Well! see the car experiences 300 N force to the right from the engine.

It also experiences 150N force to left due to friction and air resistance

Now, we know it is the net force which will decide the car will move in which direction

We have net force=300-150=150N

which is towards right

So that means car will accelerate in right direction.

Hope it helps!!

Once a ball leaves a table at 10 m/s, how long will it take to hit the floor
Zarrin [17]

<u>Answer:</u>

The time taken for the ball to hit the floor as 1.02 seconds

<u>Explanation:</u>

As per the given question, the ball leaves at a speed from the table with an initial velocity of 10 m/s, we have the equation

\mathrm{V}_{\mathrm{f}}=\mathrm{V}_{\mathrm{i}}+\mathrm{at}

where Vf represents the final velocity

 Vi represents the initial velocity  

a represents the acceleration and

t represents the time

\mathrm{V}_{\mathrm{f}}=\mathrm{V}_{\mathrm{i}}+\mathrm{at} after rearranging

 \mathrm{t}=\frac{\mathrm{vf}-\mathrm{vi}}{a}

  \mathrm{t}=\frac{0-10}{9.8}  = 1.022 seconds

1. Determina el momento que produce una fuerza de 7 N tangente a una rueda de un metro de diámetro, sabiendo que el punto de apl
Rudik [331]

Answer:

τ= F r     into the blade

Explanation:

The moment of a force is defined by

         τ = F x r

where the bold indicates vectors

Let us write in the expression in magnitude

         τ = F r sin θ

in our case the force is tangent to the wheel therefore the angle between F and the radius is 90º, and the sin 90 = 1

       τ= F r

The direction of τ can be used by the rule of the right hand, the fingers curve in the direction of the torque when advancing from the force to the radius and the thumb points in the direction of the torque.

In this case, for a clockwise rotation, the fingers are curved in the direction and the thumb points into the blade, this is the direction of the τ.

TRASLATE

El momento de una fura es definido por

         τ = F x r

donde la negrillas indican vectores

Escribamos en ta expresión en magnitud

          τ = F r sin θ

en nuestro caso la fuerza es tangente a la rueda por lo tanto el angulo entre F y el radios es 90º, y el sin 90=1

        τ = F r

la dirección de tau la podemos  usar la regla de la mano derecha, los dedos curva en la dirección del torque al avanzar dese la fuerza al radio y el pulgar apunta en la dirección del torque.

En este caso para un giro en sentido horario los dedos se curvan ente sentido y el pulgar apunta hacia dentro de lla hoja, esta es la dirección del troque

The characteristic that gives an element its distinctive properties is its number of:_________
oee [108]

The characteristic that gives an element its distinctive properties is its number of protons because the number of protons of any element represents its atomic number.

<h3>What is the atomic number?</h3>

The total number of protons present in an atom is known as the atomic number of that atom. The atomic number has no correlation either with the number of neutrons or the number of electrons present inside an atom.

Since the number of protons in any element corresponds to its atomic number, this property provides an element with its particular features.
