The fundamental frequency of the air column is 150 Hz.

The fundamental frequency of an air column in a pipe closed at one end is related to the frequency of the first harmonic (also known as the first overtone or the fundamental mode) by the equation:

f1 = (2Lc)/n

where L is the length of the air column, c is the speed of sound in air, and n is the harmonic number (1 for the fundamental frequency, 2 for the second harmonic, etc.).

If two consecutive harmonics of an air column have frequencies of 150Hz and 250Hz, we can use these frequencies to calculate the fundamental frequency by solving the equation for n=1 and n=2.

For n=1:

150Hz = (2Lc)/1

For n=2:

250Hz = (2Lc)/2

Dividing the two equations:

(250Hz * 2) = (150Hz * 1)

Lc = (150Hz * 1) / 2

And now we can calculate the fundamental frequency

f1 = (2Lc) / 1 = 2 * (150Hz * 1) / 2 = 150Hz

The fundamental frequency of the air column is 150 Hz.

Energy is you go over a bump in the road too fast, and the vehicle goes slightly airborne.

When your vehicle's tires lose traction with the road surface, it is hydroplaning. If you're driving in the rain and there's more water on the road than your tires can safely push away, you could find yourself unable to control the steering, speed and braking of your vehicle.

You'll get the best traction by straightening the wheel, so do this as much as your parking situation allows. Put your vehicle in the lowest gear. If you've got a four-wheel drive SUV or pickup, engage the low-range gearing. Move forward just a bit.

Therefore, the minimum surface temperature for a star whose emission peaks at a wavelength less than 400 nm is around 7248 K.

the minimum surface temperature of a star whose peak emission is in the ultraviolet, with a wavelength less than 400 nm.

The ultraviolet region of the spectrum is between about 10nm and 400nm, so for a wavelength of 400nm, we can use Wien's law to find the temperature:

400 x 10^-9m = 2.898 x 10^-3m K / T

T = 2.898 x 10^-3m K / (400 x 10^-9m)

T = 7248K (approximately)

The momentum of the ball after being hit by the club can be calculated using the formula p = mv, where p is momentum, m is mass, and v is velocity. Since the force exerted on the ball is known (2380 N) and the time over which the force is exerted is also known (0.00100 s), we can use the formula F = ma to find the acceleration of the ball, where F is force, m is mass, and a is acceleration.

F = m*a

a = F/m

a = 2380 N / 0.0459 kg

The acceleration of the ball is 51760 m/s^2

Next, we can use the kinematic equation v = u + at to find the velocity of the ball, where v is final velocity, u is initial velocity and t is time.

v = u + at

u = 0 m/s (initial velocity)

t = 0.00100 s (time)

v = 0 + (51760 m/s^2)*(0.00100 s)

v = 5.176 m/s

Finally, we can use the momentum formula

p = m*v

p = (0.0459 kg)*(5.176 m/s)

p = 238.64 Ns (Newton second)

Therefore, the momentum of the ball after being hit is 238.64 Ns.

Answer: Yes!

Explanation: Think of a number graph. If we go right it will be positive and if we go left it'll be negative. Like this the velocity can me negative or positive based on the direction.

As the ball's critical frequency rises, the bounce speed gradually accelerates.

g = acceleration

= A[tex]w^2[/tex]

=[tex]A(2p\pi fb)^2[/tex].

The slow-increasing g stands for the ball's gravitational acceleration.

The acceleration of an object in free fall in a vacuum is known as the gravitational acceleration. This is the constant acceleration brought on just by the gravitational pull.

Let's assume that fb is the ball's crucial frequency and that A is its amplitude. The ball's gravitational acceleration can be expressed as follows at a certain point. In this case, the frequency of the ball's bounce affects the acceleration of the ball.

Therefore, we can infer that as fb increases, the bounce speed increases gradually.

The 18 kg child must sit 3.3 meters from the fulcrum to balance the system.

To determine the distance from the fulcrum at which an 18 kg child must sit on a seesaw to balance a 30 kg child sitting 2.0 m away from the fulcrum, you can use the principle of moments.

The principle of moments states that for a system to be in equilibrium (i.e., balanced), the clockwise moments (force x distance) must be equal to the counterclockwise moments.

We know the weight of the 30 kg child is 30 x 9.8 = 294 N (Newtons), and it is 2.0 m away from the fulcrum. Therefore, the clockwise moment is 294 x 2 = 588 Nm.

The weight of the 18 kg child is 18 x 9.8 = 176.4 N.

To balance the system, the counterclockwise moment must also be 588 Nm. Therefore, the distance from the fulcrum at which the 18 kg child must sit is:

588 Nm = 176.4 N x d

d = 588/176.4 = 3.3 meters

So, the 18 kg child must sit 3.3 meters from the fulcrum to balance the system.

Given the charge on object A is (Q1) = 1.8 x 10^-6C

The charge on object B is (Q2) = -1.0 x 10^-6C

They are separated at a distance of (r) = 0.014m = 1.4 x 10^-2m

The force of attraction between them is calculated as (F) = kQ1Q2/r^2

where k = 9 x 10^9

Since they are unlike charges they will be attracted to each other.

F = 9 x 10^9 x 1.8 x 10^-6 x 1 x 10^-6 / (1.4 x 10^-2)^2 = 82.6 = 83N

We are given that the object is 15.0 cm tall and 12.0 cm away from the mirror, which has a focal length of 4.8 cm. The image is 8.0 cm in front of the mirror. By substituting the given values into the mirror equation, we can solve for d_i: 1/4.8 = 1/12 + 1/d_i. d_i = 8cmNow we can use the magnification equation m = -d_i/d_o = -8/12 = -2/3. The negative sign indicates that the image is inverted. We can use the magnification equation to calculate the height of the image:

h_i = m * h_o = h_i = (-2/3) * 15.0= h_i ≈ -10 cm

So the approximate height of the image is -10 cm.A concave mirror has a reflective surface that is curved inward and away from the light source.

The initial velocity of the car is 17 meters per second. It is accelerated at 3m/s^/2.

Acceleration is the rate of change in both speed and direction of velocity over time. When anything moves faster or slower in a straight line, it is said to have been accelerated. Because the direction is always shifting, motion on a circle accelerates even while the speed is constant.

Given -

A car moving on a straight road at 5 m/s.

It is accelerated at 3 m/s^2.

The first equation of motion is,

v = u + at

It gives the velocity acquired by a body in time t.

Here,

initial velocity = u

acceleration = a

time = t

final velocity = v

Therefore, now putting up the values.

v = u + at

→ u = 5 m/s

→ a = 3 m/s²

→ t = 4 sec

⇒ v = 5 + 3 × 4

⇒ v = 5 + 12

According to the information provided, it is 80 cm away from the converging lens on the other side of the item. The picture is 4 cm tall when inverted, or -4 cm.

Diverging lenses are concave, whereas convergent lenses are convex. Diverging lenses diverge the material falling on their surface rather of focusing it to gather at a single point, whereas convergent lenses converged & focus the light beam to do so. When parallel light beams strike a concave lens, they diverge when they travel through the lens and never come together at a single spot. They are known as diverging lenses for this reason.

Knowing that 1/f = 1/v - 1/u

Therefore u = -80, f = 40, v = 80

The ball will hit the ground 54.4 meters from the base of the cliff. This can be determined using the equation for the horizontal range of a projectile, which is x = vx*t. In this case, vx is 11.5 m/s, and t is the time it takes for the ball to reach the ground. This time can be determined using the equation for the vertical range of a projectile, which is y = vyo*t + 0.5*g*t^2. In this case, vyo is 0 m/s (since the ball is thrown horizontally), g is 9.81 m/s^2, and y is 45.2 m (the height of the cliff). Solving for t gives us 3.86 seconds. Plugging this value into the equation for the horizontal range gives us x = 54.4 m.

Answer:

Explanation:

Friction between two surfaces is caused by the contact between them. When two surfaces interact, the roughness of the surfaces combine with the contact force to create a force that resists the motion of the surfaces. When two surfaces are moving relative to each other, the contact force must overcome the friction force in order for the surfaces to move.

Friction can be reduced by either reducing the contact force, or by making the surfaces smoother. One way to reduce the contact force is by using a lubricant, such as oil or grease, to reduce the amount of contact between the surfaces. This reduces the force of friction and allows the surfaces to move more easily. Another way is to make the surfaces smoother, which reduces the amount of roughness and therefore reduces the friction. This can be done with sandpaper or other abrasive materials.
