A space probe in a low earth orbit is inserted into an elliptic transfer orbit to the planet Venus. Knowing that the mass of the sun is times the mass of the earth and assuming that the probe is subjected only to the gravitational attraction of the sun, determine the value of which defines the relative position of Venus with respect to the earth at the time the probe is inserted into the transfer orbit.

An object has a weight of 500 on earth what is the mass of this object

An astronaut in space cannot use a scale or balance to weigh objects because there is no gravity. but she does have devices to measure distance and time accurately. she knows her own mass is 77.4 kg , but she is unsure of the mass of a large gas canister in the airless rocket. when this canister is approaching her at 3.50 m/s , she pushes against it, which slows it down to 1.30 m/s (but does not reverse it) and gives her a speed of 2.60 m/s . what is the mass of the canister?

Why do some scientists and archeologists think that volta was not the first person to build a battery
