A (shortening the conductor)
Since resistance = (resistivity × length) / cross sectional area, decreasing length decreases resistance
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.

Answer:
Gravity
Explanation:
Gravity pulls things down to earth and it is a force
Answer:
The total power radiated by the sun is 3.71×10^26W
Explanation:
The Earth is spherical in shape
Therefore, Area = 4πr^2 = 4×3.143×(1.489×10^11)^2 = 2.79×10^23m^2
Power radiated by the Sun = solar radiation on Earth × Area = 1330W/m^2 × 2.79×10^23m^2 = 3.71×10^26W
Answer: The blind spot behind a vehicle is one of the most common causes of collisions while backing up.
Explanation:A blind spot in a vehicle is an area around the vehicle that cannot be directly observed by the driver while at the controls and this can be alleviated by the use of adjustable mirrors.
