An 85 kg object is moving at a constant speed of 15 m/s in a circular path, which has a radius of 20 meters. what centripetal force is exerted on the body ? a. 63.75 nb. 765.00 nc. 956.25 nd. 42.50 n

The answer is : 956.25 N Fc = Centripetal Force, m = mass, V i= velocity and r is radius Fc = [m × (V)²] ÷ r Fc = [85 kg × (15 m/s)²] ÷ 20 m Fc = [85 kg x 225 m²/s²] ÷ 20 m Fc = 19,125 kg•m²/s² ÷ 20 m Fc = 956.25 kg•m/s² or 956.25 N

hi~~

i would say that hybridization occurs frequently in nature, because there are many types of hybrids that have occurred naturally, such as the mule (male donkey + female horse)

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands
