In recent years, astronomers have found planets orbiting nearby stars that are quite different from planets in our solar system.

Kepler-12b, has a diameter that is 1.7 times that of Jupiter (RJupiter = 6.99 × 107 m), but a mass that is only 0.43 that of Jupiter (MJupiter = 1.90 × 1027 kg ).

Answer:

g= 3.86 m/s^2

Explanation:

given : Kepler-12b, has a diameter that is 1.7 times that of Jupiter (R_Jupiter = 6.99 × 10^7 m), but a mass that is only 0.43 that of Jupiter (M_Jupiter = 1.90 × 10^27 kg ).

to calculate gravity we use the formula

g = GM/r^2

g = 6.67×10^-11 × 0.43×1.9×10^27/( 1.7×6.99×10^7)^2

g = 3.859 ~ 3.86 m/s^2

A model rocket blasts off and moves upward with an acceleration of 12 m/s2 until it reaches a height of 26 m. at that height, it
Diano4ka-milaya [45]

initial acceleration of rocket is given as

a = 12 m/s^2

h = 26 m

now we can use kinematics to find its speed

v_f^2 - v_i^2 = 2 a h

v_f^2 - 0 = 2 * 12*26

v_f = 24.98 m/s

now after this it will be under free fall

so now again using kinematics

v_f = 0

at maximum height

v_f^2 - v_i^2 = 2 a s

0 - 24.98^2 = 2 * (-9.8)* h

h = 31.8 m

total height from the ground = 31.8 + 26 = 57.8 m

Part b)

now after reaching highest height it will fall to ground

So in order to find the speed we can use kinematics again

v_f^2 - v_i^2 = 2 a d

v_f^2 - 0 = 2*9.8*57.8

v_f = 33.67 m/s

Part c)

first rocket accelerate to reach height 26 meter and speed becomes 24.98 m/s

now we have

v_f - v_i = a t

24.98 - 0 = 12*t_1

t_1 = 2.1 s

after this it will reach to highest point and final speed becomes zero

v_f - v_i = at

0 - 24.98 = -9.8 * t

t_2 = 2.55 s

now from this it will fall back to ground and reach to final speed 33.67 m/s

now we have

v_f - v_i = at

33.67 - 0 = 9.8 * t

t_3 = 3.44 s

so total time is given as

<em>t = 3.44 + 2.55 + 2.1 = 8.1 s</em>

Rock fragments that are cemented together and compacted over time turn into sedimentary rock.

the whole process can be summed up as the combination of weathering of rocks to form sediments, transport of the sediments to form deposits, cementation of deposits to forms the sedimentary rocks.

What is sunlight composed of
san4es73 [151]

Answer:

Roughly three quarters of the Sun's mass consists of hydrogen (~73%); the rest is mostly helium (~25%), with much smaller quantities of heavier elements, including oxygen, carbon, neon, and iron. The Sun is a G-type main-sequence star (G2V) based on its spectral class.
