Answer:
A. Wegener could not explain what made the continents move.
Explanation:
Answer:
31.2m/s
Explanation:
final velocity = initial velocity + acceleration • time
final velocity = 0 m/s + 6.58m/s/s • 4.74 s
final velocity = 31.2 m/s
Answer:
The core
Explanation:
The Sun's core is the central region where nuclear reactions consume hydrogen to form helium. These reactions release the majority of energy from the sun that ultimately leaves the surface as visible light.
Answer:
Length L=0.0125 m
Explanation:
Given data
Resistance R=0.11Ω
Temperature T=20°C
Resistivity of tungsten at 20°C p=5.6×10⁻⁸Ω.m²
Radius of filament r=0.09/2 =0.045 mm =0.045×10⁻³m
To find
Length of filament L
Solution
The Cross section of area of filament is given as:

The Resistance of a material is given as:
