Constructive interference means that the waves combine instead of negate. if they are both amplitude x, adding them together would result in 2x, or doubling the amplitude of one of the waves
Answer:
-10837 J
Explanation:
The law of conservation of momentum states that the initial total momentum is equal to the final total momentum, so:
where
m = 22.3 g = 0.0223 kg is the mass of the bullet
is the initial velocity of the bullet
M = 1 kg is the mass of the block
is the initial velocity of the block
is the final velocity of the bullet
is the final velocity of the block
Solving for we find
The total kinetic energy before the collision is:
And the total kinetic energy after the collision is:
So, the change in kinetic energy is
Answer:
ok so u 4394 and 2340234 dhw04436445 ?! there
Explanation:
Answer:
It has a mass of 40 kg.
Explanation:
Because Force = mass x Acceleration or F = m a, we could say that the mass is force/acceleration which in your case is 2,400/60 which equals 40 kg.
Answer:
The dependant variable is obvrioulsy going to be the temperature of the watch, and the independan variable is going to be the amount of water ebing poured into the cups.
Explanation:
The temperature is the dependant variable by how it is the thing being observed, or recorded. Your independant variables could be a few things from wha information I have but it could be either, the amount of water being poured into the cups, the temperature of the water being poured, or the amount of time between each new temperature of wather bing poured into the cups.
