A force that exists between any two objects that have mass

The value of theta for the maximum height is 30°.

Calculation:-

Since the angle from the horizontal is Cosθ, therefore the angle from the vertical is sinθ.

Hmax = U² sin²θ/2g

11.25 = 30² sin²θ/2g

sin²θ = (11.25 × 2 × 10)/900

   ⇒    sin²θ   =   0.25

    ⇒   sin θ = 0.5

    ⇒   sin θ = 1/2 = 30°

The horizontal pace of a projectile is regular (in no way converting in value), and there's a vertical acceleration because of gravity; its cost is 9.8 m/s/s, down, The vertical speed of a projectile changes via nine.8 m/s every second, The horizontal motion of a projectile is impartial of its vertical movement.

Projectile motion is a form of motion experienced with the aid of an object or particle that is projected in a gravitational field, such as from Earth's floor, and movements alongside a curved route below the action of gravity best.

Projectile motion is the movement of an object thrown (projected) into the air. After the initial force that launches the item, it most effectively reports the pressure of gravity. The object is known as a projectile, and its route is called its trajectory.

The equation for energy given by the friend, energy = distance × force, is incorrect.

The equation presented by the friend, energy = distance × force, is not consistent with the principles of dimensional analysis. Dimensional analysis involves examining the units of the quantities involved in an equation to ensure they are consistent on both sides of the equation. In this case, the units on the right side of the equation do not match the units of energy.

In the equation, distance is given as a unit of length, typically measured in meters (m). Force is given as a unit of mass multiplied by acceleration, typically measured in kilograms (kg) times meters per second squared (m/s²). Multiplying distance by force would yield units of meters multiplied by kilograms multiplied by meters per second squared, which is not equivalent to the units of energy.

The correct equation for energy should involve the dot product or scalar product of the distance and force vectors. The dot product takes into account both the magnitude of the force and the displacement vector of the distance. It would result in a scalar quantity, which is the correct representation of energy. Therefore, the friend's equation lacks the dot product operator, and that's why we know it is incorrect without even looking at the specifics of the problem.

Answer:

Current, I = 8 Amps

Explanation:

Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.

Mathematically, Ohm's law is given by the formula;

\( V = IR\)

Where;

V represents voltage measured in voltage.

I represents current measured in amperes.

R represents resistance measured in ohms.

Given the following data;

Resistance, R = 30 ohms

Voltage, V = 240V

To find the current;

\( I = \frac {V}{R} \)

\( I = \frac {240}{30} \)

Current, I = 8 Amps

Therefore, the current of the dryer is 8 Amperes.

A location's net ocean current motion is 90 degrees to the right of the location's predominant wind direction.

This is brought on by the Coriolis force, which causes moving objects in the Northern Hemisphere to be deflected to the right and in the Southern Hemisphere to the left. The Earth's rotation produces the Coriolis force, which deflects the direction of moving things like ocean currents. In the Northern Hemisphere, the deflection is to the right, while in the Southern Hemisphere, it is to the left. Because the wind propels the surface currents, which are subsequently deflected by the Coriolis force, the direction of net ocean current motion at a site is 90 degrees to the right of the direction of the prevailing wind. Large-scale ocean circulation patterns, including the Antarctic Circumpolar Current in the Southern Ocean and the Gulf Stream in the North Atlantic, are created as a result.

Explanation:

So, the net force will be felt on particle \(\sf{q_1}\) approximately 15.39 N to the right.

Hi! Here I will explain the net force of three charges that interacts. Remember that this question can be solved using Coulomb's Law. Coulomb's Law states that the interaction force between two interacted charges will be proportional to the magnitude of the charges that have specific interaction but inversely proportional to the square of the value of the distance between each other. So, with this concept, we can calculate the magnitude of coulomb force with this equation:

\( \boxed{\sf{\bold{F = k \cdot \frac{q_1 \cdot q_2}{(r_{12})^2}}}} \)

On this condition, the net force will be felt only by the first charge, so we must define the position of the first charge as a fixed one. So, we can calculate the magnitude of coulomb force concerning the first charge with this equation:

\( \boxed{\sf{\bold{\sum F_{q1} = k \cdot (\frac{q_1 \cdot q_2}{(r_{12})^2} + \frac{q_1 \cdot q_3}{(r_{13})^2})}}} \)

With the following condition:

A particular automobile with an initial speed of 65 km/h will come to 120 km/h in 8.49 s

The formula for Uniformly varied rectilinear motion (UVRM) and procedure we will use to solve this exercise is:

t = (vf - vi) /a

Where:

Information about the problem:

By converting the velocity from km/h to m/s, we get:

65 km/h * (1000 m / 1 km) * (1 h / 3600 s) = 18.056 m/s

120 km/h * (1000 m / 1 km) * (1 h / 3600 s) = 33.33 m/s

Applying the time formula, we have:

t = (vf - vi) /a

t = (33.33 m/s - 18.056 m/s) / 1.8 m/s2

t = 15.274 m/s /  1.8 m/s2

t =  8.49 s

The minimum angle at which the box would begin to move is given by the equation $\mu_{s} = \tan{\theta}$,is 21.8°.

Let's consider the following diagram: In the above, m is the mass of the box, θ is the angle of the incline, N is the normal force, f is the force of friction, and mg is the gravitational force acting on the box in the downward direction.

The box will be at the threshold of sliding up or down the plane when the gravitational force acting down the plane is greater than the frictional force acting up the plane. Therefore, the minimum angle at which the box will start to move is:tanθ = μswhere μs is the coefficient of static friction=0.4 (Given). Thus,θ= tan-1 (0.4)θ = 21.8 degrees.

The speed at which a particle's relativistic momentum equal twice its classical momentum, will be 2.598* 10^8 m/s.

Relativistic momentum ensures that the conservation of momentum holds in all inertial frames.

The relativistic effects of length contraction, time dilation, and other similar phenomena are experienced by particles when they move at very high speeds (near the speed of light). The mass of the particles also varies at this high speed. The relativistic momentum is the product of the particle's velocity and its corresponding relativistic mass.

Explanation:

A. The area of the object can be calculated by breaking it down into smaller shapes and adding their areas together. We can see that the object consists of a rectangle and a semicircle :

Therefore, the total area of the object is 12 + 3.53 = 15.53 square inches. Answer:

B. To find the X coordinate of the center of mass, we need to find the centroid of the object. The centroid is the point where the object would balance if it were placed on a pin. The X coordinate of the centroid can be found using the formula:

Where A is the area of each shape and x is the distance from the centroid of each shape to the Y axis.

The centroid of a rectangle is at the center, which is at (3,1). The centroid of a semicircle is at (4/3, 4/3) from the center of the circle.  Therefore, the X coordinate of the centroid of the semicircle is at 3 + (4/3) = 4.33. We can now use the formula to find the X coordinate of the centroid of the object: Xc = (A1x1 + A2x2) / (A1 + A2) = ((6 x 2 x 3) + (1/2 x π x 1.5^2 x 4.33)) / (12 + 3.53) = 2.9 inches.

The Answer:

C. To find the Y coordinate of the center of mass, we can use a similar formula:

The Y coordinate of the centroid of the rectangle is at 0.5, and the Y coordinate of the centroid of the semicircle is at 2/3 from the center of the circle. Therefore, the Y coordinate of the centroid of the semicircle is at 1 + (2/3) = 1.67. We can now use the formula to find the Y coordinate of the centroid of the object: Yc = (A1y1 + A2y2) / (A1 + A2) = ((6 x 2 x 0.5) + (1/2 x π x 1.5^2 x 1.67)) / (12 + 3.53) = 1.07 inches.
