A planet's rotation determines the length of its day and its revolution determines the length of its year. A day on Earth is 24 hours and a year on Earth is 365 days. In contrast to Earth, a day on Venus is longer than a year on Venus. Which is the best reason for why this is so?

Assume you measured the mass of the cart to be (500 ± 1) g and the mass of the additional mass you put on the cart to be (500 ± 1) g as well. since the scale you are using in the lab cannot measure objects heavier than 600g you will have to sum up individual pieces and propagate the error. so what would be the mass and the standard error of the cart and the mass

Which changes would result in a decrease in the gravitational force btween two objects? check all that apply

According to newton’s law of universal gravitation, which statements are true? as we move to higher altitudes, the force of gravity on us decreases. as we move to higher altitudes, the force of gravity on us increases. as we gain mass, the force of gravity on us decreases. as we gain mass, the force of gravity on us increases. as we move faster, the force of gravity on us increases.
