1 volt = 1 joule per coulomb
50 volts = 50 joules per coulomb
50 joules/coulomb times 6 coulombs = 300 joules
The law of conservation tells us that no mass is lost. This is true because when wood burns or turns into ash, some of it is escaped as gases like carbon dioxide and water vapor into air . If we calculate the mass of these atmospheric gases that evolved when the wood turned into ash, we would find that the total mass of all these substances including the ash is equal to the log of wood.
Answer:
0.11m/s
Explanation:
To solve the exercise it is necessary to apply the concepts related to the conservation of both: kinetic and spring energy(Elastic potential energy), in this way
Kinetic Energy = Elastic potential energy


Where,
m=mass
v=velocity
k=spring constant
x=amount of compression
Re-arrange the equation to find the velocity we have,




Therefore the maximum speed of the bananas is 0.11m/s
Answer:
28.2 m/s
Explanation:
The range of a projectile launched from the ground is given by:

where
v is the initial speed
g = 9.8 m/s^2 is the acceleration of gravity
is the angle at which the projectile is thrown
In this problem we have
d = 81.1 m is the range
is the angle
Solving for v, we find the speed of the projectile:

Answer:
A & B
Explanation:
A & B Would be the right answer since Morse code cannot be represented through the height of the fire.
