which of the following means "free from all organisms''?
1.clean
2.disinfected
3.contaminated
4.sterilization

Answer:

First Law of Motion.

Explanation:

Inertia can be defined as the tendency of an object or a body to continue in its state of motion or remain at rest unless acted upon by an external force.

In physics, Sir Isaac Newton's First Law of Motion is known as Law of Inertia and it states that, an object or a physical body in motion will continue in its state of motion at continuous velocity (the same speed and direction) or, if at rest, will remain at rest unless acted upon by an external force.

The inertia of a physical object such as a truck is greatly dependent or influenced by its mass; the higher the quantity of matter in a truck, the greater will be its tendency to continuously remain at rest.

Hence, it would take much more force and time for a large truck to get going when the traffic light turns green than it does for a small, compact car. This is an example of the first law of motion.

Answer:

Resistance = 252.53 Ohms

Explanation:

Given the following data;

Charge = 0.125 C

Voltage = 5 V

Time = 6.3 seconds

To find the resistance;

First of all, we would determine the current flowing through the battery;

Quantity of charge, Q = current * time

0.125 = current * 6.3

Current = 0.125/6.3

Current = 0.0198 A

Next, we find the resistance;

Resistance = voltage/current

Resistance = 5/0.0198

Resistance = 252.53 Ohms

The answer to the question is logic

Answer:

approximately 35,786 km

Explanation:

A satellite in such an orbit is at an altitude of approximately 35,786 km (22,236 mi) above mean sea level. It maintains the same position relative to the Earth's surface.

Answer:

(iii) 300m

Explanation:

(i) The velocity of the cyclist is constant with time, the rate of the change of the velocity with the time is zero. So the acceleration of the object will be zero.

(ii) According to the graph we observe that the cyclist is moving with the same velocity all the time, therefore, the velocity of the cyclist is [tex]20m/s^{-1}[/tex]

(iii) Apply the formula: (speed = velocity x time)

s = vt

s = [tex]20m/s^{-1}[/tex] x 15s

s = 300m

Hope this helps :)

Answer:

The correct option is (c).

Explanation:

The electrostatic force between charges is given by :

[tex]F=k\dfrac{q_1q_2}{r^2}[/tex]

Where

r is the distance between charges

If the distance between two electric charges is tripled, r' =3r

New force becomes,

[tex]F'=k\dfrac{q_1q_2}{(3r)^2}\\\\F'=k\dfrac{q_1q_2}{9r^2}\\\\F'=\dfrac{1}{9}\times k\dfrac{q_1q_2}{r^2}\\\\F'=\dfrac{F}{9}[/tex]

So, the new force becomes 1/9 of the original force. The correct option is (c).

Answer:

[tex] y_{t} = 253.94 m [/tex]

Explanation:

Para resolver este problema debemos contemplar dos tramos.

En el primer tramo, la fuerza aplicada impulsa al cuerpo a subir una altura dada debido a la aceleración que genera esa fuerza.

[tex] \Sigma F = ma [/tex]

[tex] F - P = ma [/tex]

[tex] F - mg = ma [/tex]

En donde:

F: es la fuerza aplicada = 60 N

P: es el peso del cuerpo = mg

m: es la masa del cuerpo = 4 kg

g: es la aceleración debido a la gravedad = 9.81 m/s²

a: es la aceleración

Entonces, la aceleración generada por la fuerza aplicada es:

[tex] a = \frac{F - mg}{m} = \frac{60 N - 4kg*9.81 m/s^{2}}{4 kg} = 5.19 m/s^{2} [/tex]

Ahora, debemos calcular la altura recorrida mientras el cuerpo está acelerado hacia arriba:

[tex] y_{{1}} = y_{0} + v_{0}t + \frac{1}{2}at^{2} [/tex]  

En donde:

[tex] y_{1}[/tex]: es la altura final del tramo 1 =?                                                                          [tex] y_{0}[/tex]: es la altura inicial = 0  

[tex] v_{0}[/tex]: es la velocidad inicial = 0 (parte del reposo)  

t: es el tiempo = 8 s

[tex] y_{1} = 0 + 0 + \frac{1}{2}5.19 m/s^{2}*(8 s)^{2} = 166.08 m [/tex]  

Por lo tanto, mientras el cuerpo está acelerado (durante los 8 s) recorre 166.08 metros.  

Ahora, en el segundo tramo el cuerpo sigue subiendo hasta alcanzar una altura máxima para luego comenzar a descender. Podemos usar la siguiente ecuación para calcular la altura recorrida.  

[tex] v_{f}^{2} = v_{0}^{2} - 2gy_{2} [/tex]  

En donde:    

[tex] v_{f}[/tex]: es la velocidad final = 0 (en la altura máxima)

[tex] v_{0}[/tex]: es la velocidad inicial

Primero debemos encontrar la velocidad inicial en el segundo tramo, que es igual a la velocidad final del primer tramo:

[tex] v_{f} = \sqrt{v_{0} + 2ay_{1}} = \sqrt{0 + 2*5.19 m/s^{2}*166.08 m} = 41.52 m/s [/tex]    

Entonces, la altura recorrida en el segundo tramo es:

[tex] y_{2} = \frac{v_{0}^{2} - v_{f}^{2}}{2g} = \frac{(41.52 m/s)^{2} - 0}{2*9.81 m/s^{2}} = 87.86 m [/tex]

Finalmente, la altura máxima es:

[tex]y_{t} = y_{1} + y_{2} = 166.08 m + 87.86 m = 253.94 m[/tex]

Tension = Mass * Gravity

Tension = 15 * 9.81 = 147.15

Answer:

The information shows the masses after the compounds are balanced.

2MgO + 2Cl2 → 2MgCl2 + O2

85g + 156g → 188g + 53g

53gas total mass in reactant is equal to product.

A.

53g of O2, because all mass must be conserved.

Answer:This could be in the form of using fewer energy services or using devices that require less energy.

Explanation:

Answer:

The second law of thermodynamics states in an isolated system, the entropy (the amount of thermal energy that cannot be converted into mechanical work, also known as the amount of disorder) always increases, therefore, an isolated system always require an external input (new sources) of energy for there to be orderliness or for the available energy of the system to remain constant or increase

Explanation:

Answer: I believe the correct answer would be they join north pole to south pole. The direction of these lines always goes from the direction of north to south pole. These lines forms loops in order to favor the way which requires or has less resistance. Hope this helps.

Answer:

162 KJ

Explanation:

The electrical energy can be calculated using the formula

E = V×I×t

Where, V= voltage = 120 V

I is current in ampere = 7.5 A and t is time in seconds

1 hour = 3600 sec

Therefore, 0.05 hour = 3600×0.05 = 180 sec

Substitute the values in above equation find electrical power

E = 120×7.5×180

= 162000 J

= 162 KJ

Therefore, the electrical energy use of the microwave = 162 KJ

d = 10 m

Explanation:

Work = force × distance

or

distance = work/force

= (240 J)/(24 N)

= 10 m

Answer:

This relationship is from Newtons Second Law of Motion

Newton's second law shows that there is a direct relationship between force and acceleration. The greater the force that is applied to an object of a given mass, the more the object will accelerate.

Its expressed as

F=ma

Answer:

Explained below.

Explanation:

Newton's first law of motion states that an object will continue in its present state of rest or continue with constant speed in a straight line except it is acted upon by an external force.

For every object in motion or at rest there is a force of friction that tries to resist its motion or prevent it from moving with constant velocity.

Now, to push it from rest you will need to apply a force large enough to overcome its static friction. Now, after that initial motion, smaller forces will have to be applied to overcome what is called sliding friction that prevents the crate from sliding which will affect the constant velocity.
