Explanation:

The total momentum for the collision is conserved. Hence the final velocity of the  cart will be 15 m/s.

Momentum of a moving body is ist product of mass and velocity. It is a vector quantity and having both magnitude and direction.

The total momentum in a collision is conserved. Thus, the sum of initial momentum of the two bodies will be equal to the final momentum of the combined mass.

Hence, M 1 V1 + M2 V2 = (M1 + M2) V

Where V is the final velocity.

Given that the mass the cart = 3.4 kg

velocity = 23.9 m/s

mass of the block  = 2 kg

initial velocity = 0 m/s.

(3.4 kg × 23.9 m/s ) +  (0) = (3.4 + 2 Kg) V

V =(3.4 kg × 23.9 m/s )/(3.4 + 2 Kg)

  = 15 m/s

Therefore, the velocity of their centre of mass is 15 m/s.

When the force on two charged spheres is tripled, the distance between them becomes approximately 3.16 cm.

Let's denote the initial distance between the charged spheres as \($d_1$\) and the final distance as \($d_2$\). According to Coulomb's law, the force between two charged spheres is inversely proportional to the square of the distance between them.

The relationship between the forces and distances can be expressed as:

\(\[\frac{F_2}{F_1} = \left(\frac{d_1}{d_2}\right)^2\]\)

where \($F_1$\) is the initial force and \($F_2$\) is the final force. Given that the force is tripled, we have:

\(\[\frac{3F_1}{F_1} = \left(\frac{d_1}{d_2}\right)^2\]\)

Simplifying the equation, we get:

\(\[3 = \left(\frac{d_1}{d_2}\right)^2\]\)

Taking the square root of both sides, we find:

\(\[\sqrt{3} = \frac{d_1}{d_2}\]\)

Rearranging the equation to solve for \($d_2$\), we have:

\(\[d_2 = \frac{d_1}{\sqrt{3}}\]\)

Substituting the initial distance of \($d_1 = 7.93$\) cm, we can calculate the final distance \($d_2$\):

\(\[d_2 = \frac{7.93}{\sqrt{3}} \approx 3.16 \text{ cm}\]\)

Therefore, when the force on each charged sphere is tripled, the distance between them becomes approximately 3.16 cm.

Answer:

18.6 Ω

Explanation:

Resistance = \(\frac{Voltage}{Current}\)

But first we have to find the current.

Current = \(\frac{Power}{Voltage}\)

Power = 0.37W

Voltage = 2.60V

∴ Current = \(\frac{0.37}{2.60}\)

= 0.14 ( 3 significant figures)

Now we can find the resistance.

Resistance = \(\frac{2.60}{0.14}\)

= 18.6 Ω ( 3 significant figures)

The best way to summarise the key results in a lab guide is by representing them through diagrams.

The important findings in a lab report are those that confirm or refute the working theories. Furthermore, other findings that are crucial to understanding the processes and/or mechanisms explored in the experiment may also be among the significant findings. The best way to summarise these results is by presenting them through diagrams o graphical presentation.

Key outcomes in an experiment can be findings that serve as stepping stones toward the trial's conclusion or findings that may not directly relate to the experiment itself but are nonetheless crucial to its success. A significant finding in an experiment is one that determines whether a hypothesis is accepted or rejected.

The truck's initial velocity is 80.0 km/h. When it hits the gravel patch, it experiences a negative acceleration of -5.0 km/h/s. This means that the truck's velocity will decrease by 5.0 km/h every second.

To find out how far the truck travels before slowing to 20.0 km/h, we need to use the equation:

v^2 = u^2 + 2as

Where v is the final velocity, u is the initial velocity, a is the acceleration, and s is the distance traveled.

First, we need to convert the units of the velocities and acceleration to m/s:

Initial velocity, u = 80.0 km/h = 22.22 m/s
Final velocity, v = 20.0 km/h = 5.56 m/s
Acceleration, a = -5.0 km/h/s = -1.39 m/s^2

Now we can plug these values into the equation:

(5.56)^2 = (22.22)^2 + 2(-1.39)s

Solving for s, we get:

s = (5.56)^2 - (22.22)^2 / 2(-1.39) = 346.8 m

Therefore, the truck will travel 346.8 meters before slowing down to 20.0 km/h.
Hi! I'd be happy to help you with this problem. We will use the following terms: truck, accelerate, and consider the scenario in less than 100 words.

1. Identify the given values:
Initial velocity (v0) = 80.0 km/h
Final velocity (vf) = 20.0 km/h
Acceleration (a) = -5.0 km/h/s

2. Use the formula vf² = v0² + 2*a*d to find the distance (d) traveled:
(20.0)² = (80.0)² + 2*(-5.0)*d

3. Solve for distance (d):
400 = 6400 - 10d
6000 = 10d
d = 600 km

The truck will travel 600 km before it slows to 20.0 km/h.

The lost volts in the battery are 0.0672 V. The current flowing through the resistors is 0.16 A.

Given values, Resistance R1 = R2 = R3 = 9.02 V Voltage, V = 4.4 V Internal resistance, r = 0.42 Ω(a) Calculating the current flowing through the resistors. The equivalent resistance, R in a series circuit is given by:

R = R1 + R2 + R3R

= 9.02 + 9.02 + 9.02R

= 27.06 Ω

We know that the current, I flowing through the circuit is given by:

I = V / (R + r)I

= 4.4 / (27.06 + 0.42)I

= 0.16 Ampere

Therefore, the current flowing through the resistors is 0.16 A.

(b) Calculating the "lost volts" in the battery. Lost volts in a battery can be found using the formula:

VL = I × rVL

= 0.16 × 0.42VL

The electric field strength inside the capacitor does not depend on the distance between plates. Hence, Potential difference and Electric field strength is  -234V and -1.8 x 10^5 V/m respectively.

The ability of electrical fields to pass through a conventional vacuum is represented by the physical constant known as the permittivity of free space. The constant has a relative standard uncertainty of 1.5 x 10-10 and is equal to around 8.854 x 10-12 F/m (farad per metre).

Q= charge =>  ± 0.708 nC

E => electric field strength = Q/Aεο

A=> area of plates 2.10x 2.10 cm2.

εο = > 8.854 x 10-12 F/m.

E= -0.708 x10^-9/ (2.1 x 2.1 x 8.854 x 10^-4 x 10^-12)

 =  -1.8 x 10^5 V/m.

Potential difference = Ed => -1.8 x 10^5 x 1.3 x 10^-3 => -2.34 x 10^2V
