A book is sitting on a shelf that is 3.0 meters off the ground. Kinetic energy is found using the formula 1/2 times mass times s

peed. Potential energy is found by taking mass times g times height, with g as the constant, 9.8 m/s squared. What is needed to determine the mechanical energy used to move this book?

Which mystery primate is a biped? list the characteristics you choose to justify your answer
Vadim26 [7]

Primate B mystery primate is a biped.

The characteristics are:

  1. The vast majority of primates live in trees (Notable exceptions are humans and gorillas).
  2. The majority of primates have upright upper bodies and occasionally walk on two feet (Humans are erect and always exhibit bipedalism).
  3. All primates have smaller noses and matching olfactory brain regions (except Lemurs).
  4. Compared to other mammals, primates have enormous brains for their size. Stereoscopic vision, hand-eye coordination, and manual dexterity are all governed by the brain's enlarged regions.
  5. Considering the size of the animal, long gestations
  6. Primate sociality is rather high in general.
  7. The majority of primates are nocturnal.
  8. The highly enjoyable action of grooming is shared by all highly evolved primates, including humans.
<h3>Primate </h3>

Lemurs, lorises, tarsiers, monkeys, apes, and humans are all included in the biological order called primates. Class Mammalian of the phylum Vertebrate includes creatures with qualities that have evolved recently in the taxonomic classification of the animal kingdom. 19 subtaxa known as orders have been added to the Mammalia classification. Primates are one of such groups, which contains eutherian animals like monkeys and apes. As a result, during a period of 30 million years, new world and old world monkeys underwent different adaptive radiations and were reproductively isolated. The Oligocene epoch saw the evolution of prosimians. About 30 million years ago, all currently extant primates underwent evolution.

Diagnostic ultrasound of frequency 3.82 MHz is used to examine tumors in soft tissue. (a) What is the wavelength in air of such
maxonik [38]

Explanation:

It is given that,

Frequency of diagnostic ultrasound, f = 3.82 MHz = 3820 Hz

The speed of the sound in air, v = 343 m/s

(a) We need to find the wavelength in air of such a sound wave. Let it is given by λ₁

i.e. \lambda=\dfrac{v}{\nu}

\lambda_1=\dfrac{343\ m/s}{3820\ Hz}

\lambda_1=0.089\ m

(b) If the speed of sound in tissue is 1650 m/s .

\lambda_2=\dfrac{v}{\nu}

\lambda_2=\dfrac{1650\ m/s}{3820\ Hz}

\lambda_2=0.43\ m

Hence, this is the required solution.
