We Know: MA = d₁ / d₂
Here, d₁ = 4
d₂ = 10-4 = 6
Substitute their values into the expression:
MA = 4/6
MA = 2/3
So, Your Answer would be 2/3
Hope this helps!
A giant (massive) planet close to the star is expected to cause the largest Doppler shift in the star's spectrum.
<h3>What is the Doppler Shift Method for Detecting Exoplanets?</h3>
- Doppler spectroscopy is used to capture periodic velocity shifts in stellar spectra caused by orbiting giant planets. (This method is also known as the radial velocity method.)
- The Doppler method, which is most commonly used to find exoplanets, is most suitable to look for very massive planets orbiting near their parent stars
<h3>What does the Doppler method tell us about planets? </h3>
The Doppler shift data can tell us something about the mass of the planet and the shape of its orbit. Since the Doppler shift only knows how fast it approaches and moves away from Earth, it is not possible to determine the exact mass of the planet without knowing the inclination of its orbit. Doppler data give a lower bound on mass.

Answer:
This distance is measured from the center of the earth r = 3.4 10⁸ m
Explanation:
The equation for gravitational attraction force is
F = G m1 m2 / r²
Where g is the universal gravitation constant, m are the masses of the body and r is the distance between them, remember that this force is always attractive
Let's write the sum of force on the ship and place the condition that is balanced
F1 -F2 = 0
F1 = F2
Let's write this equation for our case
G m Me / r² = G m Mm / (r'.)²
The distance r is measured from the center of the earth and the distance r' is measured from the center of the moon,
r' = 3.85 10⁸ m
Let's simplify and calculate the distance
Me / r² = Mm / / (3.85 108- r)²
Me / Mm (3.85 108- r)² = r²
√ 81.4 (3.85 108 -r) = r
√ 81.4 3.85 108 = r (1 + √ 81.4)
34.74 108 = r (10.02)
r = 34.74 10⁸ / 10.2
r = 3.4 10⁸ m
This distance is measured from the center of the earth
Answer:E. an object will remain in uniform motion unless acted upon by a force
Explanation:
Answer:
v = 6.95 m/s
Explanation:
Given that,
A diver is on a board 1.80 m above the water, s = 1.8 m
The initial speed of the diver, u = 3.62 m/s
Let v is the speed with which she hit the water. It will move under the action of gravity. Using the equation of motion as follows :
So, she will hit the water with a speed of 6.95 m/s.
