Edward travels 150 kilometers due west and then 200 kilometers in a direction 60° north of west. What is his displacement in the

lions [1.4K]

We must decompose the displacement vector to find the new displacement to the west.

$d_{x}=v.cos\O \\ d_{x}=200. \frac{1}{2} \\ d_{x}=100km$

Adding all displacements to West, It comes:

$\Delta S= d_{o}+d_{x} \\ \Delta S= 150+100 \\ \boxed {\Delta S= 250 km}$

18. A circuit contains a 10 ohm resistor, a 50 ohm resistor, and an 80 ohm resistor connected in parallel. If you test this circ

lutik1710 [3]

The equivalent resistance is D) $7.55 \Omega$

Explanation:

The equivalent resistance of n resistors in parallel is given by the equation:

$\frac{1}{R}=\frac{1}{R_1}+\frac{1}{R_2}+...+\frac{1}{R_n}$

For three resistors such as in this problem, the equation becomes

$\frac{1}{R}=\frac{1}{R_1}+\frac{1}{R_2}+\frac{1}{R_3}$

where we have the following:

$R_1 = 10 \Omega$ is the resistance of the 1st resistor

$R_2 = 50 \Omega$ is the resistance of the 2nd resistor

$R_3 = 80 \Omega$ is the resistance of the 3rd resistor

Substituting, we find the equivalent resistance:

$\frac{1}{R}=\frac{1}{10}+\frac{1}{50}+\frac{1}{80}=0.133 \Omega^{-1}$

$R=\frac{1}{0.133}=7.55 \Omega$

Suppose all of the apples have a mass of 0.10 kg and one of the apples in the bowl (C) is 1.0 meter off the ground. If the apple

sesenic [268]

The answer is 0.981 J

E = m · g · h<span>
E - energy
m - mass
g - gravitational acceleration
h - height

We know:
E = ?
m = 0.10 kg
g = 9.81 m/s</span>²
h = 1 m

E = 0.10 kg * 9.81 m/s² * 1 m = 0.981 J
