Answer:

13.66 kJ

Explanation:

Given that

Mass of Pam, m = 40.4 kg

Distance moved by the force, d = 26.7 m

Speed attained by Pam, v = 26 m/s

The kinetic energy is given by the formula, K.E = 1/2 mv², where

K.E = the needed kinetic energy

m = mass of the object(Pam)

v = velocity of the object(Pam)

Applying the formula, we have

K.E = 1/2 * 40.4 * 26²

K.E = 20.2 * 676

K.E = 13655.2 J

The Kinetic Energy is 13.66 kJ

A. Obtain the following: microwave, ruler, something meltable (e.g. candy bar, marshmallows) B. A microwave works by setting up
Makovka662 [10]

Answer:

E = 124.7 N / C

Explanation:

Let's analyze the exercise: the microwave creates an electromagnetic wave of frequency F = 2.45 GHz, this wave is introduced into the microwave cavity and is reflected on the metal walls, which is why one or more standing waves are formed.

The electric field of the standing wave is

            I = E²

            E =√I

where I is the intensity of the radiation.

What is it

             I = P / A

where P is the effective emission power, almost all the power of the microwave and A is the area of ​​the cavity, in the most used microwaves

P = 700 W and the area is A = 25 x 18 cm² = 0.045 m²

             I = 700 / 0.045

             I = 15555.56 W/m²

let's calculate the electric field

            E = √15555.56

            E = 124.7 N / C

Answer the question with step.​
Maru [420]

Answer:

f1/f2 =W1/W2 = 1/3

.0 f2 = 3f1

As ,

1/F= 1/f1 +1/f2

...1/40 = 1/f1 - 1/3f1

f1=> 80/3 cm

... f2 = 2f1 = 3 x 80/3 = 80 cm
