Answer:

t = 3.01 s

Explanation:

In order to calculate how long it takes to the object to fall to the ground, you use the following formula, for the calculation of the height:

\(y=y_o-v_ot-\frac{1}{2}gt^2\)    (1)

yo: height of the building = 105 m

vo: initial velocity of the body = 20m/s

g: gravitational acceleration = 9.8m/s^2

t: time = ?

To find the time t, you take into account that when the body arrives to the ground the height is zero, that is, y = 0.

You replace the values of all parameters in the equation (1), and you obtain a quadratic polynomial for t:

\(0=105-20t-\frac{1}{2}(9.8)t^2\\\\0=-4.9t^2-20t+105\)

Next, you use the quadratic formula to get the roots of the polynomial:

\(t_{1,2}=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\)

a = -4.9

b = -20

c = 105

\(t_{1,2}=\frac{-(-20)\pm\sqrt{(-20)^2-4(-4.9)(105)}}{2(-4.9)}\\\\t_1=3.01s\\\\t_2=-7.09s\)

You choose the positive value t1, because it has physical meanning.

Hence, the body takes 3.01s to arrive to the ground

because mechanical advantage decreases due to the friction and weight of moving parts of the machine whereas the velocity ratio remains constant

The image is located 63.8 mm to the right of the lens. The negative sign indicates that the image is inverted. The absolute value of the height of the image is 0.0445 m or 4.45 cm.

1/f = 1/do + 1/di

where f is the focal length of the lens, do is the object distance, and di is the image distance.

(a) do = 36.2 mm = 0.0362 m

Then, we can plug in the values and solve for di:

1/0.032 = 1/0.0362 + 1/di

di = 0.0638 m = 63.8 mm to the right of the lens

Focal length is a fundamental concept in optics and photography that refers to the distance between the optical center of a lens and the image sensor or film when the lens is focused on an object at infinity. It is measured in millimeters and determines the angle of view and magnification of the lens.

A shorter focal length produces a wider angle of view, allowing more of the scene to be captured in the frame, while a longer focal length produces a narrower angle of view, magnifying the subject and isolating it from its surroundings. Focal length also affects depth of field, which is the range of distances in an image that appear sharp.

The modulus of elasticity, E, is a measure of a material's stiffness and ability to resist deformation when a force is applied. It is defined as the ratio of stress to strain within the elastic range of the material. In other words, it describes how much a material will stretch or compress under a given force.

The modulus of elasticity is important because it allows engineers to predict how materials will behave under different conditions, such as temperature changes, loading conditions, and other factors. It also helps to determine the maximum load a material can withstand before it starts to deform or break.

In detail, the modulus of elasticity is a fundamental property of a material that describes its ability to resist deformation when subjected to external forces. It is calculated by measuring the stress and strain of the material and using the equation E = σ/ε, where σ is stress and ε is strain.

The modulus of elasticity is important in many areas of engineering, such as structural design, materials science, and mechanics. It helps to ensure that structures and materials are designed and tested to withstand the loads and stresses they will be subjected to, and it provides a basis for comparing different materials and choosing the best one for a particular application.

In summary, the modulus of elasticity, E, is a material property that describes its stiffness and resistance to deformation. It is correctly determined using Hooke's Law and is crucial for predicting the mechanical behavior of materials when subjected to stress.

Given: Distance (x) covered by the ball = 180 m, maximum height (y) reached by the ball = 21.3 m The trajectory followed by the ball can be modelled using the equations of motion. The initial velocity of the ball is 31.63 m/s.

The equations of motion relate the displacement, velocity, time and acceleration of the moving body. The general equation of motion for vertical motion under gravity is: y = u sinθt - 1/2 gt²where y is the vertical displacement, u is the initial velocity, θ is the angle of projection, g is the acceleration due to gravity and t is the time taken to reach the maximum height.

The maximum height is given by: (u y = 0)t = u sinθ/g Solving for t, we have: t = (u sinθ)/g Therefore, the equation of motion becomes: y = (u²sin²θ)/ 2 g Putting the given values in the above equation:21.3 = (u² sin² 45)/ (2 x 9.8) => u = 31.63 m/s Therefore, the initial velocity of the ball is 31.63 m/s.

This motion of the balloon is an example of buoyancy, which is the upward force exerted by a fluid on an object immersed in it.

When the balloon is neutrally buoyant, it means that the weight of the balloon and the weights attached to it is equal to the weight of the water displaced by the balloon.

If you push the balloon down to a greater depth and then release it, the balloon will rise back up to its original position.

This is because the balloon is still partially inflated and contains air, which is less dense than water. When you push the balloon down, the water pressure compresses the air in the balloon, causing it to become smaller in size.

When you release the balloon, the compressed air expands and pushes the balloon upwards towards the surface of the water.

Answer: 20 it

Explanation:

The net force is the vector sum of all forces exerted on an object. The net force, or, to put it another way, the sum of all the forces, is the outcome of the fact that a force is a vector and that two forces of equal size and opposite direction cancel each other out.

The net force always mirrors the acceleration's direction. The net force acting on an object traveling in a circle at a constant speed is pointed in the direction of the circle's center. Such a direction is referred to as centripetal.

The formula below demonstrates how the mass of an item multiplied by its acceleration determines the size of the net force acting on it. An object is not speeding and is in a state known as equilibrium if the net force acting on it is zero.

The total force acting on an object is referred to as the net force. Mass can be accelerated by a net force. A body, whether it is at rest or in motion, is subject to another force. The term "net force" is used to describe a system that is under the influence of numerous forces.

The Perpendicularity would be the connection of two lines that meet in such a right angle perpendicularity (90 degrees). It extends to all geometric objects involved.

The Distance was its cumulative motion of a body regardless of the direction that's why the value "d" is perpendicular to the distance from the transformer.

The equilibrium constant K can be changed for a chemical reaction at equilibrium by changing the temperature and the total concentration of reactants and products.

The correct option is d. I and II only.

.A chemical reaction at equilibrium is the point at which the rates of the forward and reverse reactions are equal. At equilibrium, the concentrations of the reactants and products remain constant. The equilibrium constant, K, is a value that describes the relative amounts of products and reactants at equilibrium.

The value of K is a function of temperature only, so changing the temperature of the system will change the value of K. The equilibrium constant K also depends on the concentration of reactants and products. Therefore, changing the total concentration of reactants and products will change the value of K.

The equilibrium constant K also depends on the reaction coefficients, but changing the coefficients does not change the value of K. This is because the equilibrium concentrations of the reactants and products will adjust to compensate for the change in coefficients

The angle between the two forces is 91 degrees

In order to find the angle between two forces, we have to use the following formula: cos θ= (F₁.F₂)/(|F₁||F₂|)

Where F1 and F2 are the magnitudes of the two given forces, θ is the angle between the two forces and F1.F2 is the dot product of the two forces.

We have given two forces of 574 N and 577 N and the resultant force of 1142 N.

We can solve for the angle between the two forces as follows;

Resultant force = √(574² + 577² + 2×574×577×cos θ)1142

                          = √(574² + 577² + 2×574×577×cos θ)

cos θ = [(1142² - 574² - 577²)/2×574×577]

cos θ = -0.048

We know that cosine is negative in the second quadrant, so we need to find the angle in the second quadrant.cos⁻¹(-0.048) = 91.4°

Thus, the angle between the two forces is 91 degrees (rounded to the nearest integer as needed) which can also be written as π/2 radians.

The forces have been provided to us as 574 N and 577 N, and the resultant force is 1142 N.

We can now use the formula cos θ= (F₁.F₂)/(|F₁||F₂|) to calculate the angle between the two forces.

We know that the magnitude of the resultant force is the sum of the magnitudes of the two given forces.

Using this knowledge, we can find the angle between the two forces by first substituting the given values in the formula, and then solving for the angle.

In this case, cos θ is found to be -0.048. Since the cosine function is negative in the second quadrant, we can find the angle in the second quadrant by taking the inverse cosine of -0.048.

The result of this calculation is 91.4 degrees.

Therefore, π/2 radians or 91 degrees separate the two opposing forces. (rounded to the nearest integer as needed)

An object with a mass of 4kg, lying on a rough table, experiences a frictional force of 15N and a horizontal force of 25N, resulting in a net force of 10N, causing the object to accelerate to the right with an acceleration of 2.5 m/s².

Normal force Frictional force (15N)

The normal force points upwards and is equal in magnitude to the weight of the object (mg = 4kg * 9.81m/s² = 39.24N) since the object is not accelerating in the vertical direction.

The frictional force points to the left and is equal in magnitude to the force applied to the object (15N = 25N), indicating that the object is not moving horizontally.

The resultant force is found by subtracting the frictional force from the applied force:

F_net = F_applied - F_friction = 25N - 15N = 10N

The object will accelerate to the right with an acceleration of:

a = F_net/m = 10N/4kg = 2.5 m/s²
