Answer:

Meter

Explanation:

International System of Quantities is given for the seven base quantities. Meter is one of them. The meter, symbol m, is the SI unit of length. It is defined as the distance covered by the speed of light in vacuum to be 299792458.

The SI base unit that is used for measuring length is meters. Some other units are kilometers, millimeters. etc.

La magnitud del campo eléctrico E entre dos placas paralelas es 8kN/C. Las placas están separadas 0.03m. ?Cuánto trabajo realiza
olchik [2.2K]
<h2>Respuesta:</h2>

Si tenemos dos placas paralelas y un campo electrico de 8kN/C entre ellas y además conocemos la separación de estas placas que es igual a 0.03m. Entonces, cuando una carga se mueve de un punto a a un punto b el trabajo que es realizado  sobre la carga por el campo eléctrico viene dado por la siguiente ecuación:

W_{a \rightarrow b}=q_{0}E(y_{a}-y_{b})

Dado que la carga se mueve desde la placa negativa hasta la placa positiva, entonces:

y_{a}

W_{a \rightarrow b}=q_{0}E(-d) \\ \\ W_{a \rightarrow b}=-q_{0}Ed

Finalmente, sustituyendo:

W_{a \rightarrow b}=-(-3 \times 10^{-6})(8\times 10^{3})(0.03) \\ \\ \boxed{W_{a \rightarrow b}=7.2\times 10^{-4}J}

Which of the following has more inertia?? bowling ball , hammer, Tennis ball feather
I am Lyosha [343]
The bowling ball would have the most inertia because it has the most mass. Inertia is the ability to resist a change in motion. So, it sort of makes sense that the more massive an object, the more resistance it has against outside forces. 
Bowling ball would be your answer since it has the most mass.

2. This diagram represents a top-down view of an experiment on a table. The 250 g and 100 g masses are falling and are pulling t
Rasek [7]

Answer:

According to the data given in the question, experiment on table two pulling and falling masses are arranged in the fig. 250  g is pulling right side and   100 g pulling down. The gravitational force is common to both the masses, so we cannot say that the block moves towards heavier mass, also the block  does not move towards the lighter mass.

Obviously, the effect of heavier mass of 250 g is more on the block, so the block moves towards right bottom corner. i.e., diagonally between two masses

How do you find the acceleration of an object?
artcher [175]
Rearrange the equation F = ma to solve for acceleration<span>. You can change this formula around to solve for </span>acceleration<span> by dividing both sides by the mass, so: a = F/m. To find the </span>acceleration<span>, simply divide the force by the mass of the </span>object <span>being accelerated.

Hope i helped :)</span>
