Answer: 2 cm
Explanation:
Given , for a converging lens
Focal length :
Height of object :
Object distabce from lens :
Using lens formula: , we get
, where v = image distance from the lens.
On solving aboive equation , we get
Formula of Magnification : , where h' is the height of image.
Put value of u, v and h in it , we get
Hence, the height of the image is 2 cm.
Answer:
The density of the woman is 950.8 kg/m³
Explanation:
Given;
fraction of the woman's volume above the surface = 4.92%
then, fraction of the woman's volume below the surface = 100 - 4.92% = 95.08%
the specific gravity of the woman
The density of the woman is calculate as;
Density of fresh water = 1000 kg/m³
Density of the woman = 0.9508 x 1000 kg/m³
Density of the woman = 950.8 kg/m³
Therefore, the density of the woman is 950.8 kg/m³
Answer:
Momentum,
Explanation:
The wave function of a particle is given by :
...............(1)
Where
x is the distance travelled
t is the time taken
k is the propagation constant
is the angular frequency
The relation between the momentum and wavelength is given by :
............(2)
From equation (1),
Use above equation in equation (2) as :
Since,
So, the x-component of the momentum of the particle is . Hence, this is the required solution.
Answer:
L = 22.97 H
Explanation:
Given that,
Capacitance,
Oscillation frequency, f = 0.5 Hz
The frequency of an AC circuit is given by :
Where
L is impedance
So, the impedance of LC circuit 22.97 H.
