So you would take the 360 cm and divide it by 2.5 cm or 1 inch to see how many inches the ceiling is.
360÷2.5= 144 inches
Answer:
x=1, y=-1
Step-by-step explanation:
Given the equation:
where x and y are the blank boxes.
We want to find
A positive value of x
A negative value of y
That makes the equation true.
If x=1, y=-1
This can be confirmed using addition law of indices()
In general, any pair of a number and its negative value will satisfy the equality.
Step-by-step explanation:
Answer:
(a) 62.5 N
(b) 694.4 N/m
(c) 41.7 N
Step-by-step explanation:
Work done in stretching a spring is
since 
F is the applied force, E is the elongation and k is the spring constant.
(a) Here, e = 16 cm = 0.16 m
(b) Here, e = 12 cm = 0.12 m
(c) The restoring force is the same as the applied force.
One way is you can divide 30 by a certain amount
The answer to this problem is x=210
