Answer:
0.8J
Explanation:
Given parameters:
Force = 20N
Compression = 0.08m
Unknown:
Spring constant = ?
Elastic potential energy = ?
Solution:
To solve this problem, we use the expression below:
F = k e
F is the force
k is the spring constant
e is the compression
20 = k x 0.08
k = 250N/m
Elastic potential energy;
EPE =
k e² =
x 250 x 0.08²
Elastic potential energy = 0.8J
Polar molecules do have ionic bonds
Answer:
I have a screenshot of this.
Explanation:
Answer:
Copper
Explanation:
Since the heat of Fussion of copper is less than that for nickel it means copper melts faster than nickel.
