Answer:

True

Explanation:

Gravity is a force that helps to hold the universe together. The statement is true. The gravitational force is always attractive in nature. It depends on the masses and the distance between them. Mathematically, it is given by :

F=G\dfrac{m_1m_2}{d^2}

Where

G = universal gravitational constant

m₁ and m₂ are masses

d is the distance between them

Gravity is responsible to hold the planets in an orbit around the sun. Ocean tides are also caused due to gravitational pull of the moon. If gravity is not present in the universe then there would be no moon, no stars etc.

Hence, the given statement is true.

Energy travels at right angles to the direction of the vibrating particles in ________ waves.

Energy travels at right angles to the direction of the vibrating particles in Transverse waves

<h3>What is a transverse wave oceanography?</h3>

Energy can flow from one spot to another in a wave phenomenon, but the particles of matter in the medium return to their fixed position. A wave transmits energy without moving mass. Although waves can be observed moving through an ocean or lake, the water always returns to its resting place. The medium's particles just vibrate in situ. As they vibrate, the energy of the disturbance is passed on to the particles next to them, who then pass it on to the particles next to them, and so on.

Transverse waves can only go through solids, but longitudinal waves can travel through solids, liquids, and gases.

Transverse waves cause the medium to travel perpendicular to the wave's direction.

If the intensity level by 15 identical engines in a garage is 100 dB, what is the intensity level generated by each one of these
goblinko [34]

To develop this problem we will apply the concepts related to Sound Intensity. This can be defined as the power carried by sound waves per unit area in a direction perpendicular to that area. Mathematically it can be written as,

\Delta L = 10log(n)

\Delta L = Level Difference

n = Number of equal loud sound sources

n = 15

Therefore replacing we have,

\Delta L = 10 log (n)\\\Delta L = 10 log (15)\\\Delta L = 10*1.176\\\Delta L = 11.76dB

Therefore over 100dB the total difference intensity level would be

L_T = L_0 -\Delta L

Here,

L_0 = \text{ Total intensity}

\L_T = 100 -11.76

_T= 88.24dB

The intensity level generated by one engine is

L_T = 88.44dB

Ozone is bad for the Earth and one of the causes of Global Warming?
boyakko [2]

Answer:

The outer Ozone is helpful. Ozone occurs in two layers of the atmosphere. The layer closest to the earth's surface is called the troposphere; ground-level or (bad) ozone is an air pollutant that is harmful to breathe and it damages crops, trees and other vegetation. It is a main ingredient of urban smog.
