A 3.00 kg toy falls from a height of 10.0 m. Just before hitting the ground, what will its kinetic energy be?

Answers

Answer:

294 J

Explanation:

To find the kinetic energy (KE) of a 3.00 kg toy falling from a height of 10.0 m, we'll use the kinetic energy formula: KE = 0.5 * m * v^2, where 'm' is the mass of the toy, and 'v' is its velocity.

We'll also apply the conservation of energy principle, which states that the total energy of an isolated system remains constant. This means that the gravitational potential energy (PE) of the toy at the initial height is equal to its kinetic energy just before hitting the ground.

The formula for gravitational potential energy is PE = m * g * h, where 'm' is the mass of the object, 'g' is the acceleration due to gravity, and 'h' is the height of the object.

So, we can equate these two expressions and solve for 'v':

0.5 * m * v^2 = m * g * h

v^2 = 2 * g * h

v = √(2 * g * h)

Plugging in the given values:

v = √(2 * 9.8 m/s² * 10.0 m)

v ≈ 14.0 m/s

Now that we have the velocity of the toy, we can calculate its kinetic energy using the KE formula:

KE = 0.5 * m * v^2

KE = 0.5 * 3.00 kg * (14.0 m/s)^2

KE ≈ 294 J

So, just before hitting the ground, the kinetic energy of the toy is approximately 294 joules.

In a transverse wave ,if you increase of the wave you will get what kind of wavelength

Answers

using the formula v = f λ, 
where v is the velocity of the wave, f is the frequency of the wave and λ is the wavelength of the wave. 

assuming that the velocity of the wave remains constant, by increasing the wavelength the frequency must decrease.

When looking at human motives the following theorist developed a hierarchy of five needs that range from basic physiological needs to groeth or meta-needs

Answers

The theorist you are talking about is none other than Abraham Maslow. He developed the Maslow's hierarchy of needs wherein basic human needs range from the physiological, security, and love and belongingness needs to the esteem and self-actualization of the individual. 
Abraham Maslow proposed Maslow's Hierarchy of Needs in 1943. His paper, "A Theory of Human Motivation" presented the idea that the most basic needs such as food were at the base of the hierarchy and must therefor be met before the higher levels of needs such as safety, love, esteem, and self-actualization.

'When we see something that exists in real life, there are many different ways to display imagery and importance using art. What the artist _____________ depends on what he/she wants to communicate.'

Answers

Answer:

Emphasizes

Explanation:

The expression of an art is intelligible to those that understand it, as such to make an impression an artist has to emphasize the point they want to communicate

An art is an expression of the personal experiences of the artist or a reaction to events or to reveal the realities as seen by the artist such as global warming and the environment, so as to get the attention of people with the goal to change them, such that a good art changes the most people, hence the need for emphasis.

Answer:

A - emphasizes
