A-

The diagram of the set up shows the book resting on a horizontal table top with the force of gravity acting on it.

B-

The force acting on the book before the force was applied with the pencil is the force of gravity.

The magnitude of the force of gravity is 2.5n (the weight of the book).

C-

The book is at rest due to the force of friction being equal to the force of gravity. The force of friction is opposing the force of gravity, preventing the book from moving.

D-

The diagram shows the sliding book with the force of friction opposing the applied force of 2n and the force of gravity acting on it.

E-

The acceleration of the book can be calculated by the force acting on it divided by the mass of the book.

a = (Fapplied - Ffriction) / m

a = (2 - 1) / 2.5 = 0.4 m/s^2

The velocity of the book can be calculated using the equation:

v = a * t

v = 0.4 * 1.5 = 0.6 m/s

The book will have a velocity of 0.6 m/s when the applied force has been acting on it for 1.5 seconds.

The distance of planet X from the sun is 8 times greater than that of planet Y.

The time period of a planet around the sun is directly proportional to the distance of the planet from the sun. The relationship between the time period and distance of a planet around the sun is given by the formula T^2 = k*r^3, where T is the time period, r is the distance of the planet from the sun and k is a constant.

Given that the time period of planet X around the sun is 8 times that of planet Y.

T_x = 8 * T_y

We can square the equation, we have:

T_x^2 = 8^2 * T_y^2

We can divide the above equation by the constant k, we have:

r_x^3 = 8^2 * r_y^3

We can take the cube root of both sides, we have:

r_x = (8^2 * r_y^3)^(1/3)

r_x = 8 * r_y

So the distance of planet X from the sun is 8 times greater than that of planet Y.

The centripetal acceleration of the car is 1.85 m/s²

The speed at which anything moves around a circle is known as its centripetal acceleration. Centripetal acceleration is the acceleration experienced by any object that is travelling in a circle and whose acceleration vector is directed toward the center of the circle.

To find the centripetal acceleration of the car, we can use this following formula:

Centripetal acceleration = v²/r

In this case, we are given that:

The time that car was taking = 5.5 s

The radius of the car (r) = 56 m

The velocity of the car (v) = distance : time = 56 m : 5.5 s = 10.18 m/s

Hence, the centripetal acceleration:

2. Materials X & Y are different materials.

3. Materials X & Y are electrical conductors.

Two wires of various metals are joined at each end to form a thermocouple, a temperature-measuring instrument. The junction that will be used to measure temperature is placed there, and the other junction is maintained at a lower temperature at all times. Potential difference is measured by a metre connected in the middle.

A thermocouple, also referred to as a "thermoelectrical thermometer," is an electrical component made up of two conductors that are not similar to one another and that come together to form an electrical junction. The Seebeck effect causes a thermocouple to generate a voltage that is temperature-dependent, and this voltage can be used to calculate the temperature. Temperature sensors that are commonly used are thermocouples.

Commercial thermocouples can measure a wide range of temperatures, are reasonably priced, interchangeable, and come with standardised connectors. Thermocouples don't need an external source of excitation and are self-powered, unlike the majority of other temperature measurement techniques. Accuracy is thermocouples' main drawback; it can be challenging to achieve system errors of less than one degree Celsius (°C).

When shooting a bow and arrow, the archer pulls back the string and flexes the bow, storing potential energy.

Potential energy is the energy stored in an object due to its position or configuration. This type of energy is the stored energy of an object, which can be released and transformed into other forms of energy, such as kinetic energy. Potential energy is associated with forces such as gravity, electrical, and chemical, which can cause a change in an object’s energy state. Examples of potential energy include a stretched bow and arrow, a roller coaster at the top of a hill, and a compressed spring.

This potential energy is then transferred to the arrow in the form of kinetic energy. The arrow is then put in motion by the archer and due to the force of the bowstring, work is done in the form of acceleration. The arrow is then released and the kinetic energy propels it towards the target.

The uncertainty of the force is 10 N and the uncertainty of the acceleration is 0.01 m/s². The mass of the beam is 250 kg and its uncertainty is 12.5%.

Using the Newton second law of motion:

F = ma

m = F/a

Where:

F = the applied force

m = mass

a = acceleration.

In this problem, the force = 100 N with uncertainly 10 N.

Hence, incorporating its uncertainty, we can write

F = ( 100 ± 10 ) N or in percentage F = 100 ± (10%) N

The acceleration is 0.4 m/s² and its uncertainty is 0.01 m/s²

Hence, we can write:

a =  ( 0.4 ± 0.01 ) m/s² or in percentage a =  0.4 ± (2.5% ) m/s²

The mass of the beam can be calculated as:

m = F/a

   = 100/0.4 = 250 kg

The rule for the uncertainty in calculated result is: If data are multiplied or divided, the percentage uncertainty of the result is equal to the sum of the individual data uncertainties.

Hence, the uncertainty of the calculated mass (in percentage) is:

10% + 2.5% = 12.5%.

Explanation:

the distance is easy. this is just the sum of the distances of the individual trips :

400 + 700 + 1200 = 2300 km

the displacement is trickier. this is the line of sight distance between the starting point of the first trip and the ending point of the last trip.

let's imagine a coordination grid with 1 km as unit size, and the starting point being the origin (0, 0).

so, then the trips subtract 400 units from y, then 700 units from x, and then further 1200 units from y.

so, the coordinates of the end point are (-700, -1600).

the displacement (straight distance from the origin) is then found by using Pythagoras

c² = a² + b² (c being the Hypotenuse, a and b the legs)

via the right-angled triangle of the coordinate differences to the origin :

displacement² = (-700)² + (-1600)² =

= 490000 + 2560000 =

= 3050000

displacement = sqrt(3050000) = 1,746.42492... km

The melting point range will be broader than expected. In this scenario, the melting point tube most likely affect a melting point measurement.

When too much sample is placed in the melting point tube, it can affect the measurement of the melting point in several ways. One of the most likely effects is that the melting point range will be broader than expected. This occurs because the excess sample in the tube will impede the heat transfer to the sample, causing the sample to melt over a wider temperature range. As a result, the temperature at which the sample begins to melt and the temperature at which it is completely melted will be farther apart, resulting in a broader melting point range

The small paper clip means the less strength of an electromagnet. Whereas large paper clip means higher strength of an electromagnet.

The measure of the magnet's strength can be accounted by counting the number of paper clips your electromagnet can lift. A specific quantity of mass can only be picked up by each electromagnet that is produced. More light things and fewer heavier ones are picked up by the electromagnet.

An electromagnet's or solenoid's magnetic field strength is determined by the coil's length L, current flow rate (in amps), and number (N) of turns.

The amount of paper clips held grows with the number of spins. This indicates that as the coil's turns rise, so does the magnet's strength.

Since paperclips are not magnetic by nature, they cannot be chained together on their own. The paperclips can, however, be momentarily magnetic by employing a magnet. A paper clip's steel can be easily magnetic, but it quickly loses its magnetism.

Velocity is a vector quantity. Velocity means how fast an object is changing its position. As a vector quantity, velocity is direction aware and can be noted as negative or positive value based on its direction. Velocity can be calculated by dividing an object displacement and the time the object moves. Velocity can be formulated as:

Velocity = Displacement : Time

Speed on the other hand, is a scalar quantity. Hence speed pay no attention to the direction of an object's movement. Speed is calculated by dividing an object's total distance over time. Speed only anwer how fast an object is moving.
