if you count 20 beetles in a garden measuring 5 square meters,the population density of the beetles is

Physics

Population density  =  Number of beetles / Unit Square Area

                             =  20 beetles / 5m²  =  4 beetles per m²

Un movil de masa 12Kg sobre el cual estan actuando varias fuerzas F_1=48N, F_2=60N y F_3=30N Calcular la aceleracion con la cual
Nikitich [7]

Answer:

Lamentablemente el problema está incompleto, pues no sabemos la dirección en la que se aplican las fuerzas. Por ello, voy a resolver el problema asumiendo dos casos. (abajo se puede ver una imagen donde se describe cada caso)

1) Todas las fuerzas están en la misma dirección.

Entonces la fuerza neta será la suma de las 3 fuerzas, entonces:

F = 48N + 60N + 30N = 138N

Y por la segunda ley de Newton sabemos que:

F = m*a

fuerza igual a masa por aceleración.

Entonces la aceleración está dada por:

a = F/m = 138N/12kg = 11.5 m/s^2

2) Segundo caso, suponemos que F1 es opuesta a F2 y F3

En este caso, la fuerza neta será:

F = F2 + F3 - F1 = 60N + 30N - 48N = 42N

En este caso, la aceleración será:

a = 42N/12kg = 3.5 m/s^2

What's the difference between beam balance and spring balance?
seropon [69]
<span>A spring balance will give a different mass reading on the Moon from that on Earth. A beam balance however, will give the same reading.Explain why.

</span>


<span>Beam Balance:

Beam balance measures mass.

Mass is the amount of matter the object has.

The S.I. unit of mass is kg


</span><span>
Spring Balance:

Spring balance measures weight not mass.

Disadvantage: It requires gravity to measure.

The S.I. unit of weight is newton (N).

That is why when we are in outer space, we become lighter-there is less gravity!</span>

Mass remains constant while weight is dependent on the gravitational pull of the planet. Mass only changes with a change in matter that results in a change of volume.


<span>Mass remains constant throughout. Only weight changes with gravitational acceleration. Mass will only change with a change in the volume of matter in the body.</span>
