what property of light is responsible for the different colors we observe? different colors have different frequencies. the size of the photon determines the color. varying levels of intensity result in different colors. the speed of a light wave determines its color.

The vertical component of the tensions in each rope is 50 N.

Weight of traffic light = w = 100N

The angle at which the ropes are supported = θ = 30

After drawing Free Body Diagram,

The vertical component of tension in each rope =

= 2 X T X sinθ = w

= 100 = 2 X T X sin30

= T = 100 / ( 2 X sin30)

= T = 100 N

Now, tension on vertical component =  

= Tsin30

= 100 X 0.5

= 50 N

The momentum of the ostrich with mass 163 kg at velocity 14m/s would be 2282 kg·m/s

Momentum is characterized as the intensity of a body's motion. As momentum depends on both velocity and the direction of the body's motion, it is quantified by "mass velocity". Since velocity is a vector and mass is a scalar, momentum is a vector quantity. Mass times speed equals momentum.

p = m*v

= 163*14

= 2482 kgm/s

Although these physical variables are comparable, force and momentum differ from one another. Whether it is a pulling or pushing movement, force is often the outside influence acting on a body. The quantity of motion within a moving body is represented by momentum, on the other hand.

"The motion of an item equal to the product of its mass and its velocity" is referred to as momentum. When we say anything has momentum, we are referring to its precise mass and direction of motion.

A simple pendulum's string needs to be 24.8 metres long in order to oscillate precisely once every 10 seconds.

Use the formula for a simple pendulum:

T = 2π √(L/g)

Where T is the period (time to complete a full oscillation), L is the length, and g is the acceleration due to gravity ≈ 9.81 m/s^2.

Since we need to find the Length of the string we'll solve the equation for L.

√(L/g) = T / (2π)

L = [T / (2π) ] ^2 * g = [ 10.0s / (2π) ]^2 * 9.81 m/s^2 = 24.8 m

Maximum instantaneous speed occurs when the mass moves through the region where the spring is compressed.

The rate at which the speed and direction of a moving object alter over time is known as acceleration. An item or point is said to be accelerated when it moves more quickly or more slowly in a straight path. Because the direction is always changing, travel on a circle accelerates even while the speed is constant.

The rate at which an object's velocity alters in relation to time is referred to as acceleration in physics.

The speed of a 12 kg block on a frictionless horizontal surface attached to a light spring (force constant = 0.80 kN/m) when it is 13 cm from its equilibrium position is 1.32 m/s.

The law of the conservation of energy states: “The total energy is constant in any process. It may change form or be transferred from one system to another, but the total is the same.”

Energy can be changed from one form to another (potential energy can be converted to kinetic energy) but the total energy in the domain remains the same.

The equation is:

Total energy = KE + PE

In a spring, the applied force is stored as potential energy which is given by

PE = ½ kx²

And kinetic energy:

KE =  ½ mv²

Remember that energy is the ability to do work and the work done is the force applied to an object and the resulting displacement.

So,

E = Fx

We have,

m = 12 kg

k = 0.8 kN/m

F = 80 N

x = 13 cm ⇒ 0.13 m

To determine the speed, use the equation:

Fx = ½ kx² + ½ mv²

80 (0.13) = ½ (0.8) (0.13)² + ½ (12)v²

10.4 = 0.00676 + 6v²

Answer:

The answer should be about 0.77 m/s.

Explanation:

This is because there is a rightward force of 80 N (the applied parallel force that’s stated)
BUT, there’s also the leftward force which is the potential energy produced by the pulling of the spring,
which equals to: (0.5)*(k, or spring constant, or in this case 800N)*(x, or distance from equilibrium point, or in this case 0.13m)^2 = 0.5*800*0.13*0.13 = 6.76J
This is the work done by the spring, and since work equals Force times Distance(in this case 0.13m) we get 6.76=0.13F, solve for F, F=52N
NOTE: since this is a leftward force, it is a negative force.
This means that there’s a net force of 28N
Since: F=ma, 28=12a
Which is about: 2.33=a
Now, as we know, a equals change in velocity over change in time, so substitute into the equation above:
2.33 = deltaVelocity / deltaTime
deltaVelocity = finalVelocity(at 0.13m) - initialVelocity(in this case 0) = finalVelocity
deltaTime = finalTime(at 0.13m) - initialTime(in this case 0) = finalTime
And so: 2.33 = finalVelocity / finalTime
Rewrite: 2.33*(finalTime) = finalVelocity
As we know: (displacement) = (intialVelocity)*(time) + (0.5)*(acceleration)(time)^2
If we plug in everything we know: 0.13 = 0*t + 0.5*2.33*t^2
Simplify: 0.13 = 1.17*t^2
Solve for t: 0.11 = t^2
0.33 = t
Back to our previous equation: 2.33*(finalTime) = finalVelocity
Plug in 0.33 for time: 2.33*0.33 = finalVelocity = 0.7689
Round off: 0.77 m/s

The penguin that is currently on the outside of the group will eventually be in the middle. Because huddles are dynamic structures, no penguin can stay on the edge for very long.

While swimming in the ocean, a penguin's fat coat shields them from the cold. However, on land, their feathers serve as a means of heat retention. Instead of being long and flat like those of flying birds, penguin feathers are short and contain an underlayer of soft, woolly down. When a penguin comes out of the water, its feathers are excellent at shedding water. They cross each other, creating a good streamlined effect in the water and excellent wind-shedding properties on land. Penguins can puff their feathers out when it's extremely cold to capture more air and provide better insulation.

We know that value of c=3×10⁸m/sec and we have v=20Hz
