Here's a C program that takes three integers as input and finds the maximum and minimum values among them:

An integer  is a whοle number (nοt a fractiοnal number) that can be pοsitive, negative, οr zerο. Examples οf integers are: -5, 1, 5, 8, 97, and 3,043.

c

#include <stdio.h>

int main() {

   int num1, num2, num3;

   int max, min;

   printf("Enter three integers: ");

   scanf("%d %d %d", &num1, &num2, &num3);

   // Assume num1 is the maximum and minimum initially

   max = num1;

   min = num1;

   // Check if num2 is greater than current max

   if (num2 > max) {

       max = num2;

   }

   // Check if num3 is greater than current max

   if (num3 > max) {

       max = num3;

   }

   // Check if num2 is smaller than current min

   if (num2 < min) {

       min = num2;

   }

   // Check if num3 is smaller than current min

   if (num3 < min) {

       min = num3;

   }

   printf("Maximum value: %d\n", max);

   printf("Minimum value: %d\n", min);

   return 0;

}

In this program, we declare variables num1, num2, and num3 to store the input integers. We also declare max and min to keep track of the maximum and minimum values, respectively.

The scanf function is used to take input from the user. The user is prompted to enter three integers, which are stored in num1, num2, and num3.

Next, we compare each input integer with the current maximum and minimum values. If an input is greater than the current maximum, we update the max variable. If an input is smaller than the current minimum, we update the min variable.

Finally, we display the maximum and minimum values on the screen using the printf function.

When you run the program and enter the three integers, it will output the maximum and minimum values among them.

Answer:

(a)     T = 4.09*10^-8 s

(b)     r = 0.19m

Explanation:

(a) In order to determine the rotational period of the protons, you first calculate the angular speed of the proton. You use the following formula for the radius of the trajectory described by the electron in a region with a constant magnetic field:

\(r=\frac{mv}{qB}\)               (1)

m: mass of the proton = 1.67*10^-27 kg

q: charge of the proton = 1.6*10⁻19C

B: magnitude of the magnetic field = 1.6T

v: speed of the proton = 0.1c = 0.1(3*10^8m/s) = 3*10^7m/s

The angular speed of the proton is v/r, then, you solve for w in the equation (1) and replace the values of the parameters:

\(\omega=\frac{v}{r}=\frac{qB}{m}\\\\\omega=\frac{(1.6*10^{-19}C)(1.6T)}{1.67*10^{-27}kg}=1.53*10^8\frac{rad}{s}\)

The rotational period T is:

\(T=\frac{2\pi}{1.53*10^8rad/s}=4.09*10^{-8}s\)

(b) The radius of the protons' orbit is calculated by using the equation (1):

\(r=\frac{(1.67*10^{-27}kg)(3*10^7m/s)}{(1.6*10^{-19}C)(1.6T)}\\\\r=0.19m\)

The radius of the protons' orbit is 0.19m

When light travels from one medium to another, its speed, direction, and wavelength can change, while its frequency remains constant. These changes are due to differences in the refractive indices of the two media.

As light travels from one medium to another, several of its properties change, including its speed, direction, and wavelength. The speed of light changes because the refractive index of each medium is different, which alters the velocity of the wave. The direction of the light may also change, a phenomenon known as refraction, as it enters a medium with a different refractive index. The amount of refraction depends on the angle of incidence, the angle between the incoming light and the normal line to the surface of the medium. Finally, the wavelength of the light may also change due to the refractive index of the medium, a phenomenon known as dispersion. This results in the separation of white light into its component colors when it passes through a prism or other refracting medium.

the maximum range of the 0.850 kg ball is reduced by approximately 10.8% due to the 0.900 N wind force.we need to find the percentage by which the maximum range of the 0.850 kg ball is reduced due to the 0.900 N wind force.

Step 1: Calculate the force due to gravity acting on the ball
Force = mass × acceleration due to gravity
F_gravity = 0.850 kg × 9.81 m/s²
F_gravity = 8.3385 N
Step 2: Calculate the net force acting on the ball
Net force = F_gravity - F_wind
Net force = 8.3385 N - 0.900 N
Net force = 7.4385 N
Step 3: Calculate the percentage reduction in force
Percentage reduction = [(F_gravity - Net force) / F_gravity] × 100
Percentage reduction = [(8.3385 N - 7.4385 N) / 8.3385 N] × 100
Percentage reduction ≈ (0.9 N / 8.3385 N) × 100
Percentage reduction ≈ 10.8%
So, the maximum range of the 0.850 kg ball is reduced by approximately 10.8% due to the 0.900 N wind force.

A block of wood weighing 5 N in air, is difficult fully submerge in a pool of mercury because the buoyant force when fully submerged is (A) more than 5 N.

When an object is submerged in a fluid, it experiences a buoyant force that opposes the force of gravity acting on the object. The magnitude of the buoyant force is equal to the weight of the fluid displaced by the object.

In this case, when the block of wood is fully submerged in a pool of mercury, the buoyant force acting on it will be equal to the weight of the mercury displaced by the block. Since the density of mercury is greater than the density of wood, the volume of mercury displaced will be greater than the volume of the block. Therefore, the buoyant force will be greater than the weight of the block (5 N).

Hence, the buoyant force when fully submerged will be more than 5 N, making it difficult for the block of wood to fully submerge in the pool of mercury.

Answer:

29.436 J/g.°C

Explanation:

We are given;

Mass of tungsten; m_t = 215 g

Initial temperature of tungsten; T_ti = 100°C

Final temperature; T_f = 21.5°C

Mass of water; m_w = 450 g

Initial temperature of water; T_tw = 20°C

From tables, specific heat capacity of water; c_w = 4.184 J/g.C

Thus;

Energy lost by tungsten = energy gained by water

Thus;

215 × c_t × (100 - 21.5) = 450 × 4 184 × (21.5 - 20)

Where c_t is specific heat capacity of tungsten

16877.5c_t = 496800

c_t = 496800/16877.5

c_t = 29.436 J/g.C

When driving down the road and hitting the brakes suddenly, your body moves towards the front of the car due to inertia (Ch.5). Inertia is an object's resistance to change in motion. When the car stops abruptly, your body continues to move forward at the initial speed until an external force, such as the seatbelt, acts upon it, bringing your body to a stop.

When you hit the brakes suddenly while driving down the road, the kinetic energy of the car is quickly converted into thermal energy due to friction between the brake pads and the rotors. This rapid decrease in speed causes your body to continue moving forward due to inertia, which is the tendency of objects to maintain their current state of motion. Therefore, your body moves towards the front of the car until the seatbelt or other restraints stop you from continuing to move forward. This is why it is essential to always wear a seatbelt while driving, as it helps to keep you safe and prevent injury in the event of sudden stops or collisions.

To determine the number of moles of solute in a solution, we need to use the formula:

moles of solute = molarity × volume

In this case, we are given that the solution has a molarity of 0.70 M and a volume of 1.5 L.

Using the given values, we can calculate the moles of solute as follows:

moles of solute = 0.70 M × 1.5 L

moles of solute = 1.05 moles

Therefore, there are 1.05 moles of solute present in 1.5 L of the 0.70 M unknown solution.

Molarity (M) represents the amount of solute (in moles) dissolved in a given volume of solution (in liters). By multiplying the molarity by the volume, we obtain the number of moles of solute.

This calculation is based on the assumption that the volume provided is the total volume of the solution and that the solute is completely dissolved. It's important to note that the molarity can also be expressed as mol/L, indicating moles of solute per liter of solution.

Understanding the number of moles of solute in a solution is crucial for various applications, such as determining reaction stoichiometry, calculating concentrations, and understanding the properties and behavior of the solution.

Power (P) is defined as the rate at which work is done. The formula to calculate power is:

P = W / t

P is the power,

W is the work done,

t is the time taken.

The work done (W) can be calculated as the product of force (F) and distance (d):

W = F * d

In this case, the force is the weight of Kisses, which can be calculated using the formula:

F = m * g

m is the mass of Kisses,

g is the acceleration due to gravity (approximately 9.8 m/s^2).

m = 57 kg

d = 28 m

t = 32 seconds

g = 9.8 m/s^2

First, calculate the work done:

W = F * d

W = (m * g) * d

Next, calculate the power:

P = W / t

Substituting the given values:

W = (57 kg * 9.8 m/s^2) * 28 m

W ≈ 15684.24 J

P = 15684.24 J / 32 s
