a clock battery wears out after moving 10,700 c of charge through the clock at a rate of 0.490 ma. (a) how long (in s) did the clock run?
To calculate the amount of time the clock ran, we can use the formula
time = charge / current
where charge is measured in coulombs (C), current is measured in amperes (A), and time is measured in seconds (s).
Given that the clock moved 10,700 C of charge at a rate of 0.490 mA, we can plug these values into the formula
time = 10,700 C / (0.490 mA / 1000) A
We convert the current from mA to A by dividing by 1000, since 1 A = 1000 mA.
time = 10,700 C / 0.490 A = 21857.142857142857 s
So the clock ran for approximately 21857.14 seconds or around 6.1 hours.

Find the average velocity during each time period?Average velocity = (Displacement)/(Time Period)For example, if the displacement during the period from 0 seconds to 5 seconds is 10 cm, then the average velocity during that period would be 2 cm/s:Average velocity = (10 cm)/(5s) = 2 cm/sThis is known as the average velocity equation, and it is given by: v_avg = (x_f - x_i)/(t_f - t_i)where x_f and x_i are the final and initial displacement of the particle respectively, and t_f and t_i are the final and initial time, respectively. Therefore, for a given time period, the average velocity is equal to the change in displacement over the change in time. For example, if the displacement of the particle is given by the equation of motion , where is measured in seconds, and the time period is given by seconds, then the average velocity during this period can be calculated as follows:v_avg = (x(t_f) - x(t_i))/(t_f - t_i)

a water wave has a frequency of 0.20 hz. how many wavelengths will have passed a fixed point after 1.5 min? (9.1)
a water wave has a frequency of 0.20 hz. 18 wavelengths will have passed a fixed point after 1.5 minutes.
To calculate the number of wavelengths that have passed a fixed point after a given time, we need to find the distance traveled by the wave and divide it by the wavelength.
First, we need to convert the time from minutes to seconds:
1.5 min = 90 sec
Next, we can find the distance traveled by the wave using the formula:
distance = velocity * time
where the velocity of a water wave is given by the equation:
velocity = frequency * wavelength
In this case, the frequency is 0.20 Hz and the wavelength can be calculated as follows:
wavelength = velocity / frequency
Substituting the values, we get:
wavelength = (0.20 Hz * velocity) / frequency = velocity / frequency
Therefore, the distance traveled by the wave can be calculated as:
distance = velocity * time = (0.20 Hz * wavelength) * 90 sec = 18 * wavelength
Finally, the number of wavelengths that have passed a fixed point after 1.5 minutes is calculated as:
number of wavelengths = distance / wavelength = 18 * wavelength / wavelength = 18
Therefore, 18 wavelengths will have passed a fixed point after 1.5 minutes.

separated by 0.10 m and particles q2 and q3 are
separated by 0.15 m. What is the net force on
particle q1?
Answer:
Explanation:
To find the net force on particle q1, we need to calculate the force between each pair of particles and then add them together. The force between two particles is given by Coulomb's law:
F = k * (q1 * q2) / r^2
where F is the force, k is the Coulomb constant (approximately 8.99 x 10^9 N*m^2/C^2), q1 and q2 are the charges of the two particles, and r is the distance between them.
The force between q1 and q2 is:
F = 8.99 x 10^9 N*m^2/C^2 * (8.0 uC * 3.5 uC) / (0.10 m)^2
The force between q2 and q3 is:
F = 8.99 x 10^9 N*m^2/C^2 * (3.5 uC * -2.5 uC) / (0.15 m)^2
The net force on particle q1 is the sum of the two forces, which can be positive, negative or zero, depending on the direction of the force.
It's important to note that this calculation is based on the assumption that the charges are point charges, and that the forces are acting along a straight line. In real-world situations, charges are usually distributed over a certain volume, and the forces acting on the charges can be affected by various factors such as the presence of other charges or conducting materials, which can change the net force.

What is engine?An engine is an mechanical device that converts energy into useful work, typically in the form of rotational force. Engines are used in a variety of applications, from cars and airplanes to power plants and generators.
b. The acceleration the plane experiences during take-off can be calculated using Newton's Second Law of Motion, which states that Force = Mass x Acceleration. Therefore, the acceleration is 563,140 N / 369,000 kg = 1.53 m/s2.
c. To calculate the time it takes the plane to reach take-off speeds, we can use the kinematic equation for average acceleration, which states that the time taken is equal to the change in velocity (76 m/s) divided by the acceleration (1.53 m/s2). Therefore, the time taken is 49.8 seconds.
d. Using the kinematic equation for displacement, we can calculate the displacement the plane covers during take-off. This equation states that displacement is equal to the initial velocity (0 m/s) multiplied by the time taken (49.8 seconds) plus one-half of the acceleration (1.53 m/s2) multiplied by the time taken squared (49.8 seconds x 49.8 seconds).

A total lunar eclipse occurs when the Moon passes through the Earth's shadow, causing it to appear dark. This usually occurs at the time of a full moon, when the Earth is directly between the Sun and the Moon. After a total lunar eclipse, the Moon is still located on the opposite side of the Earth from the Sun. Consequently, the Moon will still appear half-illuminated, and can thus be viewed in its third-quarter phase the day after a total lunar eclipse.

what is fup , the magnitude of the force exerted upward on the bottom of the liquid?
FUP, the magnitude of the force exerted upward on the bottom of the liquid is equal to pressure times area.
In order to describe an object's maximal size and direction, we use magnitude. Scalar and vector quantities both use magnitude as a common link.
An object with mass can alter its velocity, or accelerate, as a result of a force. A force is the modification of an object's condition brought on by its surroundings. An object will be at stationary or moving as a result of forces. Think of a ball lying still on the ground as an illustration. You must exert considerable force on the ball in order to shift it in any way.

how to find least count of voltmeter if circuit element is 2.04 voltz
The least count is 0.01 of voltmeter if the circuit element is 2.04 Voltz
The circular scale for a micrometre has 50 divisions, and the smallest division on the main scale is 0.5 mm. Using the formula L.C = 0.5/50 = 0.01mm, we can calculate the least count.
As a result, the smallest least count in metres is 0.1 cm or 1 mm.
A voltage metre also referred to as a voltage metre, is a device that gauges the voltage or potential difference existing between two points in an electrical or electronic circuit. Direct Current (DC) or Alternating Current (AC) circuits are typically the two types of circuits that the voltmeter is used for.
Millivolt, kilovolt, and volt are the voltmeter's measurement units. The three most common units are these three. One volt is equal to 1,000 kilovolts and 0.001 millivolts.

How much energy (in Joules) does it take to melt 1 kg of ice? How much energy (in Joules) does it take to raise 1 kg of water by 50oC? Which number is greater? Latent heat for water = 3.33 x 10^5
It takes334kJ to melt 1 kg of ice and 210kJ to raise 1 kg of water by 50oC when the ice is converted to water at 0oC and then the water is raised to 50oC.
Given the mass of ice (m) = 1kg = 1000g
Latent heat of water (Lw) = 3.33 x 10^5
Here, the heat is required to melt the ice. So,
The latent heat of fusion of ice (Li) = 334 kJ/kg
We know that, Q = mLf (melting/freezing) where Lf is latent heat of fusion
Qi = 1kg x 334 kJ/kg = 334kJ
Hence, the energy required to melt 1kg of ice is 334kJ
Given temperature (T) = 50oC
To raise 1kg of water to vapor we need latent heat of vaporization which is the Latent heat of water.
Q = mcΔT where c is the specific heat and ΔT is change in temperature.
When the ice is converted to water the temperature is 0oC.
Q = 1000g x 4.2J/g x (50 - 0)
Q = 210kJ
Hence, the energy required to raise 1 kg of water by 50oC is 210kJ
