Physics
1 answer:
emmasim [6.3K]3 years ago
5 0

Answer:

The correct answers to the question are

The following statements about neurons are NOT true

A. The resting membrane potential is generally in the range of -40 mv to -75 mv.

C. Neurons repolarize by opening chloride channels on the membrane.

D. An action potential can occur when the neuron's sodium gates open.

Explanation:

A. The resting membrane potential is generally in the range of -40 mv to -75 mv.

Not true the resting potential for neurons range from -70 to -80 mv

B. Maintaining resting membrane potential requires the use of energy from ATP True

The potential of the membrane arises from the splitting of potassium ions from the intracellular anions by agents powered by ATP

C. Neurons repolarize by opening chloride channels on the membrane

Not True

Repolarization occurs by the outward transit of the positively charged K⁺ from the cell

D. An action potential can occur when the neuron's sodium gates open.

Not True

An action potential takes place once the neuron transmits information along an axon. An action potential results when different ions pass through the membrane of the neuron

How is force defined?​
ArbitrLikvidat [17]

Answer:

In physics, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity (which includes to begin moving from a state of rest), i.e., to accelerate. Force can also be described intuitively as a push or a pull.

An open cart is rolling to the left on a horizontal surface. A package slides down a chute and lands in the cart. Which quantity
Marat540 [252]

Answer: the horizontal component of total momentum

Explanation:

Since the open cart is rolling to the left on the horizontal surface, the quantity that has the same value just before and just after the package lands in the cart is the horizontal component of total momentum.

Momentum, is the product of the mass of a particle and the velocity of the particle. The change of momentum depends on the force which acts on it. The addition of the the individual momenta is the total momentum.

A​ heavy-duty shock absorber is compressed 4 cm from its equilibrium position by a mass of 700nbspkg. How much work is required
tia_tia [17]

Answer:

Explanation:

A mass of 700 kg will exert a force of

700 x 9.8

= 6860 N.

Amount of compression x = 4 cm

= 4 x 10⁻² m

Force constant K = force of compression / compression

= 6860 / 4 x 10⁻²

= 1715 x 10² Nm⁻¹.

Let us take compression of r at any moment

Restoring force by spring

= k r

Force required to compress = kr

Let it is compressed  by small length dr during which force will remain constant.

Work done

dW =  Force x displacement

= -kr -dr

= kr dr

Work done to compress by length d

for it r ranges from 0 to -d

Integrating on both sides

W  = \int\limits^{-4}_0 {kr} \, dr

= [ kr²/2]₀^-4

= 1/2 kX16X10⁻⁴

= .5 x 1715 x 10² x 16 x 10⁻⁴

= 137.20 J
