Answer:
1.72m
Explanation:
Step 1:
Data obtained from the question.
Displacement (x) = 0.15 m
Spring constant (K) = 300 N/m
Mass (m) = 0.2 kg
Height (h) =?
Step 2:
Determination of the energy in the spring.
The energy is a spring can be obtained by the following equation:
E = 1/2 kx^2
E = 1/2 x 300 x 0.15^2
E = 150 x 0.0225
E = 3.375J
Step 3:
Determination of the maximum height.
At maximum height, the energy stored is the spring is equal to the potential energy i.e
Energy stored in the string = potential energy
E = P.E
Recall:
Potential energy = mgh
Where:
m is the mass = 0.2kg
g is the acceleration due to gravity = 9.8m/s2
h is the height. =?
Potential energy (P.E) = 3.375J
PE = mgh
3.375 = 0.2 x 9.8 x h
Divide both side by 0.2 x 9.8
h = 3.375/ (0.2 x 9.8)
h = 1.72m
Therefore, the maximum height of the box is 1.72m
Answer:
1. Who gathered the data that showed planets traveling in elliptical paths around the sun?
2. Who discovered elliptical orbits?
3. Who explained them?
Explanation:
1. Tycho Brahe was the one that gathered data.
2. Johannes Kepler discovered it using Tycho Brace’s Data.
3. I believe it was Johannes Kepler because he created 3 laws of it.
I apologize if it is incorrect-
I hope it helps! Have a great day!

Answer: both hoops have the same kinetic energy at the bottom of the incline.
Explanation:
If we assume no work done by non conservative forces (like friction) , the total mechanical energy must be conserved.
K1 + U1 = K2 + U2
If both hoops start from rest, and we choose the bottom of the incline to be the the zero reference level for gravitational potential energy, then
K1 = 0 and U2 = 0
⇒ ΔK = ΔU = m g. h
If both inclines have the same height, and both hoops have the same mass m, the change in kinetic energy, must be the same for both hoops.
Answer:
Amino acids and proteins are the building blocks of life. When proteins are digested or broken down, amino acids are left. The human body uses amino acids to make proteins to help the body: Break down food.
