Answer:3.92475J
Explanation:
ideal gas equation
PV=nrT
P=pressure
V=volume 9*5*14=630m^3
n=mole
Mole=mass/molecular mass
molecular mass of air=28.1g/mol
R=gas constant
T=temperature in kelvin
1.01*10^5*630=(m/28)*8.314j/molK *273K
784959.5677356082g
784.95kg
Kinetic energy=0.5*m*v^2
Velocity of air
0.5*784.95kg*0.1^2
K.E=3.92475J

Answer:
Take a magnet and move it over the cup
Explanation:
Since there are metals also in the cup they would be attracted by the magnet leaving the plastic clips only in the cup
Answer
given,
mass of car = 800 kg
mass of truck = 1900 kg
force acting = 4900 N
a) F = (m₁+ m₂ ) a
a = 1.815 m/s²
a) force exerted by the car on the truck
F = 3448.5 N
b) According to newtons third law
Force exerted by the truck on the car will be same.
Force of the truck on the car = F = 3448.5 N
