mars1129 [50]2 years ago
6 0

Answer:

<h2>18 N</h2>

Explanation:

The force acting on an object given it's mass and acceleration can be found by using the formula

force = mass × acceleration

From the question we have

force = 6 × 3

We have the final answer as

<h3>18 N</h3>

Hope this helps you

What happens to the negative charges
Nikitich [7]

Answer:

<em>The correct option is C) spreads out over a large area on the object. </em>

Explanation:

In physics, a ground can be described as a reservoir object in which charge can be stored. Grounding refers to the removal of charge in an object by using the ground object. When an object with excess if charge is placed on the ground object, the electrons are transferred from the charges object to the ground object. This charge begins to spread evenly in the ground object with the passage of time.

If the mass of 293nv is 293.15 amu and that of 295nv is 295.30 amu , what is the atomic weight of nv?
expeople1 [14]
Honestly, I am quite confused with what Nv stands for because there is no element with that symbol. However, I still get the concept of finding the average molecular mass of an element. Let's just assume that nv stands for a specific type of element and it has two isotopes: nv-293 and nv-295. Isotopes have the same number of protons but differ in mass number (protons+neutrons). 

To find the average atomic weight, just multiply the individual weights with the respective composition of the isotope. Since there are only two isotopes, they constitute 50% each. So, the average atomic weight is 

(50%)(293.15 amu) + (50%)(<span>295.30 amu) = 294.225 amu

Hence, the atomic weight of nv is 294.225 atomic mass units.</span>

The Force Of Gravity Acting On A Childs Mass On Earth Is 490 newtons whats the childs mass
Flauer [41]
Force of gravity on an object is the weight of the object and is given by mass times accerelation due to gravity. The accerelation due to gravity is the accerelation of an object in free fall and is given by 9.8m/s^2. Given that the force of gravity acting on a child's mass on earth is 490 newtns, i.e. F = mg which means that 490 newtons = 9.8 times mass. Therefore, mass of the child is 490 / 9.8 = 50 kg.

PLZ HELP ME!!!!!!!!
mote1985 [20]

Answer:

1.     Frequency = speed / wavelength

here we know

speed = 343 m/s

wavelength = 0.77955 m

now frequency is given by  

f = \frac{343m/s}{ 0.77955m}

f = 440 Hz  

2.     Frequency = speed / wavelength

here we know

speed = 343 m/s

wavelength = 0.52028 m

now frequency is given by  

f = \frac{343m/s}{ 0.52028m}

f = 659.3 Hz

3.     Frequency = speed / wavelength

here we know

speed = 343 m/s

wavelength = 0.65552 m

now frequency is given by  

f = \frac{343m/s}{ 0.65552m}

f = 523.25 Hz  

4.     Wavelength = speed / Frequency

here we know

speed = 343 m/s

Frequency = 587.33 Hz

now wavelength is given by  

\lambda = \frac{343m/s}{587.33}

\lambda = 0.584 m    

5.     Wavelength = speed / Frequency

here we know

speed = 343 m/s

Frequency = 493.88 Hz

now wavelength is given by  

\lambda = \frac{343m/s}{493.88}

\lambda = 0.6945 m    

6.     Wavelength = speed / Frequency

here we know

speed = 343 m/s

Frequency = 698.46 Hz

now wavelength is given by  

\lambda = \frac{343m/s}{698.46}

\lambda = 0.491 m    

7.     Frequency = speed / wavelength

here we know

speed = 343 m/s

wavelength = 0.5840 m

now frequency is given by  

f = \frac{343m/s}{0.5840m}

f = 587.3 Hz  

8.     Frequency = speed / wavelength

here we know

speed = 343 m/s

wavelength = 0.4375 m

now frequency is given by  

f = \frac{343m/s}{0.4375m}

f = 784 Hz  

9.     Wavelength = speed / Frequency

here we know

speed = 343 m/s

Frequency = 783.99 Hz

now wavelength is given by  

\lambda = \frac{343m/s}{783.99}

\lambda = 0.4375 m    

10.  Wavelength = speed / Frequency

here we know

speed = 343 m/s

Frequency = 659.26 Hz

now wavelength is given by  

\lambda = \frac{343m/s}{659.26}

\lambda = 0.520 m
