How can you tell animal and plant cells apart

Answers

Answer 1

Answer: Well there are a couple ways. 1: The easiest, plant cells have a cell wall or extra protection. You will not find this on an animal cell, as there is only a membrane. 2: Chloroplast. This also will not be found in animal cells as they produce the plant's green color as well as the sugar. Hope this helps!

What is the relationship between globular clusters and the milky way?

Answers

Globular clusters are nearly spherical groups of about 10,000 to 1 million stars. A typical galaxy may contain up to a few hundred globular clusters; our galaxy, the Milky Way, has somewhere between 125 and 200 globular clusters orbiting the galactic center.

What does the doppler effect indicate about the motion of galaxies?

Answers

When galaxies move farther away the wavelength of the light is longer causing the galaxy to shift red but if it moves closer, the wavelength of the light gets smaller causing the galaxy to blue shift. The reason that the wavelength increases or decrease is due to the doppler effect.

How did locke's and newton's ideas influence enlightenment intellectuals?

Answers

Here is the answer. How Locke's and Newton's ideas influenced Enlightenment intellectuals by arguing that argued that every person was born with a blank mind. Locke's ideas suggested that people were molded by experiences. On the other hand, Newton believed that the world operated according to natural laws that could be uncovered through systemic investigation. Hope this helps.

The ideas of John Locke and Isaac Newton had a profound influence on Enlightenment intellectuals by shaping their understanding of human nature, society, and the natural world.

Here are some key ways in which Locke's and Newton's ideas influenced Enlightenment thinkers:

1) Empiricism and Tabula Rasa: John Locke's philosophy emphasized empiricism and the concept of the mind as a "tabula rasa" or blank slate. He argued that individuals acquire knowledge through sensory experience and that the mind is not innately filled with ideas.

2) Natural Rights and Social Contract: Locke's ideas on natural rights and the social contract had a significant impact on Enlightenment thinkers. Locke argued that individuals possess certain inherent rights, including life, liberty, and property, which should be protected by a government.

3) Scientific Method and Universal Laws: Isaac Newton's discoveries in physics, particularly his formulation of the laws of motion and universal gravitation, provided a model for the application of reason and the scientific method. Newton's work demonstrated the power of observation, experimentation, and mathematical analysis in understanding the natural world.

4) Enlightenment Optimism and Progress: Both Locke and Newton fostered a sense of optimism and belief in human progress. Locke's emphasis on reason, education, and the perfectibility of individuals influenced Enlightenment thinkers in their pursuit of knowledge and social improvement.

Overall, Locke's emphasis on individual rights, reason, and social contract, combined with Newton's scientific discoveries and methodological rigor, provided Enlightenment intellectuals with a framework for challenging traditional authority, promoting individual freedoms, and pursuing rational explanations for human behavior and societal organization.

a 1.0-kg ball is thrown into the air with an initial velocity of 30. m/s. a. how much kinetic energy does the ball have? b. how much potential energy does the ball have when it reaches the top of its ascent? c. how high into the air did the ball travel?

Answers

a) Kinetic energy of ball is 450J.

A 1kg ball is thrown into the air with an initial velocity of 30m/s. Newtonian physics says thekinetic energy that the ball have is:

( $(1)/(2) )$ ×1 kg× $(30 (m)/(s)) ^(2)$ = 450 J.

In physics, what is kinetic energy?

The energy a thing has as a result of motion is known as kinetic energy. A force must be applied to a thing in order to accelerate it. We must put forth effort in order to apply a force. After the job is finished, energy is transferred to the thing, which then moves at a new, constant speed.

b) Potential energy of ball is 450J

The whole amount of energy will be in the form of potential energy since the ball's kinetic energy will be equal to zero. As a result, when the ball reaches the peak of its climb, its potential energy will be 450 J.

c) 45m high into the air ball travel.

KE at start = GPE at the peak

450 = mgh

450 = (1)(g)(h)

450= (1)(10)(h)

45=h

Therefore, the ball will reach up to a height of 45m.

A rock at the edge of a 200-m high cliff has more potential energy than an equal sized rock at the edge of a 600-m high cliff. True or False

Answers

Answer: The given statement is False.

Explanation:

Potential energy is defined as the energy possessed due to the height of the object.

Mathematically,

$E_p=mgh$

where,

$E_p$ = potential energy of the rock

m = mass of the rock

g = acceleration due to gravity = $9.8m/s^2$

h = height of the cliff from where the rock is thrown

When height of the cliff is 200 m

Putting values in above equation, we get:

$E_p=m* 9.8* 200m\n\nE_p=1960m$

When height of the cliff is 600 m

Putting values in above equation, we get:

$E_p=m* 9.8* 600m\n\nE_p=5880m$

So, $E_p(60m)>E_p(200m)$

Potential energy of the rock at 600-m high cliff is more than the potential energy of the rock at 200-m high cliff

Hence, the given statement is False.

It is false. The higher an object is the more potential energy they have.
