Planet X has five times the diameter andfour times the mass of the earth. What is the ratio gX : ge of gravitational acceleration at the surface of planet X to the gravitational acceleration at the surface of the Earth? [Quest expects the answer in decimal form, like 0.25. It cannot understand an input like 1/4.

You have a resistor and a capacitor of unknown values. first, you charge the capacitor and discharge it through the resistor. by monitoring the capacitor voltage on an oscilloscope, you see that the voltage decays to half its initial value in 2.70 miss . you then use the resistor and capacitor to make a low-pass filter. what is the crossover frequency fc?

If anyonee has done the momentum lab practical in physics can you give me the answers i am s lostt rnn : (

Aparticle initially located at the origin has an acceleration of = 2.00ĵ m/s2 and an initial velocity of i = 8.00î m/s. find (a) the vector position of the particle at any time t (where t is measured in seconds), (b) the velocity of the particle at any time t, (c) the position of the particle at t = 7.00 s, and (d) the speed of the particle at t = 7.00
