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.

A student launches a small 0.5 kg rocket with an initial speed of 30 m/s at an angle of 60°. Approximately how much time will th

Elena L [17]

Answer:

$t=5.30s$

Explanation:

The high reached by a proyectile in an uniformly accelerated motion is given by:

$y=v_{0y}t-\frac{gt^2}{2}$

The time that the rocket spends in the air is obtained for y = 0, since this is the time that the rocket travels before touching the ground. Recall that $v_{0y}=v_0sin\theta$ . Solving for t:

$0=(v_0sin\theta) t-\frac{gt^2}{2}\\\frac{gt}{2}=v_0sin\theta\\t=\frac{2v_0sin\theta}{g}\\t=\frac{2(30\frac{m}{s})sin(60^\circ)}{9.8\frac{m}{s^2}}\\t=5.30s$

Two resistors, A and B, are connected in a series circuit with a battery. The resistance of A is twice that of B. Which resistor

IgorC [24]

Answer:

A dissipates more power.

Explanation:

In a series circuit, the current is the same at any point in it.
The power dissipated in any resistor follows Joule's law, as follows:

$P = I^{2} * R$

So, for a given current, the power is directly proportional to the resistance of the resistor.
In this case, as resistor A has twice the resistance of resistor B, A dissipates twice more power than B.

Answer:

Explanation:

1.) The reaction is at dynamic equilibrium.

A: Nitrogen and hydrogen combine at the same rate that ammonia breaks down.

2.) Which statement about the reaction is necessarily correct?

A: Both calcium carbonate and sodium carbonate are being produced.

3.) Both calcium carbonate and sodium carbonate are being produced.

A: The reaction is reversible.

4.) What is the fastest motion that can be measured in any frame of reference?

A: 300,000 km/s

5.) Two people are on a train that is moving at 10 m/s north. They are walking 1 m/s south relative to the train. Relative to the ground, their motion is 9 m/s north.

Why are we able to use these motions to describe the motion relative to the ground?

A: The people are moving much slower than the speed of light so the ground acts as a frame of reference.
