Total distance covered is 47.1 m whereas displacement is zero.
<h3>Calculation:</h3>
Given,
Diameter, d = 5 m
No. of revolutions = 3
Radius, r = 5/2 = 2.5 m
To find,
Distance =?
Displacement =?
Distance covered in one revolution = 2πr
Put the values in this,
Distance = 2 × 3.14 × 2.5
= 15.7 m
Total distance covered in 3 revolution = 3 × 31.4
= 47.1 m
Displacement is the change in the position of the object or the distance between the initial and final position.
After 3 revolutions the particle comes back to its initial position. Therefore, the displacement is zero.
Hence, the total distance covered in 3 resolutions is 47.1 m whereas displacement is zero.

<u>Answer:</u>
The gauge pressure is 6670.8 Pascal
<u>Explanation:</u>
Given the height is 0.68 m
The Gauge pressure is determine by the formula,
Gauge pressure , P = hdg
Where h = 0.68 m
d = 1000
g = 9.81
Substituting the values in the formula of Gauge pressure, we get
Gauge Pressure = hdg =
Gauge Pressure = 6670.8
Therefore, the gauge pressure is 6670.8 Pascal
<span>When sound waves travel from air into water, they'll immediately
start moving faster. (Their speed will increase.)
Of course, this means that although their frequency won't change,
their wavelength will increase.</span>
Answer:
I = 4.11 10⁻¹² A
Explanation:
For this exercise we can use Ampère's law, which relates the magnetic flux to the current inside the surface and the magnetic permeability
∫ B. ds = μ₀ I
Let's write a surface that is a circle around the neuron, in this case the direction of the field and the displacement vector are parallel, which reduces the scalar product to an ordinary product
∫B ds = μ₀ I
The field is constant so we take it from the integral that is immediate
B ∫ ds = μ₀ I
B 2π r = μ₀ I
I = B 2π r / μ₀
I = 1.28 10⁻¹⁵ 2π 0.0642 / 4π 10⁻⁷
I = 4.11 10⁻¹² A
I would say B.) the blonde hair was a result of the expression of a recessive gene. - the dominate gene is brown hair and the recessive gene is blonde hair...hope this helps
