Answer: 10.02m
Explanation: Given
M1 = 26.3kg
M2 = 52.5kg
d = 5m
If the systems centre of mass does not change, the two skaters will definitely meet at the centre of mass.
If the 26.3kg skater is a m away from the centre of the mass, then the 52.5kg skater is (5-a) m away from the centre of the mass. Thus,
M1a + M2(5-a) = 0
26.3a + 52.5(5-a) = 0
26.3 a + 262.5 - 52.5a = 0
-26.2a + 262.5 = 0
26.2a = 262.5
a = 262.5/26.2
a = 10.02m
Answer:
See the explanation below.
Explanation:
A species is invasive can be spread, naturally either by the behavior of the species, or introduced accidentally or voluntarily by man.
The invasive species increases its density in the occupied area or colonizes new territories over time.
That an invasive species is harmful means that it produces significant changes in the composition, structure or processes of natural or semi-natural ecosystems, endangering native biological diversity.
Uncontrolled reproduction of this invasive species also increases the risk of control and extermination of the species, due to the acclimatization of the new species in the environment as well as possible exponential reproduction.
For the rest 3 km
Bholu need to run in 5 minutes so
He need to 3 × 1000 / 5 × 60 m/s
3000/ 300 = 10 m/s
So , his speed should be 1 m/s to reach in 5 minute
mark as brainliest 5 star
<h2>Answer:</h2>
The speed of atoms depends upon:
- Temperature: Speed of atom is directly proportional to the temperature of atoms.
- Pressure : It is also directly proportional to the speed of an atom.
- Volume of gas : As the volume of gas increases, collision between atoms increases with increasing the speed of atom
- Number of atoms surrounding: More number of atoms leads to more collisions, increasing speed of atoms.
