If you have a 16-bit adc, what is the smallest temperature change you can detect if the adc range is 10 v?

A sound is moving through the atmosphere at a velocity of 343 ms-1. The sound wave has a wavelength of 0.1 cm.

Longitudinal waves are what make up sound. Compressions and rarefactions are also present in longitudinal waves when they pass through any given medium. When particles travel in close proximity to one another, compression occurs, creating areas of intense pressure.

As with all waves, the relationship between the speed of sound (vw), its frequency (f), and its wavelength () is provided by vw=f. vw=(331m/s)T273K describes how the sound's velocity in the air relates to air temperature T. For any and all frequencies and wavelengths, vw is constant.

Hi there!

We can use the kinematic equation:

vf = vi + at

vf = final velocity (m/s)

vi  = initial velocity (m/s)

a = acceleration (m/s²)

t = time (sec)

Rearrange to solve for acceleration:

(vf - vi)/t = a

(30 - 25)/10 = 5/10 = 0.5 m/s²

Answer:

Explanation: vf-vi/t = a

a=30m/s -25 m/s/10 s

a =5m/s /10s

a =1/2 m/s²

Explanation:

The magnitude of the potential difference between two points located 1.2 m apart in a uniform 640 n/c electric field, if a line between the points is parallel to the field.

The magnitude of the potential difference (V) between two points in an electric field is the amount of energy required to move a unit charge from one point to the other. It is typically measured in units of volts (V) and can be calculated using the equation: V = E * d, where E is the electric field strength and d is the distance between the points. The direction of the potential difference can be determined by the direction of the electric field. The equal to the product of the electric field strength and the distance between the points.

Formula: V = E * d

V = 640 n/c * 1.2 m = 768 V

Answer:

No.

Explanation:

if it's in equilibrium then the torque or moment of inertia on both sides should cancel.

Torque is a vector quantity, force times distance.

When doing these, make sure your units are the same by changing centimeters to meters first.

Left side is 400N * (-2.5m) = -1000 Nm

Right side is 300N * (3.5m) = 1050 Nm

-1000 Nm + 1050 Nm does not equal zero so there's a torque on the teeter and it will rotate clockwise. The system is not yet in equilibrium.

Answer:

The energy an object has due to its motion is called kinetic energy

Explanation:

Factors Affecting Kinetic Energy: the kinetic energy of an object depends on both its speed and its mass.

Answer:

kinetic energy

Explanation:

In physics, the kinetic energy (KE) of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. The same amount of work is done by the body when decelerating from its current speed to a state of rest.

Answer:

Matter, Force

Explanation:

In scientific contexts, mass is the amount of "matter" in an object (though "matter" may be difficult to define) whereas weight is the force exerted on an object by gravity. Objects on the surface of the Earth have weight, although sometimes the weight is difficult to measure.

The final gravitational force will be 1/16th of the initial gravitational force. In other words, the gravitational force will decrease when the objects are moved from 1 meter apart to 4 meters apart.

The gravitational force between two objects depends on their masses and the distance between them. According to Newton's law of universal gravitation, the force is inversely proportional to the square of the distance between the objects and directly proportional to the product of their masses.

Let's assume that the masses of the objects remain constant. If the objects are initially placed 1 meter apart and then moved to a distance of 4 meters, we can calculate how the gravitational force changes.

The formula for the gravitational force is:

F = G * (m1 * m2) / r^2

Where:

F is the gravitational force between the objects.

G is the gravitational constant.

m1 and m2 are the masses of the objects.

r is the distance between the objects.

Assuming the masses and the gravitational constant remain constant, we can compare the initial and final gravitational forces.

Let's denote the initial force as F_initial and the final force as F_final. Using the formula above, we can calculate the ratio of the final force to the initial force:

F_final / F_initial = (G * (m1 * m2) / (4^2)) / (G * (m1 * m2) / (1^2))

                    = (1 / 16) / (1 / 1)

                    = 1 / 16

This decrease in the gravitational force is a result of the inverse square law. As the distance between the objects increases, the force weakens exponentially. In this case, the force decreases by a factor of 16 because the distance is quadrupled (from 1 meter to 4 meters).

The initial speed of a truck, u = 0

Acceleration of the truck, a = 0.3 m/s²

Distance moved, d = 150 m

Let the final speed of the truck is v. Using third equation of motion i.e.

\(v^2-u^2=2ad\\\\v=\sqrt{u^2+2ad}\)

Put all the values,

\(v=\sqrt{0^2+2\times 0.3\times 150}\\\\v=9.48\ m/s\)

or

v = 34.128 km/h

So, the final speed of the truck is equal to 34.128 km/h.

Statement:

The electric current passing through a conductor is directly proportional to the potential difference across its ends provided temperature and other physical conditions remain constant.

Explanation:

Current is directly proportional to voltage loss through a resistor. That is, if the current doubles, then so does the voltage. To make a current flow through a resistance there must be a voltage across that resistance. Ohm's Law shows the relationship between the voltage (V), current (I) and resistance (R).

V∝I or I∝V⇒V=IR.

Explanation:

Ohm's law states that the current through a conductor is proportional to the voltage across the conductor. This is true for many materials (including metals) provided the temperature (and other physical factors) remain constant. The constant of proportionality, R,R is the resistance and the unit is the ohm, with symbol \Omega,Ω. The relationship can be written as:

V, equals, I, R.

V=IR

where V,V is the voltage across the conductor and I,I is the current flowing through it. If a component is ohmic (it obeys Ohm's Law), then its resistance must be independent of current and voltage.

When a proton is removed from point A and an electron is placed at point B, the direction of the electric force will be from point B towards point A. The angle of this force relative to the x-axis would be 180 degrees, with counterclockwise as positive.

As the electron and proton have equal and opposite charges, the magnitude of the force between them will be the same as the magnitude of the force between the proton and the electron.

The magnitude of the force between the proton and electron can be determined by Coulomb's law, which states that the force is proportional to the product of the charges and inversely proportional to the square of the distance between them.

In other words, the magnitude of the two forces is equal, but the direction of the two forces is opposite.

The depth would a 3.0 MHz xdcr have an attenuation of 9db is 2 cm.

The attenuation of an ultrasonic transducer, typically measured in decibels, is the loss of signal strength due to the medium. This may include scattering, absorption, or reflection of the signal as it travels through the medium. The formula to calculate the attenuation is: Attenuation (dB) = (Frequency (MHz) * Distance (cm)) / 2. The ultrasonic transducer's frequency and the distance of travel determine the attenuation of the ultrasonic signal, the greater the frequency of the ultrasonic signal, the greater the attenuation.

The formula will reveal the depth to which the signal will be attenuated. The ultrasonic transducer's frequency is 3.0 MHz, and the attenuation is 9 dB. We can use the above formula to calculate the distance as follows:9 = (3.0 MHz * distance) / 2

Solving for distance gives us:Distance = (9 * 2) / (3.0 MHz) = 6 / 3.0 = 2 cm.

Therefore, a 3.0 MHz ultrasonic transducer will have an attenuation of 9 dB at a depth of 2 cm.
