A stunt pilot of mass 49.0 kg who has been diving her airplane vertically pulls out of the dive by changing her course to a circle in a vertical plane. Part A If the plane's speed at the lowest point of the circle is 94.0 m/s , what is the minimum radius of the circle for the acceleration at this point not to exceed 4.00g ?

Determine the maximum r-value of the polar equation r =3+3 cos 0

Consider a hydrogen atom in the ground state. what is the energy of its electron? =e= jj now consider an excited‑state hydrogen atom. what is the energy of the electron in the =5n=5 level? =e5= j

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
