The bullet falls 0.25m
The answer is -0.25m because it is falling, therefore it is negative.
Explanation:
t = dy/vy = 180m/800m/s = 0.23 secs
dy = 1/2 gt^2 = -0.25m
1. False
2. Positive
I’m just joking I don’t know the answersss
Answer: 653.33 nm ; 1875, 24 nm
Explanation: For the first case we have to use the Balmer series for the hydrogen when the atom falls from the n = 3 to the n = 2. So for the second transtions for the hydrogen we use the Paschen serie. To do the calculation we need to know the Ryberg constant that is equal to 1.097 * 10^7 m^-1. In the attach is shown the expression for spectral series used for calculation.
Answer:
Explanation:
I'm pretty sure the answer would be deductive reasoning. Deductive reasoning relies on making logical premises and basing a conclusion around those premises. It does not rely on making inferences and then assuming those inferences to be true.
1 particles have got forces of attraction between them
2 they vibrate and rotate at a fixed point
3 they gan heat energy in order for them to melt
4 particles are closely packed together
