Answer:

X = 2146.05 m

Explanation:

We need to understand first what is the value we need to calculate here. In this case, we want to know how far from the starting point the package should be released. This is the distance.

We also know that the plane is flying a certain height with an specific speed. And the distance we need to calculate is the distance in X with the following expression:

X = Vt   (1)

However we do not know the time that this distance is covered. This time can be determined because we know the height of the plain. This time is referred to the time of flight. And the time of flight can be calculated with the following expression:

t = √2h/g   (2)

Where g is gravity acceleration which is 9.8 m/s². Replacing the data into the expression we have:

t = √(2*2500)/9.8

t = 22.59 s

Now replacing into (1) we have:

X = 95 * 22.59

This is the distance where the package should be released.

Hope this helps

Answer:

speed = m/s on y axis

time = s on x axis

when you calculate the slope you do y2-y1/x2-x1 right?

m/s/s become \(m/s^2\), which is the unit of acceleration

On a speed vs time graph, if you see that the line is constant, then acceleration = 0 because there is no difference in speed, you are not acceleration or decelerating.

So in summary, it's acceleration

Explanation:

The period on planet X is (2/√3) times the period on Earth. Option A is correct.

The torque of force F1 about the axis through point O is closest to 4.8 N*m. Option B is correct.

The time taken for the mass to reach the floor is approximately 0.580 s. Option E is correct.

The acceleration due to gravity on this planet is 11.4 m/s². Option B is correct.

The period of a simple pendulum is given by the formula T = 2π√(L/g), where L is the length of the pendulum and g is the acceleration due to gravity.

If the acceleration due to gravity on planet X is 3 times that of Earth, then g_X = 3g_E.

Using the formula for the period, we can rewrite it as

T_X = 2π√(L/g_X).

Substituting

g_X = 3g_E,

we get

T_X = 2π√(L/(3g_E)).

Since T_X is the period on planet X and T is the period on Earth, we have

T_X = 2π√(L/(3g_E))

      = 2π√(1/3) * √(L/g_E) = (2/√3)T.

Therefore, the period on planet X is twice as long as the period on Earth. Option A is correct.

Torque is defined as the product of the force applied and the perpendicular distance from the point of rotation. In this case, the torque of force F1 can be calculated as torque = F1 * d1, where d1 is the perpendicular distance from point O to the line of action of F1.

Since the plate is in a horizontal plane and force F1 is acting vertically downward at point A, the perpendicular distance d1 is equal to the length of OA. Therefore, the torque of force F1 about the axis through point O is closest to F1 * OA = 8N * OA. 4.8 Nm is the closest value to 8N*m. Option B is correct.

The time taken by the mass to reach the floor can be calculated using the equation:

h = (1/2)gt²,

where h is the distance fallen, g is the acceleration due to gravity, and t is the time taken.

In this case, the distance fallen is given as 1.50 m, and the acceleration due to gravity can be calculated using the equation:

g = (m * a) / I,

where m is the mass and I is the moment of inertia.

Substituting the given values, we have

g = (40.72 kg * 9.8 m/s²) / 4.00 kg*m²

  = 99.82 m/s².

Now we can rearrange the equation for time as

t = √(2h / g).

Substituting the values for h and g, we get

t = √(2 * 1.50 m / 99.82 m/s²) = 0.580. Option E is correct.

The period of a simple pendulum is given by the formula T = 2π√(L/g), where L is the length of the pendulum and g is the acceleration due to gravity.

Given that the period T is 1.79 s and the length of the pendulum L is 1.00 m, we can rearrange the formula to solve for g.

Squaring both sides of the equation and isolating g,

we have

g = (4π²L²) / T².

Substituting the given values, we get

g = (4π² * (1.00 m)²) / (1.79 s)² = 11.4 m/s². Option B is correct.

The density of matter in a lead nucleus is 2.82 x 10¹⁷ kg/m³.

Lead nucleus is composed of protons and neutrons. The density of a nucleus is the mass of a nucleus divided by the volume occupied by the nucleus. The volume of a nucleus can be determined using the formula

(4/3)πr³,

where r is the radius of the nucleus. As the diameter of a lead nucleus is given as 14.2 fm, the radius of a nucleus can be calculated as follows:

radius = diameter/2

= 14.2 fm/2

= 7.1 fm

Hence, the volume of a lead nucleus can be calculated as:

(4/3)πr³ = (4/3)π(7.1 fm)³

= 1.57 x 10⁻⁴ fm³

As the mass of a lead nucleus is 3.15 x 10⁻²⁵ kg, the density of matter in a lead nucleus can be calculated as follows:

Density = Mass/Volume

= 3.15 x 10⁻²⁵ kg/1.57 x 10⁻⁴ fm³

= 2.82 x 10¹⁷ kg/m³

The density of matter in a lead nucleus is 2.82 x 10¹⁷ kg/m³.

Different wavelengths of light result in various color perceptions. Whereas violet is perceived by the shortest wavelengths, red is perceived by the longest ones.

Frequency and wavelength are two important characteristics of a wave cycle. A further definition of "wavelength" is the distance between any two matching positions on adjacent waves. Frequency is another word for the number of waves that pass through a specific location in a specific amount of time.

The wavelength is the space between successive crests, whereas the frequency is the quantity of crests that impact the beach per second. The only distinction is that we do so when discussing light rather than water.

The period of the pendulum is approximately 2.01 seconds.

The period of a simple pendulum is determined by its length and the acceleration due to gravity. In this case, the length of the pendulum is 0.20 meters.

The period (T) of a pendulum can be calculated using the formula:

T = 2π√(L/g)

where L is the length of the pendulum and g is the acceleration due to gravity.

Substituting the given values into the formula:

T = 2π√(0.20/9.8)

Calculating the expression:

T ≈ 2π√(0.0204)

T ≈ 2π(0.143)

T ≈ 0.902π

T ≈ 2.01 seconds

The normal result of the trade wind blowing from South America to Indonesia and Australia warm water produces rainy weather in Indonesia and Australia. Option D

We know that the trade winds are the winds that tend to originate at the north east or the south eastern parts of the hemisphere and tend to be blowing across the seas towards the equator. Thus we can see that the focus of the trade winds is the equator and they emanate from north or south.

One of the effects of the trade winds is that they make the wind warmer and that would make to the emergence of a warmer weather and this would spread to the other parts of the word as we can see from map studies.

1 newton is equal to approximately 0.225 pounds.

The newton (N) and pound (lb) are both units of force, with the newton being the standard unit in the International System of Units (SI) and the pound being commonly used in the United States and United Kingdom. The conversion between the two units is not straightforward as they are based on different reference points.

However, using the conversion factor of 1 N = 0.225 lb, we can find out that one newton is equivalent to approximately 0.225 pounds. This means that if a force of 1 newton is applied, it would be equivalent to a force of 0.225 pounds.

The particles in Figure 22.46 exhibit signs of both positive and negative charges.

In Figure 22.46, the presence of both positive and negative charges can be inferred based on the observed behavior of the particles. The interaction between charged particles can be explained through the principles of electrostatics. When two particles carry the same type of charge, they repel each other, while particles with opposite charges attract each other.

By observing the behavior of the particles in Figure 22.46, we can identify the signs of their charges. For instance, if two particles move away from each other or repel each other, it indicates that they possess the same charge. This behavior is characteristic of particles with either positive or negative charges.

Conversely, if two particles move closer together or attract each other, it suggests that they possess opposite charges. This behavior is indicative of particles with opposing charges, where one carries a positive charge and the other carries a negative charge.

It's important to note that the exact nature of the charges cannot be determined solely based on the behavior of the particles in Figure 22.46. Further information or experimental data would be required to ascertain whether the charges are positive or negative. Nevertheless, the observed repulsion and attraction between the particles provide clear indications of the presence of both positive and negative charges.

To find the time required for the cheerleader's pom-pom to move from the equilibrium position to a point a distance of 11.2 cm away, we can use the formula for the period of simple harmonic motion (SHM):

T = 1/f

T = 1 / 0.900 Hz

T ≈ 1.111 s

where T is the period and f is the frequency. In this case, the frequency is given as 0.900 Hz.

Plugging in the values:

T = 1 / 0.900 Hz

Calculating the reciprocal of the frequency:

T ≈ 1.111 s

The period represents the time required for one complete cycle of motion. Since we want to find the time for the pom-pom to move from the equilibrium position to a point 11.2 cm away, we can divide the period by 4, as this corresponds to one-fourth of a complete cycle.

Time required = T / 4

Time required ≈ 1.111 s / 4 ≈ 0.2778 s
