With a plane mirror, the distance of the image behind the mirror is infinitely far. The greatest distance behind the mirror at which the image can be found is infinite.

For plane mirrors, the object distance is equal to the image distance and hence, the image is the same distance behind the mirror as the object is in front of the mirror.

The image distance from mirror does not depend on the distance of the observer from mirror. Therefore, if we change the object's distance then only the image distance or distance between object and image will be affected.

The vertical component of the velocity is 19.25 m/s.

The vertical component of the velocity can be determined using the trigonometric function of sine.

The sine of an angle is equal to the ratio of the opposite side to the hypotenuse of a right triangle.

In this case, the angle is 37° and the hypotenuse is the velocity, 25 m/s. We need to find the opposite side, which is the vertical component of the velocity.

We can use the equation for the sine of an angle to solve for this:

sin(37°) = Opposite side/25

We can rearrange this equation to solve for the opposite side:

Opposite side = 25 * sin(37°)

Using a calculator, we can determine that the opposite side is equal to 19.25 m/s.

Therefore, the vertical component of the velocity is 19.25 m/s.

The mass of the particle having a de Broglie wavelength of 2.25×10⁻⁹ m and moving with a speed of 2.34×10⁶ m/s is 1.26×10⁻³¹ kg.

The de Broglie equation relating the momentum of a particle with its de Broglie wavelength is given by:

λ=h/Mv

where 'λ' is de Broglie wavelength, 'h' is Planck's constant having its value as 6.626×10⁻³⁴ kg-m²/s and 'M' is the mass of the particle.

Using the above equation and the values of λ=2.25×10⁻⁹ m, v=2.34×10⁶ m/s, and h=6.626×10⁻³⁴ kg-m²/s;

λ=h/Mv

2.25×10⁻⁹ m=(6.626×10⁻³⁴ kg-m²/s)/(M×2.34×10⁶ m/s)

=>M=(6.626×10⁻³⁴ kg-m²/s)/(2.25×10⁻⁹ m×2.34×10⁶ m/s)

The de Broglie wavelength is 6.96 x 10^-33 m of a 1.90 kg rock thrown with a speed of 4.80 m/s into a pond.

λ = h/mv

λ = (6.626 x 10^-34)/(1.90 x 10^-3 x 4.80)

λ = 6.96 x 10^-33 m

Therefore, the de Broglie wavelength is 6.96 x 10^-33 m

De Broglie wavelength is a measure of the wave properties of a particle and is related to the particle's momentum. The equation for calculating the De Broglie wavelength is given by:

λ = h/p

where

λ = De Broglie wavelength

h = Planck's constant (6.626 x 10^-34 J*s)

p = momentum

The momentum of a particle can be calculated using the equation:

p = mv

where

m = mass of the particle

v = velocity of the particle

In this case, the mass of the rock is 1.90 kg and its velocity is 4.80 m/s.

Therefore, the momentum of the rock is:

p = 1.90 kg x 4.80 m/s = 9.24 kg m/s

Now we can calculate the De Broglie wavelength of the rock using the equation:

λ = h/p

λ = (6.626 x 10^-34 J*s) / (9.24 kg m/s)

λ = 7.

The de Broglie wavelength, named after the French physicist Louis de Broglie, is the quantum mechanical property of a particle that describes its wavelike behavior. It is the wavelength of a particle associated with its momentum, and is given by the equation

λ = h/p

where λ is the wavelength, h is Planck’s constant, and p is the momentum of the particle. This equation is important in understanding the behavior of particles in both classical and quantum mechanics. In classical mechanics, particles are described as having a definite position and momentum, and the de Broglie wavelength allows us to calculate the probability of a particle being in a certain position at a given time. In quantum mechanics, the de Broglie wavelength is used to calculate the probability of a particle being in a certain state.

Step 1: Determine the boat's velocity in relation to the river by deducting the river's current from the boat's speed in still water.

Boat speed in relation to the river is equal to 8.0 m/s minus 6.0 m/s, or 2.0 m/s.

In Step 2, multiply the boat's angular velocity to the stream by both the lake's current to determine how fast the sailboat will be traveling across the water.

Boat's river crossing speed is calculated as 2.0 m/s plus 6.0 m/s, which equals 8.0 m/s.

Because of this, the boat is moving at 8.0 m/s as it crosses the river.

An object's mass and the force being exerted towards it both affect how quickly it moves. The speed of an object's movement increases with increasing force.

Using Centripetal Force the Number of revolutions per minute is 0.95rpm, such that the Space statition is rotating in circular path

A force that causes a body to follow a curved path is known as a centripetal force. It always moves in a direction that is the opposite of the body's velocity and in the direction of the immediate center of curvature of the path. It is "a force by which bodies are dragged or driven, or in any other way gravitate, towards a point as to a center," according to Isaac Newton. Gravity is the centripetal force that drives astronomical orbits according to Newtonian mechanics.

A common illustration of centripetal force is when a body moves uniformly fast in a circular motion. The centripetal force is directed towards the center of the circular route both along the radius and at right angles to the motion.
