Could i please get some help with this, it would mean a lot. Thank you.

Question 1 11 2 In the figure provided a wire consists of two segments made from the same material but with different diameters. If the current in segment 1 is I, and the current in segment 2 is 2, which of the following is true about their current densities J, and J2 in the two segments? O J1 is less than J2 O J1 is greater than J2 O J1 is equal to J2Question 2 If the current in a wire is halved, how will this affect the mean time between collisions? O The mean time between collisions will be halved. O The mean time between collisions will remain unchanged. 0 The mean time between collisions will be doubled. Question 3 The circuit below has resistors R, = 26.3 9, R2: 7.30 0,33 = 5.90 R, and R4 = 4.90 9 connected to a battery wth potential AV: 49.5 V. What is the equivalent resistance of the circuit? C 16.5 (1 O 17.3 C! O 44.40 C) 8.39 (1 Question 4 R R When the switch s open in the circuit above, the battery drives a current / in the direction shown. How happens to the current / through the battery when the switch is closed? The current / will increase. O The current / will remain the same. O The current / will decrease.Question 1 Given the values of the capacitors below, what is the potential difference across capacitor C1? 01:4.10uF g = 5.20 pF (:3 = 7.50 pF : Question 2 For fun. you decide to build a circuit, but you have an unknown capacitor laying around. To measure it, you place it in series with a 5.00 uF capacitor you have and connect them to a 5.00 V battery. Using yourtrusty voltmeter, you measure 2.10 V across the unknown capacitor. What is its capacitance
