1 mole of plutonium = 244 gm
3.6 kg of plutonium = 3.6 × 1000 = 3600 gm
Number of moles = 3600 ÷ 244 = 14.754 moles
One moles of plutonium contains protons = 
Total number of protons in 14.754 moles = 
Total number of protons in 14.754 moles = 
Total Positive charge = 
Total positive charge = 
C
Answer: Electrostatic force
Explanation :
Ionic compounds can be readily dissolved in water because of the high dielectric constant of water screens and decrease the Electrostatic force between the oppositely charged ions.
Since water is a polar molecule and has a high valued dielectric constant. Water makes a bond with ions when dissolved and reduces the electrostatic forces that hold in a solid structure.
Given what we know about volcanic formations, we can conclude that the Mt. St. Helens volcano was formed by the process described in option D, "Subduction an oceanic continental convergent boundary caused a mountain range to form and magma to come to the surface".
Mt. St. Helens is a volcano that falls under the category of a stratovolcano. Stratovolcanoes are volcanoes that commonly form at subduction zones. This process forms chains or clusters of mountains along the boundaries of tectonic plates, where oceanic crust is pulled under another type of crust. This process tends to form mountain ranges which contain volcanoes, such as:
- Cascade Range (To which Mt. St. Helens belongs)
- Los Andes
- Rocky Mountains
- Campania Mountain range
and so on.

Answer:
Each side of your brain contains four lobes. The frontal lobe is important for cognitive functions and control of voluntary movement or activity. The parietal lobe processes information about temperature, taste, touch and movement, while the occipital lobe is primarily responsible for vision.
Answer:
787528.7 J
Explanation:
Work done: This can be defined as the product of force and distance along the direction of force. The S.I unit of work is Joules (J).
From the question,
W = Tcos∅(d)............. Equation 1
Where W = work done, T = tension in the rope, ∅ = the angle of the rope to the horizontal, d = distance.
But,
d = v(t)..................... equation 2
Where v = velocity, t = time
Substitute equation 2 into equation 1
W = Tcos∅(vt)............. Equation 3
Given: T = 210 N, ∅ = 23°, v = 7 km/h = 1.94 m/s, t = 35 min = 2100 s
Substitute into equation 3
W = 210(cos23°)(1.94×2100)
W = 787528.7 J
