True. The length of time that it takes to complete one orbit around the Sun is directly related to the distance of the orbit from the Sun.
False. Not all planets have at least one moon. For example, Mercury and Venus have no moons, whereas Jupiter and Saturn have many moons.
false
False the light year is not a unit of time it is a unit of distance true.
It is false. The Earth's orbit is an ellipse (oval), although the distance only varies by about 3.4% from closest to farthest (147 million to 152 million kilometers).
true
False. Work is directly proportional to the distance applied. The amount of work done increases as the distance over which the force is applied increases.
False. The force of gravity is determined by the masses of the objects and the distance between them. It decreases as the distance between the objects increases.
That is false.
True. The strength of the electric field created by a charged particle is inversely proportional to the square of the distance from the particle. As the distance decreases, the electric field strength increases.
False. The outer planets are gas giants (although they have a solid core). The inner planets are 'rocky'.
False. Gravitational force is actually directly proportional to the masses of the two objects and inversely proportional to the square of the distance between them. This means that as the mass increases or the distance decreases, the gravitational force between the two objects will increase.
False. There is a limit to the rate of photosynthesis even as light intensity increases. Once the saturation point is reached, the rate of photosynthesis remains constant.
false
did Tycho Brahe came to the wrong conclusion about motions of the planets. true or false?
False. The wavelength of a wave is measured from crest to crest or trough to trough, representing the distance between two corresponding points on a wave cycle.
false
False.
