(2) 2, is your answer. The Balmer and Lyman series releases different frequencies of the hydrogen atom energy emissions.
Answer:
B and D
Explanation:
I included the picture associated with the problem below:
Seeing as B and D are at the same level here, they posses the same amounts of kinetic energy. Another pair that would be correct, although it is not a choice, is A and E. This is because they too have the same kinetic energy (0J because they are stationary). Hope this helps! :)
Answer:
Cheetah cubs are in danger from predators like lions and hyenas which can track their prey by scent and so the mother and her cubs leave an area when their scent is too strong so that they are not hunted and the cubs survive.
Mother Cheetahs also train their cubs to hunt so that they may get food for themselves which will ensure their survival as well thus showing that both of these practices can impact on reproductive success.
I have no idea how too do that work sheet but try looking for the answer key online by searching for the name of the worksheet
Explanation:
Given that,
An ideal horizontal spring-mass system oscillates with a period of 0.60 seconds.
Mass is 3 kg but the spring constant is not known. We need to find the frequency of oscillations when this same spring and mass are arranged to hang vertically. We know that the relation between frequency and time period is inverse. Frequency is given by :
Hence, the correct option is (d) "none of the above".
