Answer:
The frequencies are 13.8 Hz, 75 Hz, 12 Hz and 63.8 Hz.
Explanation:
Given that,
The frequency in r.p.m
Suppose, we find the frequency in hz.
We know that,
One r.p.m is equal to the one divided by 60 Hz.
We need to calculate the frequency in Hz
Using formula for frequency in Hz
For f₁,
For f₂,
For f₃,
For f₄,
Hence, The frequencies are 13.8 Hz, 75 Hz, 12 Hz and 63.8 Hz.
Answer:
The angular magnification is
Explanation:
From the question we are told
The focal length is
The near point is
The angular magnification is mathematically represented as
Substituting values
Answer:
The phase of mitosis in the illustration is anaphase.
Explanation:
In this phase, the chromosomes separate and move to opposites sides of the cell to prepare for reconstruction and division. These separations are known as sister chromatids.
Answer:
The required equation is y(t) = -10.34 + 0.4t + 10.4e^(-0.038t)
The velocity is the first derivative of y(t)
The acceleration is the second derivative of y(t).
Explanation:
The required equation is found by taking the first and second derivative for velocity and acceleration respectively and setting the equations given to the boundary conditions given. The complete solution can be found in the attachment below.

Answer:
La densidad (más precisamente, la densidad de masa volumétrica; también conocida como masa específica), de una sustancia es su masa por unidad de volumen. El símbolo más utilizado para la densidad es la letra griega en minúsculas rho), aunque también se puede utilizar la letra latina D. Matemáticamente, la densidad se define como masa dividida por volumen: .m/V donde es la densidad, m es la masa y V es el volumen. En algunos casos (por ejemplo, en la industria del petróleo y el gas de los Estados Unidos), la densidad se define libremente como su peso por volumen unitario, aunque esto es científicamente inexacto – esta cantidad se llama más específicamente peso específico.
