Answer:
The slope of the graph is what you need. That tells you the speed not the velocity. In order to find the velocity you would also need to know the direction of the motion.
Answer:
13.4 x 10 raise to power -19 C
Explanation:
. The distance moved by a charge in the direction of a uniform electric field is d= 1.8 cm =0.018 m
. The uniform electric field is E = 214 N/M
, The decrease in electrical potential energy is
d(P.E) = 51.63 x 10 raise to power -19 J
Let the magnitude of the charge of the moving particle be q
which is given by the equation
d(P.E) =qEd
51.63 x 10 power -19 = q(214)(0.018)
51.63 x 10 power -19 =3.852q
by making q the formular,
q = 13.4 x 10 power -19 C

It really depends on how far or close the planet is from the sun
A. True. Matter requires energy to move and change.
B. False. Energy CAN change from one type to another. (Like changing the chemical energy in gasoline to kinetic energy of a moving car.)
C. False. Energy need not remain where it is created. (Like generating it in an electric power station and shipping it to your house to run your hair dryer.)
D. False. It IS possible to store energy for later use. (Like in a battery.)
