A ball is moving at a speed of 6.70 m/s. If the kinetic energy of the ball is 3.10 J, what is the mass of the ball?

Anni [7]

Answer:

Explanation:

The mass of the ball can be found by using the formula

$m = \frac{2k}{ {v}^{2} } \\$

v is the velocity

k is the kinetic energy

From the question we have

$m = \frac{2(3.10)}{ {6.70}^{2} } = \frac{6.20}{44.89} \\ = 0.138115...$

We have the final answer as

Hope this helps you

The major anatomic difference in autonomic reflex arcs is that there are two sensory afferents. True or False

swat32

Answer:

False

Explanation:

All organisms have involuntary and rapid muscle responses that develop in some risk situation, which are known as reflexes. Each reflex has an associated reflex arc, a circuit formed by a receiver, which corresponds to a sensitive organ; an afferent path; an integration center; an efferent pathway and an effector; components that bind each other through the synapse.

In mammals, the reflex arc is composed of:

- The receptors, which are nervous structures, which generally correspond to the dendrites of sensory neurons, which transform the energy of a stimulus into a nerve impulse, because they are able to detect specific stimuli, triggering one or more nerve impulses. It is possible to find receptors in the skin, in the sense organs, in the viscera, in the muscles and in the tendons.

- Afferent peripheral nerves, which are formed by axons that drive nerve impulses towards integration centers.

- The integration centers, which are usually the components of the central nervous system, that have association neurons, analyzing the information that the sensitive neurons bring, and then develop a response.

- The efferent peripheral nerves, which are composed of axons that drive nerve impulses from the center of integration to the muscles or glands.

- The effectors, which are those that make the response to the stimuli, being able to perform this response the smooth, cardiac muscle or a gland, when the reflexes are visceral; or striated muscle, when the responses are somatic.
