Characteristics: Iron is a ductile, gray, relatively soft metal and is a moderately good conductor of heat and electricity. It is attracted by magnets and can be readily magnetized. The pure metal is chemically very reactive and rusts readily in moist air, forming red-brown oxides.

Which of the following possibilities will form a triangle? (1 point)
Tpy6a [65]

Answer:

Side = 10 cm, side = 5 cm, side = 6 cm

Explanation:

Triangle is made up of three line segment. Three line segment can form a triangle only when sum of two small line segment is more than the third line segment.

a. Side = 10 cm, side = 5 cm, side = 6 cm

5 cm + 6 cm  = 11 cm > 10cm

In the first option, the sum of two small sides is more than the third size, hence it will form a triangle.

Other options do not fulfil the same criteria, so they will not form a triangle.

Hence, the correct answer is "Side = 10 cm, side = 5 cm, side = 6 cm".

. If the fastest passenger aircraft can fly 0.45 km/s (1000 mph), how long would it take to reach the sun? The galactic center?
nadezda [96]

Answer:

The passenger aircraft would take 10.542 years to reach the Sun from the Earth.

The passenger aircraft would take 1.733\times 10^{10} years to reach the gallactic center.

Explanation:

The distance to the sun from the Earth is approximately equal to 1.496\times 10^{8}\,km, if the passenger travels at constant speed, then the time needed to reach the sun is calculated by the following kinematic formula:

\Delta t = \frac{s}{v} (1)

Where:

s - Travelled distance, measured in kilometers.

v - Speed of the passenger aircraft, measured in kilometers per second.

\Delta t - Travelling time, measured in seconds.

If we know that s = 1.496\times 10^{8}\,km and v = 0.45\,\frac{km}{s}, then the travelling time is:

\Delta t = \frac{1.496\times 10^{8}\,km}{0.45\,\frac{km}{h} }

\Delta t = 3.324\times 10^{8}\,s

\Delta t = 3847.736\,days

\Delta t = 10.542\,years

The passenger aircraft would take 10.542 years to reach the Sun from the Earth.

The distance between the Earth and the galactic center is approximately equal to 2.460\times 10^{17}\,km. If the passenger travels at constant speed and if we know that s = 2.460\times 10^{17}\,km and v = 0.45\,\frac{km}{s} , then the travelling time is:

\Delta t = \frac{2.460\times 10^{17}\,km}{0.45\,\frac{km}{s} }

\Delta t = 5.467\times 10^{17}\,s

\Delta t = 6.327\times 10^{12}\,days

\Delta t = 1.733\times 10^{10}\,years

The passenger aircraft would take 1.733\times 10^{10} years to reach the gallactic center.
