Calcula el peso de un rover que será mandado a un planeta (=12 ⁄^2 ) fuera de nuestro Sistema Solar. Su masa es de 2,451 kg, su densidad es de 786 ⁄^3 y sus dimensiones son 4 m de ancho, 3.5 m de altura y 6 m de largo.

M1 = 2.8 kg, m2 = 6.72 kg, m3 = 11.2 kg, byas in .is ,is .toof m3 it 0.91 m. (in m/s)

Three resistors are connected in series across a 15-v power supply. if the potential drops across resistors 1 and 2 are 4.1 volts and 3.1 volts, what is the exact potential drop (in volts) across resistor 3?

The horizontal blue line through the middle of the lens is called the optical axis. as the lamp is moved above or below the axis, keeping the horizontal distance to the center of the lens constant, how does the horizontal distance from the lens to the image change?
