How do biotic and abiotic conditions change during secondary succession??

Answer:

Explanation:

Given the wave function

y(x,t) = 0.340 sin (15πt − 4πx + π/4)

Generally a wave function is of the form

y(x, t) = A•Sin(wt - kx + θ)

Where

A is amplitude

w is angular frequency

θ is the phase angle

k is the wave number.

Then, comparing this with given wave function

k = 4π, w = 15π and θ = π/4

Speed and direction?

The speed of a wave function can be determined using wave equation

v = fλ

w = 2πf

Then, f = w/2π = 15π/2π = 7.5Hz

Also k = 2π/λ

Then, λ = 2π/k = 2π/4π = 0.5 m

Then,

v = fλ = 7.5 × 0.5

v = 3.75m/s

Direction

Since the time and distance coefficient have opposite sign, for an increasing time interval, the translation will have to increase in the positive direction to nullify the change and maintain the phase. Hence, the wave is traveling in the positive x direction

Answer:  If one billiard ball hits another, the second will move with the same force as the first.

A child wants to jump to climb a tree (reaction), he must push the ground to propel himself (action).

A man deflates a balloon; the force with which the air comes out causes the balloon to move from one side to the other.

Explanation:

-Hitting A Wall

-Rowing a boat

-Walking

Explanation:

1.If you hit a Wall with your hands or legs, you get hurt. Why?

Because of Newton's Third Law. You hit the wall with a force and that exact same amount of force is returned by the wall.

2. While Rowing a boat, when you want to move forward on a boat, you paddle by pushing the water backwards, causing you to move forward.

3.While Walking, You push the floor or the surface you are walking on with your toes, And the surface pushes your legs up, helping you to lift your legs up.

Answer:

Explanation:

As we know that the combination is maintained at rest position

So we will take net torque on the system to be ZERO

so we know that

here we will have

so we have

so we have

Final answer:

The concept of torques and equilibrium is used to calculate the pulling force on the larger flywheel, which is found to be approximately 29.55 Newtons. This force will balance the system and prevent it from rotating.

Explanation:

To solve this problem, we need to understand the concept of torque and equilibrium. We know that torque (τ) is the rotational equivalent of linear force. It's calculated by the formula τ = force × radius. Thus, for the system to stay at equilibrium (not rotate), the torques need to balance each other out.

On the smaller flywheel, the torque τ₁ is given by the pulling force (F₁ = 50 N) and the radius (r₁ = 13 cm, or 0.13 m), hence τ₁ = F₁ × r₁ = 50 N x 0.13 m = 6.5 N.m.

In order for the system to stay at equilibrium, the same amount of torque needs to be applied to the larger flywheel. We already know the radius of the larger flywheel (r₂ = 22 cm, or 0.22 m). To keep the system at equilibrium, the pulling force F₂ on the larger flywheel should be such that the torque τ₂ = τ₁ = 6.5 N.m. From the formula τ = F × r, we can solve for F₂ as follows: F₂ = τ₂ / r₂ = 6.5 N.m / 0.22 m = 29.55 N, approximately. Therefore, a pulling force of about 29.55 N should be applied to the cord connected to the larger flywheel to prevent the system from rotating.

Answer:

To divide the charge q into two parts such that they experience maximum electrostatic repulsion, the charges should be equal in magnitude and opposite in sign. In other words, the charge q should be divided into two equal charges of -q/2 and +q/2. This arrangement will result in the maximum electrostatic repulsion between the charges, as like charges repel each other.
