Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe. The earliest roots of science can be traced to Ancient Egypt and Mesopotamia in around 3000 to 1200 BCE.
It increases the precipitation in North America.
Answer:
Lens and the virtual image was the image distance. Error was made when measuring the distances and determining values that were reasonable for focal length, so this error was accounted for when calculating the focal length by adding or subtracting uncertainties from the values.Plane mirrors, convex mirrors, and diverging lenses can never produce a real image. A concave mirror and a converging lens will only produce a real image if the object is located beyond the focal point (i.e., more than one focal length away). 5.
Answer:
F = 96.11 N
friction force =33.48 N
Explanation:
given,
mass of block M = 7.50 kg
acceleration = 3 m/s²
µ s = 0.443 and µ k = 0.312
angle with the horizontal = 25°
the component of force along the incline is F cos theta
normal reaction ,
N = 66.68+ .423 F
for the mass
0.906 F - 0.132 F - 31.09 - 20.8 = 22.5
0.774F = 74.39
F = 96.11 N
normal force ,
N = 66.68 + .423×96.11
=107.33 N
friction force = .312 × N
= 0.312× 107.33
friction force =33.48 N
True
Mars' atmosphere is over 100 times thinner than Earth's and is primarily composed of carbon dioxide, nitrogen and argon gases. Oxygized dust particles kicked up from the Martian surface fill the atmosphere turning Mars' skies a rusty tan color, according to NASA(opens in new tab).
Water exists on Mars but the atmosphere is too thin for it to last long on the surface in a liquid state. Instead, water on Mars is found below the surface of the polar regions as water-ice and also as seasonal briny water flows down hillsides and crater walls.
Despite Mars' thin atmosphere, the Red Planet still exhibits a dynamic climate and extreme weather events including impressive dust storms and even snow! But Mars hasn't always been this way. NASA's MAVEN mission scientists reported that Mars once had a thick atmosphere(opens in new tab) that could have supported surface liquid water on the surface for extended periods of time.
What is mars?
Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System, being larger than only Mercury. In the English language, Mars is named for the Roman god of war. Mars is a terrestrial planet with a thin atmosphere, and has a crust primarily composed of elements similar to Earth's crust, as well as a core made of iron and nickel. Mars has surface features such as impact craters, valleys, dunes, and polar ice caps. It has two small and irregularly shaped moons: Phobos and Deimos.
