Answer:
What is butter
Explanation:
Answer:
7.2 seconds
Explanation:
The formula is a = v/t, or acceleration = the change in velocity over the change in time.
In this case, you do simple algebra to rearrange the formula to solve for time: t = v/a, time = velocity/acceleration.
time = 18 m/s / 2.5 m/s^2 = 7.2s
Answer:
Quantum mechanical model = involves finding an electron somewhere in a specific orbital.
Explanation:
The quantum mechanical model of an atom involves finding an electron somewhere in a specific orbital. This method is completely based on mathematical calculations. It defines the probability of finding an electron rather than its reality.
These are designated by some letters like s, p, d, f...... and the corresponding energy levels are 1st, 2nd, 3rd and so on.....
So, the correct option is (c) "involves finding an electron somewhere in a specific orbital".
Angular frequency of pendulum is given by
for both pendulum we have
For other pendulum
now we have relate angular frequency given as
[tex\omega_1 - \omega_2 = 3.13 - 2.98 = 0.15 rad/s[/tex]
now time taken to become in phase again is given as
now number of oscillations complete in above time
b. 0.78
c. 1.28
d. 12.5
Answer:
128 m
Explanation:
displacement = velocity x time
32 x 4 = 128
Answer:
Displacement= velocity X time
= 32 X 4
=128m/s
