Answer:
0.1m/s
Explanation:
The speed, which refers to how fast an object moves within a period of time, can be calculated as follows:
Speed (m/s) = distance (m)/time (s)
Based on the provided information in the question, distance = 10m, time = 100s
Hence, the speed will be:
Speed = 10/100
Speed = 0.1m/s
<u>Answer:</u>
The correct answer option is D. Carry nerve impulses from the brain to skin, glands, and muscles
<u>Explanation:</u>
Motor neurons carry signals out of the Central Nervous System (CNS).
These motor neurons have long extensions called axons which spread from the CNS to the muscles that connect with the innervate.
The information from the brain to the muscles and other glands is sent in the form of electrical impulses via the spinal cord.
Answer:
Option (1), (2), (3), and (5)
Explanation:
Maps are the 2-dimensional representation of the earth on a sheet of paper. These maps are of various types such as the geographical map, topographic map, as well as weather maps.
The weather/topographic maps are mostly used by the geologists, meteorologists, and geographers.
These maps provide various details regarding a particular area, such as-
<u>(a) Isobars-</u> These are the lines present on the map with an equal amount of pressure.
<u>(b) Isolines-</u> These are lines of equal elevation. They are also known as contour lines.
<u>(c) Precipitation type-</u> In the common weather maps, the precipitation type also is discovered, which occurs in the form of rain, snow, drizzle and hail.
Thus, the correct answers are options (1), (2), (3), and (5).
