Power=20 watts
Answer:
the ball will go up 3s and down 3s
v=gt
where t=3s and g=9.8m/s^2
distance=v0(t)+(1/2)gt^2
where initial velocity (v0)=0
Explanation:
Answer: v= 330m/s
Explanation: the length (l) of an open closed pipe is related to the wavelength (λ) as shown in the formulae below
l = λ/4
where l = 0.55m, hence we have that
0.55 = λ/4
λ = 0.55*4
λ = 2.2m
from the question, it can be seen that the fundamental frequency is 150Hz.
Recall that we have v=fλ, where v = speed of wave, f= frequency, λ= wavelength
v =2.2 * 150
v = 330 m/s
The energy is involved in ionization, electron affinity etc
The following are the conditions that favor the creation of covalent bonds since they are generated by the mutual sharing of electrons:
- Electron affinity, first. If both atoms have a strong electron affinity, a covalent link is often preferred between them.
- The energy of ionization. The ionization energy of the two atoms participating in the bonding process should be high.
- Atomic Dimension. The atoms that form covalent bonds should have lower atomic sizes. Stronger covalent bonds are created when atoms have smaller atomic radii.
- Electronegativity. Both atoms' electronegativities ought to be high. The two atoms' electronegativities should differ as little as possible.
- In order to establish covalent bonds, the atoms' high ionization energy is involved.
