Answer:

Acceleration is any change in velocity.

Explanation:

Speed is not always changing when accelerating. In fact, when an object moves in a circular path at a constant speed, it is still accelerating, because the direction of its velocity is changing. So the correct answer is velocity.

Answer:

Walking,horse pulling the cart, firing of a gun

Explanation:

when we walk we exert force on earth, earth exerts equal force of us

horse applys force in in opposite direction on earth,earth applys equal force and it pulls the cart

when we fire a gun,it apply equal force of us.It is called recoil velocity of a gun

Electric circuits are closed paths consisting of electrical components and conductive wires. The electric charge will flow in an electric circuit when the circuit is connected to a source of power, such as a battery.

The movement of electric charges in a circuit is due to the potential difference between the two points of the circuit, i.e. the voltage. A voltage source in the circuit produces an electric field which exerts a force on the charges. This force pushes the electric charges around the circuit, creating a current. The current is a measure of the rate at which electric charges flow through a circuit. The movement of charges in a circuit is dependent on the electrical resistance of the components.

The electrical resistance of a component is the degree to which it resists the flow of electric current through it. In a circuit, the electrical resistance of a component is measured in Ohms (Ω). The higher the resistance of a component, the less current that will flow through it. Electric circuits can be designed to control the flow of electric charge, such as switching circuits on and off or adjusting the amount of current flowing through a component. The electric charge flow can also be used to produce useful work, such as powering lights, appliances, or machines.

Answer:

hydrophobicity and lower density

because floats on the surface of the water.

Answer:

1) False, since constant speed means constant velocity, but with constant direction as well. Velocity is speed with direction. When you move in a circle, there are boundaries which means that a constant moving speed will cause the object to veer(move in different directions) to maintain movement, If it doesn't veer, the object will deflect(rebound) off the surface due to friction, and impact force or depending on its physical bond of malleability or density.

2a) Create position vectors by drawing a ray from the center(origin) of the circle to each of your desired points, it's magnitude will be the radius(how convenient).

1. The box will move to the right with a force of 50 N when a 75 N force is applied to the left.

2. The box will not move if a 50 N force us applied to the left.

For  Balanced, B or Unbalanced forces, U the correct option are:

Balanced forces are forces that do not produce an acceleration of an object. Net force will be zero.

Unbalanced forces are forces that produce an acceleration of a body. Net force will be greater than zero.

Considering the boxes:

1. Net force = 50 N

Forces to the left = 25 N + x

Forces to the right = 50 N

Net force = Force to the left + force to the right

50 N = 25 N + x - 50

x = 75 N

2. Net force = 0 N

Forces to the left = 75 N + x

Forces to the right = 125 N

Net force = Force to the left + force to the right

0 N = 75 N + x -125

Answer:

According to Newton's third law of motion, the reaction force is equal to the action force.

Explanation:

Newton's third law of motion states that for every action there is an equal and opposite reaction. This means that if one object exerts a force on a second object, the second object exerts an equal force in the opposite direction. When Plate X pushes on Plate Y with the action force (Fx), Plate Y must push back with an equal force (Fy).

Therefore, the best explanation is that according to Newton's third law of motion, the reaction force is equal to the action force.

For every action, there has equal and opposite reaction - this statement best describes the action and reaction forces on the plates.

As a result of this interaction, there are two forces: one from plate X and one from plate Y. The third law of motion of Newton deals with these two forces, which are referred to as action and reaction forces. Newton's third law is officially expressed as follows: There is an equal and opposite reaction to every action.

The implication of the statement is that there are always two forces acting on the two interacting objects. The force acting on the first object is equal in size to the force acting on the second. The force acting on the first object is acting in the opposite direction to the force acting on the second object. Force pairs—equal and opposing action-reaction force pairs—always exist in pairs.

The maximum speed the bob of the pendulum attains is nearly 5.97 m/s.

The velocity changes continuously as the pendulum bob moves back and forth. There are times when the velocity is negative (when the pendulum bob is moving left) and other times when it is positive (when it is moving right). And, of course, there will be times when the velocity will be 0 m/s.

From the energy conservation statement

Ui + Ki = Uf + Kf

Ki = 0 as the ball is released from the state of rest.

Uf = 0 where Uf is the final potential energy

So Ui = Kf or mgh = ½ mv², where h is the height from which the ball is released.

Cancelling m on both sides we get

v = (2gh)½

To determine the height h

h = L - Lcos θ = L (1-cos θ)

h =  2 - 2× 0.09 = 1.82

So  v = (2gh)½

v =( 2 × 9.8 × 1.82)¹/²

v = √35.672

When comparing the relative intensities of the spectra of H2 and D2, it is important to note that D2 has a higher molecular weight and therefore a lower vibrational frequency than H2. This means that the Raman rotation spectrum of D2 will have a lower frequency range and more intense lines than that of H2.

To yield lines alternating in intensity and having a relative intensity of 1/2, the Raman rotation spectrum of D2 would be the better choice. This is because the alternating intensity pattern is a result of the Jahn-Teller effect, which is more pronounced in molecules with lower symmetry, such as D2. The relative intensity of 1/2 is a consequence of the Raman selection rules, which dictate that only half of the vibrational modes will be active in the Raman spectrum. Therefore, the Raman rotation spectrum of D2 is more likely to exhibit this alternating intensity pattern with a relative intensity of 1/2.

This is because the Raman effect is based on the inelastic scattering of light by molecules, which depends on the polarizability of the molecules, and the polarizability is affected by the molecular mass.

The Raman Effect is a physical phenomenon discovered by the Indian physicist Sir C.V. Raman in 1928. It refers to the scattering of light by molecules, where the scattered light undergoes a shift in wavelength due to the interaction with the molecular vibrations. This shift is known as the Raman shift and it provides important information about the molecular structure, chemical composition, and physical properties of the substance being studied.

The Raman Effect occurs when a photon of light interacts with a molecule, causing the molecule to become excited and vibrate. As the molecule returns to its ground state, it emits a photon of light with a different energy, resulting in a shift in wavelength. This shift is characteristic of the molecule and can be used to identify it. The Raman Effect has many applications, including in materials science, chemistry, biology, and medicine. It is used to identify and study the properties of molecules, including those that are difficult to analyze by other means.

EXPLANATION

Magnification is a measure of an image's size compared to the size of the object that formed the image.

Since magnification is a ratio that is proportional to the sizes of the image and object, it follows that if magnification is less than 1, the image is smaller than the object, if magnification is equal to 1, the image and object are the same size and if magnification is greater than 1, the image is larger than the object.

Therefore, it is False.
