6 A student sets up a circuit containing three identical cells. Each cell has an e. mf. (electromotive
force) of 2.0V.
Fig. 8.1 shows the cells in series with a length of uniform metal wire connected between two
terminals Kand L, an ammeter and a resistor X.

Fig. 8.1
(a) State the total e. mf. of the three cells in series.
total e. m.f. =
[1]
(b) The ammeter reading is 0.25A.
(1) State the name of the unit in which electric charge is measured.
(11) Calculate the charge that flows through the circuit in twelve minutes.

Ogle–2013–blg–0723 is an exoplanet that is similar to earth in size and proximity to its star. this exoplanet has mass m=4.18×1024kg and radius r=5.66×106m. an astronaut whose weight on earth is w=735n lands on the planet. a. calculate m, the mass of the astronaut. b. calculate gp? , the acceleration due to gravity on the surface of ogle–2013–blg–0723. c. calculate wp? , the weight of the astronaut on the surface of ogle–2013–blg–0723. d. calculate v, the minimum velocity required to put an object into orbit above ogle–2013–blg–0723. e. calculate t, the time required to complete an orbit around ogle–2013–blg–0723.
