Answer:
The Answer is A) Metal X aluminium; Metal Y platinum
Explanation:
The behavior of the bimetallic strip depends on the coefficient of thermal expansion. Where the coefficient of the metal X should be greater than the coefficient of thermal expansion for metal Y. In the attached image we can see the effect of this particular behavior.
In the only case where the coefficient of thermal expansion of the metal X is greater than the used in the metal Y is in case A.
Here we have:
Answer:
1,365 miles
Explanation:
i multiplied 455 x 3 because it traveled 455 miles an hour for three hours.
Answer:
It increases by four times the initial amplitude.
Explanation:
The amplitude of a sounde is inversely proportional to the square of the distance between the listener and the sound source:
In this problem, the distance is decreased to hald the initial distance, so we can write
therefore, the new amplitude will be
So, the amplitude increases by a factor 4.
Any vector can be written as components along positive X and positive Y axes.
So vector B can be written as , where is the angle between vector and positive X axis
So vector B =
So components of vector B along X -axis =-6.74 m
along Y-axis = 16.69 m
Answer:
Hi,
I can't tell what it says where you have written 'with the horizontal giving ____'.
I am unable to tell what the word after 'giving' is. Please ix it ASAP.
Thank you
