The Canadian microsatellite MOST (Microvariability and Oscillations of Stars) has a mass of just 52 kg. It travels in an almost circular orbit at an average altitude of 820 km above Earth’s surface. a) Calculate the gravitational force between Earth and the MOST satellite...

How does the weight of a Mars lander change as it travels from Earth to Mars? Does the weight ever equal zero? Does the mass of the lander change? Explain your answer. (Hint: restrict your analysis to a system consisting of Earth, Mars and lander.)

Math {ASAP}
put it like this 100% is 20 then 10% is x now you just have to cross multiply so u get ..... 100x=(20) * (10) therefore, x=(20)*(10)/100 x=2

physics
in 2005, the space probe Deep Impact launched a 30 kg projectile into Comet Tempel 1. Observing the collision helped scientists learn about the comet’s characteristics. The come is estimated to have a mass of 9.0 x 1013 kg. a. Assuming the estimated mass of the comet at t...

physics
he universal law of gravitation describes the force of gravity between two bodies. What does it say about the strength of the gravitational field? How does the size of the object affect the use of the gravitational field equation?

How is it possible for an object to obtain a larger impulse from a smaller force than from a larger force? i have no clue how this can happen .....it seems impossible ..

physics
If you throw a ball against a wall, which of the three impulses is the greatest: throw, bounce, or catch? I think it would be the bounce because the momentum of the ball is highest when it hits the wall. and basically impulse is the change in momentum...am i correct ???.....if...

physics
A mass oscillates with a period of 2.8 s on the end of a spring that has a spring constant of 75 N/m. What is the magnitude of the mass?

physics
A tennis player smashes a serve so that the racquet is in contact with the ball for 0.055 s, giving it an impulse of 2.5 N ⋅ s. What average force was applied during this time? Assume that the vertical motion of the ball can be ignored. If the ball's mass is 0.0...
