Kinetic energy = 0.5*M*V^2
Q7-
0.5*3*(2^2)= 6J
Q8a-
0.5*2*(2^2)= 4J
0.5*4*(3^2)=18J
the second ball has more kinetic energy.
Q8b-
at the max height, all the kinetic energy is converted to potential energy,
gravitational potential energy is = M*g*h
that theory would apply if you wanted to work out the maximum height achieved if the balls were thrown upward by rearranging. But, we are simply working out which ball will have more potential energy so:
First ball:
2kg*9.81(g)*10m = 196.2J
Second ball
4kg*9.81*10m= 392.4J
The second ball has more potential energy
Answer:
co-dominance
Explanation:
in co-dominance both parents are dominant
<span>main function of the circulatory system in multicellular organisms is to circulate blood and oxygen in our body .so the right option is
</span><span>A) to bring oxygen into the lung
</span>hope this helps
Answer:
a because there are colder temperature s in the winter months in the northern states
The shape of the Stegosaurus cranium allowed for extra jaw muscle mass than the alternative herbivores. This intended an extra green conversion of muscle energy into the pressure of the chew. The research indicates that Stegosaurus might be capable of foraging on huge sorts of flowers, which include ferns and cycads.
Stegosaurus ate gastroliths. Small stones that ground its favorite greens up in its belly. it's far believed to have eaten vegetation together with mosses, ferns, horsetails, cycads, and conifers or culmination.
The stegosaurus turned into such a cool dinosaur. It had neat plates and spikes covering its tail, again, and neck that made it appear very exclusive. however, it was additionally a plant-consuming device! It had a toothless beak for nipping low-mendacity vegetation like ferns, cycads, and pines.
The small blunt teeth show that Stegosaurus become an herbivore. It had a huge intestine to break down the plants it ate. Stegosaurus became maximum probably prey for the likes of Allosaurus, Torvosaurus, and perhaps even smaller meat eaters.
