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 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:

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.

In this spring-mass system, the total energy equals the elastic potential energy at the moment the mass is temporarily at rest at x = A = 6 cm (i.e., at the extreme ends of the simple harmonic motion).

Here initial speed u=0m/s    final speed v=26.5 m/s and acceleration due to gravity g=9.81 m/s^2

Where:

m = mass of the object (kg)

g = acceleration due to gravity (9.8 m/s^2)

h = height of the cliff (m)

We know the velocity of the object just before it hits the ground, which is 26.5 m/s. We can use this velocity to calculate the kinetic energy of the object just before it hits the ground.

KE = (1/2)mv^2

As the object is dropped from the cliff, its initial potential energy is converted to kinetic energy. Therefore, the initial potential energy is equal to the final kinetic energy.

GPE = KE

mgh = (1/2)mv^2

We can solve for h by rearranging the equation and substituting the known values for GPE, KE, m, and g.

Simply multiply the acceleration of gravity by the period of time since the object was released to determine the object's speed (or velocity). In other words, velocity is equal to -9.81 m/s2 * time, or V = gt. The item is just traveling downwards when there is a negative sign.

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.

In 1957, Sputnik I was propelled into orbit around the planet. Its speed when it was at its perigee was was approximately 7.935 x 10^3 m/s.

The speed of an object in orbit around Earth can be calculated using the vis-viva equation:

v = sqrt(GM/(r))

where v is the velocity of the object, G is the gravitational constant, M is the mass of the Earth, and r is the distance of the object from the center of the Earth.

Given the perigee distance of 6.41 x 10^6 m and the mass of the Earth being 5.972 x 10^24 kg, the velocity of Sputnik I at its perigee would be:

v = sqrt((6.67 x 10^-11 N*(m^2)/(kg^2) * (5.972 x 10^24 kg)) / (6.41 x 10^6 m))

v = 7.935 x 10^3 m/s

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:

Explanation: Get dem hearts up:)

the whole distance is five. The main point is that you must be aware of if and when the particle reverses course.

In order to determine the velocity, differentiate the displacement and set it to zero.

It is obvious that at t=1, the velocity is zero.

S=3 is the starting location at time t=0. At t=1,s=2 \s.

The total distance traveled is 1.

The additional distance traveled is 62=4 at time t=3 and s=6.

Thus, the whole distance is five.

L=30|s′(t)|dt=30|2t2|dt=1022tdt+312t2dt=5 is the length of the image of s|[0,3] and represents the total distance traveled between t=0 and t=3. .

When calculating the traveled distance of a particle satisfying the law of motion s(t) between t=a and t=b, another method that can be used if you are unfamiliar with the arc length formula is to first determine the critical points in (a,b), such as t1tk, and then multiply those values by the following formula: |s(t1)s(a)|+|s(t2)s(t0)|++|s(b) Since there is just one critical moment in your particular scenario, t=1, L=|s(1)s(0)|+|s(3)s(1)|=1+4.

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!

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.
