Answer:
(a) 18.87 V
(b) 23.81 V
(c) 20.75%
Explanation:
The answers are given in the pictures. I have attached the pictures because circuits were needed to be drawn which are easier to understand when done on page. The page are numbered on top left corner.
Answer:
So the answer is yes, we can the back be shaped like a spinning rod
spinal column that is approximated by a long and narrow rod,
Explanation:
The bone system of the body is very well modeled in physics, the back has a spinal column that is approximated by a long and narrow rod, this rod is fixed in the lower part to the coccyx and has a weight in the upper part (head), this rod has longitudinal vertical movement and twisting movement around the lower part of the bar.
So the answer is yes, we can the back be shaped like a spinning rod
Answer:
0.87 m
70.6 Hz
Explanation:
= length of the rope = 1.30 m
= order of the harmonic = 3
= Wavelength
Wavelength is given as
= 0.87 m
= Speed of transverse wave = 61.4 m/s
= frequency of the third harmonic
frequency is given as
= 70.6 Hz
The choices can be found elsewhere and as follows:
A)There will not be a change.
<span>B)The voltage will decrease by a factor of two. </span>
<span>C)The voltage will increase by a factor of two. </span>
<span>D)The two coils of wire will cancel out the magnetic field. </span>
<span>E)The voltage will be zero.
</span>
I believe the answer is option C. If the magnet is put inside two coils of wire, then the voltage will increase by a factor of two. Hope this answers the question.
To solve this problem, we can use the cosine formula for
calculating the length of the displacement:
c^2 = a^2 + b^2 – 2 a b cos θ
where c is the displacement, a = 3.5 km, b = 4.5 km, and θ
is the angle inside the triangle
Since the geeze turned 40° from west to north, so the
angle inside the triangle must be:
θ = 180 – 40 = 140°
c^2 = 3.5^2 + 4.5^2 – 2 (3.5) (4.5) cos 140
c^2 = 56.63
c = 7.53 km
<span>So the magnitude of the displacement is 7.53 km</span>
