why is the only option milk?

The Ph for milk is about 6.5 to 6.7,  it varies becauses milks gets sour when it rots.

the speed of sound in air is 343 m/s. Option d (343 m/s) is the correct answer.

How to solve the question?

The speed of sound in air can be calculated using the formula:

v = d/t

Where v is the speed of sound, d is the distance traveled by the sound wave, and t is the time taken for the sound wave to travel that distance.

In this problem, we are given that the distance between the chime and the observer is 515 m, and the time taken for the sound wave to travel this distance is 1.50 s. So, we can use the above formula to calculate the speed of sound:

v = d/t = 515/1.5 = 343 m/s

Therefore, the speed of sound in air is 343 m/s.

Option d (343 m/s) is the correct answer.

It's worth noting that the speed of sound in air can be affected by various factors such as temperature, humidity, and pressure. At a standard temperature of 20°C and normal atmospheric pressure, the speed of sound in air is approximately 343 m/s. However, this value can vary depending on the conditions in which the sound wave is traveling.

Laser light passing through two small slits produces a bright fringe centered at the midpoint on a distant screen because the light waves travel the same distance from each slit to the midpoint.

Considering that light is composed of both electric and magnetic fields, it often acts as an electromagnetic wave. Magnetic fields oscillate perpendicularly to the wave propagation direction and are perpendicular to one another. They are called transverse waves as a result of this. The following are a few traits of light:

When dealing with light waves, the sine waveform is used. One complete sweep from 0 to 360 degrees makes up the waveform's period.

Answer: A. Meters per second squared

Explanation: The internet

5/m/s/s, or 5 meters per second square, can also be used to calculate acceleration.

The acceleration is considered to be zero because when object's velocity stays constant throughout the motion. because the velocity does not alter as the time changes. For instance, an automobile traveling at a steady speed on the roadway has no acceleration. An object is still moving even while it travels in a circle at a constant speed because the orientation of its velocity is changing. A net force affects an object's motion; the greater the neutral energy, the more speed the object experiences.

Given maximum height reached by the ball as H = 40 metres

Since the ball rises straight up when hit by a ball, then the angle of launch will be perpendicular to the ground and that is 90°.

To determine the upward speed of the ball in meters per second after it got struck by the bat, we will use the formula for calculating the maximum height according to projectile motion;

Maximum Height H = \(\frac{u^2sin^2\theta}{2g}\) where;

u is the speed of the ball

\(\theta\) is the angle of launch

g is the acceleration due to gravity = 9.81m/s²

Substituting the given parameters into the formula;

\(40 = \frac{u^2sin^2(90)}{2(9.81)}\\ \\40 = \frac{u^2}{2(9.81)}\\ \\40 = \frac{u^2}{19.62} \\cross\ multiply\\\\u^2 = 40*19.62\\u^2 = 784.8\\u = \sqrt{784.8}\\ u = 28.01 m/s\)

Hence the upward speed of the ball in meters per second after it got struck by the bat is 28.01m/s.

When the roller coaster car is at the top of the loop-de-loop, it has both potential and kinetic energy, and it is moving at approximately 34.9 m/s.

To understand why, let's analyze the energy transformations happening in this situation.At the top of the 93.0 m hill, the car only possesses potential energy given by the equation PE = mgh, where m is the mass of the car (535 kg), g is the acceleration due to gravity (9.8 m/s^2), and h is the height of the hill (93.0 m). Therefore, the potential energy at the top of the hill is PE = (535 kg) * (9.8 m/s^2) * (93.0 m) = 489,315 J.As the car moves down the hill, potential energy is converted into kinetic energy, given by the equation KE = 1/2 * mv^2, where v is the velocity of the car. At the bottom of the hill, all the potential energy is transformed into kinetic energy, so the equation can be rearranged to solve for the velocity: v = sqrt(2 * (PE / m)). Plugging in the values, v = sqrt(2 * (489,315 J / 535 kg)) ≈ 24.6 m/s.

When the car reaches the top of the loop-de-loop, it has both potential and kinetic energy. At this point, the potential energy is given by PE = mgh, where h is the height of the loop (62.0 m). The potential energy is PE = (535 kg) * (9.8 m/s^2) * (62.0 m) = 311,548 J.

The remaining energy is kinetic energy, so we can calculate the kinetic energy using the equation KE = 1/2 * mv^2. Rearranging the equation to solve for v, we get v = sqrt(2 * (KE / m)). Plugging in the values, v = sqrt(2 * (311,548 J / 535 kg)) ≈ 34.9 m/s.
