What are the magnitude and direction of the acceleration of an electron at a point where the electric field has magnitude 6100 n
Hoochie [10]

Force on electron due to electric field is given by

F = eE

F = 1.6 * 10^{-19}* 6100

F = 9.76 * 10^{-16} N

now the acceleration is given by

a = \frac{F}{m}

a = \frac{9.76 * 10^{-16}}{9.1 * 10^{-31}}

a = 1.07 * 10^{15} m/s^2

so above is the magnitude of acceleration and its direction is opposite to field as electron is negatively charged so direction is towards SOUTH

Lemon trees receiving the most water produced the most lemons. What is the independent variable, the dependent variable, and the
Veseljchak [2.6K]
The lemon trees will always be the same so they are the constants. The independent variable is the water amount because it is changing. The dependent variable is the amount of lemons because it is the variable being tested. (If we change the amount of water how many lemons will be produced?)

Which of the following statements about neurons are NOT true?
emmasim [6.3K]

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 should you approach a dock when the wind or current is pushing you away from the dock?
erastova [34]

Answer:

If the wind is offshore (blowing away from the dock), one should carefully approach the dock at a 20 to 30 degree angle. A bow line is then passed ashore and secured. In boats having an outboard, or inboard/outboard engine, the engine is turned towards the dock and put in reverse. This invariably will bring the stern into the dock.
