Answer:
A: Ions are attracted to each other → Electrons are transferred → An ionic compound forms. B: An ionic compound forms → Ions are attracted to each other → Electrons are transferred. C: Electrons are transferred → Ions form → Ions are attracted to each other.
Explanation:
Answer:
B. I, III and IV
Explanation:
The strength of the magnetic field generated by a solenoid is given by the following formula:
B = μ₀NI/L
where,
B = Magnetic Field
μ₀ = Permeability of Free Space
N = No. of Coils
I = Current Magnitude
L = Length of Coil
Strength is also directly proportional to size of the core.
So, to increase the magnetic field strength we can:
1- The number of Loops
2- Increase the amount of Current (for same length)
3- Decrease the length (for same number of loops)
4- Increase Size of Core
So, the correct answer is:
<u>B. I, III and IV</u>
1: B
2: C <span>Sediments were deposited in continuous sheets that spanned the body of water that they were deposited in</span>
3: A Erosion is the action and movement of a surface process
A would be the answer because thats how long it takes
Density- It is a measurement of that how material is packed together tightly.
Its formula is ρ=m/v
where ρ is the density of material
m is the mass
v is the volume
here we have to find the length of cube's side
a cube of silver has a mass = 21 kg. = 21×10³ [∵1kg = 1000g ]
density of silver = 10.49g/cm³
the length of the cube's side = ?
v=m/ρ
l³ = 21×10³ /10.49 ≈ 2×10³ cm³
l =∛(2×10³)cm³
l = 1.26 ×10 = 12.6 cm
l = 4.96 inches [∵ 1 cm = 0.394 inch ]
the length of the cube's side is 4.96 inches
