A reservoir is in the shape of a circle of radius 2000 m. the water levels drops 2 cm over a period of a week. at what rate is the lake losing water?
Answers
The rate at which the lake is losing water is \(175.84 * 10^6m^3\) per week which is in the shape of a circle of radius 2000 m.
Given the radius of reservoir = 2000m
Height of water levels = 2cm
The equation to calculate the rate of water loss is V = \(\pi*r^2*h\), where V is the volume of water, r is the radius of the circle, and h is the height of the water. Now, we need to calculate the height of the water in order to calculate the rate of water loss. Since the water level dropped 2 cm over a week, we can calculate the total height of the water by multiplying the 2 cm by 7 days.
h = 2 cm * 7 days = 14cm
Now, we can plug in the values into our equation to calculate the rate of water loss.
\(V = \pi *(2000 m)^2*(14 cm)\)
\(V = \pi *(2000m)^2*14*10^{-2} = 175.84 * 10^6m^3\)
Therefore, the lake is losing \(175.84 * 10^6m^3\) of water per week.

The electron deflects downwards and strikes the bottom plate. The magnitude of the electric field between the plates is 4.0 x 10^2 N/C and separation between the charged plates is 2.0 cm. a.) Determine the horizontal distance traveled by the electron when it hits the plate. b.)Determine the velocity of the electron as it strikes the plate.
Answers
Answer:
Explanation:
Given that
speed u=4×10⁶ m/s
electric field E=4×10² N/c
distance b/w the plates d=2 cm
basing on the concept of the electrostatices
now we find the acceleration b/w the plates
acceleration a=qE/m=1.6×10⁻¹⁹×4×10²/9.1×10⁻³¹=0.7×10¹⁴=7×10¹³ m/s
now we find the horizantal distance travelled by electrons hit the plates
horizantal distance X=u[2y/a]^1/2
=4×10⁶[2×2×10⁻²/7×10¹³]^1/2
=9.5cm
now we find the velocity f the electron strike the plate
v²-(4×10⁶)²=2×7×10¹³×2×10⁻²
v²=16×10¹²+28×10¹¹
v²=1.88×10¹³m/s
speed after hits =>V=4.34×10⁶ m/s

which mechanism restricts the expression of leptin to adipocytes? only adipocytes contain:
Answers
The mechanism that restricts the expression of leptin to adipocytes is the fact that only adipocytes contain the specific gene and regulatory elements required for the production and secretion of leptin.
Leptin is a hormone primarily produced by adipose tissue (fat cells) and plays a crucial role in regulating energy balance and appetite. The gene responsible for producing leptin is called the LEP gene, and it is predominantly expressed in adipocytes. The regulatory elements within the gene control its expression and ensure that leptin is produced specifically in adipocytes. These regulatory elements can be influenced by various factors such as hormones, signaling pathways, and nutritional status.Due to this specific gene expression pattern, leptin is mainly synthesized and released by adipocytes, providing feedback signals to the brain about the body's energy stores. This mechanism allows for the precise regulation of leptin levels and its functions in maintaining energy homeostasis.

which relatively stable scale degree often resolves directly to the tonic?
Answers
The relatively stable scale degree that often resolves directly to the tonic is the fifth degree. The fifth degree is also known as the dominant scale degree, and it is one of the most essential elements of Western tonal music.
When a composer or songwriter wants to create a sense of resolution in a piece of music, they will often use the dominant chord, which is built on the fifth degree of the scale, to lead back to the tonic chord, which is built on the first degree of the scale. This is known as a V-I cadence, and it is one of the most common and effective ways to create a sense of closure in Western tonal music.In addition to its function as a dominant chord, the fifth scale degree is also used in a variety of other ways in Western music. For example, it is often used as a passing tone, connecting two other scale degrees in a melodic line. It can also be used as a pedal tone, where it is repeated over and over while other parts of the music change around it.Overall, the fifth scale degree is a crucial element of Western tonal music, and its stable and predictable nature makes it an excellent tool for composers and songwriters to use when they want to create a sense of resolution or closure in their music.

Describe how the pendulum concept is used in the pendulum clock.
Answers
The concept of the pendulum is used in pendulum clocks to keep time. The pendulum swings back and forth in a continuous motion at a fixed rate that is determined by the length of the pendulum and the force of gravity.
This motion is used to regulate the movement of the clock's gears, which control the hands on the clock face.The mechanism of a pendulum clock is such that when the pendulum swings in one direction, it pushes a toothed wheel or gear, which in turn moves the other gears, causing the clock's hands to move forward.
When the pendulum swings back in the opposite direction, it again pushes the gear, causing the hands to move further forward. This cycle continues, with each swing of the pendulum causing the hands to move forward by a set amount. The length of the pendulum determines the rate at which the hands move forward, with longer pendulums causing the hands to move more slowly.
In a pendulum clock, the pendulum swings back and forth in a continuous motion at a fixed rate that is determined by the length of the pendulum and the force of gravity. This motion is used to regulate the movement of the clock's gears, which control the hands on the clock face. The pendulum clock is an improvement on the original verge escapement clocks, which were prone to errors due to the uneven force of the mainspring.The pendulum is a simple yet effective device that can keep accurate time. Its motion is governed by the law of conservation of energy, which states that energy cannot be created or destroyed, only transferred from one form to another.
When the pendulum is pulled to one side and released, it swings back and forth, converting potential energy into kinetic energy and back again. The period of the pendulum, or the time it takes to complete one full swing, is determined by the length of the pendulum and the force of gravity. By adjusting the length of the pendulum, the rate at which it swings can be altered, allowing it to keep accurate time.
To keep the pendulum clock running accurately, it needs to be adjusted periodically. This is done by altering the length of the pendulum, either by moving a weight up or down along the pendulum rod or by turning a screw at the bottom of the pendulum bob. This alters the period of the pendulum, which in turn changes the rate at which the clock runs.
The pendulum clock is a testament to the ingenuity of humanity. By using the simple yet effective concept of the pendulum, clockmakers were able to create accurate timepieces that revolutionized the way we keep time. Today, the pendulum clock may have been superseded by more advanced technologies, but its legacy lives on in the modern clocks and watches we use every day.

To solve this problem, we can use the formula for the period of oscillation of a spring-mass system:
T = 2π√(m/k)
where T is the period of oscillation, m is the mass attached to the spring, and k is the spring constant.
We are given that T = 2.4 seconds and k = 100 N/m. Substituting these values into the formula, we get:
2.4 = 2π√(m/100)
Squaring both sides and rearranging, we get:
m = (100/4π²) × (2.4²) = 12.3 kg (rounded to one decimal place)
Therefore, the mass attached to the spring is 12.3 kg.
Hi! I'd be happy to help you with your question. To find the mass attached to the spring, we need to use the formula for the period of a spring-mass system: T = 2π√(m/k), where T is the period (time for one oscillation), m is the mass, and k is the spring constant.
In this case, the spring constant (k) is 100 N/m, and the period (T) is 2.4 seconds. We can rearrange the formula to solve for the mass (m):
m = (T^2 * k) / (4π^2)
Substitute the given values into the formula:
m = (2.4^2 * 100) / (4π^2)
m ≈ (5.76 * 100) / (39.48)
m ≈ 14.61

Explanation:
The starting temperature of the water, T₁ = 48F
The temperature at which the water boils, T₂ = 212°F
a. The difference between the initial and the boiling water temperature, ΔT = T₂ - T₁
Therefore;
ΔT = 212°F - 48°F = 164°F

b. 48°F = ((48 - 32)×5/9)°C = (80/9)°C = \(8.\overline 8 \ ^{\circ} C\)
212°F = ((212 - 32)×5/9)°C = 100°C
∴ ΔT = 100°C - \(8.\overline 8 \ ^{\circ} C\) = \(9.\overline 1 \ ^{\circ} C\)
c. The heat capacity of the water = The heat required to increase four quartz of water by 1 °C = 15.8 kJ
∴ The heat required to raise four quartz of water by \(9.\overline 1 \ ^{\circ} C\), ΔQ = 15.8 kJ/°C × \(9.\overline 1 \ ^{\circ} C\) = \(140.\overline 4\) kJ.
