Here in all nuclear reactions we can say that mass conservation and charge conservation is always true

Here iron nuclei smashed into lead nuclei and then a new nuclei will form which will released along with a neutron

Now in this reaction mass and charge will remain conserved

mass number of iron + mass number of lead = mass number of new nuclei + mass number of neutron

58 + 208 = x + 1

x = 265

so the new nuclei formed will have mass number A = 265

now we will use charge conservation

Number of protons in iron + number of protons in lead = number of protons in new nuclei + number of protons in neutron

26 + 82 = z + 0

z = 108

so the new nuclei will form with atomic number z = 108 and mass number A = 265

If we refer periodic table to find such atom we will see that this is $^{265}Hs$

so the new nuclei formed is $^{265}Hs$

State an advantage of using such hydraulic jack to lift a load

expeople1 [14]

Answer:

Explanation:

You are going to lift and press down on the 200 N many times and move only a short distance. The reward is that slowly but surely you will lift a very heavy load -- one that cannot be managed any other way but by the hydraulic jack.

A train moving at a constant speed on a surface inclined upward at 10.0° with the horizontal travels a distance of 400 meters in

Amiraneli [1.4K]

If the velocity of the train is v=s/t, where s is the distance and t is time, then v=400/5=80m/s. To get the vertical component of the velocity we need to multiply the velocity v with a sin(α): Vv=v*sin(α), where Vv is the vertical component of the velocity and α is the angle with the horizontal. So:

Vv=80*sin(10)=80*0.1736=13.888 m/s.

So the vertical component of the velocity of the train is Vv=13.888 m/s.
