A 5 kg ball moving to the right at a speed of 6 m/s strikes another 4 kg ball moving to the left at 5 m/s. What is the velocity of each ball after the collision? PLZZZZ ANSWERRRR IM LITERALLY IN MISERY

Answer:

Approximately \(5.76 \times 10^{-18}\; {\rm J}\) (by the external force that moved the electron.)

Explanation:

Let \(q\) denote the magnitude of a charge in an electric field of magnitude \(E\). The magnitude of the electrostatic force on that charge would be:

\(F = q\, E\).

In the electric field in this question, the magnitude of the electric force on the electron would be:

\(\begin{aligned}F &= q\, E \\ &= 1.6 \times 10^{-19}\; {\rm C} \times 600\; {\rm N \cdot C^{-1}} \\ &= 9.6 \times 10^{-17} \; {\rm N}\end{aligned}\).

Moving the electron to the other plate would thus require an external force of \(9.6 \times 10^{-17}\; {\rm N}\).

This force needs to be exerted over a distance of \(6.0\; {\rm cm}\) (\(6.0 \times 10^{-2}\; {\rm m}\).) The direction of the motion is the same direction as that of the external force. Thus, the work that needs to be done would be:

\(\begin{aligned}W &= F\, s \\ &\approx 9.6 \times 10^{-17}\; {\rm N} \times 6.0 \times 10^{-2}\; {\rm m} \\ &\approx 5.76 \times 10^{-18}\; {\rm J}\end{aligned}\).

The magnitude of the force of the wall on the ladder at the point of contact is 248 N.

The wall is being leaned on by a ladder. The frictional force and the normal force of the floor on the ladder are both at work at the base of the ladder. Due to the wall, there is a normal force at the top of the ladder. The center of the ladder is experiencing the effects of gravity.

For equilibrium, there must be a horizontal force operating someplace on the ladder that calls for an opposite normal reaction force on the wall. Friction at the ladder's base is the force acting horizontally on the ladder.

Given:

Mass \((M) = 100 kg\)

Ladder length \((l)= 4.0 m\)

Mass of ladder \((m)= 25kg\)

Angle \(\theta=56^o\)

Answer:

No, the coil will produce no flow of current or potential difference.

Explanation:

Magnetic field flux is the number of magnetic field line passing through a given area. It depends on the area and the magnetic field strength through this area. For electromagnetic induction to occur, there must be a constantly changing magnetic field. This is according to Faraday's law of electromagnetic induction that states that the induced EMF is directly proportional to the rate of change in flux ΔФ/Δt, and is also proportional to the number of turns on the coil. A changing magnetic field will lead to a break in the flux linkage, which induces current or potential difference on the coil. A stationary coil through a magnetic filed will therefore produce no electric flow of current or potential difference on the coil.

only statement A is true.

Among the given statements:

a. "Shock waves only occur in supersonic flows."

This statement is true. Shock waves are formed when an object or flow exceeds the speed of sound (supersonic speed).

In supersonic flows, the disturbances created by the object's motion cannot propagate ahead of it, resulting in a shock wave.

b. "The static pressure increases across a normal shock wave."

This statement is false. In a normal shock wave, the static pressure decreases across the shock wave.

The shock wave is characterized by a sudden increase in flow velocity and a corresponding decrease in static pressure.

This pressure decrease is a consequence of the conservation of mass, momentum, and energy principles across the shock wave.

Option C. f¯¹(x) = (5x + 3)/2

Explanation:

f(x) = (2x – 3)/5

We can obtain the inverse of the above equation as follow:

Let f(x) be y.

Therefore,

F(x) = (2x – 3)/5

y = (2x – 3)/5

Next, we shall interchange the position of 'y' and 'x'. This is illustrated below:

y = (2x – 3)/5

x = (2y – 3)/5

Next, we shall make y the subject of the expression. This is illustrated below below:

x = (2y – 3)/5

Cross multiply

2y – 3 = 5x

Rearrange

2y = 5x + 3

Divide both side by 2

y = (5x + 3)/2

Therefore, the inverse of

f(x) = (2x – 3)/5 is f¯¹(x) = (5x + 3)/2

Short arc welding is commonly used for root pass welding to prevent blow through and overheating at the weld joint. Because there is less drooping and suck back, short arc welding is also commonly used on root pass joints.

The first pass in any welding process that combines two pieces or members into one structure is referred to as the root pass.

Subsequent passes raise the weld depth to the desired thickness, resulting in the required strength. The first pass usually serves as the foundation for subsequent filler passes.

Given parameters:

Height = 44.8m

Time to drop  = 1.49s

Unknown:

Speed of drop = ?

Solution:

The is a speed problem.

Speed is one of the physical quantities. It is designated a scalar because it has magnitude but no directional orientation.

Speed is the distance divided by time.

In this problem distance is the same as the height of the drop.

  Mathematically;

            Speed  = \(\frac{distance}{time}\)

So, input the parameters and solve;

           Speed  = \(\frac{44.8}{1.49}\)   = 30.1m/s

The drop recorded a speed of 30.1m/s

The result is ,(a)  Z = sqrt((10^2) + (15^2)) = 18.03 ohms.
                    (b) the apparent power would be S = (120 V) x (1 A) = 120 VA.

To find the apparent power (total volt-amps) of a series circuit with a 10 ohm resistor and 15 ohms of inductive reactance in a single inductor, we first need to calculate the impedance of the circuit.

Impedance is the total opposition to current flow in an AC circuit and is a combination of resistance and reactance. In this case, we can use the formula Z = sqrt(R^2 + XL^2), where R is the resistance and XL is the inductive reactance.

To find the apparent power (S) of the circuit, we use the formula S = Vrms x Irms, where Vrms is the root mean square voltage and Irms is the root mean square current. Since we are not given any values for voltage or current, we cannot find the exact value of apparent power.

If the truck is moving with the same velocity, if the mass is cut in half then the momentum of the truck will also reduce to half.

The momentum of a body can be described as the function of the object's mass and velocity. Momentum (p) can be determined as kinetic energy and is the product of velocity (v) and mass (m).

The momentum of an object can be determined from the mathematical formula:

p = m×v

The momentum of an object is conserved and can be equal to zero if the object is stationary and its velocity of an object is zero.

Given, the truck has a momentum, p = 5000 units

Given that the mass of the truck is reduced to half. Then the new mass of the truck is equal m/2.  If the truck is still moving with the same velocity then the momentum is equal to:
