Answer:
<u>-8</u>
Explanation:
if he starts at ten and takes 10 steps left he'll be at -10... then if he takes 2 steps to the right , he's at -8 on the number-line
Answer:
Explanation:
I'm going to assume that all the givens are in m/s. If I am correct, The orange line is speeding up. It is going from 4 m/s to 7 m/s. Its slant is from lower left to upper right. It is increasing in speed.
The green line is slowing down. It is going from 4 to 0 m/s. It's slant is from upper left to lower right.
The blue line is horizontal. It is neither slowing down or speeding up.
It’s a lot warmer now
Than it is during an ice age
<span>While you're going to the store, your acceleration changes. Some times it increases your overall speed sometimes it reduces it. Constant acceleration does not occur because it would mean that you would constantly accelerate and eventually go past the store. Even reduction of speed is a type of acceleration in physics. When you reach it, we can then calculate how much your velocity was on average and analyze how changing acceleration would've affected it.</span>
Answer:
1524 nm.
Explanation:
Angular separation of n th minima is given by the expression
Sin θ = n λ / a
Where λ is wavelength of light used and a is separation between two slits .
a = n λ / sin θ
For a to be minimum, sinθ has to be maximum .
maximum value of sin of any angle is 1 .
so the relation becomes as follows
a = n λ
n = 2 , λ = 762 nm.
a = 2 x 762 nm
= 1524 nm.
