Answer:
2 sec
Explanation
travel speed is = 10 m/sec
so for 20 meter = 20/10 = 2 sec
The protons are positively charged, the electrons are negatively charged, and the neutrons are neutral.Opposite charges attract each other (negative to positive). Like charges repel each other (positive to positive or negative to negative).
Answer:
True
Explanation:
Reproduction is one of the essential characteristics of all living beings. However, if they reproduce to their full capability, the number of offspring would be higher than the available resource. Due to this reason there is always shortage of resources and hence competition arises among the species.
The fit species survive among all the competing species while the remaining weak species die. As Darwin also said that species have the ability to reproduce uncontrollably therefore, competition among the species for survival is a mode of population regulation
Hence, the given statement is true
