Trees. Every time the wind blows there is a wave of motion which is movement

Answer:

The wavelike motion usually can be described by the equation:

X(y,t) = Acos(kx - wt) + Bsin(kx - wt), so wavelike motion is usually a periodic motion.

Where k is the wavenumber and w is the frequency.

You can see a wavelike motion in trees when the wind moves them and the branches start to move in oscillatory motion.

Another example of wave motion can be some fishes, that use wavelike motion to impulse in the water.

Another example can be the Vipera ammodytes that move in a wavelike motion, with the objective of increasing its speed and agility in the sand.

Over [174]

The protons and electrons are held in place on the x axis.
The proton is at x = -d and the electron is at x = +d. They are released at the same time and the only force that affects movement is the electrostatic force that is applied on both subatomic particles. According to Newton's third law, the force Fpe exerted on protons by the electron is opposite in magnitude and direction to the force Fep exerted on the electron by the proton. That is, Fpe = - Fep. According to Newton's second law, this equation can be written as
Mp * ap = -Me * ae
where Mp and Me are the masses, and ap and ae are the accelerations of the proton and the electron, respectively. Since the mass of the electron is much smaller than the mass of the proton, in order for the equation above to hold, the acceleration of the electron at that moment must be considerably larger than the acceleration of the proton at that moment. Since electrons have much greater acceleration than protons, they achieve a faster rate than protons and therefore first reach the origin.

Movement of a molecule against its concentration gradient can occur through Select one or more: a. facilitated diffusion b. pass

uranmaximum [27]

Answer:

The answer to your question is:

Explanation:

There are two kinds of cell transport passive transportation and active transportation.

Passive transportation does not need energy because molecules move from higher concentration to lower concentration.

Active transportation needs energy because molecules moves against concentration.

a. facilitated diffusion It's an example of passive transportation so this answer is wrong.

b. passive transport Molecules move in favor of concentration so this answer is wrong.

c. osmosis is another example of passive transport so this answer is wrong.

d. simple diffusion it's another example of passive transport, so it's wrong this answer.

e. active transport this is the right answer.

When making a turn, do not have the steering wheel turned in the direction of the turn before beginning the turning maneuver.a)

RideAnS [48]

Answer:

a) True.

Explanation:

If you turn the wheel in the direction of the turn before beginning the turning maneuver then it's possible that there might be not enough space available for turning and also if you are waiting for the traffic to get clear with rear ended then it will get pushed forward onto the coming traffic.
