Answer:
B. blocks 2 & 3.
Explanation:
Block 1 has equal & opposite forces acting on it.
Block 2 has 5N on one side, 3N on the other. It will move in the direction the 5N of force is pushing.
Block 3 has no opposing force.
Answer:
588 J
Explanation:
PE (potential energy) = (mass) x (gravity) x (height)
mass = 12 kg
gravity = 9.8m/s^2
height = 5 m
PE = (12) x (9.8) x (5) = 588 J (Joules)
Answer:
The arrange marriage and love marriage is same or different from each other "one is about loving and then getting committed and another one is getting committed and then loving,so in the either way both are same."
Explanation:
There is no difference at all! Because eventually, in both the cases, people manage to stay together and share the responsibilities. What actually matters is that, if Love happened.
Let’s put it this way. Two people fell in love and they get married, but why is that the same couple would want to separate later? Let’s take another example. Two people who don’t have any idea of each other’s existence get married. why is that they choose to live together forever? Love becomes the reason for any split or patch.
When two people are in love everything becomes easy. A relationship doesn’t look hard, in fact I have friends who have a wonderful married life and people still don’t bother to find if that’s a love or an arranged match. Few of them choose partners of their own and few of them fell head over heels in love with their spouse, but all of them look as if they are on an extended holiday.
A) 1.55
The speed of light in a medium is given by:
where
is the speed of light in a vacuum
n is the refractive index of the material
In this problem, the speed of light in quartz is
So we can re-arrange the previous formula to find n, the index of refraction of quartz:
B) 550.3 nm
The relationship between the wavelength of the light in air and in quartz is
where
is the wavelenght in quartz
is the wavelength in air
n is the refractive index
For the light in this problem, we have
Therefore, we can re-arrange the equation to find , the wavelength in air:
Answer:
Hey there!
Because you are compressing the spring, these are compressional waves.
Let me know if this helps :)
