Answer:
270 m
Explanation:
Given:
v₀ = 63 m/s
a = 2.8 m/s²
t = 4.0 s
Find: Δx
Δx = v₀ t + ½ at²
Δx = (63 m/s) (4.0 s) + ½ (2.8 m/s²) (4.0 s)²
Δx = 274.4 m
Rounded to two significant figures, the displacement is 270 meters.
Light waves are transverse while sound waves are longitudinal. Light waves can travel in vacuum. Sound waves require a material medium to travel, and hence, cannot travel in vacuum. The speed of light in a medium is constant.

La respuesta es 3 ohmios
Resistencia total = (1/12 + 1/4) ⁻¹
= (1/3) ⁻¹
= 3 ohmios
Por ejemplo, dos resistencias, R1 y R2 están en serie, la resistencia combinada es R1 + R2.
Cuando se conecta en paralelo, la resistencia total es el recíproco de (1 / R1 + 1 / R2)
En este caso las resistencias están en paralelo
Espero que esto ayude, que tengas un día bendecido!
Answer:
Doubled
Explanation:
F = 1.8 x 10^-6 N, q1 = q2
The force between the two charges is directly proportional to the product of two charges and inversely proportional to the square of distance between them.
Now one of the charge is doubled but the distance remains same so the force between the two charges becomes doubled.
