Answer:

D. place where a standing wave remains fixed in space.

Explanation:

A node is point where the amplitude of wave will be zero.But on the other hand a point where amplitude of wave is maximum is called anti node .When two wave superimpose then they form node and anti node continuously.

So we can say that ,a node is a place where a standing wave remains fixed in space.Stationary wave is called standing wave.

How might you measure the amount of energy in the world's largest rice cake?
enot [183]

Answer:

kindly check the explanation section.

Explanation:

The largest rice cake in the world was discovered in the year 2007 in South Korea with a weight of 8,113 lb. The amount of energy in the World's largest rice cake can be determined by using the formula below:

The energy in kJ =[ mass of water] x [specific heat capacity of water] x [change in temperature].

In order to determine experimentally in the laboratory and make use of the formula above. The first thing[STEP ONE] to do is to measure the mass of the rice cake and record it.

STEP TWO: measure a known amount of water in a boiling tube.  

STEP THREE: Heat the rice cake until it catches fire with a Bunsen flame.

STEP FOUR: Use the rice cake that has already caught fire in step three above and use it to heat the water in step two until the fire burns out.

Repeat the process for three to four times and record your observations under the following headings;

[1]. Mass of cake, [2]. Temperature  of water  before  burning, [3]. Temperature  of water after  burning and Temperature  increase per  gram of the rice cake.
