Answer:
6.25 g/cm³
Explanation:
2 cm * 2 cm * 3 cm = 12 cm³ (volume)
75 g / 12 cm³ = 6.25 g/cm³
A. meteor which object is usually found passing through the earth's atmosphere are meteor
Answer:
Following are the responses to the given question:
Explanation:
The mass (mg) is downwards, the typical pressure is upward. This pushing force of is pushed forward by skater 3 on skater 2. (considered as rightward direction). The strength of the slater 2 in reply is the slater Skater three moves to the left.
Its push force imparted to the skateboarder 2 in relation those above forces The force on skater 2 by skater 1 is as a response, to a left. Skater 2's free body system is as follows:
Because plants have to use cyanobacteria during photosynthesis so they could not survive before the cyanobacteria started producing oxygen
Answer:
See explanation below
Explanation:
Recall that Weight is a Force that results from the action of a gravitational field on our body mass. Therefore if one changes locations to places where the acceleration of gravity is different, our weight can change although the mass of our body stays the same.
For example, going to a high mountain, where the acceleration of gravity is a little smaller than at sea level, will produce such change. Also, going to another planet with different gravitational field, or going to the Moon (where the acceleration of gravity is about 1/6 of that on Earth which therefore will reduce our weight without reducing our mass)
