Ali menginduksikan sebuah batang besi bermuatan +7,2 x 10-7 C dengan logam sampai batang besi tersebut menjadi netral. Oleh karena Ali lupa memakai sandal karet sebagai isolator, maka logam hasil induksinya kehilangan muatannya dengan kecepatan 10-6 C/s. Waktu kembalinya batang logam tersebut menjadi netral karena elektron tambahannya adalah A. 1,2 Menit

B. 5,5 Menit

C. 1 Menit

D. 2,4 Menit

What is the electric force acting between two charges of -0.0045 c and -0.0025 c that are 0.0060 m apart? use fe=kq1q2/r^2 and k = 9.00 x 10^9 n*m^2/c^2 a. 1.7 x 10^7 n b. -1.7 x 10^7 n c. -2.8 x 10^9 n d. 2.8 x 10^9 n

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)

What conclusion can be made based on the temperature of soil when the light hits the soil at 0°, 45°, and 90° angles in section 2 of the experiment? did your results support your hypothesis? why or why not?
