Answer:
X
Explanation:
v=u+at but t is constant so
a=v-u
for x
a=29-10
a=19
which marks the greater acceleration
R is the distance from the center of the Earth to the object in orbit. So, the object isfalling<span> towards the Earth, but just keeps missing the Earth. This is the real reason astronauts float inside the International </span>Space Station<span> (</span>ISS) - they, and the vehicle are in free-fall<span>.

Answer:
An isotope is one of two or more species of atoms of a chemical element with the same atomic number and position in the periodic table and nearly identical chemical behavior but with different atomic masses and physical properties. In medicine, for example, cobalt-60 is extensively employed as a radiation source to arrest the development of cancer. Other radioactive isotopes are used as tracers for diagnostic purposes as well as in research on metabolic processes.
Hope this helps! Please let me know if you need more help, or if you think my answer is incorrect. Brainliest would be MUCH appreciated. Have a wonderful day!
The net force on the box is:
50 + 30 - 65
= 15 Newtons
This can be used in conjunction with
F = ma
to calculate the acceleration of the box if its mass is known.
1) The mass has the same value before and after the impact (We will neglect the microscopic effects in which there may be a minimum molecular loss of the material) so the equation will be
If we put the mass in one side of the expression (or just cancel directly) we have that
2) We must clear from the equation previously found the number two that is dividing the expression (It would go to the other side of the equation to multiply) and the exponent that would pass to the other of the expression as root therefore
3) We must simply replace the given values, the height is 3.67m and the gravity on the ground is therefore
