TRUE OR FALSE: with time and pressure, peat turns into lignite, or brown coal.

It is an important part of many cells and processes such as amino acids, proteins and even our DNA. It is also needed to make chlorophyll in plants, which is used in photosynthesis to make their food.

Hope this helps! ;)

Solution:

Step wise solution

Let r1 be the distance from the Earth to the point where

the gravitational accelerations are the same and let r2 be the distance

from the Moon to that point.

Then, r1+ r2 = r12 = 383,000 km.

Let Re be the radius of earth

and let Rm be the radius of moon

Let, ge be the gravity of earth

and let gm be the gravity of moon

The fact that the gravitational attractions by the Earth and the Moon

at this point are equal leads to the equation

gE(Re/r1)=gM(Rm/r2)

9.8(6380/r1)=1.62(1738/r12-r1)              

(here, Re=6380, gE=9.8m/s^2,  gM=1.62m/s^2 and r12=383,000 km

9.8*6380/(1.62*1738)=r1/(383000-r1)

therefore,

r1=344,770 km

Hope this answer wil help you

Answer:

                Option-A " The intermolecular forces holding the caffeine molecules together are weaker than the ionic bonds in CuCl₂ ".

Explanation:

                         There are two types of interactions among the atoms and molecules. One are known as intramolecular forces while the other are known as intermolecular forces.

Examples of Intramolecular forces are ionic bonds and covalent bonds e.t.c. while examples of intermolecular forces are hydrogen bond interactions, dipole-dipole interactions e.t.c.

Remember that intramolecular forces ar far more greater in strength than the intermolecular forces. Hence, in given statement the interactions between Caffeine molecules are intermolecular forces while, that between Cu and Cl ions in CuCl₂ are intramolecular forces.

Explanation: A chemical property of iron is that it is capable of combining with oxygen to form iron oxide, the chemical name of rust. The more general term for rusting and other similar processes is corrosion.

Answer:

capable of combining with oxygen and becoming iron oxide

Final answer:

Newton's laws of motion can be applied in a car crash to explain the physics and forces involved.

Explanation:

In a car crash, Newton's laws of motion can be applied in several ways:

1. Newton's first law: Also known as the law of inertia, this law states that an object at rest tends to stay at rest, and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an external force. In a car crash, the body of the occupants tends to stay in motion until acted upon by a force, such as the seatbelt or the airbag.
2. Newton's second law: This law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. In a car crash, the greater the force of impact, the greater the acceleration experienced by the occupants. This is why it is important to wear seatbelts and have properly functioning airbags.
3. Newton's third law: This law states that for every action, there is an equal and opposite reaction. In a car crash, when two vehicles collide, the force exerted by one vehicle on the other is met with an equal and opposite force.

Overall, Newton's laws of motion help explain the physics behind car crashes and the forces involved.
