Yes, a=f/m where a is the acceleration, f is the force, and m is the mass of an object,  a=0.2m/s^2

According to Newton's 2nd law of motion, According to this law, the rate of change of linear momentum of a body is directly proportional to the external force applied on the body, and this change takes place always in the direction of the force applied. In simple terms, it means that a larger force will change the momentum of an object more quickly as compared to a smaller force.

Mathematically, we can write

F∝ dp/dT

where p is the momentum

F∝ (mv-mu)/t₂-t₁

where v is the final velocity and u is the initial velocity

Now, F∝{m(v-u)}/(t₂-t₁)

         F∝ma                       [∵ a=(v-u)/t]

         F=kma

∴  when k=1

  F=ma

Now according to this question,

f=10,000 N    and     m=50,000kg

By applying the formula,

F=ma

10,000=50,000*a

∴ a= 10,000÷50,000

a=0.2  or 2×10⁻¹ m/s²

The amount of charge that can be placed on a capacitor depends on the capacitance, which is determined by the area of each plate.

The capacitance of a capacitor is given by the formula:

C = ε0 * (A / d)

Where:

C is the capacitance,

ε0 is the permittivity of free space (a constant value),

A is the area of each plate,

d is the separation between the plates.

To determine the amount of charge, we can rearrange the formula as:

Q = C * V

Where:

Q is the amount of charge,

V is the voltage across the capacitor.

Given that the area of each plate is 7.3 cm², we can use this information to calculate the capacitance. However, the question does not provide the voltage or any other information required to calculate the amount of charge accurately. Without knowing the voltage or other relevant parameters, it is not possible to determine the exact amount of charge that can be placed on the capacitor.

The correct answer is option B) 1.2A. According to Ohm's Law, current (I) is equal to voltage (V) divided by resistance (R). Therefore, for a voltage of 12 volts and a resistance of 10 ohms, the current can be calculated.

To find the current for a voltage of 12 volts and a resistance of 10 Ohms, we will use Ohm's Law, which states that Voltage (V) = Current (I) * Resistance (R). We can rearrange the formula to find the current: I = V / R.

Given:
Voltage (V) = 12 volts
Resistance (R) = 10 Ohms

Now, calculate the current:
I = V / R = 12 volts / 10 Ohms = 1.2 A

So, the current is 1.2 A (Option B).

Now, let's define current, voltage, and resistance with their SI units:

1. Current (I): The flow of electric charge through a conductor, measured in Amperes (A).

2. Voltage (V): The electric potential difference between two points in a circuit, which causes the flow of current. It is measured in Volts (V).

at time t2, planet A is located 3/4 of a circle away from planet B or 270 degrees from its position at time t1.

Since A and B are orbiting a common star, they are both moving in circular orbits around the same center of mass. At time t1, A and B are perpendicular to each other or one-quarter of a circle apart, which means that they are separated by an angle of 90 degrees or pi/2 radians.

At time t2, planet B has moved through half a revolution, which means that it has traveled halfway around its circular orbit and is now on the opposite side of the star. Since the orbit is circular, this means that B has moved through an angle of pi radians or 180 degrees.

To determine the position of planet A at time t2, we need to know the period of the orbits of A and B, which is the time it takes for each planet to complete one full orbit around the star. Let's assume that the periods of the two planets are equal and are denoted by T.

Since planet B has moved through half a revolution at time t2, it has traveled a distance of pi times the radius of its orbit. This distance is also equal to the distance that planet A has traveled in the same time interval since both planets have the same period. Therefore, the angle between A and B at time t2 is equal to the angle between them at time t1 plus the angle that B has traveled in the time interval between t1 and t2.

Using the fact that B has traveled an angle of pi radians in the time interval, we can write:

the angle between A and B at time t2 = pi/2 + pi = 3*pi/2

Therefore, at time t2, planet A is located 3/4 of a circle away from planet B or 270 degrees from its position at time t1.

The temperature in Kelvin (K) is equal to the temperature in Celsius (°C) plus 273.15.

The Celsius and Kelvin temperature scales are two common temperature scales used in science. The relationship between these two scales can be described by a simple equation.

To convert a temperature from Celsius to Kelvin, you add 273.15 to the Celsius temperature. This equation is derived from the fact that the Kelvin scale starts at absolute zero, which is -273.15°C. Therefore, to account for the offset between the two scales, 273.15 is added to the Celsius temperature to obtain the equivalent temperature in Kelvin.

For example, if you have a temperature of 25°C, you can convert it to Kelvin by adding 273.15:

25°C + 273.15 = 298.15 K

So, 25°C is equivalent to 298.15 K.

This equation holds true for any temperature value in Celsius. By adding 273.15 to a Celsius temperature, you obtain the corresponding temperature in Kelvin.

In summary, the equation K = °C + 273.15 represents the conversion between Celsius and Kelvin temperatures, where K represents the temperature in Kelvin and °C represents the temperature in Celsius. Adding 273.15 to a Celsius temperature gives the equivalent temperature in Kelvin.

Since the dimensions of both the sides are equal, the equation is correct.

Dimensions are the physical measurements of a space or object. They are used to describe the size, shape, and proportions of an object. Dimensions can be measured in length, width, height, depth, and other factors. Length is the longest side of an object or space, width is the shorter side, and height is the measurement from the highest point to the lowest point.

Dimensional analysis:

Given equation: h = 1/2 g t

Let us check the dimensions of each side.

Left hand side, [h] = [length]

Right hand side, [1/2 g t] = [M L T-2 T] = [M L T-2]

Since the dimensions of both the sides are not equal, the equation is incorrect.

The correct equation with the help of dimensions is:

h = 1/2 g t2

Left hand side, [h] = [length]

Right hand side, [1/2 g t2] = [M L T-2 T2] = [M L T-2]

Since the dimensions of both the sides are equal, the equation is correct.

Ernest Rutherford observed that particles with a positive charge deflected when passing through a thin sheet of gold foil, concluding that the atom's positive part is small and dense.

Explanation:

The Ernest Rutherford experiment describes planetary model of an atom. According to the model, an atom has a tiny, compact, positively charged centre called a nucleus, where almost all of the mass is concentrated, while light, negatively charged particles called electrons orbit far around it, much like planets orbit the Sun. In his experiment, the observation that a positive charge is deflected through a thin sheet of gold foil led to the conclusion that the deflection some of the positive charge occurs in a small region of the atom.

Gauge pressure is the pressure measured relative to atmospheric pressure. A commonly used instrument for measuring gauge pressure is the pressure gauge.

A pressure gauge typically consists of a circular dial with a pointer, a pressure sensing element, and a scale. The sensing element, which is usually a diaphragm or a Bourdon tube, is connected to the system or container whose pressure is being measured.

The pressure gauge is usually connected to the system or container through an inlet port. When the pressure in the system or container changes, it exerts a force on the sensing element of the pressure gauge. This force causes the sensing element to deform, which in turn moves the pointer on the dial. The position of the pointer on the pressure scale indicates the gauge pressure.

The pressure scale on the dial is calibrated in units such as psi (pounds per square inch), bar, or kPa (kilopascals), depending on the application and region. The scale allows the user to directly read the gauge pressure value.

It's important to note that the pressure gauge measures the difference between the pressure being measured and the atmospheric pressure. If the system or container is under vacuum (pressure lower than atmospheric pressure), the gauge will indicate negative values.

Pressure gauges are widely used in various industries and applications where monitoring and control of pressure is essential, such as in industrial processes, HVAC systems, pneumatic systems, and hydraulic systems.

Explanation:

Draw a diagram. Put the two cells in series. Now draw 3 resistors. Two of them equal 0.26 ohms each. The third one is the lightbulb which is 12 ohms.

R = 0.26 + 0.26 + 12 = 12.52

The bulb has a voltage of 2.88 volts across it. You can get the current from that.

i = E / R

i = 2.88 / 12 =

i = 0.24 amps.

Now you can get the voltage drop across the two cells.

E = ?

R = 0.26

i = 0.24 amps

E = 0.26 * 0.24

E = 0. 0624

Finally divide the 2.88 by 2 to get 1.44

Each cell has an emf of 1.44 + 0.0624 = 1.5024

While both the rubbing stuff and batteries involve the generation and use of electrical energy, they differ in their underlying mechanisms and practical applications.

When it comes to comparing the rubbing stuff to a battery, there are a few key differences to consider. Firstly, the rubbing stuff, which is often referred to as static electricity, is generated through friction between two different materials.

This process creates a build-up of electrical charges, which can then be discharged through a spark or shock. In contrast, a battery generates electricity through a chemical reaction between two different materials, typically a metal and an electrolyte.

Another key difference is that while the rubbing stuff is often a temporary phenomenon, as the charges will dissipate over time, a battery can provide a continuous source of power as long as it has sufficient charge.

Additionally, a battery can be recharged and reused, whereas the rubbing stuff is generally a one-time occurrence.
