 / tan 53
= 158 m
Answer:
Explanation:
The intensity of a sound wave is given by
where
P is the power of the wave at the source
A is the area over which the sound wave propagates
In this problem, we have
P = 70.0 W is the power
We want to know the intensity at a distance of r = 25.0 m from the orchestra, so since the sound waves propagates radially, we must consider a spherical surface of radius r, so the area is
Therefore, the intensity of the wave is
