Answer:
24°
Explanation:
sin(34°)/sin(x)=v2/v1
x=arcsin(2,1*sin(34°)/2,8)=24°
Is there any answers choices..?
Answer:
I think its the Blue wave, im not sure so dont take my word for it.
Explanation:
Answers:
a) 154.08 m/s=554.68 km/h
b) 108 m/s=388.8 km/h
Explanation:
<u>The complete question is written below:

<u></u>
<em>In 1977 off the coast of Australia, the fastest speed by a vessel on the water was achieved. If this vessel were to undergo an average acceleration of
, it would go from rest to its top speed in 85.6 s. </em>
<em>a) What was the speed of the vessel?
</em>
<em>
</em>
<em>b) If the vessel in the sample problem accelerates for 1.00 min, what will its speed be after that minute? </em>
<em></em>
<em>Calculate the answers in both meters per second and kilometers per hour</em>
<em></em>
a) The average acceleration
is expressed as:
(1)
Where:
is the variation of velocity in a given time
, which is the difference between the final velocity
and the initial velocity
(because it starts from rest).

Isolating
from (1):
(2)
(3)
(4)
If
and
then:
(4)
b) Now we need to find the final velocity when
:

Answer:
The magnitude will be "
". The further explanation is given below.
Explanation:
Trying to determine what is usual for a rectangular loop plane,
⇒ 
Magnetic moment is given as:
μ = 
On putting the values in the above formula, we get
μ = ![(5.5A)[(0.3m)(0.4m)][(Cos35^{\circ})(\hat{i})+(Sin35^{\circ})(-\hat{k})]](https://tex.z-dn.net/?f=%285.5A%29%5B%280.3m%29%280.4m%29%5D%5B%28Cos35%5E%7B%5Ccirc%7D%29%28%5Chat%7Bi%7D%29%2B%28Sin35%5E%7B%5Ccirc%7D%29%28-%5Chat%7Bk%7D%29%5D)
= ![0.66 Am^2[(Cos35^{\circ})(\hat{i})+(Sin35^{\circ})(\hat{k})]](https://tex.z-dn.net/?f=0.66%20Am%5E2%5B%28Cos35%5E%7B%5Ccirc%7D%29%28%5Chat%7Bi%7D%29%2B%28Sin35%5E%7B%5Ccirc%7D%29%28%5Chat%7Bk%7D%29%5D)
Now the external vector-shaped torque seems to be:
Magnitude,

On putting the values in the above formula, we get
⇒ ![\sigma=[(0.06Am^2)(Cos35^{\circ}(-\hat{i})+Sin35^{\circ}(-\hat{k})]\times (2.9T)(-\hat{i})](https://tex.z-dn.net/?f=%5Csigma%3D%5B%280.06Am%5E2%29%28Cos35%5E%7B%5Ccirc%7D%28-%5Chat%7Bi%7D%29%2BSin35%5E%7B%5Ccirc%7D%28-%5Chat%7Bk%7D%29%5D%5Ctimes%20%282.9T%29%28-%5Chat%7Bi%7D%29)
