Answer:
Explanation:
The formula to find Potential Energy is PE = mgh, where m is the mass of the object, g is gravity, and h is the height from which the object can potentially fall. Because this is linear, then PE will increase as either the mass or the height increase (gravity is constant at 9.8 m/s/s). If the mass of the ball being dropped doesn't change, then the only thing that determines this ball's max PE is the height from which it is dropped; max PE ALWAYS occurs at the highest point from which an object can potentially fall. So your answer is "At the top".
If voltage is doubled<span> then let the new </span>voltage<span> be such that . ... Thus, the </span>current<span> flowing </span>through<span>the </span>circuit<span> will be </span>doubled<span> if </span>voltage<span> applied across the </span>circuit<span> is </span>doubled<span>.</span>
We have: Gravitational Potential Energy (U) = mgh
Here, m = 3 Kg
g = 9.8 m/s² [ constant value for earth system ]
h = 3 m
Substitute their values into the expression:
U = 3 × 9.8 × 3
U = 88.2 J
In short, Your Answer would be 88.2 Joules.
Hope this helps!
Speed (velocity)=distance/time
V1=98km/4hr=24.5km/hr
V2=61km/3hr=20.3km/hr
Average speed (velocity)=total velocity/ number
Average speed (velocity)=44.8km/hr/2=22.4
So the average speed is 22.4km/hr
Answer:
Explanation:
Let the race be of a fixed distance x
Troy's Average speed = 3 miles/hr = x / 0.2 hr
x = 0.6 miles
Abed's Average speed = 0.6 / 0.125 = 4.8 miles/hr
