Assume upward is the positive direction. Julia tosses a water balloon straight up at time t = 0.The option D of the following graphs best shows the velocity of the ball after it is thrown.

Velocity is a term defines that a particles covered distance upward positively and downward negatively in a constant time. It is a vector quantity.

According to the question, assuming upward is the positive direction. Julia tosses a water balloon straight up so there is a initial velocity in the balloon.

So the curve starts from the positive vertical axis of v-t curve.

we are using the formula; v=u+at

Now we know from discussion, there is a positive initial velocity. But There is a acting of acceleration due to gravity. That acceleration acting the on ball from the beginning. So after some time the velocity of the ball become zero and then it start to moving downwards.

Then the formula becomes,

v=u+(-a)t

Or, v=u-at

So, from the above discussion we can say that the nature of graph (d) is similar to our discussion. The option D of the following graphs best shows the velocity of the ball after it is thrown.

When earth catches up to a slower-moving outer planet and passes it in its orbit, in the same way that a faster runner overtakes a slower runner in an outside lane, the outer planet exhibits a retrograde motion

When a planet is far from another planet and observed from it, it rotates at a slower rate, making it appear that it is "retrograding" with regard to the other planet.

Early astronomers were perplexed when they observed motion in the sky because they attempted to explain it in terms of the geocentric idea.

Due to their commitment to the geocentrical paradigm, which stated the Earth was the center of the solar system, early astronomers were perplexed and unable to explain the phenomena.

By transition energy, the emission of less energy in the h atom is an electron moving from n = 4 to n = 2.

We need to know about transition energy to solve this problem. Electrons in a hydrogen atom can move to another level of energy. It is also called a transition. In this process, electrons will absorb or release their energy to move. The transition energy can be determined as

ΔE = E2 - E1

where ΔE is transition energy, E2 is the final state of energy and E1 is the initial state of energy.

The state energy of a hydrogen atom can be calculated by

E = -(13.6) / n² eV

E = h.c / λ

where n is the number of energy states, h is Planck constant (4.136 x 10¯¹⁵ eV/Hz), c is speed of light (3 x 10⁸ m/s) and λ is wavelength.

From the question above, we know that

ΔE1 from n =4 to n = 2

ΔE1 from n =3 to n = 2

From the equation, we know that the transition energy is depends on the level state where

ΔE ~ (1/n2² - 1/n1²)

Hence

ΔE1 / ΔE2 = (1/n2² - 1/n1²) / (1/n2² - 1/n1²)

ΔE1 / ΔE2 = (1/2² - 1/4²) / (1/2² - 1/3²)

ΔE1 / ΔE2 = (3/16) / (5/36)

ΔE1 / ΔE2 = (3/16) / (5/36)

ΔE1 / ΔE2 = 1.35

ΔE1 = 1.35 ΔE2

Hence, the emission of less energy in the h atom is an electron moving from n = 4 to n = 2.

By using uniform motion, with an initial speed 25.43 m/s and 2.60 seconds the ball will rise maximum height.

We need to know about the uniform motion to solve this problem. The uniform motion is an object's motion under acceleration. It should follow the rule

vt = vo + a . t

vt² = vo² + 2a . s

s = vo . t + 1/2 . a . t²

where vt is final velocity, vo is initial velocity, a is acceleration, t is time and s is displacement.

From the question above, we know that

h = 33m

vt = 0 m/s

g = 9.8 m/s²

The gravitational acceleration will be negative, hence

vt² = vo² - 2g . h

0² = vo² - 2. 9.8 . 33

vo² = 646.8

vo = √646.8

vo = 25.43 m/s

Use the first equation to get the time taken

vt = vo - g . t

0 = 25.43 - 9.8t

9.8t = 25.43

t = 2.60 second

Answer:

C. is correct.

Explanation:

Hope this helps :)

The suggestion given by Hannah is not a well-supported and widely accepted explanation. So, option A is correct.

Friction is a force that prevents two solid objects from rolling or sliding over one another. Although frictional forces, such as the traction required to walk without slipping, may be advantageous, they can provide a significant amount of resistance to motion. Automobile engines use about 20% of their output to overcome frictional forces in moving parts.

The adhesion forces between the contact zones of the surfaces, which are always microscopically uneven, appear to be the primary cause of friction between metals. Shearing these "welded" joints and the action of the tougher surface's imperfections scrubbing against the softer surface cause friction.

According to the question, Hannah is driving the car up a hill and when she is not pressing the accelerator the car slows down. The reason behind this is that there is an ascent of height that the car has to climb with its engine power and if the accelerator is not applied to it then it will start to slow down also friction is a factor that is involved in this case.

The maximum velocity is v= √10gh/7

The energy that an object has due to its location in a gravitational field is known as gravitational potential energy. When an object is close to the surface of the Earth, when the gravitational acceleration can be assumed to remain constant at roughly 9.8 m/s2, gravitational potential energy is most frequently used.

For the situation of the maximum velocity of the sphere when it hits the ground, the loss in gravitational potential energy is equal to the gain in translational kinetic energy and rotational kinetic energy.

mgh = mv² x I / 2.

mgh = 0.5 mv² + 0.5 (2/5 mR²)

The no-slip condition results in:

v=Rω

mgh = 0.5 mv + 0.2 mv

Force causes an object to come to rest when it accelerates and causes a body to accelerate when it is at rest. Force is therefore the result of mass times acceleration. The overall force applied on a body is known as the net force. The total of all forces exerted on an object is known as the net force. There are two different types of forces: balanced forces and imbalanced forces. The term "balanced force" refers to an object that is balanced on both of its sides. Unbalanced force is defined as the movement of an item caused by an excessive force applied to one side.

Force exerted by Kam = 5N

Force exerted by Jaylan = 8N

At 65.7K temperature is the resistance 2 ohms.

A conductor's resistance is influenced by its temperature, and a conductor's initial resistance and temperature change are directly inversely correlated. It has been noted that a conductor's resistance increases as temperature rises.

i.e., ΔR ∝ R₀ΔT

R is the temperature coefficient of resistance and T is the temperature.

⇒ R - R₀ =R₀αΔT

⇒ R = R₀(1 + αΔT)

R0 = starting resistance in this case = 1.25

0.00375°C is the temperature coefficient.

2 = 1.25[1 + 0.00375(0-[tex]T_{f}[/tex])]

2 = 1.25 + 1.25× 0.00375(0-[tex]T_{f}[/tex])

0.75 = 0.0046875(0-[tex]T_{f}[/tex])

What is Electric Potential Energy?

The amount of work required to move one charge from infinity to a location close to the other charge is known as the electric potential energy of a system of two charged particles. When two charges exist in a system and are separated by an infinite distance, their electric potential energy is zero. The following mathematical formula can be used to express the electric potential energy of a system of two charged particles:

U =k⋅q1⋅q2/r

Where:

k is the coulomb's constant.

q1 is one of the charges.

q2 is the second charge.

initial speed of  electron u = 0 m/s

mass of an electron is m= 9.11×10^−31 kg

Let v be the final velocity of the electron

When the electron is quite distant from the fixed charge, we are asked to determine its final speed. The system is being held together by a conservative force (electron and fixed charge) (electric force). As a result, we can apply the principle of mechanical energy conservation by equating the system's beginning mechanical energy (represented by the electron and constant charge) to the system's ultimate mechanical energy as follows:

MEi = MEf

KEi + PEi = KEf + PEf
