To determine the volume of the aluminum given that it has the same mass as the iron given, we need to divide the mass with the density of aluminum. We calculate as follows:
Volume of aluminum = 70.83 / 2.70 = 26.23 cc
Hope this answers the question. Have a nice day.
Answer:
0.5m/s^2
Explanation:
net force (resultant force) = mass x acceleration
100N/200kg = 0.5
Answer:
a)
b)
c)
d) or 18.3 cm
Explanation:
For this case we have the following system with the forces on the figure attached.
We know that the spring compresses a total distance of x=0.10 m
Part a
The gravitational force is defined as mg so on this case the work donde by the gravity is:
Part b
For this case first we can convert the spring constant to N/m like this:
And the work donde by the spring on this case is given by:
Part c
We can assume that the initial velocity for the block is Vi and is at rest from the end of the movement. If we use balance of energy we got:
And if we solve for the initial velocity we got:
Part d
Let d1 represent the new maximum distance, in order to find it we know that :
And replacing we got:
And we can put the terms like this:
If we multiply all the equation by 2 we got:
Now we can replace the values and we got:
And solving the quadratic equation we got that the solution for or 18.3 cm because the negative solution not make sense.
Answer:
(a). The thickness of the glass is 868 nm.
(b). The wavelength is 3472 nm.
Explanation:
Given that,
Refractive index = 1.20
Wavelength = 496 nm
Next wavelength = 386 nm
We need to calculate the thickness of the glass
Using formula for constructive interference
Put the value into the formula
In first case,
.....(I)
In second case,
.....(II)
From equation (I) and (II)
Put the value of m in equation (I)
The thickness of the glass is 868 nm.
(b). We need to calculate the wavelength
Using formula of constructive interference
Put the value into the formula
Hence, (a). The thickness of the glass is 868 nm.
(b). The wavelength is 3472 nm.
