If the object sinks, then it must be heavier than the weight of the water
it displaces ... heavier than the buoyant force acting on it.
If the buoyant force were equal or greater than the object's weight, then
the object would rise to the surface in water.
Answer:
It would take the cyclist 2 hours to cycle to school.
Explanation:
5km/hr for 2 hours would be 10km.
Explanation:
You are given the initial velocity, the displacement, and the acceleration. You're looking for the final velocity. So you use the equation:
v² = v₀² + 2aΔy
When you solve for v, you take the square root. Your calculator will return a positive answer, but there are actually two possible answers: positive and negative.
v = ±√(v₀² + 2aΔy)
You must use the physical context of the problem. If we take up to be the positive direction, then v must be negative, since the projectile is moving down.
Answer:
B) It is connected in parallel and measures potential differences.
Explanation:
A voltmeter measures electrical potential differences between two points in an electric circuit. It is also connected in parallel to measure a device's voltage, while an ammeter is connected in series to measure a device's current.
Hope this helps! :)
