Answer:
Orbital Time Period is 24 years
Explanation:
This can be explained by the definition of time period.
Time period can be defined as the time taken by an object to complete one cycle, here, time taken to complete one revolution.
Also, we know that an extra solar planet which is also called as an exo planet is that planet which is outside our solar system and orbits any star other than our sun. The system in consideration is extra solar system with a single planet.
Therefore, the time taken by the parent star to move about its mass center is the orbital time period that is 24 years.
Susie's vertical displacement is 2.1 m
Explanation:
In order to solve this problem, we have to resolve the displacement vector along the vertical direction.
The vertical component of a vector is given by:
where
v is the magnitude of the vector
is the angle between the direction of the vector and the horizontal
Therefore, the vertical component of the displacement in this problem is given by
where
d = 3 m is the magnitude of the displacement
is the angle between the displacement and the horizontal
Substituting, we find

Answer:
The neutral wire and the ground wire.
Explanation:
The black wire is the hot wire
The neutral wire provides the return path for the current provided by the hot wire.
The ground wire is connected to any metal parts in an appliance for example microwave.
A standard electrical outlet has three wires connected to it: the hot, the neutral, and the ground. There is no potential difference between the neutral wire and the ground wire.
Answer:
it's 10 you can see it goes by 2 and the others fo by 1 pretty simple
Answer:
6.65×10⁻⁷ s
Explanation:
Speed of light in water = Total distance traveled in water/time
c = d/t ....................... Equation 1
Where c = speed of the light pulse in water, d = distance traveled in water, t = time.
also
c = v/n ..................... Equation 2
Where v = speed of light in air, n = refractive index of water
Substituting equation 2 into equation 1
v/n = d/t
making t the subject of the equation,
t = nd/v.................. Equation 3
Given: 150 m.
Constant: n = 1.33, v = 3.0×10⁸ m/s
Substitute into equation 3
t = 1.33(150)/3.0×10⁸
t = 6.65×10⁻⁷ seconds.
Hence the time = 6.65×10⁻⁷ s
