- If the cloud layer of Venus is so thick, how is it possible for any sunlight to reach the surface planet theTitan is a moon of Saturn. Titan has wind erosion features. Would you expect Titan to have an atmosphere?Astronomers solved this puzzle when they observed a rare transit of Venus in front of the Sun (Figure 5). What could they learn about the planet’s atmosphere from this photo?
- Why are Mercury and the Moon much more cratered than Earth? Explain how the number of craters indicates the age of a surface.Eventually, space telescopes have shown that Venus is shrouded by a very dense atmosphere (see Figure 6). To pierce through the dense clouds and study its surface, astronomers had to use radio imaging (see Figure 7). Venus’ atmosphere is transparent to radio waves. Research and explain briefly how, through radio imaging, Venus’ surface could be reconstructed.Why is Mars red?
- Out of the inner planets in the solar system (Mercury, Venus and Mar) which do you think is the most likely to be colonized? Explain why?Which of the following describes what happens when we burn fossil fuels to produce energy? Fossil fuels release water and air into the atmosphere. A decrease in the overall temperature of the planet. A marked rise in the overall temperature of the planet. Fossil fuels release greenhouse gases into the air.Numerous surface features on Venus can be seen in Earth- based images made in the ultraviolet part of the spectrum. (T/F)
- Who knows why Mercury and the Moon have so many more impact craters than our planet. In what way does a surface's number of craters reflect its age?A perfectly elastic collision between two colliding objects of masses m₁ and m₂ is a collision that conserves both the quantity known as the total linear momentum and the quantity known as the total kinetic energy. For a perfectly elastic collision between mass m₁ moving at speed v₁; and mass m₂ moving at speed v2; prior to the collision, the conservation of total linear momentum is expressed as: m₁v₁i + m₂v₂i = m₁v₁f + m2 V2 f and the conservation of total kinetic energy is expressed as: 1 1 1 m₁(v₁i)² + ½ m2(v2;)² = = m₁(v₁ƒ)² + 21/1m2 (v21) ² 2 where Vif and V2f are the speeds of the masses, respectively, after the collision event. Part (a) Determine vif and V2f in terms of m₁, 22, Vli, V2i. Part (b) If m₁ = m₂ and v₁i = 5 [m/s] and mass 2 is initially at rest (i.e., a stationary target), find the direction and the speed of each mass after the collision. Part (c) If m₁ = m2, v₁i = 5 [m/s] and v2i = -5 [m/s] so that the two masses are initially moving toward each other with equal…
