Explanation:

The image is either virtual or real and the height of the image is 10cm.

To find the image type and its height, we need to know about the magnification of convex lens.

          Height of image/height of object or image distance(V) / object distance(U)

So, image height = magnification × object height

                            = 2×5 = 10 cm

Thus, we can conclude that the image is virtual if it's formed on the left of the lens and is real if it's formed on the right of the lens. The height of the image is 10 cm.

The total kinetic energy gained by the object when accelerating a 20-n object from rest across a horizontal frictionless table is 10.0 J.

To determine the total kinetic energy gained by the object, we can use the work-energy principle, which states that the work done on an object is equal to the change in kinetic energy of the object.

Work done = change in kinetic energy

W = Kf - Ki

where

W = work done (10.0 J)

Kf = final kinetic energy

Ki = initial kinetic energy (0 J, since the object is at rest)

Given the information provided, we know that a total of 10.0 J of work is done in accelerating the 20-n object from rest.

So,

Kf = W + Ki

Kf = 10.0 J + 0 J

Kf = 10.0 J

Therefore, the total kinetic energy gained by the object is 10.0 J

Answer:

150 km/hr²

Explanation:

The data for the motion of the train includes;

The train starts from rest, therefore, the initial velocity of the train, u = 0 km/hr

The speed of the train after 0.5 hours, v = 75 km/hr

The change in time during the motion of the train, Δt = 0.5 hours

The acceleration, 'a', is the rate of change of velocity with time;

[tex]a = \dfrac{\Delta v}{\Delta t} = \dfrac{v - u}{\Delta t}[/tex]

Therefore, we have;

a = (75 km/hr - 0 km/hr)/(0.5 hr) = 150 km/hr²

a = 150 km/hr² = 150 km/hr² × 1,000 m/km × hr²/(3,600 s)² = 5/432 m/s²

The acceleration of the train, a = 150 km/hr² = 5/432 m/s².

The rate at which an object's position changes when observed from a specific point of view and when measured against a specific unit of time is known as its velocity.

Velocity is the direction at which an object is moving and serves as a measure of the rate at which its position is changing as seen from a specific point of view and as measured by a specific unit of time (for example, 60 km/h northbound).

By dividing the amount of time it took the object to go a certain distance by the overall distance, one can calculate the object's initial velocity. V is the velocity, d is the distance, and t is the time in the equation V = d/t.

An object's velocity can alter depending on whether it moves faster or slower or in a different direction. An object can move faster, slower, or remain stationary by being pushed or pulled in one direction or the other. Or to put it another way, a thing moves because of a force. Gravity and friction both act as sorts of forces that affect how an object moves.

Therefore, the correct answers are:

a) 75 m/s

The method used when an entire mole is removed for examination under a microscope is called an excisional biopsy.

This method involves the surgical removal of the entire mole and some surrounding skin which is then examined under a microscope to check for any abnormal cells or signs of cancer. This method is typically used when a mole is suspected to be malignant or when it cannot be clearly diagnosed as benign through other methods such as a shave or punch biopsy.

The key benefit is that, as opposed to an incisional biopsy, when a bit of the tissue is taken to provide a diagnosis but it will likely still need to be treated later, the aberrant tissue may be identified, diagnosed, and removed in one operation.

The amount of torque produced if the angle between the force and the lever arm is zero is zero.

The formula for torque is:

Torque (τ) = Force (F) x Lever arm (r) x sin(θ)

This is because torque is defined as the product of force and the perpendicular distance from the line of action of the force to the axis of rotation. When the angle between the force and the lever arm is zero, the force is acting parallel to the lever arm, meaning that there is no perpendicular distance between the force and the axis of rotation, resulting in a torque of zero. In other words, the torque is zero when the force is applied in the same direction as the lever arm.

Answer:

Static electricity, specifically electrostatic attraction has occurred.

Explanation:

This phenomenon is known as static electricity, which involves the buildup of electric charges on the surface of a material. It can occur when two materials come into contact and then separate, transferring electrons from one material to the other. When you rub the comb against the rabbit fur, you transfer some of the electrons from the fur to the comb, leaving the fur with a positive charge and the comb with a negative charge. This charge separation creates an electric field around the comb and the fur. When you bring the comb and fur near the paper confetti, the negatively charged electrons in the confetti are attracted to the positive charge on the fur and the confetti sticks to the fur. This process is known as electrostatic attraction.

The ring accelerates in the direction of the net unbalanced force. Thus option C is the correct answer.

According to Newton's second law of motion, the net force acting on an object is equal to the mass of the object multiplied by its acceleration. If the forces exerted by the two students in the tug-of-war are unbalanced, there will be a net force acting on the steel ring.

The direction of this net force will be in the direction of the stronger force. As a result, the ring will accelerate in the direction of the net unbalanced force. This means that the ring will begin to move, and its velocity will change as long as the net force is applied.

Since the steel ring is accelerating, it can no longer be at rest, and it will not move at a constant velocity. The ring will move in the direction of the stronger force until the forces exerted by the students are balanced again.

Answer:

An unbalanced force is a force that causes an object's state of motion to change. In other words, unbalanced forces are the things that make objects speed up or slow down.

Explanation:

(self-explanatory)

Unbalanced forces are the forces which are not balanced. The two or more forces which are not equal in magnitude are called as unbalanced forces. If the forces acting on an object are balanced the the total force is zero as these forces cut each other out. Only when the forces are unbalanced, it causes a change in the the speed of the object, its shape, or the direction of its motion.

More large items will attract each other as the gravitational force between them grows because gravitational force is directly proportional to the mass of both interacting objects.

An object's inertia increases with mass, hence it requires more force to alter its state of motion. The mass of an item, which is roughly equal to the quantity of material inside it, determines how much inertia it has.

Theoretically, anything with mass generates small particles known as gravitons, which is why mass and gravity are related. The gravitational attraction is caused by these gravitons. Gravitons increase with mass.

Answer:

This is a very straightforward problem, and not too difficult to do in your head. If we have two nearly equal resistances, the series resistance (Rs) is twice the average value (midpoint between the two) and the parallel resistance Rp) is approximately equal to half the midpoint value. So a rough initial guess might be 12 and 13 ohms, where Rs is 25 ohms but Rp is approximately 6.25 ohms. Since Rp needs to be lower, we can play around with resistor values. Here’s an easy shortcut:

Let’s start with the equation for two parallel resistors:

Rp = (R1 * R2)/(R1 + R2)

Since Rs = R1 + R2,

Rp = (R1 * R2)/Rs.

We can rewrite this as

Rp * Rs = R1 * R2

Plugging in our numbers (Rp = 6, Rs = 25), we see that R1 + R2 = 150. What two numbers in the vicinity of 12 and 13 have the product of 150 and a sum of 25? Immediately 10 and 15 come to mind! Easy enough!
