Answer:
Ep = 3704.4 J
Explanation:
Data:
- Mass (m) = 126 kg
- Gravity (g) = 9.8 m/s²
- Height (h) = 3 m
- Potential Energy (Ep) = ?
Use formula:
Replace:
- Ep = 126 kg * 9.8 m/s² * 3 m
Multiply, but it tells us that the units should not be used in the answer, so we solve it as follows:
What is the GPE?
The GPE is <u>3704.4 Joules.</u>
Answer:
The equation which define the work done by spring is w = 45 x³ - 8 x²
Explanation:
Given as :
The force is the function of distance x
I.e F(x) = a x² - b x
where
a = 45 N/m²
b = 8 N/m
Now, Wok done = Force ×displacement
I.e W = F . ds
So , W = (a x² - b x) × x
or, W = (45 x² - 8 x) × x
Or, w = 45 x³ - 8 x²
So, the equation which define the work done by spring is w = 45 x³ - 8 x²
Hence The equation which define the work done by spring is w = 45 x³ - 8 x² Answer
Answer:
Migration
Explanation:
Migration is the movement of organisms from one region or place of habitat to another region. Organisms migrate from one region to another to increase their rates of survival. Migration of organisms from one habitat to another may be due to unavailability of insufficiency of resources that are required for their survival.
Sorry if you get this wrong but I believe it’s C because without inertia.. particles will fall apart because inertia keeps everything together in the same motion
Answer:
Explanation:A covalent bond is formed when electrons are shared between non-metal atoms, and the positive nuclei are attracted towards the pair of negative bonded electrons. ... Hence, the hydrogen bond is weaker than ionic and covalent bonds. Example: Water molecules are held to each other by intermolecular forces of attraction.
