Answer:
Explanation:
A. Using
Sinစ= y/ L = 0.013/2.7= 0.00481
စ=0.28°
B.here we use
Alpha= πsinစa/lambda
= π x (0.0351)sin(0.28)/588E-9m
= 9.1*10^-2rad
C.we use
I(စ)/Im= (sin alpha/alpha) ²
So
{= (sin0.091/0.091)²
= 3*10^-4
Answer:
7 deg
Explanation:
= mass of the rod = 
= weight of the rod = 
= spring constant for left spring = 
= spring constant for right spring = 
= stretch in the left spring
= stretch in the right spring
= length of the rod = 0.75 m
= Angle the rod makes with the horizontal
Using equilibrium of force in vertical direction for left spring
Using equilibrium of force in vertical direction for right spring
Angle made with the horizontal is given as
Answer:
24000N
Explanation:
The mass of the object stays the same, regardless of its gravitational field strength. But, weight=mass*gravitational field strength.
So, the gravitational field strength on Earth is 10N. 2400*10=24000.
hope this helps
Answer:
d) The molecules in A have more average kinetic energy per molecule than those in B
e) The molecules in A are moving faster than those in B
Explanation:
Given that
Size of boxes are equal
So volume of boxes = V
Temperature in box A =50°C = 323 k
Temperature in box B = 10°C = 283 K
We know that for ideal gas
P V = m R T
The mass of gases is not given so we can not say that which have high temperature.Also be can not say that which box have more molecule.
We know that average kinetic energy is directly proportional to the absolute temperature of gas that is why we can say that box A will have more kinetic energy because it have high temperature.We know that is gas have high kinetic energy then we can say that it have high moving velocity.
So the option d and e is correct.
d) The molecules in A have more average kinetic energy per molecule than those in B
e) The molecules in A are moving faster than those in B
