Answer:
12 miles per hour
Explanation:
time is equal to speed times distance
Answer:
The distance traveled by the car is 60 miles and the displacement of the car is 20 miles in the north direction.
Explanation:
The distance is the total length of the car's path.
d = 40 mi + 20 mi
d = 60 mi
The displacement is the distance between the starting position and the final position.
x = (40 − 20) mi N
x = 20 mi N
Answer:
B
Explanation:
The others are natural growth developments
Answer:
P=11.126 atm
Explanation:
We are given that a compressed gas cylinder containing 1.50 mol methane
Volume of methane in a gas cylinder =3.3 L
Temperature =
We have to find the pressure exert by gas on cylinder
Using ideal gas equation
PV =nRT
Where R= gas constant=0.0821 L-atm/K mol
Substitute all given values
Then we get


P=11.126 atm
Hence, the pressure exert by the gas on cylinder =11.126 atm
Answer:
Big bang
Explanation:
During the Big Bang, all of the space, time, matter, and energy in the Universe was created. This giant explosion hurled matter in all directions and caused space itself to expand. As the Universe cooled, the material in it combined to form galaxies, stars, and planets.
