I Explain why you feel cold when tap or well water in winter. state with reason.<br><br>​
attashe74 [19]

Answer:

We feel cold when tap or well water in winter because heat flows from hot body to cold body.

Explanation:

Our <em>body</em><em> </em><em>is</em><em> </em><em>in</em><em> </em><em>optimal</em><em> </em><em>status</em><em> </em><em>is</em><em> </em><em>a</em><em> </em><em>hot</em><em> </em><em>body</em><em> </em><em>and</em><em> </em><em>tap</em><em> </em><em>or</em><em> </em><em>we</em><em>ll</em><em> </em><em>water</em><em> </em><em>is</em><em> </em><em>a</em><em> </em><em>cold</em><em> </em><em>body</em><em>.</em><em> </em><em>Theref</em><em>ore</em><em> </em><em>we</em><em> </em><em>feel</em><em> </em><em>cold</em><em>.</em>

Which equation represents the total energy of a system?
aev [14]

C) Total Energy = Potential Energy + Kinetic Energy

Explanation:

The total energy of a system (also called mechanical energy) is given by:

E=PE+KE

where

PE is the potential energy

KE is the kinetic energy

The two types of energy have a different origin:

  • Potential energy (PE) is the energy possessed by an object due to its position. It is commonly in the form of gravitational potential energy, which is the energy due to the position of the object in the gravitational field, defined as:

PE=mgh

where m is the mass of the system, g the acceleration of gravity, h the heigth of the object relative to the ground

  • Kinetic energy (KE), which is the energy possessed by an object due to its motion. It is calculated as

K=\frac{1}{2}mv^2

where m is the mass of the system and v is its speed.

Object A is negatively Charged. object A and Object B attract. Object B and Object C repel. Object C and Object D attract. What
3241004551 [841]

Remember opposites attract and same charges repel each other.

Object A= negatively charged.

Object A and B attract so B must be positively charged.

Object B and C repel so because B is positively charged C must also be positively charged.

Object C and D attract and because C is positively charged, D must be negatively charged.

A 920 kg cannon fires a 3.5 kg shell at initial acceleration of 95 m/s^2. What is the cannon's recoil force?
Mice21 [21]

Answer:

The cannon recoils with a force of 332.5 N

Explanation:

By Newton's third law Recoil force on cannon = Force in shell.

Force in shell = Mass of shell x Acceleration of shell

Mass of shell = 3.5 kg

Acceleration of shell = 95 m/s²

Force in shell = 3.5 x 95 = 332.5 N

Recoil force on cannon = 332.5 N

So, the cannon recoils with a force of 332.5 N
