The charge on each particle is approximately ±6.41×10⁻⁷ C. Particle A has an initial acceleration of 7 m/s², while Particle B has an initial acceleration of 10 m/s².

To calculate the charge on either particle, we can use Newton's second law of motion and Coulomb's law.

First, let's consider particle A. We know its initial acceleration is 7 m/s² and its mass is 5×10⁻⁷ kg. Applying Newton's second law (F = ma), we can calculate the net force acting on particle A.

F = m × a

F = (5×10⁻⁷ kg) × (7 m/s²)

F = 3.5×10⁻⁶ N

Next, we can apply Coulomb's law to determine the force between the two particles.

Coulomb's law states that the force between two charged particles is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.

F = k × (q₁ × q₂) / r²

Since the particles have equal charges, we can denote the charge on each particle as q.

F = k × q² / r²

Combining both equations, we have:

3.5×10⁻⁶ N = k × q² / (3.4×10⁻³ m)²

Now, we need the value of the Coulomb constant, k, which is approximately 8.99×10⁹ Nm²/C².

Simplifying the equation, we have:

3.5×10⁻⁶ N = (8.99×10⁹ Nm²/C²) × q² / (3.4×10⁻³ m)²

Solving for q², we get:

q² = (3.5×10⁻⁶ N) × (3.4×10⁻³ m)² / (8.99×10⁹ Nm²/C²)

Calculating the right side of the equation gives us:

q² ≈ 4.10×10⁻¹³ C²

Taking the square root of both sides, we find:

q ≈ ±6.41×10⁻⁷ C

Therefore, the charge on each particle is approximately ±6.41×10⁻⁷ C. The sign indicates the type of charge, with the positive sign representing a positive charge and the negative sign representing a negative charge.

Answer:

The ratio of the time period of object 1 to the time period of object 2 is \(\frac{1}{4}\). (T₁ : T₂) = 1 : 4

Explanation:

Let suppose that both objects are moving along the circular paths at constant speed, such that period of rotation of each object is represented by the following formula:

\(\omega = \frac{2\pi}{T}\)

Where:

\(\omega\) - Angular speed, measured in radians per second.

\(T\) - Period, measured in seconds.

The period is now cleared:

\(T = \frac{2\pi}{\omega}\)

Angular speed (\(\omega\)) and linear speed (\(v\)) are related to each other by this formula:

\(\omega = \frac{v}{R}\)

Where \(R\) is the radius of rotation, measured in meters.

The angular speed can be replaced and the resultant expression is obtained:

\(T = \frac{2\pi\cdot R}{v}\)

Which means that time period is directly proportional to linear speed and directly proportional to radius of rotation. Then, the following relationship is constructed and described below:

\(\frac{T_{2}}{T_{1}} = \left(\frac{v_{1}}{v_{2}}\right)\cdot \left(\frac{R_{2}}{R_{1}} \right)\)

Where:

\(T_{1}\), \(T_{2}\) - Time periods of objects 1 and 2, measured in seconds.

\(v_{1}\), \(v_{2}\) - Linear speed of objects 1 and 2, measured in meters per second.

\(R_{1}\), \(R_{2}\) - Radius of rotation of objects 1 and 2, measured in meters.

If \(\frac{v_{1}}{v_{2}} = 2\), \(R_{1} = 10\,m\) and \(R_{2} = 20\,m\), the ratio of time periods is:

\(\frac{T_{2}}{T_{1}} = 2\cdot \left(\frac{20\,m}{10\,m} \right)\)

\(\frac{T_{2}}{T_{1}} = 4\)

\(\frac{T_{1}}{T_{2}} = \frac{1}{4}\)

The ratio of the time period of object 1 to the time period of object 2 is \(\frac{1}{4}\).

Therefore, the heat needed is 280.19 kCal.

Part B.

Given:

Where:

1 kCal = 0.00116 kWh

280.19 x 0.00116 = 0.327 kWh

13 x 0.327 = 4.251 ¢.

Therefore, the cost, if electrical energy were used, will be 4.251 ¢

Answer:

B:Jorge wanted to know where the apples were.

Explanation:

Explanation:

As the distance increases, the absolute value of the force decreases. Therefore, the correct answer is "increases; decreases". This is in accordance with Coulomb's Law, which states that the force between two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. As the distance between the charges increases, the force between them decreases because the inverse square relationship causes the force to weaken rapidly with distance.

The distance traveled in a unit of time is referred to as speed. The meter per second (m/s) is a SI unit. Any mathematical operation must be performed while maintaining the same units for all terms. If the units are different, the result will be incorrect. Until and unless terms have the same units, we cannot perform mathematical operations on them.

The posed issue is based on the correlation between distance, time, and speed. We must convert km/hr into m/sec in order to convert the specified unit of speed into SI units. The required distance will then be determined using the formula for distance speed and time.

Boat speed in relation to water = 2 m/sec

Bronco the skydiver, whose mass is 80 kg experiences 200 N of air resistance and gravity pulls on him with 800 N. The acceleration of his fall  7.5 m/sec².

A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.

To find the acceleration,

   F = mg

   F = 80.(10)

   F = 800 N

   air resistance = 200 N

   Net force = F - air resistance

                = 800 - 200

                =  600 N

   600 = mass . acceleration

   600 = 80 . acceleration

   acceleration = 7.5 m/sec²

The driver has to maintain the speed of 133.3 km/h for second half of the race in order to average 100km/h.

In order to calculate average velocity, divide the change in position or displacement (x) by the time intervals (t) during which the displacement takes place. Depending on the displacement's sign, the average velocity can either be positive or negative. Meters per second (m/s or ms-1) is the SI measure for average velocity. By dividing the entire distance the body has traveled by the amount of time it took to cross that distance, the average speed formula can be calculated.

To complete the race in 1 hr => 100 km/hr in a 100 km

Driver is going 80 km/hr at half way marker (50m).

Time taken to cover 50m = 50 km * (1 hr/80 km) = 5/8 hour.

Explanation:

Given the following :

Height of aircraft = 10000m

Acceleration due to gravity (g) = 10m/s^2

Angle of projection (θ) = 60°

Height of aircraft = maximum height

Maximum height of a projectile:

H = (u^2sin^2θ) / 2g

Where H = height

u = initial velocity

10000 = [(usinθ)^2] / 2g

10000 = [(u * sin60°) ^2] / 2*10

10000 = (0.866 * u)^2 / 20

20 * 10000 = 0.749956 * u^2

200000 = 0.749956u^2

u^2 = (200000/0.749956)

u^2 = 266,682.31

u = √266,682.31

To solve a line cut by a transversal, use the properties of parallel lines, such as corresponding angles and alternate interior angles, to find the unknown angle measurements.

When a line is cut by a transversal, a number of simultaneous equations can be formed by using the properties of parallel lines. For example, the corresponding angles of the lines will always be equal, the alternate interior angles will be equal, and the consecutive interior angles will add up to 180 degrees. Using these properties, you can identify the unknown angle measurements. For example, if the measure of one of the corresponding angles is known, the measure of the other corresponding angle can be determined simply by using the fact that they are equal. Similarly, if one of the alternate interior angles is known, the other can be determined using the fact that they are equal.
