1. What are advantages and disadvantages of using a solar cooker compared to other meanings of cookings?
Brums [2.3K]

Answer:

The biggest advantage of Solar cookers is their eco-friendliness. By exploitation one you’ll decrease your dependence on gas or electricity, cut back your carbon footprint, and save on fuel and therefore the value of fuel on running home appliances. change of state with star cookers clearly needs daylight, that makes it troublesome to use throughout winter months and on rainy days. change of state conjointly takes a considerably longer time compared to traditional strategies. Users should schedule their change of state time and maximize the employment of daylight. As a result, preparation should begin early within the morning in order that the food may be placed in the cooking utensil by noontide.

Explanation:

Hope this helps

The turntable in a microwave oven has a moment of inertia of 0.039 kg⋅m2 and is rotating once every 4.4 s . Part A What is its k
gayaneshka [121]

To solve this problem it is necessary to apply the concepts related to Kinetic Energy, specifically, since it is a body with angular movement, the kinetic rotational energy. Recall that kinetic energy is defined as the work necessary to accelerate a body of a given mass from rest to the indicated speed.

Mathematically it can be expressed as,

KE = \frac{1}{2} I\omega^2

Where

I = Moment of Inertia

\omega =Angular velocity

Our values are given as

I = 0.039kg\cdot m^2

A revolution is made every 4.4 seconds.

\theta = 1 rev \rightarrow 4.4s

\Rightarrow \omega = \frac{1rev}{4.4s}

If the angular velocity is equivalent to the displacement over the time it takes to perform it then

\omega = 0.2272rev/s(\frac{2\pi rad}{1rev})

\omega = 1.42rad/s

Replacing at our previous equation we have,

KE = \frac{1}{2} I\omega^2

KE = \frac{1}{2} (0.039)(1.42)^2

KE = 0.03993J

Therefore the kinetic energy is equal to 3.9*10^{-2}J
