We obtain a force of -1.5 x 10-1 N when we translate the response into scientific notation with two significant figures.

There are 1.5 x 103 metres between two clouds. The difference in charge between two clouds is 1.0 C for one and 5.0 C for the other. We can utilise Coulomb's law, which takes into account both the distance between the charges and the strength of their charges, to determine the force between them.

The equation provides us with an attraction or repelling force between the charges. In this instance, the result is a -0.15 N attractive force. As a result, the two clouds would be attracted to one another.

This is a landmark of anything so say like you see the water and you can see the relfated from the snow or the grass!

Explanation:

The ratio of angular velocity of the ball at end of the plane to its angular velocity (passing the center point C of the inclined plane) will be equivalent to "sqrt (5/2)."

The principle of conservation of energy can be applied here to determine the required ratio. As the ball rolls down the inclined plane, the potential energy it possessed at the top is transformed into kinetic energy as well as rotational energy.

Now, let's assume the ball has a mass 'm', a radius 'r', and an inertial moment of '\(I = (2/5)mr^{2}\)' (for a solid sphere). Let 'h' represent the height of the inclined plane's top and 'θ' represent the angle that the plane makes with the horizontal.

By applying the principle of conservation of energy, we get:

\(mgh = (1/2)I\omega^2 + (1/2)mv^2\)

where, \(mgh\) = potential energy of the ball at the top of the plane ('g' denoting acceleration due to gravity), \((1/2)I\omega^2\) = rotational kinetic energy ('ω' being the angular velocity), and \((1/2)mv^2\) denoting the translational kinetic energy ('v' is the linear velocity) of the ball.

On simplifying the equation, we get:

\(\omega f/\omega c = \sqrt{5r/h}\)

where \(\omega f\)= angular velocity of the ball at end of the plane, and \(\omega c\)  = angular velocity of the ball as it passes the center point C of the plane.

"sqrt (5/2)" is the correct option since it matches the expression obtained earlier, i.e., \(\omega f/\omega c = \sqrt{5r/h}\).

Answer:

You can describe the motion of an object by its position, speed, direction, and acceleration. An object is moving if its position relative to a fixed point is changing. Even things that appear to be at rest move.

Explanation:

Physics refers to a system as being in equilibrium when neither its internal energy state nor its state of motion tend to change over time.

If a simple mechanical body feels neither linear acceleration nor rotational acceleration, it is said to be in equilibrium. If nothing outside of this situation interferes with it, it won't alter. When all forces acting on a single particle are added up to zero, equilibrium is established. In addition to the aforementioned states, a rigid body particle is said to be in equilibrium if the vector sum of all torques operating on it equals zero, maintaining the body's constant state of rotational motion.

When minor, externally induced deviations from the equilibrium result in forces that have a propensity to counteract the deviation and bring the body or particle back to the equilibrium state, the equilibrium is said to be stable. Examples are a weight hung from a spring or a block resting flat on the ground.

Answer:

24.5 m/s

Explanation:

Since the work done by the electric field on the charge equals the kinetic energy of the ball, then

qV = 1/2mv²

and v = √(2qV/m)

where q = charge = + 0.05 C, V = potential difference = 12.0 V, m = mass of ball = 2.0 g = 0.002 kg

Substituting the values into v, we have

v = √(2 × + 0.05 C × 12.0 V/0.002 kg)

= √(1.2 CV/.002 kg)

= √(600 CV/kg)

The change in the momentum of the bus is 10600 kg-m/s, if bus of 1600 kg crashes with a SUV of 600 kg.

The mass of the bus, m₁ = 1600 kg

The mass of the SUV, m₂ = 600 kg

Initial velocity of the bus, v₁ = 10 m/s

initial velocity of the SUV, v₂ = 0 (at rest)

Velocity of the bus after collision, v₃ = 3 m/s

Velocity of the SUV after collision, v₄ = 1 m/s

The change in momentum(Δp) is given by,

Δp = (m₁v₁ + m₂v₂) - (m₁v₃ + m₂v₄)

Δp = (1600 × 10 + 600 × 0) - (1600 × 3 + 600 × 1)

Given that the actual speed of the car at the top of the hill is 20.0m/s. What is the reason for this difference in velocity?

Speed is a scalar quantity that is, it has only magnitude but no direction.

While velocity is a vector quantity, that is, it has both magnitude and direction.

If the actual speed of a car is 20 m/s, that is the magnitude of the speed only without direction.

Explanation:

I couldn’t find the answer to the question myself then found you, with no answer. So I guessed and failed my third question of the quiz, you were worth the sacrifice though ✨

The pair of waves could overlap to produce a wave with a higher amplitude through interference is that two waves of the same amplitude with crests that are perfectly aligned. Hence, option B is correct.

The maximum deflection or distance made by a point on even a vibrating object or wave relative to its equilibrium location is known as the amplitude in physics. It is equivalent to the length of a vibration path divided in half.

A pendulum's amplitude is therefore equal to the distance that the bob travels when swinging through one side to another. Vibrating sources produce waves, whose amplitude is inversely proportional to the source's amplitude.

The largest deviation of any place on the string out of its place when the line is at rest is used to determine the amplitude of a wave propagation, like the wave on such a plucked string.

Therefore, it concludes that option B is correct.

The solution to the differential equation is then:

x(t) = 0.25e⁽⁻⁶·⁰²⁵t⁾ cos(2.181t)

And the system is underdamped because the roots of the characteristic equation have a non-zero imaginary part.

The force required to stretch a spring is directly proportional to the amount the spring is stretched. This relationship is known as Hooke’s Law. It can be expressed mathematically as:

F = -kx

Where F is the force applied to the spring, x is the displacement of the spring from its equilibrium position, and k is the spring constant.

For a mass-spring system under the influence of a damping force, the differential equation governing the system is:

m(d2x/dt2) + c(dx/dt) + kx = 0

where m is the mass of the object attached to the spring, c is the damping coefficient, and k is the spring constant.

The given force of 2 lb stretches the spring by 1 ft, so the spring constant is given by k = F/x = 2/1 = 2 lb/ft.

The 8-lb weight is released 4 in. above the equilibrium position, which is 0.25 ft. The initial displacement is therefore x(0) = 0.25 ft, and the initial velocity is v(0) = 0. The damping force is given by f_d = -3/2v. Using the values given, the differential equation for the system is:

m(d2x/dt2) + c(dx/dt) + kx = 0 (1)

The values of m, k, and c are given by

m = 8/g = 8/32.2 = 0.248 kg

k = 2/lb/ft * 0.4536 kg/lb * 0.3048 m/ft = 0.294 kg/sm = 0.248 kgc = 3/2

The equation of motion is then:

d2x/dt2 + 12.05dx/dt + 1.186x = 0 (2)

where we have substituted the values of m, c, and k into equation (1).

The characteristic equation is:

r2 + 12.05r + 1.186 = 0 (3)

Solving for the roots of the characteristic equation, we find:

r = (-12.05 ± √(12.052 - 4(1.186)))/2= -6.025 ± 2.181i

The roots are complex conjugates, so the solution to the differential equation can be written as:

x(t) = e⁽⁻⁶·⁰²⁵t⁾(C₁ cos(2.181t) + C₂ sin(2.181t)) (4)

The initial displacement and velocity are given by x(0) = 0.25 and v(0) = 0.

Substituting these values into equation (4) and taking the derivative, we get:

x(0) = C₁ = 0.25dx/dt|t=0 = -6.025

C₂ = 0

Solving for C₁ and C₂, we get:

C₁ = 0.25C2 = 0

The solution to the differential equation is then:

x(t) = 0.25e⁽⁻⁶·⁰²⁵t⁾ cos(2.181t) (5)

The system is underdamped because the roots of the characteristic equation have a non-zero imaginary part.
