Planet A;
m = the mass
Let r = the radius
Planet B:
Let M = the mass
The radius is 2r (twice the radius of planet A)
The surface gravitational acceleration of planets A and B (they have the same surface gravity) are
Answer: The mass of planet B is 4m.
<span>The inertia of an object increases if the mass is decreased. Inertia is the resistance of any physical object to a change in its state of motion or rest. It is represented numerically by an object's mass.</span>
Answer:
See below
Explanation:
- Venus Express (2005 - 14)
- Galileo (1989 - 90): As it flew by Venus on its way to Jupiter, it collected measurements of charged particles, dust and magnetism, infrared and ultraviolet spectral observation, data for infrared lower - atmosphere maps, and 81 camera images
- Magellan (1989 - 90)
- Vega 1 (1984 - 85)
- Vega 2 (1984 - 85)
- Venera 4 (1964): Atmosphere made up of entirely carbon dioxide, found that temperatures ranged from 40 degrees Celsius high up in the atmosphere to 280 degrees Celsius closer to the surface, and pressures ranged 15 to 22 atmospheres
- Venera 6 (1969)
- Venera 7 (1970): Became first spacecraft to return data from another planet and reported surface temperature of 475 degrees Celsius and atmospheric pressure 90 times greater than Earth's
- Venera 8 (1972)
- Venera 9 (1975)
- Venera 10 (1975): Transmitted images from the surface
- Venera 11 (1978): Sent back evidence of thunder and lightning as well as presence of carbon monoxide in lower altitude
- Venera 12 (1978)
- Venera 13 (1981 - 82): Returned first color images and found out the pressure was 84 times the pressure at sea level on Earth and the temperature was 457 degrees Celsius, before succumbing to them
- Venera 14 (1981 - 82): Sent back images of Venus
- Venera 15 (1983): Created radar map of Venus with Venera 16
- Venera 16 (1983)
- Pioneer Venus 1 (1978): Radar mapped nearly the entire planet, resolving features as small as 80 kilometers
- Pioneer Venus 2 (1978): Consisted of 4 separate atmospheric probes
- Mariner 2 (1962): Flyby attempt discovered ground temperatures as high as 428 degrees Celsius, but detected no water vapor or evidence of a magnetic field around planet
- Mariner 5 (1967): During flyby, measured surface temperature of 267 degrees Celsius
- Mariner 10 (1973 - 74): Took first ultraviolet images of Venus on way to Mercury
- Akatsuki/Venus Climate Orbiter (2010 - today)
These are just some of the successful attempts by probes at or near Venus.

Answer:
The time is 1206 years.
Explanation:
Given that,
Distance = 27000 ly
Speed = 0.9990c
We need to calculate the time
Using formula of speed
Put the value into the formula
We need to calculate the time dilation the clock on the spaceship
Using formula of dilation time
The time convert in years
We know that,
So, the time is
Hence, The time is 1206 years.
That would be carbonic acid
