Answer:

option C

Explanation:                          

The correct answer is option C.

A meter stick is not uniform                        

when you balances,                                          

At 45 cm position it is in equilibrium.                                          

The equilibrium shift to the heavy region, if you increase load on side then equilibrium will shift from the center to toward the heavy load.

To be a body to be in equilibrium weight on both the side of the stick should be equal.                                                      

hence, mass on both side is equal.

When you apply the torque equation ∑τ = 0 to an object in equilibrium, the axis about which torques are calculated:
kupik [55]

Answer:

option D.

Explanation:

The correct answer is option D.

When an object is in equilibrium torque calculated at any point will be equal to zero.

An object is said to be in equilibrium net moment acting on the body should be equal to zero.

If the net moment on the object is not equal to zero then the object will rotate it will not be stable.

A box is being pulled by two ropes. Eduardo pulls to the left with a force of 500 N, and Clara pulls to the right with a force o
sergejj [24]

Answer:

kinetic friction or something else

Explanation:

Draw a diagram to illustrate the problem, as shown below.

m = mass of the box, kg

mg =  weight of the box, N, acting downward

Because of Newton's 3rd law, a normal force of N = mg acts upward on the box.

C = 200 N, the force applied by Clara, horizontally to the right

E = 500 N, the force applied by Eduardo, horizontally to the left.

Because E is greater than C, the box will move left.

The frictional force, F, will resist the initial motion. Its magnitude is

F = μN = μmg, where μ = kinetic coefficient of friction.

F acts horizontally to the right.

From the given table, we can conclude that

Normal force acting upward is correct

Tension by Eduardoacting left is correct.

Tension by Clara acting right is correct.

Kinetic friction acting left is Incorrect.

Gravity acting downward is correct.correct

Answer:

The direction of the kinetic friction force is incorrect

A What CE describes the way energy is stored in a sandwich​
SVETLANKA909090 [29]
What is Potential Energy? You probably already know that without eating, your body becomes weak from lack of energy. Take a few bites of a turkey sandwich, and moments later, you feel much better. That's because food molecules contain potential energy, or stored energy, that can do work in the future. Hope it helps

The alpha particles leave visible tracks in the cloud chamber because
julia-pushkina [17]
<h2>Answer: Ionization </h2>

The inner atmosphere of a <u>cloud chamber</u> is composed of an easily ionizable gas, this means that little energy is required to extract an electron from an atom. <u>This gas is maintained in the supercooling state, so that a minimum disturbance is enough to condense it</u> in the same way as the water is frozen.

<h2>Then, when a charged particle with enough energy interacts with this gas, it <u>ionizes</u> it. </h2>

This is how alpha particles are able to ionize some atoms of the gas contained inside the chamber when they cross the cloud chamber.

These ionized atoms increase the surface tension of the gas around it allowing it to immediately congregate and condense, making it easily distinguishable inside the chamber like a <u>small cloud</u>. In this way, it is perfectly observable the path the individual particles have traveled, simply by observing the cloud traces left in the condensed gas.
