The answer is D.  The temperature obviously doesnt rise slower or faster, and if you are heating an object, it would make no sense to say that less heat is being transferred.

Explain, briefly, what the electrical field inside a microwave oven does to heat food.
yarga [219]

Answer:

Inside the strong metal box, there is a microwave generator called a magnetron. When you start cooking, the magnetron takes electricity from the power outlet and converts it into high-powered, 12cm (4.7 inch) radio waves. Thus the microwaves pass their energy onto the molecules in the food, rapidly heating it up.May 3, 2018

An open train car moves with speed 18.5 m/s on a flat frictionless railroad track, with no engine pulling the car. It begins to
olga2289 [7]

Answer:

The speed decreases.

Explanation:

This can be explained using the conservation of linear momentum.

Since there is no friction, the initial moment of the train must be equal to its linear moment after it is filled with water.

the initial linear momentum is

m_{1}v_{1}

where m_{1} is the initial mass of the train, and v_{1} the initial speed of the train.

And linear momentum after the water filled the train car is

m_{2}v_{2}

where m_{2} is mass of the train after the  rain, and v_{2} the speed of the train after the rain

<u>the equality must be fulfilled:</u>

m_{1}v_{1}=m_{2}v_{2}

We know that if water is added to the train, m_{2} that is the mass after the water is added, is greater than m_{1} which is the mass of the train without the water.

Therefore, in order for the conservation of the linear momentum to be fulfilled: m_{1}v_{1}=m_{2}v_{2}

the speed after the water is added (v_{2} ) must be smaller than the initial train speed (v_{1} ) . So the speed of the car decreases.

PLEASE HEELP!!!
Ann [662]

Answer:

The "pressure" of the electricity is electric potential. Electric potential is the amount of energy available to push each unit of charge through an electric circuit. The unit of electric potential is the volt. ... A volt is the force needed to move one amp through a conductor that has 1 ohm of resistance

Could someone please explain to me Archimede's principle without using the term displace (or at least explaining what it means)?
disa [49]
Does this help?

When an object is immersed in a fluid (in this case water, but may include both liquids and gases) the fluid exerts an upward force on the object which is called buoyancy force or <span>up-thrust.  Archimedes’ Principle states that the buoyant force (upward push or force) applied to an object is equal to the weight of the fluid that the object takes the space of by that object.  Thus when an object is placed in water the rise in the water level is dictated by the mass of that object.</span>

<span>
</span>

<span>So for example if you fill a bucket with water and you drop a stone in that bucket, if you measure the weight of the water that overflows from the bucket due to the stone being dropped into the bucket is equivalent to the pushing force that the water has on the stone (as the stone drops to the bottom of the bucket the water is pushing it to stay afloat but the rock is more dense than water and as such its downthrust exceeds water's upthrust).</span>
