Answer:
C) Divergent
Explanation:
Magma which is present in the underlying mantle comes out at divergent plate boundaries. The reason of coming out magma is that heat in the mantle makes the crust less dense. After coming out, magma cools down and solidifies to form a new ocean floor. Hence, divergent plate boundary is most closely related with formation of new ocean floor.
Answer:
85.654988MHz
Explanation:
f = C/λ
λ (Lambda) = Wavelength in meters
c = Speed of Light (299,792,458 m/s)
f = Frequency (MHz)
299,792,458 m/s. ÷ 3.5. = 85.654988MHz
Answer:
(a) emf = 0.507 V
(b) emf = 0.0507 V
(c) emf = 0.00234 V
Explanation:
Given;
number of turns of the coil, N = 40 turns
diameter of the coil, d = 11 cm
radius of the coil, r = 5.5 cm = 0.055 m
magnitude of the magnetic field, B = 0.4 T
The magnitude of the induced emf is calculated as;
(a) when the time, t = 0.3 s
(b) when the time, t = 3.0 s
(c) when the time, t = 65 s

Answer: The "raising pudding" atomic model</h2>
Explanation:
<u>During the 19th century the accepted atomic model, was Dalton's atomic model</u>, which postulated the atom was an <u>"individible and indestructible mass".</u>
However, at the end of 19th century J.J. Thomson began experimenting with cathode ray tubes and found out that atoms contain small subatomic particles with a negative charge (later called <u>electrons</u>). This meant the atom was not indivisible as Dalton proposed. So, Thomson developed a new atomic model.
Taking into consideration that at that time there was still no evidence of the atom nucleus, Thomson thought the electrons (with negative charge) were immersed in the atom of positive charge that counteracted the negative charge of the electrons. <u>Just like the raisins embedded in a pudding or bread.
</u>
That is why this model was called the <u>raisin pudding atomic model.</u>
I think the answer is:
B) oceanic crust-continental crust
