<h2>
The balloon is moving when it is halfway down the building at 20.78 m/s.</h2>
Explanation:
We have equation of motion v² = u² + 2as
Initial velocity, u = 0 m/s
Acceleration, a = 9.81 m/s²
Displacement, s = 0.5 x 44 = 22 m
Substituting
v² = u² + 2as
v² = 0² + 2 x 9.81 x 22
v² = 431.64
v = 20.78 m/s
Velocity at 22 m = 20.78 m/s
The balloon is moving when it is halfway down the building at 20.78 m/s.
Explanation:
As temperature increases additional heat energy is applied to the consituent part of a solid which cause additional molecular motion.
Because tropical moist forests are used for agricultural, the thin soil cannot support continuous cropping, while deciduous forests can regrow quickly.
Answer:
mars is a fourth planet of the sun and the second planet in the solar system
moon is a natural satellite of the earth it isthe fifth largest moon in the solar system
Answer:
the diffrence between the 2 are
aerobic respiration : requires oxogen, occurs in the mitochondria of cells, produces a lots of ATP per glucose molecule, and used when heart rate and breathing rate rise
anaerobic respiration : occurs in the cytoplasm of cells, dosen't require oxogen, used during the first 1 -2 minutes of exersise , and produces less ATP per glucose molecule
i hope this helps and i hope you had a great day
