Answer:

0.3 s -0.4 m -0.57 m

0.5 s -1.2 m -1.27 m

0.7 s -2.3 m -2.4 m

Explanation:

Answer:

Time  y position (predicted)  y position (measured)

0.3 s -0.4 m                        -0.57 m

0.5 s -1.2 m                        -1.27 m

0.7 s -2.3 m                        -2.4 m

The predicted and measured positions are very close, but the measured positions are all a bit higher. Rounded to one decimal place, the last two measured values are 0.1 meters greater than the predicted values.

My hypothesis is that since the video captures frames only every 0.1 seconds, it’s possible that the frame showing t=0.0 is actually a bit before or after the actual time the ball is released. Any significant difference in identifying the actual zero point would affect agreement between the calculations and the observations.

Explanation:

The following information on a particular compound (Compound X) that has been visualized by means of thin-layer chromatography  the Rf of the compound is  0.334

Rf = 50/150

Rf = 0.334

Separating ingredients in a mixture using chromatography is a procedure. The mixture is dissolved in the mobile phase, which starts the process off, and then transports it through the stationary phase, which is the final phase.

As the combination moves through the stationary phase, the various components separate from one another due to the varying speeds at which they move through the stationary phase. Which chemicals move faster or slower and how they are separated depend on the characteristics of the specific mobile and stationary phases. Retention time describes these different travel times. The method that was originally employed to separate the pigments in a complicated combination in the late 19th century bears the name "chromatography."

I would choose the option B.

F = ma

a = 75 / 25 = 3 m/s^2

The acceleration of the given object will be equal to 3 m/s². Therefore, option (B) is correct.

Acceleration of an object can be explained as the change in the velocity of an object with respect to time. The acceleration is a vector quantity as it exhibits magnitude and direction. Acceleration can be calculated from the 2nd derivative of the position of the object w.r.t. time.

The force is the product of the mass and acceleration, according to Newton's second law of motion.

F = ma

And,   a = F/m

From the above formula, we ca say that the acceleration is inversely proportional to mass.

Given, the force acting on the object, F = 75 N

The mass of the object, m = 25.0 Kg

The acceleration of the given object, a = 75/25 =3 m/s²

Therefore, the acceleration of the object is equal to 3 m/s².

Answer:

(a) The projectile takes approximately 4.420 seconds to reach the water, (b) The horizontal scope of the projectile is 1591.2 meters, (c) The remaining height to descend after 2 seconds of being launched is 63.624 meters.

Explanation:

The projectile experiments a parabolic motion, where horizontal speed remains constant and accelerates vertically due to the gravity effect. Let consider that drag can be neglected, so that kinematic equation are described below:

\(x = x_{o}+v_{o,x} \cdot t\)

\(y = y_{o} + v_{o,y}\cdot t +\frac{1}{2}\cdot g \cdot t^{2}\)

Where:

\(x_{o}\), \(y_{o}\) - Initial horizontal and vertical position of the projectile, measured in meters.

\(v_{o,x}\), \(v_{o,y}\) - Initial horizontal and vertical speed of the projectile, measured in meters per second.

\(t\) - Time, measured in seconds.

\(g\) - Gravitational acceleration, measured in meters per square second.

\(x\), \(y\) - Current horizontal and vertical position of the projectile, measured in meters.

Given that \(x_{o} = 0\,m\), \(y_{o} = 80\,m\), \(v_{o,x} = 360\,\frac{m}{s}\), \(v_{o,y} = 0\,\frac{m}{s}\) and \(g = -9.807\,\frac{m}{s^{2}}\), the kinematic equations are, respectively:

\(x = 360\cdot t\)

\(y = 80-4.094\cdot t^{2}\)

(a) If \(y = 0\,m\), the time taken for the projectile to reach the water is:

\(80 - 4.094\cdot t^{2} = 0\)

\(t = \sqrt{\frac{80}{4.094} }\,s\)

\(t \approx 4.420\,s\)

The projectile takes approximately 4.420 seconds to reach the water.

(b) The horizontal scope is the horizontal distance done by the projectile before reaching the water. If \(t \approx 4.420\,s\), the horizontal scope of the projectile is:

\(x = 360\cdot (4.420)\)

\(x = 1591.2\,m\)

The horizontal scope of the projectile is 1591.2 meters.

(c) If \(t = 2\,s\), the height that remains to descend is:

\(y = 80-4.094\cdot (2)^{2}\)

\(y = 63.624\,m\)

The remaining height to descend after 2 seconds of being launched is 63.624 meters.

The reactance in a purely inductive load if we increase the driving angular frequency will also increase .

An inductor is defined as a passive component that is used in most electrical circuits to store energy in the form of magnetic energy when electric current flows through it. It is also known as the coil, choke, or reactor. It is a two-terminal electrical component that is characterized by its inductance.

Inductive reactance is the property of an inductive coil that resists the change in alternating current (AC) through it and is similar to the opposition to direct current (DC) in a resistance.

Inductive reactance = angular frequency * inductance

X (L) = ω L

The inductive reactance of an inductor is directly proportional to  angular frequency . Hence , if reactance in a purely inductor increases if there is an increase in angular frequency .

The slope shows that the “Inductive Reactance” of an inductor increases as the supply frequency across it increases. Then we can see that at DC an inductor has zero reactance (short-circuit), at high frequencies an inductor has infinite reactance (open-circuit).

Answer:

A

Explanation:

The image that shows an alignment of earth, moon and sun during spring tide is option A. All of them will be in a straight line.

A spring tide is a type of tide that occurs when the Earth, sun, and moon are aligned in a straight line. During a spring tide, the gravitational pull of the sun and the moon combine, resulting in higher-than-normal high tides and lower-than-normal low tides.

During a spring tide, the position of the sun, moon, and earth is aligned in a straight line. The gravitational force of the moon and sun both act upon the oceans of the Earth, creating a combined effect that results in unusually high tides.

During a spring tide, the moon is either new or full, which means it is in a position that aligns with the sun and Earth. The gravitational pull of the moon and sun reinforce each other, creating a stronger gravitational force on the Earth's oceans.

This causes the water level to rise higher than normal during high tide and lower than normal during low tide. Here, image A shows the correct alignment.

The ball must be thrown down with a velocity of 14 meters per second in order to bounce 10 meters higher than its original level, neglecting any energy losses in striking the ground.

To determine the speed at which a ball must be thrown down to bounce 10 meters higher than its original level, we can use the principle of conservation of energy. Neglecting energy losses due to air resistance and assuming an idealized situation, we can equate the potential energy gained during the bounce to the kinetic energy of the ball before it hits the ground.

The potential energy gained by the ball during the bounce is equal to the gravitational potential energy at the new height, which can be calculated as mgh.

where

m = mass of the ball,

g = acceleration due to gravity (approximately 9.8 m/s²)

h = height gained (10 meters in this case).

The kinetic energy of the ball just before it hits the ground is given by (1/2)mv²,

where

v = velocity of the ball.

Equating these two energies, we have:

mgh = (1/2)mv²

Canceling out the mass (m) from both sides of the equation, we get:

gh = (1/2)v²

Simplifying further, we have:

v = √(2gh)

Substituting the values of g (9.8 m/s²) and h (10 meters), we can calculate the velocity (v):

v = √(2 * 9.8 * 10) ≈ √(196) ≈ 14 m/s

Therefore, the ball must be thrown down with a velocity of approximately 14 meters per second in order to bounce 10 meters higher than its original level, neglecting any energy losses in striking the ground.

The statement that most of the moons of the jovian planets have the potato-like shapes of asteroids, but a few are large enough to be spherical in shape is true. Option A.

Many of the moons of the jovian planets are irregularly shaped and most of them have heavily cratered surfaces, similar to asteroids. However, some of the larger moons, such as the four Galilean moons of Jupiter and Saturn's Titan, are large enough to be rounded by their own gravity, resulting in a spherical shape.

All of the moons are airless and barren and most of them are made up of rock and metal, with a few exceptions. Even the largest of the moons are smaller than any of the planets or dwarf planets in our solar system. For example, Jupiter's largest moon Ganymede is only 5262 km in diameter, while the planet Neptune is 49528 km in diameter.

So, it took 1 second to achieve the highest point of trajectory. When the stone achieves it, its have velocity 0 and begin to fall, and it takes also 1 second to return to the top of the platform, so it means that during 2 seconds of the motion. The stone achieves the same high as the platform with the velocity of 10 m/s
