The ball continues to fall, its kinetic energy will increase.

Kinetic energy is the energy an object possesses due to its motion. It is the energy associated with an object’s speed and mass, and is the energy that an object has because of its movement. Kinetic energy can be converted into other forms of energy, such as heat, light, or sound. It can also be used to do work, such as moving objects or powering machines. Kinetic energy is a form of mechanical energy, which is energy that is associated with the motion or position of an object. Kinetic energy is related to the work done on an object, and it increases as the object’s speed increases. Kinetic energy can be calculated using the formula KE = ½mv2, where m is the mass of the object and v is the velocity of the object.

The kinetic energy of the ball will increase as it falls, because it is gaining speed due to gravity.
As it falls, it accelerates at a rate of 9.8 m/s^2, and its kinetic energy is equal to its mass multiplied by the square of its velocity.
Therefore, as the ball continues to fall, its kinetic energy will increase.

Using t=0 s as the time the stone leaves the thrower's hand at position, determine the time at which the stone reaches its maximum height: When the stone reaches its maximum height, its vertical velocity becomes zero.

Therefore, the time when the stone reaches its maximum height can be found using the following kinematic equation: v = u + at Where v = 0 (since the vertical velocity becomes zero at the maximum height), u = 20 m/s, a = -9.81 m/s² (negative since it acts in the opposite direction to the initial velocity), and t is the time taken to reach the maximum height. Therefore, t = (v - u) / a= (0 - 20) / -9.81 = 2.04 s Hence, the time at which the stone reaches its maximum height is 2.04 s.2.

Find the maximum height of the stone: To find the maximum height of the stone, we need to use the following kinematic equation: h = u*t + (1/2)*a*t²Here, h is the maximum height, u = 20 m/s, a = -9.81 m/s², and t = 2.04 s (time taken to reach the maximum height).

Therefore, h = 20*2.04 + (1/2)*(-9.81)*(2.04)²= 20.4 m Hence, the maximum height of the stone is 20.4 m.3. Determine the velocity of the stone when it returns to the height from which it was thrown: The stone is launched upwards with an initial velocity of 20 m/s.

Three charges, each equal to Q, are placed at the three corners of a square of side b. The electric field at the fourth corner is 4kQ/b2.

Three charges Q are placed at three corners of a square as shown above, and the electric field at the fourth corner is required. As there are 3 charges with the same magnitude and same distance from the fourth corner, they produce electric fields, which are equal in magnitude and direction, at the fourth corner.

Let’s find the electric field at the fourth corner using Coulomb's law which is expressed as:

\(\[E = \frac{kQ}{r^2}\]\)

Where, Q is the charge, k is the Coulomb’s constant, r is the distance between the charges

Considering the electric field produced by the charge at the bottom left corner at the fourth corner E1.

As the charge is placed on the diagonal, the perpendicular distance from the charge to the fourth corner is

\(\[r = \frac{b}{\sqrt 2 }\]\)

Using Coulomb's law, we can write the electric field produced by this charge as:

E1 = kQ/b2/2 = 2kQ/b2

We can write the electric field produced by the charge at the top left corner at the fourth corner E2, as:

E2 = kQ/b2

Using the same logic as before, we can write the electric field produced by the charge at the bottom right corner at the fourth corner E3, as:

E3 = kQ/b2

Since the electric field produced by these three charges will be in the same direction, the net electric field at the fourth corner will be the vector sum of the three electric fields calculated above.

Thus,E4 = E1 + E2 + E3 E4 = 2kQ/b2 + kQ/b2 + kQ/b2 E4 = 4kQ/b2

The electric field at the fourth corner is 4kQ/b2.

The power of the camera lens with a 50.0 mm focal length is approximately 20 diopters.

In optics, the power of a lens is a fundamental characteristic that determines its ability to converge or diverge light rays.

In the case of a camera lens with a focal length of 50.0 mm, we can calculate its power, which provides insights into its optical properties and its suitability for capturing images.

The power of a lens, P, in diopters (D), is given by the formula:

\(P = \frac{1}{f}\)

where f is the focal length of the lens.

Using the given focal length of 50.0 mm, we can calculate the power as:

\(P = \frac{1}{50.0 \, \text{mm}}\)

Converting millimeters to meters (1 mm = 0.001 m), we have:

\(P = \frac{1}{50.0 \, \text{mm} \times 0.001 \, \text{m/mm}}\)

Simplifying, we get:

\(P = \frac{1}{0.05 \, \text{m}}\)

Calculating the reciprocal, we find:

P ≈ 20 D

Therefore, With a 50.0 mm focal length, the camera lens's power is roughly 20 diopters.

The gravity inside the black hole is much greater and hence, no force can overcome it and the spaceship was completely collapsed.

A black hole is a region in space where gravitational force is much stronger, that attracts all the objects even light couldn't escape from it. The general theory of relativity predicts the presence of a black hole. The black hole is formed by the collapse of massive stars. It is also formed by the gradual accretion of mass of millions or billions of stars.

The black hole has two important parts and they are an event horizon and singularity. The event horizon is the outer layer of the black hole and the singularity is at the center of the black hole and it has high gravitational force.

A stretched spring : Elastic potential energy

Muscle of the athlete : Chemical energy

Explanation:

Elastic potential energy is the form of energy stored in an Elastic object(Can stretch and relax), when it is deformed from it's original shape.

The acceleration of the system is equal to the sum of the external force (F) plus 190 N, divided by the total mass of the three boxes (150.0 kg).

Acceleration is a type of motion in which the velocity of an object changes over time. It is the rate of change of the velocity of an object with respect to time. Acceleration is the derivative of velocity with respect to time which can be calculated by dividing the change in velocity by the change in time. Acceleration can be positive, negative, or zero. Positive acceleration is when an object is speeding up and negative acceleration is when an object is slowing down or reversing direction.

The acceleration of the system can be calculated using Newton's Second Law of Motion, which states that the net force (Fnet) acting on an object is equal to the mass (m) of the object multiplied by its acceleration (a):

Fnet = ma

In this case, the net force acting on the system of boxes is the external force (F) pushing on box A plus the force that box B exerts on box C (190 N). Therefore, the net force is F + 190 N = Fnet.

Using Newton's Second Law, we can calculate the acceleration of the system as follows:

Fnet = ma

(F + 190 N) = (30.0 kg + 45.0 kg + 75.0 kg)a

F + 190 N = 150.0 kga

a = (F + 190 N) / 150.0 kg

Therefore, the acceleration of the system is equal to the sum of the external force (F) plus 190 N, divided by the total mass of the three boxes (150.0 kg).

According to Coulomb, the electric force for charges at rest has the following properties: Like charges repel each other; unlike charges attract. Thus, two negative charges repel one another, while a positive charge attracts a negative charge. The attraction or repulsion acts along the line between the two charges.

Things that are negatively charged and things that are positively charged pull on (attract) each other. This makes electrons and protons stick together to form atoms. Things that have the same charge push each other away (they repel each other). This is called the Law of Charges.

The total energy of the system is 0.4 Joules.

To find the total energy of the system, we first need to determine the amplitude (A) and angular frequency (ω) of the simple harmonic motion. From the given equation, x = (0.20m)sin[(2π/2.0s)t], we can see that A = 0.20m and ω = (2π/2.0s).

The total energy of a system undergoing simple harmonic motion can be found using the formula E = (1/2)kA², where k is the spring constant. We can determine k from ω using the formula ω = √(k/m), where m is the mass of the cart. Plugging in the values, k = ω²m = (2π/2.0s)²(2.0 kg) = 39.478 N/m.

It would take approximately 2.4688 × 10^17 seconds or 7.82 million years for gas to travel from the core of the galaxy to the end of the jet, assuming a constant speed of 5000 km/s.

To calculate the time it would take for gas to travel from the core of the galaxy to the end of the jet, we need to use the formula: time = distance / speed.

Given that the jet in NGC 5128 is traveling at 5000 km/s and is 40 kpc (kiloparsecs) long, we first need to convert the distance from kpc to km. 1 kpc = 3.086 × 10^16 meters, which means 1 kpc = 3.086 × 10^19 km.

Therefore, the length of the jet in kilometers is 40 x 3.086 × 10^19 km = 1.2344 × 10^21 km.

Now we can calculate the time it would take for gas to travel from the core of the galaxy to the end of the jet as follows:

time = distance / speed
time = 1.2344 × 10^21 km / 5000 km/s
time = 2.4688 × 10^17 seconds

So, it would take approximately 2.4688 × 10^17 seconds or 7.82 million years for gas to travel from the core of the galaxy to the end of the jet, assuming a constant speed of 5000 km/s.
