a gun with a muzzle velocity of is fired at an angle of above the horizontal. find the horizontal and vertical components of the velocity.

The positive x direction is 0 Nm, positive y direction is 10 Nm, negative x direction is 0 Nm.

The torque, also known as the moment of force, is given by the cross product of the position vector (r) and the force vector (F).

The magnitude of the torque is given by the magnitude of the cross product, which is equal to the product of the magnitudes of the vectors (r and F) multiplied by the sine of the angle between them.

In the case of (a) positive x direction, the torque about the origin is given by:

τ = r x F = (2.0 m) x (5.0 N) x sin(90°) = 3.0 m x 5.0 N = 0 Nm.

In the case of (b) positive y direction, the torque about the origin is given by:

τ = r x F = (3.0 m) x (5.0 N) x sin(90°) = 2.0 m x 5.0 N = 10 Nm.

In the case of (c) negative x direction, the torque about the origin is given by:

τ = r x F = (2.0 m) x (-5.0 N) x sin(90°) = 3.0 m x 5.0 N = 0 Nm.

So, the positive x direction is 0 Nm, positive y direction is 10 Nm, negative x direction is 0 Nm.

A boy of mass 60 kg grams up a set of stair of total in 3 metre work done in joule is 1800 J.

Option B is correct.

Given: Mass of the boy, m = 60 kg

Total height of steps, h = 3 m

Acceleration due to gravity, g = 10 m/s²

➜ Work done = force × displacement

➜ Force = mass × acceleration

Acceleration due to gravity, g is 10 m/s².

∴ Force = mass × acceleration due to gravity

➜ Work done = mass × acceleration due to gravity × displacement

A/C to given problem, boy runs up a set of steps of total height 3 m hence displacement is 3m.

➜ Work done = 60 × 10 × 3

➜ Work done = 600 × 3

➜ Work done = 1800 Joule

A force's work is the sum of the object's applied force in the direction of the displacement and the object's displacement. The body moves with some acceleration when we push a block with some force, and the work is finished.

An object should be transformed into energy in order to move. The use of force can be used to transfer energy. Work done refers to the amount of energy transferred by force to move an object.

W=Fs is used to calculate the amount of work done on an object when it is moved x distances by a force F. We add a minus sign if the force is in the opposite direction of the object's movement.

You can start the problem by using the formula for capacitance, C = Q/V, where C is the capacitance, Q is the charge stored on the capacitor, and V is the potential difference across the capacitor.

A capacitor is a passive electrical component that stores electrical energy in an electric field. It consists of two conductive plates, separated by an insulating material called the dielectric. When a voltage is applied across the conductive plates, an electric field is created, which stores energy in the dielectric. The ability of a capacitor to store electrical energy is measured in farads (F).

Given that Capacitor 2 has half the capacitance and twice the potential difference as Capacitor 1, you can express the capacitance and potential difference of Capacitor 2 in terms of those of Capacitor 1.

C₂ = 1/2 × C₁ V₂ = 2 × V₁

You can use these equations to find the ratio of the stored energy in the two capacitors. The stored energy in a capacitor is given by the formula U = 1/2CV², where U is the stored energy, C is the capacitance, and V is the potential difference.

Uc1 = 1/2C₁V₁² Uc2 = 1/2C₂V₂²

By substituting the values of C₂ and V₂ in terms of C₁ and V₁, you can find the ratio of the stored energy in the two capacitors:

Uc1/Uc2 = (1/2C₁V₁²) / (1/2×(1/2C₁) (2V₁) ²) Uc1/Uc2 = 1/8

The ratio of stored energy in the two capacitors is 1/8.

The ratio of the mother's speed to the son's speed is equal to 0.5.

Kinetic energy is defined as K = 1/2 * m * v^2, where m is the mass of the object and v is its velocity. Since both the mother and her son have the same kinetic energy, we can write:

1/2 * m_mother * v_mother^2 = 1/2 * m_son * v_son^2

Since the mother has four times the mass of her son, we can substitute:

m_mother = 4 * m_son

We can substitute this into the equation:

1/2 * 4 * m_son * v_mother^2 = 1/2 * m_son * v_son^2

We can then divide both sides by 1/2 * m_son to get:

4 * v_mother^2 = v_son^2

We can then take the square root of both sides:

v_mother  * sqrt(4)= v_son

The correct answer is transmission, term describes the process by which light passes through an object or a medium is called transmission.

The experience of light is crucial to human life. Because of the sun's light, we can grow the food we eat, and we can also see because when we view anything, a particular wavelength of light is reflecting off the thing and reaching our eye. Even an object's color is influenced by light. But how does light move, and how does it interact with things once it gets there? What happens to light as it strikes objects around us will be covered in this session.

The tiny particles that make up light are known as photons. Due of their dual behavior as a particle and a wave, photons are incredibly intriguing.

A mirror reflects light when it is shone upon it, much like a bouncing ball or any other particle might. Imagine shining a light through a keyhole so that it illuminates the entire space rather than just a small portion of it, as a laser would. Similarly, if someone shouted through that keyhole, it would be heard across the entire room, not only in that one area. Since sound is also a wave, this is also how light behaves as both a wave and a particle.

The two best ways to measure the distance to a distant, isolated spiral galaxy are by using the redshift of the galaxy and/or by using the Cepheid variable star method.

Distance is a numerical measurement of how far apart two objects, points, or locations are. It is a measure of space in terms of length, width, or height. Distance can be measured in a variety of units including miles, kilometers, yards, and feet. Distance can also be measured in time, such as the amount of time it takes to travel from one location to another. Distance is an important concept in many areas of life, from transportation to navigation to sports.
The redshift of a galaxy is a measure of the expansion of the universe, and is determined by the Doppler Effect. It is calculated using the wavelength of a galaxy's light and the frequency of that light. Redshift can be used to measure the distance of a galaxy by comparing the redshift of the galaxy with the redshift of a standard reference. The further away a galaxy is, the greater its redshift will be.

The Cepheid variable star method is also a reliable way of measuring the distance of a distant spiral galaxy. Cepheid variable stars are stars that pulsate at a regular period, and they can be used as a “standard candle” of sorts, because their luminosity is related to their period. By measuring the period and luminosity of Cepheid variable stars in a distant spiral galaxy, astronomers can calculate the distance to that galaxy.

The force exerted by the water on the wall will be equal to 160 N. Newton's third law of motion is seen taking place here.

The force exerted by the water on the wall is calculated using the impulse-momentum principle. The principle states that the change in momentum of an object is equal to the impulse, or the force applied over a certain period of time. In this case, the change in momentum is equal to the initial momentum of the water (mass flow rate multiplied by velocity) minus the final momentum of the water (mass flow rate multiplied by final velocity) and the time is assumed to be very small.

The assumptions made in the calculation of force exerted by the water on the wall are:

The water hits the garage instantaneously.

The water flow rate is constant and no water is lost during the impact.

The water hits the garage uniformly over the entire area and not just at one point.

The garage door is not moving before the impact. These assumptions are made to simplify the calculation and to make it more accurate. It is important to note that in real-world scenarios, these assumptions may not always hold true and the force exerted by the water on the wall may be different.

Force exerted by the wall on the water, F = dP/dt

= (P2 - P1)/dt

= dm*(V2 - V1)/dt

= (V2 - V1) x dm/dt

= (0 - 16) x 10

Vertical component of the u, = usinθ

Horizontal downrange, R = ucosθ×T
