Temperature rise will be there in cylinder B more than in cylinder A because of internal energy.

what is internal energy?

The sum of the kinetic and chemical potential energies of all the particles in the system is the internal energy. Particles accelerate and pick up kinetic energy when energy is applied to increase the temperature.

Briefing:

Cylinder A uses the heat it absorbs to both work while expanding and to increase internal energy (or temperature).

While cylinder B solely uses the heat it absorbs to increase its internal energy 

As a result, cylinder B's temperature rise is greater than cylinder A's.

antoniya [11.8K]

Answer:

The package will be directly below the location of the plane.

Explanation:

Look up projectile motion for more information. The horizontal speed of the package is separate from the vertical speed of the package. The vertical speed of the falling package will be based on the rate of acceleration and the height of the package when dropped. The horizontal speed of the package will be the same as the plane so the package will remain directly below the plane the entire time until the package hits the ground.

Suppose that you have a rod that is positively charged, a rod that is negatively charged and a stand that allows rotation. If yo
amm1812

Answer:

Explanation:

A charge is produced when an atom losses or gains an electron. The law of static electricity states that like charges repels, while unlike charges attracts.

1. To determine the charge on the polystyrene rod.

Place the polystyrene rod on the non-conducting rotating stand, and bring the positively charged rod close to it. If attraction occurs, it shows that it is oppositely charged. If repulsion occurs, it shows that it is positively charged.

Bringing a negatively charged rod close to the rotating polystyrene rod would attract it if the charge is opposite. But if the charge on the two rods are the same, repulsion occurs.

2a. When the polystyrene rod is positively charged, it would attract the negatively charged rod but repel the positively charged rod.

b. When the polystyrene rod is negatively charged, it would repel the negatively charged rod but attract the positively charged rod.

c. When the polystyrene rod is uncharged, no reaction would be observed when either the positively charged or negatively charged rod is brought close to it.

Kryger [21]

Answer:

1. Velocity = 75.39 m/s

2. Air resistance

3. Mass of the coin

Explanation:

1. Given that the height of the building is 290 m. From Newton's third law of motion,

V^{2} = U^{2} + 2gh

where: V is the final velocity of the coin, U is the initial velocity, g is the force of gravity and h is the height.

Since the coin was dropped from a height, its initial velocity is zero. The force of gravity is taken as 9.8 m/s^{2}, so that:

V^{2} = 0 + 2 x 9.8 x 290

   = 5684

V   = \sqrt{5684}

    = 75.3923

The velocity with which the coin hits the ground is 75.39 m/s.

2. Air resistance: During the free fall of the coin, the direction of wind flow could either cause an increase or decrease the value predicted.

ii. Mass of the coin: This can also affect the predicted value.
