Answer:
The answer is h/4
Explanation:
When Peter collides with Fred, the collision is inelastic & they both proceed with a velocity of V/2.
let m represent the masses for Peter & Fred
v represent the initial velocity of Peter
V represent final velocity of both of them
mv + 3m × 0 = (m+m)V
V = v/2
Using the expression; H = v² / 2g .............Eqn 1
Upon substitution of V/2 into Eqn 1 above,
H = (V/2)² / 2g
H = (V²/4) ÷ 2g
Therefore height will be h/4
Answer:
Ultrasound is used by bats to navigate (move) and catch prey. Ultrasonic squeaks are produced by bats. These squeaks ponder prey and then return to the bat's ear. This provides bats with information about the location of prey, allowing them to catch it.
Explanation:
The speed of light in glass is slower than the speed of light through space.
Answer:
Amplitude increases with decreasing velocity.
Explanation:
At the same time, an increase in attention takes place
Answer:
The right approach will be Option C "Group 12".
Explanation:
- A table that further arranges the chemical components in addition to expanding the electron configuration. Elements possessing identical characteristics are positioned in almost the same section (column or group), although elements in almost the same row become positioned with a similar amount of electron spheres.
- Group 12 components therefore partially replaced (n − 1)d subshells, and therefore aren't metals, technically accurate. However, although much their chemistry seems to be comparable to something like the components throughout the d block which includes establishing themselves.
Some other options in question are not relevant to something like the given scenario. Because then the option here is just the right one.
