Answer:
10.01 cm
Explanation:
Given that,
The time delay between transmission and the arrival of the reflected wave of a signal using ultrasound traveling through a piece of fat tissue was 0.13 ms.
The average propagation speed for sound in body tissue is 1540 m/s.
We need to find the depth when the reflection occur. We know that, the distance is double when transmitting and arriving. So,

or
d = 10.01 cm
So, the reflection will occur at 10.01 cm.
in english please
i don't understand actually
Electrical resistance is an objects ability to resist or oppose current which means its resistance is defined as ohms since that is the person who discovered it. And an experiment to study this would be a multimeter in a circuit testing current and change the material of the wire allowing you to see the change in current due to change in resistance
In order to find number of neutrons, use this formula: Mass number-number of protons. The number of protons is equal to the atomic number.
Using this, you do 96-34 to get 62 neutrons. Hope this is helpful!
Answer:
It is because convection take place. Convection is a transfer of heat by the movement of gases or liquid where warm air is less dense than cold air so <u>h</u><u>o</u><u>t</u><u> </u><u>a</u><u>i</u><u>r</u><u> </u><u>r</u><u>i</u><u>s</u><u>e</u><u>s</u><u> </u><u>a</u><u>n</u><u>d</u><u> </u><u>c</u><u>o</u><u>l</u><u>d</u><u> </u><u>a</u><u>i</u><u>r</u><u> </u><u>s</u><u>i</u><u>n</u><u>k</u><u>s</u>.
