According to the given statement 9.91m/s was the initial speed given to the rock.

The pace at which a distance changes over time is referred to as speed. It has a dimension of time-distance. As a result, the fundamental unit of time or the basic unit de distance are combined to form the Vernier scale of speed. Thus, the metre per second (m/s) is the Standard unit of speed.

y\(_f\) = y\(_i\) + v\(_y_i\)t + 1/2 at²

-40.0 m = 0 + 0 + 1/2 (-9.80m/s²)t²

t = 2.86s

The additional time needed for the sound she hears to return directly to the player is

3.00s-2.86s=0.140s.

It travels a long way

(343m/s)0.143s=49.0m= √x²+(40.0m)²

where x is the rock's horizontal travel distance. x=28.3m is obtained by solving for x. The rock is in flight for 2.86 seconds and moves horizontally while maintaining a constant velocity in the x direction.

x=28.3m=v\(_x_i\)t+0t²

v xi​ = 28.3m / 2.86s

=9.91m/s

The planet with the strongest magnetic field in the solar system and capable of producing the strongest low-frequency radio emissions detectable by ground-based radio telescopes is Jupiter (option e).

Jupiter has an incredibly strong magnetic field, which is around 20,000 times stronger than Earth's magnetic field. This intense magnetic field is generated by the planet's rapid rotation and its metallic hydrogen interior.

Jupiter's magnetic field interacts with its surrounding environment, specifically its moon Io, which has active volcanoes that emit charged particles.

These charged particles get trapped in Jupiter's magnetic field and create powerful radio emissions. These emissions are primarily detected at low frequencies and can be easily observed by ground-based radio telescopes.

While other gas giants in the solar system, such as Saturn, Uranus, and Neptune, also have strong magnetic fields,

Jupiter's magnetic field is the strongest, making it the most significant source of low-frequency radio emissions among the listed options.

The "max out" method, also known as the "1RM" (One Repetition Maximum) method, is commonly used in strength training to determine the maximum amount of weight an individual can lift for a particular exercise.

The purpose of this method is to assess muscular strength accurately. While it is essential to perform warm-up sets to prepare the body for intense lifting, the process of determining the 1RM involves a specific protocol:

Warm-up Sets: Before attempting the 1RM, it is crucial to warm up the muscles and joints properly. Warm-up sets are typically performed with lighter weights and higher repetitions to gradually prepare the body for the heavier load.

Complete Sets: After the warm-up sets, the individual performs one or more "complete sets" with progressively heavier weights, but not at maximal effort. These sets help acclimate the body to heavier loads and prepare the nervous system for the upcoming maximal lift.

1RM Attempt: Once adequately warmed up and prepared, the individual makes an attempt to lift the heaviest weight possible for one repetition. It is essential to have a spotter or a qualified trainer to ensure safety during this maximal effort lift.

Rest: After the 1RM attempt, it is essential to allow sufficient rest and recovery, as attempting maximal lifts can be physically and mentally demanding.

It's important to note that determining 1RM carries a higher risk of injury compared to typical strength training. It's best to perform 1RM assessments under the guidance of a qualified trainer or coach who can provide proper instruction and ensure safety throughout the process. Additionally, the 1RM should be assessed periodically, as it can change over time with training and adaptation.

Referring to the sketch of a planet around the sun, Area A is three times that of Area B the time \(t_{a}\) is three times \(t_{b}\) .

The orbit of an object is its course through space. Kepler first believed that planets' orbits were circular, but this incorrect assumption prevented him from discovering orbits that were consistent with Brahe's observations. He ultimately learned from the data for Mars that its orbit resembled an elliptical version of a slightly flattened circle. The ellipse is the most basic closed curve after the circle and is a member of the conic section family of curves.

This characteristic proposes a quick method for creating an ellipse. Two tacks are inserted into a drawing board through a sheet of paper, and the ends of a loop of string are wrapped around them to create slack by a planet.

The number of loops in the output coil are 238 loops.

In a step-up transformer, the relationship between the number of turns in its primary coil Np, the number of turns in its secondary coil Ns, the input voltage Vp, the output voltage Vs, the input current Ip and the output current Is is given by:

Ns/Np = Vs/Vp = Ip/Is

Now, we need the relation between number of loops and current:

Ns/Np = Ip/Is

Given that, Np = 238 loops

Ns = ?

Ip = 2 A

Is = 2 A

Now, let us put the values in the above relation.

Ns = Ip/Is * Np = 2/2 * 238 = 238 loops

Thus, number of loops in output coil are 238 loops.

When you see a plain measurement such as 4.2s, 6 ft, it is usually a scalar one.

A very low pH means high acidic water and the water will contain high concentration hydrogen ions [\(H^+\)].

pH scale helps us to measure the acidic or basic nature of a substance or water.

In general, pH measures the relative amount of free hydrogen ion [\(H^+\)] and hydroxyl ions [\(OH^{-1}\)] present in a water.

Thus, a very low pH means high acidic water and the water will contain high concentration hydrogen ions [\(H^+\)].
