Boron Group
elements have three valence electrons and are fairly reactive. All of them are solids at room temperature. Boron is a very hard, black metalloid with a high melting point.
If object is not accelerating, the sum of all forces on the object will be equal to ZERO...
Answer:
Explanation:
(a) It is given that Joseph jogs on a straight road of 300m in a time interval of 2 minutes and 30 seconds, which is equal to 150seconds. Therefore, when Joseph jogs from point A to point B, he covers a distance of 300m in time of 150seconds. Hence, his average speed is 300m/150s=2ms^−1. Since it is a straight road and he jogs in a single direction in this case, his displacement is equal to 300m. Since it is a straight road and he jogs in a single direction in this case, his displacement is equal to 300m.
Hence, his average velocity is 300m/150s=2ms^−1
(b) Then it is given that he turns back and points B and jogs on the same road but in the opposite direction for a time interval for 1 minute and covers a distance of 100m.If we consider the whole motion of Joseph, i.e. from point A to point C, then he covers a total distance of 300m+100m=400m. And he covers this total distance in a time interval of 2.5min+1min=3.5min=210s.
Therefore, his average speed for this journey is 400m210s=1.9ms−1.
For the same journey is displacement is equal to the distance between the points A and C,i.e. 300m−100m=200m.
Hence, his average velocity for this case is 200m/210s=0.95ms^−1
Answer:
The answer is: "Social Media tools"
Explanation:
"Social Media tools" are <u>very popular tools being used by the modern generation these days.</u> They come in different types according to their usage (Listening Platforms, Publishing Platforms and Competitive Analysis Platforms). Examples of these are: <em>Hootsuite, Buffer, Oktopost, Canva, Google Trends, BuzzSumo, etc.</em>
These tools allow people to interact with one another. People can published the information they want to share and distribute this information to other people. Marketers also use these tools in order to aid them regarding online businesses and the like. Some social media tools are available for free while others have to be purchased.
Thus, this explains the answer.
