The first large herbivores and carnivores appeared during the Mesozoic Era, which is divided into three periods-- Triassic, Jurassic and Cretaceous. The herbivores and and carnivores increased in size during the Jurassic Period. And some of the largest dinosaurs emerged during this period as well.
Answer: 109.89 Nm
Explanation:
The maximum torque will be calculated as the force multiplied by the perpendicular distance. This will be:
Torque = force × perpendicular distance
torque = 333 × 0.33
= 109.89 Nm
The base of the pyramid has the producers and everything else above the base falls under the consumers category i.e the locusts,frogs and the snake. The grass is the producer, the locust is a consumer, the frog is a special type of omnivore, termed the "life-history omnivore" since they eat both plants and animals but at different times in their lives. In this case they are just omnivores and lastly, the snake is a carnivore.
Answer:
a) v = 1524.7 m/s
b) T = 8.47*10^-4 s
λ = 1.29 m
Explanation:
a) First, in order to calculate the speed of the sound wave, you take into account that the velocity is constant, then, you use the following formula:
d: distance traveled by the sound wave, which is twice the distance to the ocean bottom = 2*324 m = 648 m
t: time that sound wave takes to return to the sub = 0.425
hence, the speed of the sound wave is 1524.7 m/s
b) Next, with the value of the velocity of the wave you can calculate the wavelength of the wave, by using the following formula:
f: frequency = 1.18*10^3 Hz
And the period is:
hence, the wavelength and period of the sound wave is, respectively, 1.29m and 8.47*10^-4 s
