Answer:
1kg steam will have the maximum energy
C.
<span>Each atom has 19 proton
</span> the atomic number is the same as protons
Explanation:
mass, m = 5kg
initial velocity, u = 16m/s
final velocuty, v = -22m/s
change in momentum, ∆p = ?
∆p = m (v-u)
5(-22-16)
5(38)
∆p = 190kgm/s
check the calculations!
Thermal equilibrium is achieved when two objects or systems reach the same temperature and cease to exchange energy through heat. When two objects are placed together, the object with more heat energy will lose that energy to the object with less heat energy.
Given Information:
Radius = r₁ = 150 m
Radius = r₂ = 73 m
Maximum speed = v₁ = 28.0 m/s
Required Information:
Maximum speed = v₂ = ?
Answer:
Maximum speed v₂ = 19.53 m/s
Explanation:
The maximum acceleration of the truck is
a = v²₁/r₁
a = 28²/150
a = 5.226 m/s²
Now if we change the radius to r₂ = 73 m
Then the maximum speed of the truck is
v₂ = √a*r₂
v₂ = √5.226*73
v₂ = 19.53 m/s
So the speed of the truck is decreased when the radius of curve is decreased.
