Answer:
(a) v = 32 t
h = 16 t^2
g = 32 ft/s^2
(b) 64 ft/s
Explanation:
height, h = 64 feet
g = - 32 ft/s^2
(a) Let the time is t .
Let the velocity after time t is v.
Use first equation of motion
v = u + at
- v = 0 - 32 t
v = 32 t
Let the distance is h from the top.
Use second equation of motion
The acceleration is constant for entire motion.
(b) Let the velocity is v as it hits the ground. Use third equation of motion
Answer:
Explanation:
According to ohm's law current flowing in a conductor is directly proportional to the voltage applied across two end of conductor.
i.e.
where R=resistance
whee L and d are length and Diameter
thus
where k=constant of Variation
Distance is the physical length travelled. While the displacement is the shorter distance between any two given points.
<h3>What is distance?</h3>
Distance is a numerical representation of the distance between two objects or locations.
Distance can refer to a physical length or an estimate based on other factors in physics or common use. |AB| is a symbol for the distance between two points A and B.
Displacement is defined as the shortest distance between the two points.
Sam determines the distance by doing the calculation as;
distance = speed × time
Hence, the Sam determines the distance and displacement by the respective formulas.

Answer: B.)He should wire each room in parallel with the next
Explanation:
The voltage across each component connected in parallel is same. When a component in a parallel circuit, it does not effect working of other components. On the other hand, when a component in series circuit is switched off, whole circuit breaks and other components stop working as well. Thus, in order to create a plan that will allow the homeowners to turn off lights in one room without turning the light off the lights in another, he should wire each room in parallel with the next. Option B is correct.
