Answer:
Explanation:
Energy consumed per day = (2.2 x 1.5 + 4 x .075 x 5 + 2.5 x 1 + 2.3 )kWh
= 3.3 + 1.5 + 2.5 + 2.3
= 9.6 kWh
Energy consumed in a month = 9.6 x 30
= 288 kWh
cost = 288 x .105
= $ 30.24
b ) 288 kWh = 288 x 60 kW
= (288 x 60)/ 4.2 kcal
= 4114.28 kcal
coal required per month = ( 4114.28 / 7500) x (1 / .37 )
= 1.48 kg
coal required per month= 1.48 x 12
=17.76 kg
=
Wave speed (m/s) = frequency (Hz) x wave length (m)
=0.2 x 100= 20m/s
Answer:
i don't really know the exact answer but i would say something like earthquakes or steam/excessive heat
Explanation:
The formula for energy of motion is KE = .5 x m x v^2
Ke= Kinetic Energy in Joules
m = Mass in Kilograms
v = Velocity in Meters per Second
Answer:
Distance = 13.9 meters
Explanation:
Given the following data;
Maximum speed = 150 km/hr to meters per seconds = 150 * 1000/3600 = 41.67 m/s
Decelerating speed = 3m/s
To find the distance travelled with this speed;
Distance = maximum speed/decelerating speed
Distance = 41.67/3
Distance = 13.9 meters
Therefore, the bus would travel a distance of 13.9 meters before stopping.
