Answer:
V = 15.9512 dm³
Explanation:
Given data:
Pressure = P = 1.37 atm
Temperature = T= 315 K
Number of moles of nitrogen= n = 0.845 mol
Volume = V = ?
Formula:
PV = nRT
Now we will put the values in equation.
V = nRT/ P
V = ( 0.845 mol× 0.0821 dm³.atm.K⁻¹.mol⁻¹ × 315 K) / 1.37 atm
V = 21.853 dm³. atm/ 1.37 atm
V = 15.9512 dm³
<em>Molar mass of Argon, Ar = 39.95 g Mass of 1 atom, m = 39.95 / (6.023 * 10^23) = 6.64 * 10^(-23) g =6.64 * 10^(-26) Kg Now, Kinetic Energy, KE = (1/2) * m * v^2 where velocity,v = 650 m/s Mass of 1 atom, m = 6.64 *...</em>

Answer:
A. .2 M/s2
Explanation:
Force = mass x acceleration
The force is given as 20 N and tthe mass as 100kg
Solve for accelartion as 20/100 = .2
(Also wrong subject this is a Physics problem)
Answer:
B
Explanation:
weight , w= mg where m is the mass of the object (unit is kg ) and g is the gravitational force acting on the object ( unit is m/s^2 )
