Which is the most likely a reason why? A tobacco company funded Amelia to run experiments and publish a paper. She spent a year

completing several experiments to find a way to process tobacco leaves that would be better for health. Amelia conducted controlled experiments, and her results were the same each time. When scientists began conducting peer review, several of them were concerned that the results would be biased. O Her funding was from a source that could profit from the results. O She did not carry out the experiments for the minimum of 5 years. Most scientists do not conduct research on tobacco products. O Her results should have shown variation in the outcome.​

Sergeeva-Olga [200]

Ion

<u>Explanation:</u>

At the synaptic terminal, voltage-gated ion channels open, thereby stimulating the synaptic vesicles to release the neurotransmitters by exocytosis.

These ion channels are the signaling molecules in neurons. They are the transmembrane proteins that form ion channels. The membrane potential changes the conformation of the channel proteins that regulates their opening and closing. These channels play an important role in neurotransmitter release in presynaptic nerve endings.

For example - Ca²⁺ gated ion channel.

What is the constant snell’s law
Marat540 [252]

Snell's law is defined as “The ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant, for the light of a given colour and for the given pair of media”.

An average-sized asteroid located 5.0 x 10^7 km from Earth with mass 2.0 x 10^13 kg is detected headed directly toward Earth wit
devlian [24]

Answer:

v_f = 11.35 km/s

Explanation:

Given data:

Earth mass = 5.972 \times 10^{24} kg

distance between earth and asteroid is 5.0\times 10^7 km

asteroid mass = 2 \times 10^{13} kg

speed of asteroid = 2 km/s

potential energy is U = - \frac{GM_e m}{R}

U =- \frac{ 6.67 \times 10^{-11} \times 5.972 \times 10^{24} 2 \times 10^{13}}{5.0 \times 10^{10}}

U = -0.0159 \times 10^{19} J

Kinetic energy = \frac{1}{2} mv^2 = \frac{1}{2} \times 2\times 10^{13} \times (2\times 10^3)^2 = 4 \times 10^[19} J

Final potential energy of asteroid is

U_f = potential energy is U = - \frac{GM_e m}{R}

=- \frac{ 6.67 \times 10^{-11} \times 5.972 \times 10^{24} 2 \times 10^{13}}{6.371 \times 10^6}

U_f = -125\times 10^{19} J

from conservation of energy principle

U + K = U_f + K_f

solving for K_f

K_f = U +K - U_F

k_f = Kinetic energy = \frac{1}{2} mv_f^2

v_f = \sqrt{\frac{2(U +K - U_F)}{m}}

v_f = \sqrt{\frac{2\times (-0.0159 + 4+125) \times 10^{19}}{2\times 10^{13}}

v_f = 11.35 km/s

How does air resistance affect the acceleration of falling objects?
BlackZzzverrR [31]
Air resistance opposes the motion of falling objects. Dense air prefers to stay at low heights. More dense the air is, more air resistance it produces. Hence acceleration of falling objects decreases. Hope this helps!
