What is the best description of the relationship between emerging scientific ideas and open-mindedness?

Given the necessary information about the two components of projectile motion, your task is to explain the difference or even de

ivann1987 [24]

The two components of projectile motion include the following:

Horizontal motion

Vertical motion.

<h3>What is a Projectile?</h3>

This is defined as a missile propelled by the application of an external force and allowed to move freely under the influence of gravity and air resistance.

The equation for Horizontal motion Vx = V * cos(α)

Vertical velocity component: Vy = V * sin(α)

How long does it take the moon to go through an entire set of phases?.

Bas_tet [7]

It take <u>approximately 29</u><u>.</u><u>5 </u><u>days</u> for moon to do its entire set of phases.

<h3>Explanation</h3>

The Moon is the only natural satellite of the Earth which undergoes three motions, that is :

Rotating on its own axis
Evolving around the Earth
Together with the Earth evolving around the sun as the center of the solar system

With that, the moon has two periods of revolution, namely:

Sidereal revolution, which is the original revolution of the Moon. This sidereal revolution is really the time it takes the Moon to orbit the Earth. The sidereal revolution of the moon has a time span of <u>27.3 days</u> or more accurate is approximately 27 days, 7.72 hours.
Synodic revolution, namely the revolution of the Moon as seen from Earth as a series of moon phases (from the new moon phase, to the next new moon phase). The synodic revolution is slower, because the Moon needs to catch up with the Earth rotating in the same direction as the Moon. The synodic revolution of the moon has a time span of 29.5 days or to be more accurate approx 29 days, 12.734 hours.

A small sphere is hung by a string from the ceiling of a van. When the van is stationary, the sphere hangs vertically. However,

olganol [36]

Answer with Explanation:

We are given that

String makes an angle w.r.t vertical= $\theta=$

a.We have to derive an expression for the magnitude of the acceleration of the van in terms of the angle $\theta$ and magnitude g of the acceleration due to gravity.

According to newton's second law

$T sin\theta=ma$

$Tcos\theta=mg$

$\frac{Tsin\theta}{Tcos\theta}=\frac{ma}{mg}$

$tan\theta=\frac{a}{g}$

$a=gtan\theta$

b. $\theta=10^{\circ}$

$g=9.8 m/s^2$

$a=9.8\times tan10^{\circ}=1.73 m/s^2$

c.Velocity=Constant

We have to find the angle $\theta$

$a=0$

$0=9.8tan\theta$

$tan\theta=0$

$tan\theta=tan0$

$\theta=0^{\circ}$

EXPERIMENT:ELECRIC MOTOR.

g100num [7]

Answer:

1. Current flows through the battery, aluminum foil, and paper clips, and into the wire coil, creating an electromagnet. One face of the coil becomes a north pole; the other a south pole. The permanent magnet attracts its opposite pole on the coil and repels its like pole, causing the coil to spin.

- Quoted from Google

2. Electrical engineers say that, in an electrical circuit, electricity flows one direction: out of the positive terminal of a battery and back into the negative terminal. Electronic technicians say that electricity flows the other direction: out of the negative terminal of a battery and back into the positive terminal.
