The total mass of the system after combustion is therefore 1Kg (ashes) + 9Kg (gases and water vapor) = 10Kg, which is the same as the total mass before combustion.

Therefore, if the mass of the logs before burning was 10Kg, the total mass of the system before combustion was 10Kg (logs) + 0Kg (oxygen) = 10Kg. After combustion, the mass of the ashes was 1Kg, so the mass of the remaining gases and water vapor released into the atmosphere was 10Kg - 1Kg = 9Kg.

There are three fundamental quantities in mechanics that are conserved. These are power, forward motion, and angular momentum.

An acrobat with a mass of 49-kg jumping on a trampoline, the force that the trampoline has to apply to accelerate her straight up at \(7.9m/s^2\) in newtons is 867.3 N.

How to calculate force? Force is the product of mass and acceleration.

Hence, F = ma

Where, F = Net force applied

            m = mass of an object

            a = net acceleration

Force can be calculated by multiplying the mass of the object with the acceleration experienced by it.

In this case, m = 49kg and a = \(7.9 m/s^2\)

Force applied by earth gravity on the acrobat is mg, which equals 49*9.8 N i.e., 480.2 N.

\(F - F_{gravity}=ma \\F-F_{gravity} = ma\\F = F_{gravity}+ma\\F=480.2+49*7.9 N \\F=867.3 N\\\)

So, F= 867.3 N is required.

Therefore, the trampoline has to apply a force of 867.3 N to accelerate the acrobat straight up at \(7.9 m/s^2\).

Answer:

Approximately 26.33 m/s.

Explanation:

We can apply one of the four kinematic equations:

\(\displaystyle \Delta d = \frac{1}{2}\left( v_f + v_i\right)t\)

Since the car slides to a stop after traveling 7.9 meters in 0.6 seconds, Δd = 7.9, t = 0.6, and v_f = 0. Substitute and solve for v_i:

\(\displaystyle \begin{aligned} (7.9 \text{ m}) &= \frac{1}{2}\left((0\text{ m/s}) + v_i)(0.6\text{ s}) \\ \\ v_i &=\frac{79}{3} \text{ m/s} \approx 26.33 \text{ m/s} \end{aligned}\)

In conclusion, the initial velocity of the car is about 26.33 m/s.

The amount of labor required by a pump to raise 5 m3 of water 20 meters and force it into the main at such a pressure head of 150 kpa is 1.73×10⁶ J.

Force applied across a distance is called work. Example of effort include dragging down a trapped helium balloon, driving down a hill, and lifting an item against the gravitational attraction of the Earth. Energy manifests mechanically as work. The joule (J), and coulomb (N m), is the accepted work unit.

W= (Effort to raise water) + ( Work to push it in )

A modulo-24 counter circuit needs at least five D flip-flops to count up to 24.

A modulo-24 counter circuit needs at least 5 D flip-flops. A D flip-flop, also known as a data or delay flip-flop, is a type of flip-flop that stores the value of the data input.

In a modulo-n counter, the counter's output will change state only when n pulses have been received. In other words, the counter cycles through n states before returning to its original state. For a modulo-24 counter, this implies that there will be 24 states before it repeats the original state.

The state diagram of the modulo-24 counter can be represented as follows:As a result, 24 is equivalent to 11000 in binary. Since there are five digits in 11000, the modulo-24 counter will require at least five D flip-flops.The main answer is that a modulo-24 counter circuit needs at least 5 D flip-flops.

In digital electronics, a counter circuit is used to generate binary numbers using a clock pulse. A counter circuit is a collection of flip-flops that are connected together to form a sequential circuit.

A sequential circuit is a circuit in which the output is dependent on the input and the state of the circuit. There are two types of sequential circuits: synchronous and asynchronous.In synchronous sequential circuits, the output is dependent on the input and the state of the circuit, and the clock is used to synchronize the operation of the flip-flops. The clock pulse controls the operation of the flip-flops.

The flip-flops are triggered at the rising or falling edge of the clock pulse.In asynchronous sequential circuits, the output is dependent on the input and the state of the circuit, but the clock is not used to synchronize the operation of the flip-flops. Instead, the flip-flops are triggered by the output of other flip-flops or external signals.In a counter circuit, the number of flip-flops required depends on the modulus of the counter.

The modulus is the number of states in the counter. For example, a modulus-16 counter has 16 states. A modulus-24 counter has 24 states. A modulus-32 counter has 32 states.A D flip-flop is a type of flip-flop that stores the value of the data input. In a counter circuit, the D flip-flops are used to store the count. The output of the counter is taken from the outputs of the flip-flops.

The conclusion is that a modulo-24 counter circuit needs at least five D flip-flops to count up to 24.

The planes must be flying because of earths gravity when two airplanes are flying in the sky in such a way that the gravitational attractions between them decreases.

In mechanics, gravity—also known as gravitation—is the constant force of attraction that pulls all matter together. It has no impact on determining the internal characteristics of common matter because it is by far the weakest known force in nature.

All objects on Earth experience weight, or a gravitational pull that is proportional to their mass and is imposed by the planet's mass. The acceleration that gravity gives to objects falling freely serves as a gauge of its strength. The acceleration of gravity at Earth's surface is approximately 9.8 meters per second. As a result, during free fall, an object's speed increases by about 9.8 meters per second. A freely falling body accelerates to about 1.6 m/s2 at the Moon's surface.

If the density of matter in the universe turned out to be greater than the critical density, it would imply that the universe is a closed system. This means that the gravitational pull of matter in the universe is strong enough to eventually halt the current expansion and cause the universe to collapse in on itself.

This collapse would lead to the formation of a singularity, similar to the Big Bang, from which a new universe could potentially emerge.

However, current observations suggest that the density of matter in the universe is actually less than the critical density, indicating that the universe is an open system. This means that the current expansion of the universe will continue indefinitely, potentially leading to a "heat death" scenario where all matter is evenly dispersed and the universe reaches a state of maximum entropy.

It is important to note that the actual density of matter in the universe is still a topic of ongoing research and debate, with various methods of measurement producing slightly different results.

Answer:

The frequency of the wave is 5 Hz

Explanation:

Wavelength is the minimum distance between two successive points on the wave that are in the same state of vibration. It is expressed in units of length (m).

Frequency is the number of vibrations that occur in a unit of time. Its unit is s – 1 or hertz (Hz).

The propagation velocity is the speed with which the wave propagates in the medium, that is, it is the magnitude that measures the speed at which the wave disturbance propagates along its displacement. Relate the wavelength (λ) and the frequency (f) inversely proportional using the following equation: v = f * λ.

In this case:

Replacing:

50 \(\frac{m}{s}\) = f* 10 m

Solving:

\(f=\frac{50 \frac{m}{s} }{10 m}\)

f=5 Hz

The frequency of the wave is 5 Hz

Answer:

11.44J/C

Explanation:

To find the electric potential for a point at 3m from one extreme of the bar you use the formula for the electric potential:

\(V=\int k\frac{dq}{r}=\int k\frac{dq}{x+3}\)

Where r = x+3 represent the 3m distance of the charge to a point x in the bar.

dq: differential of charge = λdx. λ is the linear charge density.

k: Coulomb constant = 8.98*10^9 Nm^2/C^2

You can write dq as λdx. Furthermore, If you assume that the other extreme of the bar is at origin of the x-axis you can write the integral as follow:

\(V=\int_{0}^{2}k\frac{\lambda dx}{x+3}\\\\V=k\lambda \ ln(x+3)|_{0}^{2}=k\lambda (0.510)\)

You replace λ ad k in the last expression:

\(V=(8.98*10^9Nm^2/C^2)(\frac{5*10^{-9}C}{2m})(0.510)=11.44\frac{J}{C}\)

hence, the electric potential is 11.44J/C

(a) The instantaneous source voltage can be determined by using the given magnitude and phase angle. Since the phase angle is 0°, the instantaneous source voltage can be written as:

V(t) = 277 * cos(2π * 60 * t)

(b) For a 30-Ω resistor, the current entering the positive terminal is the same as the source current. Since the voltage and resistance are given, we can use Ohm's law to determine the current:

I(t) = V(t) / R = (277 * cos(2π * 60 * t)) / 30

(c) For a 15-mH inductor, the phasor current can be determined using the formula:

I = V / jωL

where j is the imaginary unit (√(-1)), ω is the angular frequency (2π * frequency), and L is the inductance. In this case, ω = 2π * 60 and L = 15 * 10^(-3):

I = (277 ∠0°) / (j * 2π * 60 * 15 * 10^(-3))

To find the instantaneous current, we can take the real part of the phasor current and then convert it to the time-domain using cosine function:

I(t) = Re(I * e^(jωt))

(d) For a capacitor with 100 mF, the phasor current can be determined using the formula:

I = jωCV

where C is the capacitance. In this case, ω = 2π * 60 and C = 100 * 10^(-3):

I = (j * 2π * 60 * 100 * 10^(-3)) * 277 ∠0°

To find the instantaneous current, we can take the imaginary part of the phasor current and then convert it to the time-domain using sine function:

I(t) = Im(I * e^(jωt))

Answer:

Explanation:

Using the principle of conservation of energy, the potential energy is converted to kinetic energy, assuming any losses.

Kinetic energy is given by ½mv²

Potential energy is given by mgh

Where m is the mass, v is the velocity, g is acceleration due to gravity and h is the height.

Equating kinetic energy to be equal to potential energy then

½mv²=mgh

V

Making v the subject of the formula

v=√(2gh)

Substituting 9.81 m/s² for g and 20 m for h then

v=√(2*9.81*20)=19.799 m/s

Rounding off, v is approximately 20 m/s

Answer:

19.8 m/s

Explanation:

During the motion of a pemdulum bob, it casually converts kinetic energy to potential energy and vice versa.

A pendulum bob reaches its maximum speed at a position closest to its equilibrium position and has its lowest when it is farthest from the equilibrium position.

The maximum speed of a pendulum bob based on the mass involved and the maximum displacement from the equilibrium position is obtained from

Maximum kinetic energy = Maximum potential energy

Maximum potential energy occurs at the farthest point from equilibrium, that is,

P.E(max) = mgh

Maximum kinetic energy = ½mv²

½mv² = mgh

v = √2gh

g = acceleration due to gravity = 9.8 m/s²

h = farthest height from equilibrium position = 20 m

v = √(2×9.8×20) = 19.8 m/s
