Answer:
Spring constant, k = 200 N/m
Explanation:
Given the following data;
Potential energy = 0.36 J
Extension, e = 6 cm
Conversion:
100 cm = 1 meters
6 cm = 6/100 = 0.06 meters
To find the spring constant;
Mathematically, the energy stored in a spring is given by the formula;
Where;
E is the energy.
K is the spring constant.
x is the extension of the spring.
Substituting into the formula, we have;
Cross-multiplying, we have;
Spring constant, k = 200 N/m
That's false. "Weight" is the measure of the gravitational
attraction between two objects. It depends on the masses
of both of them.
Answer:
Stalactites
Explanation:
these formations are created by dripping water in a cave that is rich in minerals that develop for hundreds of years. stalagmites are also known for their comedic name "cave bacon" I hope this helped!
The first one is: head
Second one is: 10 trillion km
Answer:
The object distance is 92 cm.
Explanation:
let v be the image distance and h be the height of the image, let u the be the object distance and H be the height of the object.
then, the magification of the mirror is given by:
m = -v/u and m = h/H
so, -v/u = h/H
u = -v×H/h
= -(-4.6)×(82)/(4.1)
= 92 cm
Therefore, the object distance is 92 cm.
