Determine the gravitational force of attraction between the Earth and the Sun given the mass of the earth is 6 x 10^24 kg, the m
Helga [31]

Answer:

35.57*10^21 N.

Explanation:

F = Gmm/r², where G is 6.67*10e-11 & r is distance.

F = 6.67*10^-11 * 6*10^24 *2*10^30 /(1.5*10^11)².

F = 35.57*10^21 newtons.

What is NOT a major factor affecting climate?
professor190 [17]

B Longitude

Explanation:

The line of longitude or longitude does not affects climates.

Climate is the weather condition over a place for a long period of time. It usually takes several years to delineate the climate of an area.

  •  Longitude is the distance on the earth surface that runs form east to west.
  • All lines of longitude are all great circles.
  • Latitude are lines from north to south on the earth surface. Only the equator is a great circle.
  • Latitude affects climate. In fact based on the division of lines of latitude on can predict climatic patterns on earth.
  • Proximity to water bodies also affects climatic condition because of the effect of land and sea breeze and other climatic factors.
  • Elevation affects climate a whole lot. Physiography of a place determines the weather to a very large extent.

If a motorcycle accelerates uniformly from rest at 5 m / s2, how long does it take for it to reach a speed of 20 m / s.
irina1246 [14]

Answer:

4 seconds

Explanation:

Given:

v₀ = 0 m/s

v = 20 m/s

a = 5 m/s²

Find: t

v = at + v₀

20 m/s = (5 m/s²) t + 0 m/s

t = 4 s
