<span>During an exothermic process [heat flows from the system to the surroundings]. Exo roughly translates to outside, and thermic refers to heat. Heat is released from a system to its surroundings during an exothermic reaction, so the system would actually feel warm to the touch. The opposite of this is called and endothermic reaction.</span>

If BHALA AHMAD KHAN applied the 20N force is applied on an object moving with the velocity 30 m/s. calculate the power in KW.
Leokris [45]

Answer:0.6kw

Explanation:

Power=force×velocity

Power=20×30=600w

In kw it's going to be 600/1000=0.6kw

How much energy is required to ionize hydrogen when it is in the n = 5 state?
PtichkaEL [24]

Answer:

0.544 eV

Explanation:

To ionize the hydrogen atom n_f\rightarrow infinte

So the required energy is \Delta E=13.6(\frac{1}{n_i^2}-\frac{1}{n_f^2}) as  n_f\rightarrow infinte

So \Delta E=13.6\frac{1}{n_i^2}

We have to calculate the energy required to ionize hydrogen atom when it is in n=5

So the energy should be less than \Delta E=13.6\frac{1}{5^2}=0.544eV

A friend pushes a sled across horizontal snow and when it gets up to speed the friend jumps on. After the friend jumps on, the s
Shalnov [3]

Answer:

      v’ =( \frac{1}{1+ \frac{M}{m} }  )  v

we see that the greater the difference, the more the sled slows down.

friction force

Explanation:

When the man pushes the sled he does work and the sled acquires a speed and as long as it is supplied with an energy equal to the work of the chipping force with the snow, the speed is maintained.

When he jumps on the sled, a collision occurs and the initial moment

             p₀ = mv

is increased by the increase in mass

             m_f= (m + M_{man} ) v '

In this case there is no longer any external force applied and the only external force is friction, which causes the sled to stop, even when it is small, but the significant reduction in speed is due to the increase in masses.

            p₀ = p_f

            mv = (m + M_{man}) v '

            v ’=  \frac{m}{m+M} v

            v’ =( \frac{1}{1+ \frac{M}{m} }  )  v

Therefore, we see that the greater the difference, the more the sled slows down.

The only forces that act on the sled with the man are the friction that is responsible for the decrease in speed and weight with the normal
