16.
A balloon with a radius of 16 cm has an electric charge of 4.25 × 10–9 C.
a. Determine the electric field strength at a distance of 40.0 cm from the balloon’s centre.
E=kq/r^2 (8.99 x 10^9) (4.25 x 10^-9) / (0.40)^2
=1492.5N/C
b. A balloon with a radius of 14 cm and an electric charge of 3.75 × 10–9 C is brought within the electric field of the larger balloon so their centres are 40.0 cm apart. Determine the magnitude of the electric force exerted by this electric field on the smaller balloon.

answer: cesare beccaria developed the classical school of criminology with from philosopher jeremy bentham

explanation:

graph slopes whilst gas cools, then it is flat whilst conensation to liquid happens, the coolong liquid then graphs as a slope when it solidifies graph is flat

latent heat

grav forces affect all objects magnetic forces affect magnetic objects and electric currents

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
