<span>Answer: A) They are isotopes of nitrogen and they contain the same number of protons and electrons but each contains a different number of neutrons - 7 and 8 respectively.

Isotopes are atoms of a chemical element whose nucleus has the same atomic number, Z, but different atomic mass, A. The atomic number corresponds to the number of protons in the atom, therefore the isotopes of an element contain the same number of protons and electrons (atoms have to be neutral particles). The difference in atomic masses arises from the difference in the number of neutrons in the atomic nucleus.

Use this free body diagram to help you find the magnitude of the force F2 needed to keep this block in static equilibrium. WILL
oksian1 [2.3K]
Static equilibrium means that all forces are equal, so make this easiest you want to break F1 into it's horizontal and vertical components. As there are no other forces acting in the horizontal, we know the horizontal component of F1 is 40N. This allows the vertical component to be found using pythagorus theorem. After finding the vertical and horizontal components, you just have to add the vertical components to find the difference between the up and down.

When 1,250^3/4 is written in simplest radical form, which value remains under the radical?
GaryK [48]

Answer:

125\sqrt[4]{8}

Explanation:

A number of the form

a^{\frac{m}{n}}

can be re-written in the radical form as follows:

\sqrt[n]{a^m}

In this problem, we have:

a = 1,250

m = 3

n = 4

So, if we apply the formula, we get

1,250^{\frac{3}{4}}=\sqrt[4]{(1,250)^3}

Then, we can rewrite 1250 as

1250 = 2\cdot 5^4

So we can rewrite the expression as

=\sqrt[4]{(2\cdot 5^4)^3}=5^3 \sqrt[4]{2^3}=125\sqrt[4]{8}

Strong winds causing a vehicle to lose all control is called
mixer [17]
The answer to this question is "Buffeting". This is an unusual strong wind condition that resulted in the loss of vehicle control. This condition occurs in roads and bridges, across and along mountains that affected vehicles control. The drivers must be alert and put their full attention to overcome this condition.

What missions have been sent to explore Venus and what did they discover
faust18 [17]

Answer:

See below

Explanation:

  • Venus Express (2005 - 14)
  • Galileo (1989 - 90): As it flew by Venus on its way to Jupiter, it collected measurements of charged particles, dust and magnetism, infrared and ultraviolet spectral observation, data for infrared lower - atmosphere maps, and 81 camera images
  • Magellan (1989 - 90)
  • Vega 1 (1984 - 85)
  • Vega 2 (1984 - 85)
  • Venera 4 (1964): Atmosphere made up of entirely carbon dioxide, found that temperatures ranged from 40 degrees Celsius high up in the atmosphere to 280 degrees Celsius closer to the surface, and pressures ranged 15 to 22 atmospheres
  • Venera 6 (1969)
  • Venera 7 (1970): Became first spacecraft to return data from another planet and reported surface temperature of 475 degrees Celsius and atmospheric pressure 90 times greater than Earth's
  • Venera 8 (1972)
  • Venera 9 (1975)
  • Venera 10 (1975): Transmitted images from the surface
  • Venera 11 (1978): Sent back evidence of thunder and lightning as well as presence of carbon monoxide in lower altitude
  • Venera 12 (1978)
  • Venera 13 (1981 - 82): Returned first color images and found out the pressure was  84 times the pressure at sea level on Earth and the temperature was 457 degrees Celsius, before succumbing to them
  • Venera 14 (1981 - 82): Sent back images of Venus
  • Venera 15 (1983): Created radar map of Venus with Venera 16
  • Venera 16 (1983)
  • Pioneer Venus 1 (1978): Radar mapped nearly the entire planet, resolving features as small as 80 kilometers
  • Pioneer Venus 2 (1978): Consisted of 4 separate atmospheric probes
  • Mariner 2 (1962): Flyby attempt discovered ground temperatures as high as 428 degrees Celsius, but detected no water vapor or evidence of a magnetic field around planet
  • Mariner 5 (1967): During flyby, measured surface temperature of 267 degrees Celsius
  • Mariner 10 (1973 - 74): Took first ultraviolet images of Venus on way to Mercury
  • Akatsuki/Venus Climate Orbiter (2010 - today)

These are just some of the successful attempts by probes at or near Venus.
