Answer:
64.1°
Explanation:
Coefficient of friction = Horizontally resolved pushing force divided by Moving force
Coefficient of friction is 0.437
Resolving pushing force to horizontal = Moving force * Cos ∅
Therefore, 0.437 = Cos ∅
and ∅ = Arch Cos 0.437 = 64.1°
Answer: The piezoelectric effect describes the property of certain solids to generate an electrical charge under mechanical stress. The actuating force modifies the microscopic structure of the body; dipoles are created between which a voltage builds up. And Their positive and negative charges complement each other creating two types of electricity: static electricity
Explanation:
Answer:
The value is 
Explanation:
From the question we are told that
The total time of flight is 
Generally from kinematic equation
So v is the velocity at maximum height and the value is v = 0 m/s
So
=> 
Here u is the initial velocity of the dart as it leaves that gun
Gnerally the horizontal range of the dart is mathematically represented as
For maximum horizontal range the value of 
So
=>
Answer:
liquid to gas

Answer:
Explanation:
Incandescent bulbs are extremely inefficient because 90% of the energy is wasted as heat, with only 10% being converted to visible light. This gives incandescent bulbs a luminous efficiency rating of around 2%. Ultimately, incandescent bulbs perform better as heaters than as light sources.
