Physics
1 answer:
viktelen [127]3 years ago
3 0

Answer:

-0.8 m/s²

Explanation:

Acceleration is the slope of a velocity vs. time graph.

a = Δv / Δt

a = (0 m/s − 12 m/s) / (15 s − 0 s)

a = -0.8 m/s²

A large vessel of the diameter of 14 mm divides into two identical smaller vessels but the velocity of blood in
ycow [4]

Answer:

the diameter of the smaller vessels is 9.90 mm

Explanation:

The computation of the diameter of the smaller vessels is given below;

Given that

The larger vessel of the diameter is 14mm

So,

d1 = 7 mm

let us assume the diameter of the smaller artery is d2

Now we used the equation of continuity i.e.

v × pi × d1^2 = 2 × v × pi × d2^2

14^2 = 2 × d2^2

d2 = 9.90 mm

Hence, the diameter of the smaller vessels is 9.90 mm

Based on the bond energies given for each of the following which is the most stable? O=O 498 kJ/mol N≡N 946 kJ/mol C=C 614 kJ/mo
slamgirl [31]

Answer:

N≡N bond

Explanation:

Bond energy (bond enthalpy) is a measure of the bond strength in the bond. It is defined as average value of bond dissociation energies in the gas-phase for all the bonds having same type with in same chemical species.

<u>The greater the bond energy, the greater is the amount of energy required to break the bond, the more stable is the bond.</u>

Thus, among the following bonds:

O=O 498 kJ/mol

N≡N 946 kJ/mol

C=C 614 kJ/mol

C=O 745 kJ/mol

C≡C 839 kJ/mol

<u>The greatest bond energy is of N≡N 946 kJ/mol and thats why it is the most stable.</u>

A city located on the coast of North America has warmer winters and cooler summers than a city at the same elevation and latitud
Vesna [10]

I don't like any of those choices. But if you absolutely have to pick your answer
from this list, then it has to be 'D'.

The ocean is an enormous storage vessel for heat.  It gets heat from the air in
the Summer ... which somewhat cools places near the coast ... and it releases
heat into the air during the Winter ... which warms places near the coast.

So I guess it's true that ocean surfaces change temperature more slowly than
land surfaces do, and they influence the land nearby in the process. But this
ignores the reason for the slow changes in ocean surface temperature. It's a
lot like saying that the loud noise produced by a race car is the result of the
car's ability to appear in a far different location after a short time.
