Brainiest if correct? I'd appreciate it SM :D
Answer: I believe it’s location D. Or whichever is the location of slow crystallization.
Explanation: Slow crystallization of magma forms granite. Hope this helps. :)
Answer: Actually three of them are. The ovaries, the uterus and fallopian tubes.
Answer: d
Explanation:
mass of truck mt, kinetic energy of truck Ekt(Kt), Vt -speed of truck
mass of car ma, kinetic enregy of car Ekc(Kc), Vc-speed of car
mass of truck mt=2*mc
speed of truck Vt=2*Vc
Compare Kinetic energy of truck with kinetic energy of car using equation to calculatation ;
Kinetic energy of car:
Kc=(mc*Vc²)/2
Kinetic energy for truck:
Kt=(mt*Vt²)/2
Kt=((2*mc*(2*Vc)²)/2
Kt=(2*mc*4*Vc²)/2
Kt=8*mc*Vc²/2
Compare Kinteic energy truck with Kinetic energy of car:
Kt/Kc
Kt/Kc=((8*mc*Vc²)/2)/((mc*Vc²)/2)
Kt/Kc=8
Explanation:
the efficiency of a machine can be increased by reducing the friction
