Answer:
The environment is warmed by the light throughout the day, such that the temperature increases. The weather is decreasing and the temperature decreases in the night as the sun falls. There was a misunderstanding. Thanks to the density, the atmosphere becomes densest on the earth. The air becomes colder and colder when you move up.

Answer:
r = 1.45 Å
Explanation:
given,
λ = 1.436 Å
θ = 20.62°
d = a
n = 2
metal gold crystallizes in a face centered cubic unit cell
Radius of the gold atom = ?
using Bragg's Law
n λ = 2 d sin θ
2 x 1.436 Å = 2 a sin 20.62°
a = 4.077 Å
We know relation of radius for face centered cubic unit cell
r = 1.45 Å
the radius of a(n) gold atom. is equal to 1.45 Å
Acceleration is defined as rate of change in velocity
So we can write its formula as
here we know that
= final velocity = 56 m/s
= initial velocity = 7.6 m/s
t = time interval to change the velocity = 3 s
now we will plug in all values in the above equation
so here roller coaster will accelerate at rate of 16 m/s^2 and hence correct answer is "option d"
We know that displacement is the length of straight line joining the initial position with the final position. as lisa walks around the block once, she comes back to her initial position here she started from, hence the initial and position of lisa is same. so her displacement is zero.
We know that distance is the length of the actual path followed by object between initial and final position. As lisa walks around the block once, she travels 1 mile. hence the distance traveled by lisa is 1 mile.
displacement : 0
distance : 1 mile
