Answer:

Move in the same direction as the stronger force.

Explanation:

When a force is applied on an object, it may be balanced force or unbalanced force.

In case of unbalanced forces, the object move in a particular direction. The net force acting on the object is not equal to 0. We know that Newton's second law of motion gives the magnitude of force.

So, when a moving object is acted on by unbalanced forces, the object will move in the same direction as the stronger force.

when there is unbalanced force on the object, there is net force acting on the object. we know from newton's second law which says that net force acting on an object is the product of mass and acceleration of the object. we also know that net force is always in the direction of stronger force and so is the acceleration of the object.

hence the correct choice is

C) move in the same direction as the stronger force.

if a sample known to be about 10,740 years old has 400 carbon-14 atoms. how many atoms were in the sample when the organism dies

GrogVix [38]

Answer:

Carbon 14 has a half-life of about 5740 years

Since this is about 2 half-lives then 1/4 of the atoms would remain

meaning 1600 atoms were initially present , I assume that they mean the sample died 10,740 years ago

More accurately (T / 5740) = n = number of elapsed half-lives

(10740 / 5740) = 1.87 half lives

(1/2)^1.87 = .273 of original amount left

400 / .273 = 1463 atoms originally present

You set a tuning fork into vibration at a frequency of 723 Hz and then drop it off the roof of the Physics building where the ac

zaharov [31]

Answer:

Explanation:

Given

Original Frequency $f=723\ Hz$

apparent Frequency $f'=697\ Hz$

There is change in frequency whenever source move relative to the observer.

From Doppler effect we can write as

$f'=f\cdot \frac{v-v_o}{v+v_s}$

where

$f'=$ apparent frequency

v=velocity of sound in the given media

$v_s=$ velocity of source

$v_0=$ velocity of observer

here $v_0=0$

$697=723\cdot (\frac{343-0}{343+v_s})$

$v_s=(\frac{f}{f'}-1)v$

$v_s=(\frac{723}{697}-1)\cdot 343$

$v_s=12.79\approx 12.8\ m/s$

i.e.fork acquired a velocity of $12.8 m/s$

distance traveled by fork is given by

$v^2-u^2=2as$

where v=final velocity

u=initial velocity

a=acceleration

s=displacement

$v_s^2-0=2\times 9.8\times s$

$s=\frac{12.8^2}{2\times 9.8}$

$s=8.35\ m$

In most compartment fires, the energy release in fire is directly proportional to the:

Liula [17]

In most compartment fires, the energy release in fire is directly proportional to the amount of oxygen available for combustion.

Answer: Option B

<u>Explanation:</u>

A fire is the chemical outcome of energy generated by the heat. So, this heat is generating fire due to friction between the heating source with igniting elements. And to increase the chain reaction of fire leading to combustion or fire require oxygen. So, the amount of oxygen will lead to the production of fire. Thus, the energy released by fire will be equal to the amount of oxygen available for combustion.

If there is no oxygen, then the fire will get succumbed. The fire consumes the oxygen present to increase the pace and spread of fire. So the consumed oxygen utilized for converting the simple fire to combustion will be equal to the release of energy in fire. Thus, energy released in fire is directly proportional to the amount of oxygen available for combustion.

Hallar la distancia que recorre una movil al cabo

Kryger [21]

Answer:

Distancia, S = 136 metros

Explanation:

Dados los siguientes datos;

Aceleración, a = 3 m/s²

Velocidad inicial, u = 5 m/s

Tiempo, t = 8 segundos

Para encontrar la distancia recorrida, usaríamos la segunda ecuación de movimiento;

S = ut + ½at² Sustituyendo en la fórmula, tenemos;

S = 5 × 8 + ½ × 3 × 8²

S = 40 + 1,5 × 64

S = 40 + 96

Distancia, S = 136 metros
