Xander was traveling at a final velocity of 4.5 m/s for 3.5 seconds. Finley was traveling at a final velocity of 3.6 m/s for 4.2

seconds. Max was traveling at a final velocity of 7.3 m/s for 1.2 seconds. They all started at the same location from rest. Which lists them from least to most acceleration?

Answer: Finley, Xander, Max

Explanation:

The acceleration of each runner is given by:

a=\frac{v-u}{t}

where

v is the final velocity

u is the initial velocity

t is the time taken

- Xander: his acceleration is a=\frac{4.5 m/s-0}{3.5 s}=1.29 m/s^2

- Finley: his acceleration is a=\frac{3.6 m/s-0}{4.2 s}=0.86 m/s^2

- Max: his acceleration is a=\frac{7.3 m/s-0}{1.2 s}=6.08 m/s^2

So, in order from least to most acceleration:

Finley, Xander, Max

Arrange the following substances in order of decreasing magnitude of lattice energy. Rank the compounds in order of decreasing m
Ivan

Answer:MgO>CaO>NaF>KCl

Explanation:

The lattice energy is one that depend on the attraction between oppositely charged ions in a compound/substance.

Following up with this the greatest forces of attraction will exist between ions that have the smallest radii.

And, because the attraction depends on the product of the charges, we prioritize ions with the greatest charge.

The smallest pair of ions will be able to get closest to each other relative to others. This implied that the smallest distance between centres will have the largest lattice energies relative to others.

Answer:

Velocity of sound is 512 m/s

Explanation:

for first resonance condition we know that

\frac{\lambda}{4} = L

\frac{\lambda}{4} = 0.40

\lambda = 1.6 m

now the frequency is given as

f = 320 Hz

now to find the velocity of sound we have

v = \lambda f

v = 1.6 (320)

v = 512 m/s
