Which explanations provide support for continental drift theory? Check all that apply.
Dinosaurs lived on many continents.
Coal fields match up across continents.
Tropical plant fossils were found in Arctic areas.
Similar rock types are found across continents.
Evidence of glaciers can be found in South Africa.
Coal fields match up across continents.
Similar rock types are found across continents.
Tropical plant fossils were found in Arctic areas.
Evidence of glaciers can be found in South Africa.
<h3><u>
Explanation:</u></h3>
The way the continents on the earth shifts its position is explained by the Continental drift theory. Alfred Wegener was the one who fist proposed this theory in 1912. This theory also explains how similar rocks are formed on the different continents and also the reason why some of the animal and plant fossils looks similar.
The evidences that supports the continental drift theory can be Coal fields match up across continents. Fossils of Glossopteris supports the theory of continental drift with coal fields and coastlines
. The land features, climate changes are some of the evidences that also supports the theory of continental drift.The evidences of the glaciers that can be found in South Africa also supports the explanation of the continental drift.
Given:
Inductance, L = 150 mH
Capacitance, C = 5.00 mF
= 240 V
frequency, f = 50Hz
= 100 mA
Solution:
To calculate the parameters of the given circuit series RLC circuit:
angular frequency, 
= 
a). Inductive reactance, 
is given by:
b). The capacitive reactance, 
is given by:
c). Impedance, Z = 
d). Resistance, R is given by:
e). Phase angle between current and the generator voltage is given by:
Answer:
d 
= m× λ⇒ d = λ ×m×l / x
= 630×
m × 3×3m/ 45×
m
= 1.26×
m
Explanation:
the above calculation is based on Young’s double slit experiment where the two slits provide two coherent light sources which results either constructive interference or destructive interference when passing through a double slit.
Answer:
v₀ = 16.55 m/s
Explanation:
This motion of the ball can be modeled as a projectile motion with following data:
R = Range of Projectile = 27.5 m
θ = Launch Angle = 50°
g = acceleration due to gravity = 9.81 m/s²
v₀ = Initial Speed of Ball = ?
Therefore, using formula for range of projectile, we have:
<u>v₀ = 16.55 m/s</u>
