Answer:

R = 4.77 ohms

Explanation:

Four resistors are given such that,

R₁ = 2 ohms

R₂ = 3 ohms

R₃ = 5 ohms

R₄ = 10 ohms

Here, R₁ and R₂ in series. The equivalent is given by :

R₁₂ = R₁ + R₂

= 2 + 5

R₁₂ = 7 ohms

Similarly, R₃ and R₄ are in series. so,

R₃₄ = R₃ + R₄

= 10+5

R₃₄ = 15 ohms

Now, R₁₂ and R₃₄ are in parallel. So,

\dfrac{1}{R}=\dfrac{1}{R_{12}}+\dfrac{1}{R_{34}}\\\\\dfrac{1}{R}=\dfrac{1}{7}+\dfrac{1}{15}\\\\R=4.77\ \Omega

So, the equivalent resistance s 4.77 ohms.

1. A 0.250 kg baseball sits on the ledge of a window in Treadwell hall. If the ball has 18.5
Lunna [17]

Answer:

h = 7.54 m

t = 1.24 s

Explanation:

1.Let g = 9.81 m/s2 is the gravitational acceleration. Since the formula for potential energy is:

E_p = mgh

where m = 0.25 is the ball mass and h is the height. We can solve for h

h = \frac{E_p}{mg} = \frac{18.5}{0.25*9.81} = 7.54m

2. The time it take for the ball to reach a distance of 7.54m with a gravitational acceleration of 9.81m/s2:

h = \frac{gt^2}{2}

t^2 = \frac{2h}{g} = \frac{2*7.54}{9.81} = 1.54

t = \sqrt{1.54} = 1.24 s

A thin, uniform metal bar, 2.00 m long and weighing 90.0 N, is hanging vertically from the ceiling by a frictionless pivot. Sudd
matrenka [14]

Answer:

(a) The "angular speed" is 5.88 rad/s.

Explanation:

Given values,

The length of the bar is L = 2m

The weight of the bar is w = 90 N

The metal bar is hanging vertically from the ceiling by a frictionless pivot  

The mass of the ball is m = 3kg

The distance between the ceiling and the ball is d = 1.5m

\text { The "initial speed of the ball" is } V_{i}=10 \mathrm{m} / \mathrm{s}

\text { The "final speed of the ball" is } V_{f}=6 \mathrm{m} / \mathrm{s}

(a) Calculating the angular speed:    

W_{\mathrm{f}}=\left(3 \mathrm{mg} \mathrm{d} \frac{V_{i}+V_{f}}{w l^{2}}\right)

W_{f}=\left(3 \times 3 \times 9.8 \times 1.5 \times \frac{10+6}{90 \times 2^{2}}\right)

W_{f}=\frac{2116.8}{360}

\mathrm{W}_{\mathrm{f}}=5.88 \mathrm{rad} / \mathrm{s}

The angular speed is 5.88 rad/s.

(b) The "angular momentum" is conserved because the torque is not exerted by "the pivot" on the system about the "axis of rotation" but the "linear momentum" is not conserved because "the pivot" exerts a "vertical" and a "horizontal force" on the system during the collision.

answer key to Student Exploration: Feed the Monkey (Projectile Motion) page 3 Activity B Question: As the banana flies through s
murzikaleks [220]

As the banana flies through space, up the red arrow showing its path of motion takes a curved or parabolic shape.

<h3>What is a projectile?</h3>

A projectile is an object launched into space at an angle to the horizontal ground and allowed to fall freely under gravity.

The path of motion of a projectile is parabolic.

Examples of objects that are projectiles include:

  • A thrown banana
  • A kicked football
  • An arrow shot from a bow

Therefore, as the banana flies through space, up the red arrow showing its path of motion takes a curved or parabolic shape.

What is the formula for Impedance for circuit with R, C, and L?
NikAS [45]

Answer:

 The formula for Impedance for circuit with R, C, and L are:

    z=\sqrt{R^{2}+\left ( \omega L-\frac{1}{\omega C} \right )^2}

The impedance Z of the series RLC circuit depend upon angular frequency ω. Impedance is measured in ohms and resistance (R), inductance reactance and capacitive reactance. Series RLC circuit consist of the resistance, a capacitance and an inductance connected in the circuits. Electrical impedance is the measurement of the opposition that a circuit present in a current.
