B! Assume you are lifting weights... you are squatting 100 pounds, then you go to 200 pounds. The force of the mass/weight thus double Bc it is twice as hard to push it up!!
Hope this helps
Answer:
Destructive Interference Occurs
Explanation:
When two waves which have equal magnitudes but are in opposite directions, occupy the same region of space at the same time they cancel the effect of each other at the point of meeting. this phenomenon is known as the Destructive Interference. After passing the meeting point they move along their respective directions as if never met (see the diagram).
Answer:
orange and red
Explanation: hope this helps lemme know if its correct
Applying the concept of scalar product. We know that vectors must be multiplied in their respective corresponding component and then add the magnitude of said multiplications. That is, those corresponding to the component are multiplied with each other, then those corresponding to the component and so on. Finally said product is added.
The scalar product between the two vectors would be:
Therefore the scalar product between this two vectors is 5.74
Answer:
The change in volume is
Solution:
As per the question:
Coefficient of linear expansion of Copper,
Initial Temperature, T = = 273 K
Final Temperature, T' = = 273 + 100 = 373 K
Now,
Initial Volume of the block, V =
where
V' = Final volume
