Yes that would be true

Answer:

True

Explanation:

Nitrogen has five valence electrons, therefore, it needs three more valence electrons to complete its octet. In a diatomic molecule of Nitrogen, each atom shares three electrons to the bond, that is, three pairs of electrons are shared between the two atoms. This is called a triple bond, which is a covalent bond.

a bird flies at a speed of 15 m/s for 10s, 20 m/s for 20s, and 30 m/s for 15s. what is the birds average speed
gtnhenbr [62]

Average speed = (total distance) / (total time)

First segment:

15 m/s for 10 sec;  distance covered = (15 x 10) = 150 m

Second segment:

20 m/s for 20 sec; distance covered = (20 x 20) = 400 m

Third segment:

30 m/s for 15 sec; distrance covered = (30 x 15) = 450 m

Total time = (10s + 20s + 15s) = 45 sec

Total distance = (150m + 400m + 450m) = 1,000 m (1 km)

<em>Average speed</em> = (1,000 m) / (45 sec) = <em>22.22 m/s</em>

How large an expansion gap should be left between steel railroad rails if they may reach a maximum temperature 30.0°C greater th
irina [24]

Answer:

<em>1.2 cm</em>

Explanation:

<u>Thermal Expansion</u>

It's the tendency that materials have to change its size and/or shape under changes of temperature. It can be in one (linear), two (surface) or three (volume) dimensions.

The formula to compute the expansion of a material under a change of temperature from T_o to T_f is given by.

\Delta L=L_o.\alpha .(T_f-T_o)

Where Lo is the initial length and \alpha is the linear temperature expansion coefficient, which value is specific for each material. The data provided in the problem is as follows:

L_o=30\ m,\ T_f-T_o=30^oC,\ \alpha=13\times 10^{-6}\ ^oC^{-1}

Computing the expansion we have

\Delta L=30\times 13\times 10^{-6}(30)=0.0117=1.17\ cm

The expansion gap should be approximately 1.2 cm

A net force of 50 N causes a mass to accelerate at a rate of 6.8 m/s2. Determine the mass. ​
Taya2010 [7]
  • Force=50N
  • Acceleration=6.8m/s^2

\\ \sf\longmapsto F=ma

\\ \sf\longmapsto m=\dfrac{F}{a}

\\ \sf\longmapsto m=\dfrac{50}{6.8}

\\ \sf\longmapsto m=7.3kg
