A manufacturer supplies plastic cups that are placed under the legs of the chair. The manufacturer's claim is that there will be no marks of chair due to pushing or pulling on the floor.

<h3>Who is a manufacturer?</h3>

A manufacturer is a person who converts his idea of developing and constructing any item using some set of machines.

A manufacturer supplies plastic cups that are placed under the legs of the chair.

When there is a relative motion between two objects, friction force causes the opposition to this motion. Between chair and floor, there will be high magnitude of force. But if we insert plastic cups in the legs of chair, then the friction between cup and floor will be less. This keeps the floor protected form any scratches.

Andrew is pushing this block to the right across on the floor. Which force in the free body diagram is pointing in the wrong dir
soldier1979 [14.2K]

Answer:

the normal force

Explanation:

The free-body diagram represents all the forces acting on an object. In this example, there are four forces acting on the box: an applied force, the friction (which always act opposite to the applied force), the weight of the box (which is always downward), and the normal force.

The normal force is the reaction force exerted by the surface on which the box is moving on the box, and this reaction force is always opposite to the force exerted by the box on the surface. Since the latter is downward, it means that the normal force must be upward, so in the diagram it is wrong.

Would tap water likely freeze and boil at those exact temperatures? (temperature freezes at 0 degree celius and boils at 100 deg
Kitty [74]

No

Explanation:

Tap water will not boil and freeze at those exact temperature which are the boiling and freezing points.

O°C and 100°C are the boiling points of pure water.

Pure water is a pure substance with a definite composition made up of 2 atoms of hydrogen and 1 atom of oxygen.

Pure water boils at  100°C  and freezes at O°C ,

  • Tap water is not pure water.
  • It has some impurities in it which causes causes the elevation of the boiling point of liquids and widening of the boiling range.
  • Tap water is treated water that contains some other dissolved chemicals.

An unknown material, m1 = 0.49 kg, at a temperature of T1 = 92 degrees C is added to a Dewer (an insulated container) which cont
erastova [34]

Answer:

c_u=1540.5J/kg^{\circ}K

Explanation:

We know that heat relates to mass, specific heat and variation of temperature experimented because of this heat through the equation Q=mc\Delta T=mc(T_f-T_i). The heat released by the unknown material is absorbed by water, so we have Q_u=-Q_w, and we can write:

m_uc_u(T_{uf}-T_{ui})=-m_wc_w(T_{wf}-T_{wi})

Since thermal equilibrium is reached we know that T_{cf}=T_{wf}=T_f=31^{\circ}C=304^{\circ}K, where we have added 273^{\circ} to convert the temperature from Celsius to Kelvin, as <em>we must do</em>. Since we want the specific heat of the unknown material, we do:

c_u=-\frac{m_wc_w(T_f-T_{wi})}{m_u(T_f-T_{ui})}

Which for our values is:

c_u=-\frac{(1.1kg)(4186J/kg^{\circ}K)((304^{\circ}K)-(294^{\circ}K))}{(0.49kg)((304^{\circ}K)-(365^{\circ}K))}=1540.5J/kg^{\circ}K

Define the term Distance.​
Aloiza [94]

Distance is defined as the space between two points in space.

<h3>What is distance?</h3>

Distance is defined as the space between two points in space.

The unit of distance is metres or kilometres.

Distance can be measured directly usind instruments such as metre rule and tape rule.

The formula for calculating distance is given below:

Distnce = velocity × time.

Therefore, distance is defined as the space between two points in space.
