When the teacher asked the student to make words out of the jumbled word gzeysktqix, the student was being tested on his ability to unscramble words. Unscrambling words is the process of taking a word or series of letters that are out of order and rearranging them to form a word that makes sense.

When trying to unscramble a word, it is important to look for any patterns that can help identify smaller words within the jumbled letters. This can help make the process easier and quicker. For example, in the jumbled word gzeysktqix, one might notice that the letters "sktqix" appear together.

This could indicate that these letters could potentially form a word. By looking at the remaining letters, one could notice that the letters "g", "z", "e", and "y" could also form smaller words. After some rearranging, the letters can be unscrambled to form the words "sky", "zig", "sex", and "yet". These are just a few examples, as there are likely many other words that can be formed from this jumbled word.

The centripetal acceleration of a point 0.100 m from the center when the wheel is moving at an angular speed of 12.0 rad/s is 1.44 m/s^2.

To find the centripetal acceleration of a point on the grinding wheel, we can use the formula:

a = rω^2

Where:

a is the centripetal acceleration,

r is the distance from the center of the wheel to the point, and

ω (omega) is the angular speed.

Given:

Radius of the grinding wheel, r = 0.150 m

Angular speed, ω = 12.0 rad/s

Distance from the center, r' = 0.100 m

First, we calculate the centripetal acceleration at the given angular speed:

a = (0.150 m)(12.0 rad/s)^2 = 21.6 m/s^2

Now, to find the centripetal acceleration at a distance of 0.100 m from the center, we substitute the new radius into the formula:

a' = (0.100 m)(12.0 rad/s)^2 = 1.44 m/s^2

The displacement at which the kinetic energy and potential energy of a particle executing SHM will be equal when the amplitude is 3cm is 1.5cm.

The amplitude of simple harmonic motion affects the ratio of kinetic to potential energy at a specific displacement in the following way: as the amplitude increases, the ratio of kinetic to potential energy decreases. This is because the amplitude represents the maximum displacement from the equilibrium position, and as the amplitude increases, the potential energy of the particle increases, while the kinetic energy remains constant. Therefore, at a specific displacement, a particle with a larger amplitude will have a greater proportion of its energy in the form of potential energy, while a particle with a smaller amplitude will have a greater proportion of its energy in the form of kinetic energy.

The true statement among the following for the wavelength of a photon emitted when an electron in a hydrogen atom jumps from ni=70 state to the nf=2 is option B. it is shorter.

A photon is a particle representing a quantum of light or other electromagnetic radiation. A photon carries energy proportional to the radiation frequency but has zero rest mass.

Using the below giving equation we can find out the wavelength of the photon emitted when an electron in a hydrogen atom jumps from a higher energy state to a lower energy state

λ = \(R_{H}\) × (1/ni² - 1/nf²)

where  \(R_{H}\) is the Rydberg-constant and ni is the initial quantum number and nf is the final quantum number.

First case, the wavelength of the photon emitted when an electron jumps from the ni=70 state to the nf=2 means

λ(70 to 2) =    \(R_{H}\)* (1/70² - 1/2²)

And then the wavelength of the photon emitted when the electron jumps from the ni=4 state to the nf=2 state can be calculated as:

λ(4 to 2) = \(R_{H}\) * (1/4² - 1/2²)

When we consider these two, we will get that the wavelength of the photon emitted when an electron jumps from the ni=70 state to the nf=2 state is longer than the wavelength of the photon emitted when the electron jumps from the ni=4 state to the nf=2 state.

Explanation:

Answer:

A.  xmax = 131.49 m

B.  t = 8.74 s

C.  ymax = 220.33 m

Explanation:

A. In order to find the horizontal distance which cannon travels you first calculate the flight time. The flight time can be calculated by using the following formula:

\(y=y_o+v_osin\theta-\frac{1}{2}gt^2\)      (1)

yo: height from the projectile is fired = 200m

vo: initial velocity of the projectile = 25m/s

g: gravitational acceleration = 9.8 m/s^2

θ: angle between the direction of the initial motion of the ball and the horizontal = 53°

t: time

You need the value of t when the projectile hits the ground. Then, in th equation (1) you make y = 0m.

When you replace the values of all parameters in the equation (1), you obtain the following quadratic formula:

\(0=200+(25)sin53\°t-\frac{1}{2}(9.8)t^2\\\\0=200+19.96t-4.9t^2\) (2)

You use the quadratic formula to obtain the value of t:

\(t_{1,2}=\frac{-19.96\pm\sqrt{(19.96)^2-4(-4.9)(200)}}{2(-4.9)}\\\\t_{1,2}=\frac{-19.96\pm65.71}{-9.8}\\\\t_1=8.74s\\\\t_2=-4.66s\)

You use the positive value because it has physical meaning.

Now, you can calculate the horizontal range of the projectile by using the following formula:

\(x_{max}=v_ocos\theta t\)      

\(x_{max}=(25m/s)(cos53\°)(8.74s)=131.49m\)

The cannon ball travels a horizontal distance of 131.49 m

B. The cannon ball reaches the canon for t = 8.74s

C. The maximum height is obtained by using the following formula:

\(y_{max}=y_o+\frac{v_o^2sin^2\theta}{2g}\)     (3)

By replacing in the equation (3) the values of all parameters you obtain:

\(y_{max}=200m+\frac{(25m/s)^2(sin53\°)^2}{2(9.8m/s^2)}\\\\y_{mac}=200m+20.33m=220.33m\)

The maximum height reached by the cannon ball is 220.33m

Answer:

0.27km

Explanation:

tanA=\(\frac{a}{b}\)

a=btanA

a=(0.75km)tan20

The dangling mass will not move and the puck will keep rotating in its orbit, Therefore, V = √(mgR/M)  will be an algebraic expression that includes the variables mentioned above.

A centripetal force that causes a body to travel along a curved path. The centripetal force always acts orthogonally to the motion of the body and towards the fixed point of the path's instantaneous centre of curvature. Isaac Newton described it as "a force by which bodies are drawn or impelled, or in any way tend, towards a point as to a centre". Gravity is the centripetal force that causes astronomical orbits, according to Newtonian mechanics theory.

A common example of centripetal force is when a body moves at a constant speed along a circular path. The centripetal force is directed at right angles to the motion as well as along the radius of the circular path towards the centre.

Fc = mg

Now, centripetal force on the puck is equal to the mass of the puck times the centripetal acceleration, or

Fc = Mac

centripetal acceleration is related to the tangential velocity of the puck as

ac = V²/R

where R is the radius of the orbit. Then we have

Fc = M ac =M ω² R = M V² / R

and, thus

M V² / R = mg

and, solving for V, we get

V = √(mgR/M)

In a reference frame fixed to Earth, a point on the equator moves zero distance in 1 hour.

A frame of reference in physics is made up of an abstract coordinate system and the collection of physical reference points that fix the coordinate system specifically and regulate measurements inside it.

When we take a reference frame fixed to Earth,  the displacement due to earth's rotation can not be measured. So, any point on earth remains in rest through out the day with respect to the reference frame fixed to Earth.

Explanation:

The velocity of car 2, from the frame of reference of car 1, is 20 m/s west. (Answer: B)

When considering the frame of reference of car 1, we need to subtract the velocity of car 1 from the velocity of car 2 to determine the relative velocity. Since car 1 is moving at 45 m/s west and car 2 is moving at 25 m/s east, we can subtract these velocities to find the relative velocity of car 2 with respect to car 1.

45 m/s (west) - 25 m/s (east) = 20 m/s (west)

Therefore, car 2 has a velocity of 20 m/s west when observed from the frame of reference of car 1. It is important to note that velocities are vector quantities, which means they have both magnitude and direction. In this case, the direction is west because car 2 is moving in the opposite direction of car 1. (Answer: B)

In the study of physics, we use vectors to represent quantities that have both direction and magnitude. It is often the case that we want to add two or more vectors together to obtain a single vector that represents the net result of these additions. The process of adding two or more vectors together is known as vector addition.The magnitude of the resultant vector is the length of the line that represents it on a scale drawing.

When we add two or more vectors together, the resultant vector is the vector that represents the net result of these additions. To find the magnitude of the resultant vector, we use the Pythagorean theorem, which states that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides.

In the case of vector addition, the hypotenuse is the resultant vector, and the other two sides are the component vectors. If we have two vectors a and b, the magnitude of the resultant vector is given by the following equation:|R| = √(ax2 + bx2)where R is the resultant vector, a and b are the component vectors, and x is the angle between the vectors.
