The all-new iPhone Xs has a 2716mAh Li-ion battery. After a full charge, Sam used it for exactly a full day without recharging, leaving 15% battery in the phone. If the voltage of the battery is 3.8V, estimate (1) the average electric current (in Amperes), (2) the total amount of electric energy (in Joules), and (3) the average power (in Watts) that Sam’s iPhone Xs consumed during that day. This battery only has a mass of about 50 grams. As a comparison, search online and then estimate the amount of energy released by the explosion of 50 grams of TNT

Kristen recently considered several different Iphone models when buying a new phone, including the XR, XS and 11. Kristen purchased a Iphone XR. The same day she took it out of the box, she read an article that the phone doesn’t allow for 3D pictures to be taken and posted to social media. She began to regret her decision to purchase the XR and thought perhaps she should have chosen a different model. Kristen was most likely experiencing

An isolated parallel-plate capacitor (not connected to a battery) has a charge of Q = 2.4×10−5C. The separation between the plates initially is d = 1.2 mm, and for this separation the capacitance is 3.1×10−11F. Calculate the work that must be done to pull the plates apart until their separation becomes 8.3 mm, if the charge on the plates remains constant. The capacitor plates are in a vacuum. Express your answer using two significant figures
