Other characteristic of radiation is the presence of positive and negative charge.
<h3 /><h3>What other characteristic does the radiation have?</h3>
Positive or negative charge are the other characteristic that is present in the radiation. Beta radiation have negative charge while on the other hand, alpha radiation have positive charge.
So we can conclude that other characteristic of radiation is the presence of positive and negative charge.

Answer:
The number of times voltage cycles in a minute in the U.S. is greater than the number of times voltage cycles in China.
Explanation:
An alternating current frequency is the rate at which current changes direction per second that is 1 hertz is equal to 1 cycle per second.
so therefore in US we will have 60 cycle per second which will be 3600 cycle per minute.
while in china will be 50 cycle per second which is equivalent to 3000 cycle per minute.
Note: the more current change direction per sec the voltage more cycle we have.
Converting minutes to seconds
1 minute = 60 seconds
5 minutes = 5 x 60 = 300 seconds.
distance
Time = - - - - - - - -
speed
Distance = time x speed = 300 x 3.5 = 1050 meters.
The car traveled 1050 meters.
Transparent and translucent materials transmit most of the light that strikes them, but not all of it. Light can also
reflect off these materials. When light reflects, it is bouncing off something. Windows transmit most of the light that strikes them, but they also reflect light. If you have a lamp turned on near a window at night, you can see the reflection of the lamp in the window.
Transparent and translucent materials also absorb some of the light that strikes them. When something absorbs light, it is soaking up the light. When light is absorbed by an object, the light energy changes to heat energy and the object heats up. If you touch a window that has been in the sunlight, you will notice that it is warm.
Opaque materials do not transmit any light. All of the light that strikes an opaque material is reflected or absorbe
