Answer:In 2H_2SO_4, the number of hydrogen atoms is 4 ,the number of sulfur atoms is 2 and the number of oxygen atoms is 8.

Explanation:

Molecular formula of sulfuric acid is H_2SO_4

the 2 in front of H_2SO_4 menas that there are two molecules of H_2SO_4.

In 2 molecules of H_2SO_4 there are:

  • 4 atoms of hydrogen.
  • 2 atoms pf sulfur
  • 8 atoms of oxygen.

g A spherical container of inner diameter 0.9 meters contains nuclear waste that generates heat at the rate of 872 W/m3. Estimat
zhannawk [14.2K]

Answer: The total rate of heat transfer from the container to its surroundings ignoring radiation is 332.67 W.

Explanation:

Given: Inner diameter = 0.9 m

q = 872 W/m^{3}

Now, radii is calculated as follows.

r = \frac{diameter}{2}\\= \frac{0.9}{2}\\= 0.45 m

Hence, the rate of heat transfer is as follows.

Q = q \times V

where,

V = volume of sphere = \frac{4}{3} \pi r^{3}

Substitute the values into above formula as follows.

Q = q \times \frac{4}{3} \pi r^{3}\\= 872 W/m^{3} \times \frac{4}{3} \times 3.14 \times (0.45 m)^{3}\\= 332.67 W

Thus, we can conclude that the total rate of heat transfer from the container to its surroundings ignoring radiation is 332.67 W.

<em><u>Incomple</u></em><em><u>te</u></em><em><u> </u></em><em><u>ques</u></em><em><u>tion</u></em><em><u>!</u></em>

you have to provide mass to get acceleration

as Newton's 2nd law, force=mass×accln

now,here force toward D is 100N,if it hav mass m

then accln will be 100/m

A 620 kg car is traveling at 24 m/s on horizontal ground when it starts up a 30 m high hill. The engine can produce up to 144,00
sweet-ann [11.9K]

Answer:

The kinetic energy of the car at the top of the hill is 140280 Joules.

Explanation:

Mass of the car, m = 620 kg

Speed of the car, v = 24 m/s

Height of the hill, h = 30 m

The engine can produce up to 144,000 J of work during that time, W = 144,000 J

We need to find the kinetic energy of the car at the top of the hill. It can be calculated using conservation of mechanical energy as :

(mgh+K)-\dfrac{1}{2}mv^2=144000

(620\times 9.8\times 30+K)-\dfrac{1}{2}\times 620\times (24)^2=144000

620\times9.8\times30+K=322560

K=140280\ J

So, the kinetic energy of the car at the top of the hill is 140280 Joules. Hence, this is the required solution.
