Wave speed = (wavelength) x (frequency)
= (45 meters) x (9 per second)
= 405 meters per second .
Answer:
The Andromeda is a galaxy which is nearest to the milky way. It is also named as Messier 31 or M31 or NGC 224. It is a spiral galaxy located at a distance of approximately 2.5 million light years from earth.
another name Andromeda in Hindi is Vaikunth.
Answer:
Explained
Explanation:
1.Each of the spring scale will read 10N,considering acceleration due to gravity as 10 m/s^2
2.Each of the spring scale will read 10N because each string exerts a force of 10 N to counterbalance the force of 1 kg mass attached to it. This means the tension on the both side of the string is 10 N. So the scale will read 10 N. Also as spring balances are attached in series and kept on table so both spring balances will read same readings.
Answer:
The balance will be upset and it will tip to the side of the still pumped ballon.
Explanation:
Given that the balloons are pumped to more than atmospheric pressure it means that the air inside has a higher density than the air outside. If you punture one balloon the air will be released and now you have on both sides the weight of the balloons itselves, but on the side of the still pumped balloon you will have a greater amount of air (is more dense) so more weight. Considering this, the balance will be upset and it will tip to the side of the still pumped ballon.
Answer:
D
Explanation:
The left side of the graph is the reactants, C(s)+2S(s). The right side of the graph is the product, CS₂(l). Adding energy to the reactants will yield the product, so the product must have more energy than the reactants. Therefore, the answer must be D.
When energy is absorbed by a reaction rather than released, it's called an endothermic reaction.
