Kinetic energy of any object = (1/2) (object's mass) (object's speed)²

Arrow's kinetic energy = (1/2) (0.217 kg) (100 m/s)² = 1,085 Joules

Pumpkin's kinetic energy = (1/2) (3.75 kg) (7.25 m/s)² = 98.5 Joules

== 1,085 Joules is more than 98.5 Joules.

==> <em>The arrow</em> has more kinetic energy than the pumpkin has.

Iron atoms have been detected in the sun's atmosphere, some with many of their electrons stripped away. What is the net electric
BaLLatris [955]

Answer:

2.88 × 10⁻¹⁸ C

Explanation:

The charge on a proton and electron are the same and it is = 1.6 × 10⁻¹⁹ C

The net charge electric charge of an iron atom = (number of proton × charge on a proton) + ( number of electron × charge on an electron ) = 26 (e) + 8 (-e) = 26 e - 8 e = 18 e = 18 ×  1.6 × 10⁻¹⁹ C = 2.88 × 10⁻¹⁸ C
