Planet with 1/2 the gravitational force as the earth. the effect of the mass and weight of the space probe is described below.
Explanation:
- At an altitude of 2642 km (approx. 1641 miles) above the Earth's surface, the gravitational acceleration will be 4.89m/s^2, which is half of 9.78 m/s^2 (the gravity at the surface).
- When the distance between the 2 objects is halved, the gravitational force between the 2 objects is doubled. when the distance between the 2 objects is doubled then the gravitational force doubles.
- Yes, a space probe that weighs 1000 pounds (excluding fuel) sitting in its launch vehicle on the launch pad will weigh much more from launch until the rocket's engines shut off. At that point it will become weightless. It becomes weightless because it's in free fall, even though it is still heading away from the Earth.
- In space without gravity pulling down on them, Astronauts are essentially weightless. It is important to explore the difference between mass and weight. ... However, if we went from Earth to Mars, our weight would change because Mars has less gravity than Earth. Gravity is a force pulling matter together.
I believe the correct answer from the choices listed above is option D. Based on the time scale, it would be that <span>the atmosphere was formed after microscopic life appeared on Earth that is the correct inference. It is very clear in the picture as the microorganisms appear before the atmosphere. Hope this answers the question. </span>
Answer: Primary Consumers (eat producers) The arrows in a food chain show the flow of energy, from the sun or hydrothermal vent to a top predator. As the energy flows from organism to organism, energy is lost at each step. A network of many food chains is called a food web.
Answer:
Most like a police officer. Because the cell membrane allows things in and out of the cell, as for a police officer in and out of a crime scene
hope it helps :)
