Answer:
0.75 g/cm^3
Explanation:
The formula for density:
Where m is the mass and V is the volume.
So, we can substitute values for m and V:
Therefore, the density is 0.75 g/cm^3 (watch the units!)
(1) Differentiate EN with respect to r, and then set the resulting expression equal to zero, since the curve of EN versus r is a
minimum at E0. (2) Solve for r in terms of A, B, and n, which yields r0, the equilibrium interionic spacing.
1 answer:
Answer: The continuation and the last part of the question is (3) Determine the expression for E0 by substitution of r0 into the above equation for EN. What is the equation that represents the expression for E0?
Explanation:
The detailed steps and appropriate derivation and by differentiation is shown in the attachment.
The knowledge of differential calculus is applied.

Answer:
the field at the center of solenoid 2 is 12 times the field at the center of solenoid 1.
Explanation:
Recall that the field inside a solenoid of length L, N turns, and a circulating current I, is given by the formula:
Then, if we assign the subindex "1" to the quantities that define the magnetic field () inside solenoid 1, we have:
notice that there is no dependence on the diameter of the solenoid for this formula.
Now, if we write a similar formula for solenoid 2, given that it has :
1) half the length of solenoid 1 . Then
2) twice as many turns as solenoid 1. Then
3) three times the current of solenoid 1. Then
we obtain:
Answer:
So the mass of the second object M will be 1.951 kg
Explanation:
We have given mass of the first object and its velocity
Mass of the second object it is at rest so its velocity
From conservation of momentum we know that
Initial momentum = final momentum
So
M = 1.951 kg
