Answer: True!
Explanation: The force is proportional to the square of the distance between 2 point masses
Becasue when you rubbed your hair while you were putting on your sweater it caused it to rub against together causing electricity thingy lol. and thats why your hair goes straigh tup.
Responder:
<h2>5 horas
</h2>
Explicación:
La velocidad se define como el cambio de distancia de un cuerpo con respecto al tiempo. Matemáticamente, Velocidad = Distancia / Tiempo
Dada la velocidad del coche = 0,25 km / hy la distancia = 1,25 km
El tiempo se expresa a partir de la fórmula como Tiempo = Distancia / Velocidad
La sustitución de los valores dados en la fórmula dará;
Tiempo = 1,25 km / 0,25 km / h
Tiempo = 5 horas
Por lo tanto, la tortuga tardará 5 horas en viajar a una velocidad de 0,2 km / h.
Answer:
20000 W
Explanation:
Power: This can be defined as the rate at which energy is dissipated or used. The S.I unit of power is Watt(W).
The expression of power is given as,
P = E/t.............................. Equation 1
Where P = power, E = Energy, t = time.
Given: E = 200 J, t = 0.01 s
Substitute into equation 1
P = 200/0.01
P = 20000 W.
Hence the average power = 20000 W
Answer:
15.8 N
Explanation:
The component in a given direction is the magnitude of the applied force, multiplied by the cosine of the angle between its application and the direction of interest.
The horizontal component is ...
(20 N)cos(38°) ≈ 15.8 N
