Answer:
3 m/s
Explanation:
Parameters given:
Mass of first bowling pin, m = 1.7 kg
Initial velocity of first bowling pin, u = 3.8 m/s
Final velocity of first bowling pin, v = 0.8 m/s
Mass of second bowling pin, M = 1.7 kg
Initial velocity of second bowling pin, U = 0 m/s
Let the final velocity of the second bowling pin be V
Using the principle of conservation of momentum:
Total initial momentum = Total final momentum
m*u + M*U = m*v + M*V
(1.7 * 3.8) + 0 = (1.7 * 0.8) + (1.7 * V)
6.46 = 1.36 + 1.7V
1.7V = 5.1
V = 5.1/1.7 = 3 m/s
Explanation:
For, heating purposes more the quantity of water more will be the heating. Clearly, underground heating would have more water and hence, it will have edge over the water heater system.
Moreover, for things at the same temperature, the thing with more molecules has more total kinetic energy (thermal energy) than the thing with fewer molecules. The groundwater heating system uses heat from the heat stored naturally in groundwater or aquifers. Thus, saving the cost of power required to heat in normal water heater.
Answer:
Explanation:
The instantaneous velocity of a point mass that executes a simple harmonic movement is given by:
Where:
Express the amplitude in meters:
The angular frequency can be found using the next equation:
Using the data provided:
At the equilibrium position:
It's c/f, in which c is the speed of light (300000 m/s)
