In the box provided explain why living organisms contain more hydrogen atoms than any other atoms

1 answer:

6 0

Answer:it is due to present of water amount in our body. Our body consists 70%of water and 1/3of oxygen and 2/3 of hydrogen.

Explanation: human body consist of 1/3 of oxygen and 2/3 of hydrogen because oxygen contain 16 times more mass than hydrogen atom, hydrogen has only 1 proton so its atomic no. is 1 whereas oxygen has 8 proton and 8 neutrons so its atomic no.is 8 and mass is 16 so overall it takes 16 hydrogen atoms to equal to the mass of 1 oxygen atom.

A box rests on top of a flat bed truck. the box has a mass of m = 18 kg. the coefficient of static friction between the box and

konstantin123 [22]

For this case, the first thing you should do is write the kinematic motion equation of the block.
We have then:
vf = vo + a * t
Where,
vf: Final speed.
vo: Initial speed.
a: acceleration.
t: time.
Substituting the values:
(16) = (0) + a * (16)
Clearing the acceleration:
a = 16/16 = 1m / s ^ 2
Note: the other data for this case are not used in this problem.
answer:
The acceleration of the box is 1m / s ^ 2

True or False. Can Metalloids conduct electricity under certain conditions?

EleoNora [17]

Answer:

Conduction: Some metalloids, such as silicon and germanium, can act as electrical conductors under the right conditions, thus they are called semi-conductors. Luster: Silicon for example appears lustrous, but is not malleable or ductile (it is brittle - a characteristic of some nonmetals).

Ahat [919]

The question is incomplete. The complete question is :

Two loudspeakers are placed 1.8 m apart. They play tones of equal frequency. If you stand 3.0 m in front of the speakers, and exactly between them, you hear a minimum of intensity. As you walk parallel to the plane of the speakers, staying 3.0 m away, the sound intensity increases until reaching a maximum when you are directly in front of one of the speakers. The speed of sound in the room is 340 m/s.

What is the frequency of the sound?

Solution :

Given :

The distance between the two loud speakers, $d = 1.8 \ m$
