Answer:
0.00095%
Explanation:
Mass of coal needed every day = Mass needed every hour × 24
Thermal energy released per hour = Mass × Heat of combustion
Power released per second = Energy / 3600 seconds
Thermal efficiency = (Electrical power / Mechanical power) × 100
Thermal efficiency of the plant is 0.00095%
Answer:
1.89 m
Explanation:
h = 2 m
u = 3 m/s
θ = 45
Let t be the time taken
use second equation of motion in vertical direction
h = u t + 1/2 a t^2
- 2 = 3 Sin 45 t - 1/2 x 9.8 x t^2
- 2 = 2.12 t - 4.9 t^2
4.9 t^2 - 2.12 t - 2 = 0
By solving we get
t = 0.89 sec
Let x be the horizontal distance travelled
x = u Cos 45 x t
x = 3 Cos 45 x 0.89 = 1.89 m

Answer:
Devices like smartphones can interface with cars and leave evidence
Explanation:
Vehicle system forensic relates to digital data stored in a vehicles system.
Bluetooth connection times can be used to figure out at what time the owner was near his car. e.g. between a smart-watch and car infotainment system
