How could you reorganize Table 2-2 so that the data would be more useful?

1 answer:

3 0

First, I would make a copy of Table 2-2 with some color of ink
that's visible, to replace the current one printed in invisible ink.

That change would immediately make the whole table more useful,
and I could go ahead and think about how to reorganize the data.

A 10-N force is needed to move an object with a constant velocity of 5.0 m/s. What power must be delivered to the object by the

vagabundo [1.1K]

The power that must be delivered to the object by the force is 50 W

Power is defined as the rate of doing work. The power of an object in relation to the force and velocity is given by the following equation:

Power (P) = Force (F) × velocity (v)

P = F × v

From the question given above, the following data were obtained:

Force (F) = 10 N
Velocity (v) = 5 m/s
Power (P) =?

P = F × v

P = 10 × 5

Thus, the power that must be delivered to the object by the force is 50 W

A particle with a charge of 3.00 elementary charges moves through a potential difference of 4.50 volts. What is the change in el

GuDViN [60]

Answer:

$7.2\cdot 10^{-19} J$

Explanation:

The change in electrical potential energy of a charged particle moving through a potential difference is given by

$\Delta U = q \Delta V$

where

q is the magnitude of the charge of the particle

$\Delta V$ is the potential difference

In this problem:

- the charge of the particle is 3.00 elementary charges, so

$q=3e=3\cdot 1.6\cdot 10^{-19} J=4.8\cdot 10^{-19}J$

- the potential difference is

$\Delta V=4.50 V$

So, the change in electrical potential energy is

$\Delta U=(1.6\cdot 10^{-19}C)(4.50 V)=7.2\cdot 10^{-19} J$

Describe the heliocentric model of the universe

drek231 [11]

<span>The heliocentric model of the universe was proposed by Nicolaus Copernicus. There are numerous scientist in ancient times who try to explain what happens in the universe. He may not be the first one who proposed that what astronomical body is the center of the universe. However, he stated that the center of the universe was the sun, not the earth. And the earth revolves around it. It is in his book on the Revolutions of the Heavenly Bodies. It was only published as he lay in his deathbed. </span>

puteri [66]

That the field studys the social context in relationships, society, family, school, etc. The way we form relationships, how society affects the relationships we decide to form, how much society influences our decisions, jobs, education( more than we can imagine.)
I believe the most aggravating issue is the police bruality. The fact that the men who are suppose to be heroes, save lives through enforcing the laws, and give protection to the citizens, are instead acting as criminals themselves killing and creating a sense of danger is inexcusable and a solution needs to be made .
