how long does it take the star and planet to complete one orbit around their center of mass?
Answer:
i think about 225-250 million years
Explanation:
Bottom line: The planets in our solar system orbit (revolve) around the sun, and the sun orbits (revolves) around the center of the Milky Way galaxy. We take about 225-250 million years to revolve once around the galaxy's center. This length of time is called a cosmic year.
what is the use if having a control condition in an investigation
Answer:
Thus, including a control condition allows researchers to compare the way things are in the presence of an independent variable with the way things would have been in the absence of an independent variable.

What does this poem mean:
A lake in the spring
Is a marvellous thing
Changes are on the way
The winter chills cease
with sunlight’s increase.
Cool waters cover the bay.
Water moves round
From surface to ground
Water is mixed this way
Spring storms bring rain
Lake water does gain
With nutrients caught in the fray
Tiny creatures abound
‘Cause algae’s around
The food chain is boosted this way.
the poem seems to be about the seasons transitioning from winter to spring. the poet explains the lake melting, the sunlight coming out, spring storms that add water to the lakes, and the creatures that come back to roam after winter comes to an end. im really sorry if that didnt help.

An Eider duck is flying Northeast at 25 m/s at an angle of 36.9 degrees to the ground (from the positive
X-axis). What are the horizontal and vertical velocities, respectively, of the duck's flight?
Answer:
Horizontal = 19.99212 m/s Vertical = 15.0151 m/s
Explanation:
Horizontal = Cos(36.9) x 25
Vertical = Sin(36.9) x 25

How far has a ball traveled after 3.6 seconds when thrown downward at a
velocity 3.75 m/s?
ball traveled 13.5 m/s after 3.6 seconds
Explanation:
u=3.75m/s, t=3.6s, g=9.8m/s².
Therefore, according to the formula,
S=ut+½gt².
S=(3.75×3.6)+½×9.8×(3.6)²
S= 13.5+63.504
S= 77.004m (approximately 77 m)
therefore the distance traveled by the ball is 77m.

Answer:
As a capacitor is charging it takes up charging current and there's significant drop of current as the voltage increases in the capacitor.
Thus, D is the correct option.
2nd qn,
A is the correct option. Since points B, C and D are points of interaction and the force can be experienced at intervals while at A the forces will be balanced.

A ball of mass 0.50 kg was thrown directly up at a speed of 6.0m/s.Calculate. A.its kinetic energy at 6ms^-1b.its maximum gain of potential energy. C.its maximum height gain.
ヘ（。□°）ヘヘ（。□°）ヘヘ（。□°）ヘヘ（。□°）ヘヘ（。□°）ヘ
A) Its kinetic energy be 9.0 Joule.
B) Its maximum gain of potential energy is 9.0 Joule.
C) Its maximum gain in height be 1.91 m.
What is speed?Speed is distance travelled by the object per unit time. Due to having no direction and only having magnitude, speed is a scalar quantity With SI unit meter/second.
Given parameters:
Mass of the ball: m = 0.50 kg.
Initial speed of the ball: v = 6.0 m/s.
A) its kinetic energy at initial = 1/2mv² = 1/2 × 0.50 × 6.0² Joule = 9.0 Joule.
B) As total energy is conserved., when the ball reaches its maximum height its initial kinetic energy fully transforms into potential energy. Its maximum gain of potential energy is its kinetic energy, that is, 9.0 Joule.
C) Its maximum gain in height be = √(v²/2g) = √(6.0²/2×9.8) m = 1.91 m.

what is needed to know in a physics exam?
Answer:
Review what you have done for that unit. Skim over it if you dont have enough time because it would greatly help. If you have mathamatics involved learn or make sure you are perfect at doing the equations you need to do. Just dont cheat because if you get caught you are going to get an imediete F which will be worse then getting half of them wrong. Good luck
Describe what happens when there is no Friction and you stop pushing on that object?
Describe what happens when there is Friction and you stop pushing on an object?
Are your answers to questions 1 and 2 the same? Why or why not? What causes that to be the same or different?
I give Brainliest!
Answer: see below
Explanation:
1) An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
Friction opposes relative motion. In its absence, a moving object will not stop.
2) If you stop pushing, the force of kinetic friction will produce an acceleration in the opposite direction of the velocity, and the object will slow down and stop.
3) No they are not the same, as one has friction and the other has no friction.

Explanation:
Electromagnetic Equipment
An electromagnet is a type of magnet with a magnetic field produced by an electric current. Electromagnets are often used in electrical devices that induce heat for cooking such as an oven (OPTION A).
Capacitor
As the voltage increases, the current decreases (OPTION D).
As the capacitor charges up, the potential difference across its plates begins to increase, and by extension circuit current decreases.
