Answer:
The first law states that if the net force is zero, then the velocity of the object is constant.
Answer:
75 W
Explanation:
= temperature of the filament = 2100 K
= Emitting area of the filament = 1 cm² = 10⁻⁴ m²
= Emissivity = 0.68
= Stefan's constant = 5.67 x 10⁻⁸ Wm⁻²K⁻⁴
Using Stefan's law, Power output of the light bulb is given as
i don't know sorry

Answer:
b) a compound which produces ions dissolved in a solution that conduct electricity.
NaCl is an electrolyte.
My answer is. Acceleration is the difference between velocities at two times divided by the difference in the times.
