Erica is competing in the shot put event at a track meet. she hurls a shot with a mass of 4 kilograms at a speed of 9 meters/second. the shot’s kinetic energy is joules.

We have: K.E. = mv² / 2

here, m = 4 Kg

v = 9 m/s

Substitute their values into the expression:

K.E. = (4)(9)² / 2

K.E. = (4)(81) / 2

K.E. = 324 / 2

K.E. = 162 Joules

In short, Your Answer would be 162 J

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.
