Answer:
4 miles north
Explanation:
Initially Scott travels 5 miles north at this point his displacement is 5 miles toward north
then he goes 3 miles south. which makes his displacement 2 miles (5 - 3 = 2) towards north as north and south are opposite directions.
finally he travels 2 miles due north.so his final displacement is
2 miles + 2 miles = 4 miles towards north direction
Answer:
Most metals have <u>luster</u> which means they <u>reflect</u> light
Explanation:
When light, which is made up of energetic photons, comes in contact with the surface of a metal, it is absorbed due to the corresponding energy gaps present between the metal orbital. The absorbed photons results in the raising of the energy levels of electrons within an atom of the metal which later drop back to a lower energy level and re-emit the photons which can now be observed as the metallic luster.
Answer:
The answer is "As 
, at high-temperature 
and When
."
Explanation:
The equation for the reaction is:
At equilibrium,
When k=5.8(>1), the value of 
would be positive
So, 
is negative (< 0)
So if K > l, 
If the reaction is not in equilibrium so the equation is :
=
Substituting the expression:
It is the positive value for all temperatures.
So, As Q = 336, at the high temperature .
Option D
The car is accelerating, because if it were at rest you wouldn't see the line, and if the car was going at constant speed (forwards or backwards) then the line would be straight.

Answer:
Original volume=3L
Explanation:
Assuming the gas in the ballon is ideal and the temperature does not vary with height we have the gas law as
PV=nRT
Here RHS is constant in both the conditions which means
PV=constant
Given P1=1 atm V1=V P2=0.75atm V2=4L
P1V1=P2V2
V=3L
The initial volume of the gas is 3L
