Answer:
because the bowling ball has a heavier mass, it will have more energy on the decent
Explanation:
Answer:
20.05 seconds
Explanation:
Given that:
v² = u² + 2as
v = final velocity
u = initial velocity
a = acceleration
s = distance
a = negative acceleration = - 0.43
s = distance = 86.5
v = 0
0 - 2(0.43)(86.5) = u²
74.39 = v²
U = sqrt(74.39)
U = 8.6249
From ;
t = Time in seconds
t = (v - u) / a
t = (0 - 8.6249) / - 0.43
t = 20.057
Answer:
The net calorific value of the fuel 1 is 40000 kilojoules per kilogram.
The net calorific value of the fuel 2 is 50000 kilojoules per kilogram.
Explanation:
The net calorific value is equal to the heat produced (
), in kilojoules, divided by the mass of the burnt fuel (
). We proceed to calculate the net calorific value of each fuel:
Fuel 1 (
, 
)
The net calorific value of the fuel 1 is 40000 kilojoules per kilogram.
Fuel 2 (
, 
)
The net calorific value of the fuel 2 is 50000 kilojoules per kilogram.
True
It goes triassic, Jurassic, Cretaceous
A main sequence star burns hydrogen to helium. Once a main sequence star exhausts all of the hydrogen, it begins to expand and burn helium causing if to become a red giant.
