Answer:
5083
Step-by-step explanation:
6^3 + 5(8 + 15)
Simplify the bracket first
6 x 6 x 6 + 5 (23)
216 + 5 (23)
221 (23)
221 x 23 = 5083
Answer:
Area of pathway = 10.375 unit²
Step-by-step explanation:
Given - Peter has built a gazebo, whose shape is a regular heptagon, with
a side length of 1 unit. He has also built a pathway around the
gazebo, of constant width 1 unit, as shown below.
To find - Find the area of the pathway.
Proof -
Central angle =
= 51.43°
Now,
Central angle / 2 =
= 25.71°
And
height =
= 1.038
Now,
Inner area of gazebo = 7·
·1·(1.038) = 3.634 unit²
Outer area of gazebo = (
)²·(3.364) = 14.009 unit²
∴ we get
Area of pathway = Outer area - Inner area
= 14.009 - 3.634
= 10.375 unit²
⇒Area of pathway = 10.375 unit²
Answer:
Two negative charges will not attract each other.
Step-by-step explanation:
According to the law of electrostatic induction, it states that "Like charges repel, unlike charges attracts.
Charges can either be positive or negative. For the charges to repel, charges with the same sign must be brought together e.g positive-positve or negative-negative.
For the charges to attract, charges with different sign must be brought together e.g positive-negative or negative-positive.
Based on the conclusion above, it can be seen that the table is incorrect because two negatively charged particle will always repel not attract.
