Answer:

Wave speed is related to wavelength, frequency, and period by the equation wave speed = frequency x wavelength.

Explanation:

I hope my answer helped <3 Have a nice day

The equation for the speed of the wave is v = λ × f. The speed of a wave depends on wavelength and frequency.

The rate at which a wave moves across a medium is referred to as its speed. It displays the speed at which the wave's disruption or energy spreads. The characteristics of the medium a wave travels through affect its speed.

The equation for the wave's speed (v) for a mechanical wave, such as one moving via a string or a spring, is as follows:

v = λ × f

Here:

v = speed of the wave

λ  = wavelength of the wave

f = frequency of the wave

Hence, the equation for the speed of the wave is v = λ × f. The speed of a wave depends on wavelength and frequency.

In the given four models of rockets, the rocket with the highest acceleration is rocket 2.

Acceleration is the rate of change of velocity with time. The acceleration of the rockets can also be determined from Newton's second law of motion with the applied force and mass of each rocket as shown below;

F = ma

where;

a = F/m

a = 120/4.25

a = 28.24 m/s²

a = 120/3.25

a = 36.92 m/s²

a = 120/5.5

a = 21.82 m/s²

a = 120/4.5

a = 26.7 m/s²

Thus, the rocket with the highest acceleration is rocket 2.

The maximum amount of kinetic energy the diver will have just before she hits the water will be the same as the gravitational potential energy before take-off. Maximum kinetic energy is also 7500Joules

Gravitational energy is the energy possessed by an object by virtue of its position.

It is expressed according to the formula:

GPE = mgh

m is the mass of the object

g is the acceleration due to gravity

h is the height

If a diver has Gravitational energy of 7500Joules before the diver jumps off, the maximum amount of kinetic energy the diver will have just before she hits the water will be the same as the gravitational potential energy before take-off.

The direction of the sum of vectors A and B is approximately 22.9 degrees north of east.

To find the direction of the sum of vectors A and B, we can use trigonometry to determine the angle with respect to the positive x-axis (east direction). The given vectors A and B have magnitudes and directions as follows:

Vector A: Magnitude = 9.66 m, Direction = East

Vector B: Magnitude = 12.0 m, Direction = Northwest (which is 45 degrees north of west)

To find the resultant vector's direction, we need to add the angles of the two vectors. The angle between the positive x-axis and vector A is 0 degrees (east direction), and the angle between the positive x-axis and vector B is 45 degrees (northwest direction). Therefore, the angle between vector A and the resultant vector is 0 degrees, and the angle between vector B and the resultant vector is 45 degrees.

To find the angle of the resultant vector with respect to the positive x-axis (east direction), we can use the tangent function:

Tan(Angle)= Opposite/Adjacent​ = Magnitude of Vector A/Magnitude of Vector B

Taking the inverse tangent (arctan) of both sides:

Angle = arctan (9.66/12.0)≈22.9 degrees

So, the direction of the sum of vectors A and B is approximately 22.9 degrees north of east.

Thee force constant can be obtained using the relation, K = F/e

According to Hooke's law, as long as the elastic limit is not exceeded, the extension is directly proportional to the force applied. In this case, the question is incomplete since the force applied is missing.

The answer is see the person above is correct They must lose enough other kinetic energy so that the attractions between them hold in place has been vibrate

Explanation:Got it correct

For a substance to change from a liquid to a solid, the particles must lose enough of their kinetic energy so that the attractions between them hold in place as they vibrate. Thus, the correct option is C.

Kinetic energy is the energy which an object has because of its motion. If we want to accelerate an object, then it is required to apply a certain amount of force. Applying a force requires us to perform work. After work has been done on the object, then the energy has been transferred to the object, and the object will be moving with a new constant speed and no acceleration.

To solve the problem, we have to decompose the two vectors along the two directions first:Vector A:- x component: Ax = +9.66 m- y compoment: Ay = 0 (the vector lies along the x-axis)Vector B:- x component: - y component: So now we can find the sum of the two vectors by adding the components along each axis:And the magnitude of the sum is given by Pythagorean theorem:

x(t)=voₓ.t = vo cos α.t

the greater the initial speed, the further the distance obtained

The horizontal distance traveled by a projectile (also known as the range of the projectile) is determined by the initial speed of the projectile, as well as other factors such as the angle at which it is launched and the gravitational acceleration acting on it.

A projectile is an object that is projected into the air and follows a parabolic path under the influence of gravity. Examples of projectiles include balls thrown or kicked in sports, bullets fired from guns, and rocks or other objects that are thrown or dropped.

To determine the effect of the initial speed on the horizontal distance traveled by a projectile, you can use the following formula:

[tex]Range = (Initial speed)^2 * sin(2 * Launch angle) / gravitational acceleration[/tex]

This formula shows that the range of a projectile is directly proportional to the initial speed of the projectile squared, and is also affected by the launch angle and gravitational acceleration.
