<span>h = 1/2 * g t^2
= 1/2 * 9.8 * 3^2
= 44.1 m
d = vx * t = 20 * 3 = 60 m
Ans: 44.1 m, 60 m </span>
1. Air resistance force usually upwards, but gravity doenwards.
2. Objects are affected by gravity the same, but air resistance can affect the speed of an object's descent.
Sorry if im wrong
Answer:
6 V
Explanation:
In a circuit, the relationship between voltage, current and resistance is given by Ohm's law:

where
V is the voltage
R is the resistance
I is the current
In this circuit, we have
is the resistance
I = 0.500 A
so we can find the voltage of the battery by using Ohm's law:

The density of the substance is obtained by dividing its mass by its volume. Density is an intensive property which means that its value does not depend on the amount of substance and will always stay the same for same conditions.
d = 84.7 g / 46.7 cm³ = 7.75 g / x cm³
The value of x is approximately 4.27 cm³.
