Answer:
1) Atmosphere
Explanation: because if you think about it the only real explaination is atmosphere.
There are 2.1077x10^24 atoms of sulfur in 3.50 mols of sulfur.
Answer:
5 atoms of Boron
Explanation:
Boron makes up approximately 15.944% of the mass and the rest of the 84.056% is Fluorine. There is 5 Atoms because Boron atomic mass is 10.811 in 1 molecule of BF3 and you wanted 5 Molecules.
The answer to the question is shown below:
We all know that formula for solving work done is the force multiplied by distance covered:
Work done = Force x distance
Distance = 5m
Force = 500 N
Work done = 500 N * 5m
Work done = 2500 J
Answer:
Explanation:
Given that,
Radius of the wheel, r = 20 cm = 0.2 m
Initial speed of the wheel, 
Displacement, 
To find,
The angular acceleration and the distance covered by the car.
Solution,
Let 
is the angular acceleration of the car. Using equation of rotational kinematics as :
Let t is the time taken by the car before coming to rest.
t = 30.39 seconds
Let v is the linear velocity of the car. So,
v = 150.79 m/s
Let d is the distance covered by the car. It can be calculated as :
d = 4582.5 meters
or
d = 4.58 km
