Nearest hundred is 300 anything 50 and above rounds up and below 50 it rounds down
Answer:
W₂ is three times W₁ (W₂ = 3W₁)
Step-by-step explanation:
Applying,
W = ke²/2............. Equation 1
Where W = workdone in stretching the spring, k = spring constant, e = extension.
For W₁,
W₁ = ke₁²/2
Given: e₁ = 30-20 = 10 cm = 0.1 m
Substitute these value into equation 1
W₁ = k(0.1²)/2
W₁ = 0.005k Joules
For W₂,
W₂ = (ke/2)-W₁
Given: e = (40-20) = 20 cm = 0.1 m
Substitute these value into equation 1
W₂ = (k×0.2²/2)-0.005
W₂ = 0.015k Joules.
W₂/W₁ = 0.015k/0.005k
W₂/W₁ = 3
Therefore,
W₂ = 3W₁
I think it should be 7g?
Not sure tho
Answer:
x=-2/3
Step-by-step explanation:
1st you have to get rid of the number next to the x value
so you divide
Answer:
A, B
Step-by-step explanation:
1. A
because the intersection of the line is the solution so no solution means they do not intersect
2. B
because the points on the line that is on top of another line are all solutions and lines have infinite number of points
