we measure a voltage difference of 5.0 V between two points on the conducting paper between two parallel conducting electrodes.

Alex17521 [72]

Answer:

E=1824.81 V/m

Explanation:

Given that

Voltage difference = 5 V

Distance ,D= 3 mm

θ = 24°

As we know that electric filed given as

$E=\dfrac{V}{d}$

Given that D is 24° with respect to the perpendicular to the electrodes.So we have to take cos component of D.

d= D cosθ

d= 3 cos24°

d = 2.74 mm

$E=\dfrac{V}{d}$

$E=\dfrac{5}{2.74\times 10^{-3}}$

E=1824.81 V/m

Microwave ovens have a plate that rotates at a rate of about 7.0 rev/min. What is this in revolutions per second?

Lera25 [3.4K]

Answer:

The value is $w = 0.1167 \ rev/second$

Explanation:

From the question we are told that

The rate at which the plate rotates is $w =7.0 \ rev/min$

Generally the revolution per second is mathematically represented as

$w = \frac{7.0}{60}$

=> $w = 0.1167 \ rev/second$
