Answer:

The Bohr model suggested that electrons orbited the nucleus in circular paths where as the modern model views the atom to consist of positively charged nucleus surrounded by electrons.

Explanation:

In the modern model, the nucleus contains two sub-atomic particles, the protons which are positively charged and the neutrons which are not charged.According to Bohr's model,the electron in a hydrogen atom travel around the nucleus in a circular orbit. In the modern model, electrons do not move around nucleus around circular obits.

A cylindrical grain has a base radius of 5m. the surface area is 1099m^2. What is the height of the bin to the nearest metre?
Inessa05 [86]

The height of the bin is 29.9m.

The quantity of space enclosing a three-dimensional shape's exterior is its surface area.

The total surface area of the cylinder formula is simply the sum of the base surface area and the lateral surface area.

The radius of the cylinder, r = 5m

Surface area = 1099 m²

∴ A = 2πrh + 2πr²

  h = \frac{A- 2\pi r^2}{2\pi r}

  h = \frac{1099- 2 (3.141) 5^2}{2 (3.141) 5}

  h = \frac{1099- 157.05}{31.41}

  h = \frac{941.95}{31.41}

  h = 29.9 m

Therefore, the height of the bin is 29.9m.

Calorimeter containing 1000 grans of water the initial temperature of water is 24.85 degrees . the heat of water is 4.184 j/g de
kvasek [131]
<h3><u>Answer;</u></h3>

10.80 ° C

<h3><u>Explanation;</u></h3>

From the information given;

Initial temperature of water =  24.85°C

Final temperature of water = 35.65°C

Mass of water = 1000 g

The specific heat of water ,c = 4.184 J/g °C.

The heat capacity of the calorimeter  = 695 J/ °C

Change in temperature ΔT = 35.65°C - 24.85°C

                                             = 10.80°C

Elza [17]

Answer:

D.

Explanation:

Translation:

A. make a barbecue

B. organize a picnic

C. swimming in the pool

D. to go skiing

Barbecue is usually a summer activity, so we eliminate that.

It would be too cold for a picnic!

It would be too cold to go swimming, and that's more of a summer thing!

Skiing is a snow activity, and since it is winter, it is likely to know.
