Why is it unwise to stir a pot of soup with a metal spoon?

Answer:

To prevent the soup from cooling soon and prevent our hands from high temperature of the spoon by the contact of soup.

Explanation:

  • It is unwise to stir a pot of soup with a metal spoon because the metal has a much lower specific heat capacity than that of water i.e. it requires lesser heat energy to raise its temperature.
  • Soup being a blend of edible fats and vegetables forms a layer of fat and starch on the surface preventing much of the heat from escaping to the environment and thus delaying the process of loosing the heat to the ambiance.
  • When a spoon is put into soup it becomes an accessible good conductor path for the heat to escape easily as a result it also increases the temperature of spoon significantly due to its low specific heat capacity.

Answer:

Explanation:

As we stir the pot of soup by a metal spoon which is a conductor, it conducts the heat and starts heating after some time the temperature of the spoon rises and we are not able to hold the spoon and we get burns.

What are the two forces that keep a pendulum swinging?
NemiM [27]
The correct answer would be the third option. The two forces that keep a pendulum swinging would be tension and gravity. The force of gravity causes the pendulum to keep it swinging and tension blocks all resistances in order for the motion to continue.

A disk is free to rotate about an axis perpendicular to the disk through its center. If the disk starts from rest and accelerate
garri49 [273]

Answer:

(C) 16 radians

Explanation:

The angular displacement is given by the following equation:

\Delta \theta=\omega_i t+\frac{1}{2}\alpha t^2

Here

\Delta \theta Is the angular displacement of the body at the indicated time (t).

\omega_i Is the angular velocity of the body at the initial moment.

\alpha Is the angular acceleration of the body.

The disk starts from rest, so \omega_i=0

Replacing the given values:

\Delta \theta=\frac{1}{2}(2\frac{radians}{s^2})(4s)^2\\\Delta \theta=16 radians

Anna pushes a box with a force of 8.00 newtons. She generates a power of 3.00 watts. How much time does it take for Anna to move
QveST [7]
Power is the energy in a system per time.  It will have units of Watts which is equal to joules per second. It can be expressed as:

P = E / t

where E = Force x distance

P = Fd / t
t = Fd / P
t = 8 (9.72) / 3.0
t = 25.92 s

givi [52]
The weight on Earth would be:
77.3 * 9.8
= 757.54 Newtons
1 Newton = 0.2248 lbf
757.54 * 0.2248
= 170.29 lbf

On the asteroid:
77.3 * 0.08
= 6.18 Newtons
Applying the same conversion:
77.3 * 0.2240
= 17.31 lbf
