Answer:

60Watts

Explanation:

Given parameters:

Current = 0.5A

Voltage  = 120V

Unknown

Power = ?

Solution:

The power in the electric circuit is the product of current and voltage;

      P = IV

Insert the given parameters and solve;

      P = 0.5 x 120

      P  = 60Watts

Tres autos parten de un mismo punto con un intervalo de 1s, con velocidades "3V", "5V" y "Vx", respectivamente hacia un punto "p
kkurt [141]

Answer:

Vx = 15V

Explanation:

To find the speed of the third car you take into account that the distance that they travel is the same. Only time is different in one second. Mathematically you have:

x=3vt\ \ \ \ \ (1)\\\\x=5v(t-1)\ \ \ \ (2)\\\\x=v_x(t-2)\ \ \ \ (3)

you equal the first and second equation obtain the time t:

3vt=5v(t-1)\\\\3t=5(t-1)\\\\3t=5t-5\\\\t=\frac{5}{2}s=2.5s

then, you can equal the third and first equation:

3vt=v_x(t-2)\\\\3(2.5s)v=(2.5s-2s)v_x\\\\7.5v=0.5v_x\\\\v_x=15v

hence, Vx = 15V

TRANSLATION:

Para encontrar la velocidad del tercer automóvil, tenga en cuenta que la distancia que recorren es la misma. Solo el tiempo es diferente en un segundo. Matemáticamente tienes:

iguala la primera y segunda ecuación obtiene el tiempo t:

entonces, puedes igualar la tercera y primera ecuación:

por lo tanto, Vx = 15V

Witch is true according to the law of conservation of energy?
Elanso [62]

Explanation:

The law of conservation of energy is one of the fundamental laws of science that helps to understand energy in nature.

Energy is the ability to do work. There are different forms of energy.

Generally, energy is classified into potential and kinetic forms of energy. Potential energy is the energy at rest in a body. It is due to the position of the body.

Kinetic energy is the energy due to the motion of a body.

There are different forms of kinetic and potential energy and they are related by the law of conservation of energy.

The law states that "in an isolated system, energy is neither created nor destroyed by transformed from one form to another".

An isolated system is a system in which there is no exchange of matter and energy.

Due to this we know that no new energy is created or destroyed, they are only transformed from one form to the other.

Does the efficiency of a motor depend on mass?
Valentin [98]

Practically yes

  • Efficiency=Output/input

So

If mass is more output may come less so it affects the efficiency practically

But thepritically it doesn't
