The numerical value of the density of a nucleus of atomic number A is determined as 2.29 x 10¹⁷ kg/m³.
Density of the nucleus
The density of the nucleus of atomic number A is calculated as follows;
ρ = m/V
where;
m is mass of the atom = 1.66 x 10⁻²⁷ kgr is radius of the atom = 1.2 x 10⁻¹⁵ m[tex]\rho = \frac{m}{V} \\\\\rho = \frac{m}{\frac{4}{3} \pi r^3} \\\\\rho = \frac{1.66 \times 10^{-27}}{\frac{4}{3} \pi (1.2 \times 10^{-15})^3} \\\\\rho = 2.29 \times 10^{17} \ kg/m^3[/tex]
Thus, the numerical value of the density of a nucleus of atomic number A is determined as 2.29 x 10¹⁷ kg/m³.

when there is a constant unbalanced force applied in the opposite direction as the motion what will happen to speed and acceleration
Answer:
speed will be constant and so no acceleration
Explanation:
the body will move toward the weaker force, but since the forces are constant there will be no acceleration.
A 5.00 cm tall object is placed a distance of 24 cm from a convex lens. If the image is
formed 48 cm from the lens, determine the type and height of the image?
Answer.:
Explanation:
The image is either virtual or real and the height of the image is 10cm.
To find the image type and its height, we need to know about the magnification of convex lens.
What is magnification of an image formed by lens?magnification of an image is the comparison of the image size with respect to that of object.It's the ratio of image height to that of object height.What is the mathematical formula of magnification of image?Mathematically, the magnification of an image isHeight of image/height of object or image distance(V) / object distance(U)
If the magnification is positive, image is virtual and if it's negative, the image is real.What is the magnification, if image distance is 48cm and object distance is 24 cm?Object is placed on the left of the lens and the object distance is taken as negative using sign convention.If the image is also formed on the left, the image distance is taken as negative. Corresponding magnification is -48cm/-24cm = 2. Since, the magnification is positive, so, image is virtual.But, if the image is formed on the right of the lens at 48cm, the image distance is taken as positive. So the magnification is 48cm/(-24)cm = -2. Since, the magnification is negative, so image is real.What is the image height, absolute value of magnification is 2 and object height is 5cm?Magnification = image height / object heightSo, image height = magnification × object height
= 2×5 = 10 cm
Thus, we can conclude that the image is virtual if it's formed on the left of the lens and is real if it's formed on the right of the lens. The height of the image is 10 cm.

At what voltage can a 10 μF capacitor be energized to 0.45 J?
Given :
Capacity of capacitor is, [tex]C = 10\ \mu F[/tex].
To Find :
At what voltage can a 10 μF capacitor be energized to 0.45 J.
Solution :
We know, energy in capacitor is given by :
[tex]E = \dfrac{CV^2}{2}[/tex]
So,
[tex]V = \sqrt{\dfrac{2E}{C}}\\\\V = \sqrt{\dfrac{2\times 0.45}{10}}\ \mu V\\\\V = 0.3 \ \mu V[/tex]
Therefore, voltage required is [tex]0.3 \ \mu V[/tex] .

If a bird lands on a tree, is that an example of speed, velocity, or acceleration?
If a train starts from rest and after 0.5 hours travels at a speed of 75 km/hr, what is its
acceleration?
Answer:
150 km/hr²
Explanation:
The data for the motion of the train includes;
The train starts from rest, therefore, the initial velocity of the train, u = 0 km/hr
The speed of the train after 0.5 hours, v = 75 km/hr
The change in time during the motion of the train, Δt = 0.5 hours
The acceleration, 'a', is the rate of change of velocity with time;
[tex]a = \dfrac{\Delta v}{\Delta t} = \dfrac{v - u}{\Delta t}[/tex]
Therefore, we have;
a = (75 km/hr - 0 km/hr)/(0.5 hr) = 150 km/hr²
a = 150 km/hr² = 150 km/hr² × 1,000 m/km × hr²/(3,600 s)² = 5/432 m/s²
The acceleration of the train, a = 150 km/hr² = 5/432 m/s².
Integrated circuits are used in virtually all modern electronic
devices to carry out specific tasks.
TRUE
FALSE
Answer:
True.
Explanation:
An electric circuit can be defined as an interconnection of electrical components which creates a path for the flow of electric charge (electrons) due to a driving voltage.
Generally, an electric circuit consists of electrical components such as resistors, capacitors, battery, transistors, switches, inductors, etc.
This electrical network which is usually a closed loop comprises of a device that provides the energy (voltage) to drive electrons or electric current; the device is referred to as a source such as a generator or battery.
Similarly, an integrated circuit (IC) also referred to as microchip can be defined as a semiconductor-based electronic component that comprises of many other tiny electronic components such as capacitors, resistors, transistors, and inductors.
Generally, integrated circuits (ICs) are used in virtually all modern electronic devices to carry out specific tasks or functions such as amplification, timer, oscillation, computer memory, microprocessor, etc.
The fact that quasars can be detected from distances where even the biggest and most luminous galaxies cannot be seen means that Select one: A. they must be in directions where intergalactic absorption by dark matter is minimum, allowing us to see them. B. they must be intrinsically far more luminous than the brightest galaxies. C. they have not been as redshifted by their motion as have galaxies, and hence they can still be seen. D. they must be in directions where gravitational focusing by the masses of nearer galaxies makes them visible from Earth.
Answer:
B. they must be intrinsically far more luminous than the brightest galaxies.
Explanation:
Quasar is famous for being an intergalactic object which is billions of years away from the earth yet can still be seen, unlike the other star body, unlike giant galaxies.
Hence, the fact that quasars can be detected from distances where even the biggest and most luminous galaxies cannot be seen means that "they must be intrinsically far more luminous than the brightest galaxies."
This condition, including other related evidence gotten in recent years concerning our galaxy, has shown that quasars are probably the central nuclei of very distant, very active galaxies.

A charged particle is placed in an external magnetic field and it is moving in a circular path of radius 26m.The magnetic force acting on the particle is 16N.What is the kinetic energy of the particle
Answer:
208 Joules
Explanation:
The radius of the circular path the charge moves, r = 26 m
The magnetic force acting on the charge particle, F = 16 N
Centripetal force, [tex]F_c[/tex] = m·v²/r
Kinetic energy, K.E. = (1/2)·m·v²
Where;
m = The mass of the charged particle
v = The velocity of the charged particle
r = The radius of the path of the charged particle
Whereby the magnetic force acting on the charge particle = The centripetal force, we have;
F = [tex]F_c[/tex] = m·v²/r = 16 N
(1/2) × r × [tex]F_c[/tex] = (1/2) × r × m·v²/r = (1/2)·m·v² = K.E.
∴ (1/2) × r × [tex]F_c[/tex] = (1/2) × 26 m × 16 N = = (1/2)·m·v² = K.E.
∴ 208 Joules = K.E.
The kinetic energy of an particle moving in the circular path, K.E. = 208 Joules.

light waves with a frequency of 7.26 x 10^14 HZ lies in the violet region of the visible spectrum. what is the wavelength of this frequency of light?
Answer:
4.13×10⁻⁷ m
Explanation:
Applying
v = λf................... Equation 1
Wherfe v = speed of light, λ = wavelength of light, f = frequency of light.
make λ the subject of the equation
λ = v/f....................... Equation 2
Note: Light is an electromagnetic wave, and all electromagnetic wave moves with thesame speed which is 3×10⁸ m/s.
From the question,
Given: f = 7.26×10¹⁴ Hz
Constant: v = 3×10⁸ m/s
Substitute these values into equation 2
λ = (3×10⁸)/(7.26×10¹⁴)
λ = 4.13×10⁻⁷ m

do transistors amplfy a.c or d.c
Explanation:
thet amplify DC, because of the voltage ( small current input signal)
Answer:
Yes,by using direct coupling(transistors) amplifier we will amplify low frequency (DC) signals. A transistor is certainly capable of taking a small-current input signal and controlling a high-current output at the same voltage, thereby amplifying the power of the input signal whether it's AC or DC.
