Answer:
I'm not going equal ieu heya
Answer:
Speed is a scalar quantity and does not keep track of direction; velocity is a vector quantity and is direction aware.
Explanation:
I hope this helps you!
The angle of the incidence (T) = 40°
Angle of refraction (r) = 26°
→To find the speed of light in the material
From shell's law, we know
n: sin i/sin = speed of light in air/Speed of light in the medium
Sin 40°/sin 60° = 3×10⁸/V
V = 3 × 10⁸× sin 26°/sin 40°
→ V medium = 2 × 10⁸ m/s.
Answer:
R = 0.75 ohms
Explanation:
Given that,
The voltage of each battery, V = 1.5 V
Current through the light bulb, I = 2 A
We need to find the resistance of the light bulb. We know that,
Ohm's law, V = IR
Where
R is the resistance of the light bulb
Put all the values,
So, the resistance of the light bulb is equal to 0.75 ohms.
