Answer:

Technician A only

Explanation:

Here we have electromagnetic energy is an energy form that is emitted from charged objects as electrical and magnetic waves with a capability to move through space as electromagnetic radiation.

Examples of electromagnetic energy and electromagnetic radiation includes, visible light, radio waves, X-rays, gamma rays and Sunlight

While electrochemical energy is the energy through which chemical energy is converted into electrical energy and electrical energy is converted into chemical energy. Electrochemical energy has to do with batteries, super and ultra capacitors and electrochemical cell.

Since the filaments electrical setup does not comprise of an electrochemical cell and light is not a form of chemical energy, therefore, technician A only is correct.

eduard

Answer:

D quadruple

Explanation:

E = \frac{1}{2}mv^2\\E'=\frac{1}{2}m(2v)^2=\frac{1}{2}m4 v^2 = 4(\frac{1}{2}mv^2)=4E

A 100 kg person sits on a 5 kg bicycle. The total weight is borne equally by the two wheels of the bicycle. The tires are 2.0 cm
timofeeve [1]

To solve this exercise it is necessary to take into account the concepts related to Pressure depending on the Force and the Area.

The pressure is defined as

P =\frac{F}{A}

Where,

F_w = Force

A = Area

Our values are given as,

m_1 = 100Kg

m_2 = 5Kg

Where m_1 is the mass of the person and m_2 is mass of cycle. Therefore the total mass at the system is 105Kg.

For Newton's second law we have:

F = ma \rightarrow where a is the acceleration, in this case the same Gravitational acceleration.

We need to make two considerations, the first is to calculate the total weight and second to calculate the weight on each wheel (2), that is

F_T = 105*9.8

F_T = 1030.05N

Force in each wheel,

F_{wheel} = \frac{1030.05}{2}

F_{wheel} = 515.025N

In this way we can now calculate the length based on the pressure, that is

P = \frac{F_T}{A}

P = \frac{F_T}{L*W}

L = \frac{F_T}{P*W}

L = \frac{515.025}{(8*10^{5})(2*10^{-2})}

L = 0.0321m

Therefore each tire has 3.21cm
