Some stoves use the heat produced by current flowing through a conductor. if the heating element (conductor) has a resistance of 30 ohms, how long will the burner have to work to heat 500 g of 30°c water up to its boiling point? the specific heat of water is 4.19 x 103 j/kg·°c, and the household voltage is (120v).

Aperson gives a shopping cart an initial push along a horizontal floor to get it moving, and then lets go. the cart travels forward along the floor, gradually slowing as it moves. consider the horizontal force(s) on the cart while it is moving forward and slowing. which of the following statements is correct? (a) both a forward and a backward force are acting on the cart, but the forward force is larger. (b) only a forward force is acting which diminishes with time. (c) both a forward and a backward force are acting on the cart, but the backward force is larger. (d) only a backward force is acting, no forward force.
