A satellite travels with a constant speed |v| as it moves around a circle centered on the earth. How much work is done by the gr

7nadin3 [17]

Answer:

W = 0

Explanation:

As the satellite moves in a circle the force is perpendicular to the path, therefore the work that is defined by

W = F. r = f r cos θ

Since the force and the radius are perpendicular, the angle θ = 90º and the cosine 90 = 0, therefore there is no work for the circular motion.

W = 0

A square wave has amplitude 0 V for the low voltage and 4 V for the high voltage. Calculate the average voltage by integrating o

Margarita [4]

Answer:

V_{average} = $\frac{1}{2} V_o$ , V_{average} = 2 V

Explanation:

he average or effective voltage of a wave is the value of the wave in a period

V_average = ∫ V dt

in this case the given volage is a square wave that can be described by the function

V (t) = $\left \{ {{V=V_o \ \ \ t< \tau /2} \atop {V=0 \ \ \ \ t> \tau /2 } } \right.$

to substitute in the equation let us separate the into two pairs

V_average = $\int\limits^{1/2}_0 {V_o} \, dt + \int\limits^1_{1/2} {0} \, dt$

V_average = $V_o \ \int\limits^{1/2}_0 {} \, dt$

V_{average} = $\frac{1}{2} V_o$

we evaluate V₀ = 4 V

V_{average} = 4 / 2)

V_{average} = 2 V

A viscous fluid is flowing through two horizontal pipes. The pressure difference P1 - P2 between the ends of each pipe is the sa

777dan777 [17]

Answer:half of shorter Pipe

Explanation:

Fluid is Flowing through two horizontal pipes with pressure difference

$P_1-P_2=\Delta P$

Both pipes have same radius

Length of one Pipe is twice of other

Let Longer Pipe be denote by 1 and smaller by 2

From Hagen Poiseuille equation

$\Delta P=\frac{128\mu L\cdot Q}{\pi D^4}$

Where $\mu =$ viscosity of medium

L=length of Pipe

Q=discharge

D=diameter

For longer Pipe

$\Delta P=\frac{128\mu 2L\cdot Q_1}{\pi \cdot D^4}$ ----1

For smaller Pipe

$\Delta P=\frac{128\mu L\cdot Q_2}{\pi \cdot D^4}$ ------2

From 1 & 2 we get

$2L\cdot Q_1=L\cdot Q_2$

$Q_2=2Q_1$

volume flow rate of longer pipe is half of smaller pipe

Why is gymnastics often considered to be the purest of all sports or athletic activities

Pachacha [2.7K]

To my knowledge, it isn't.

But I can provide reasons to defend this statement, including how gymnastics provides many benefits to our physical and mental health. It aids us in flexibility, coordination, discipline, and more. It keeps us socially healthy and capable with teams, friends, and competitions.

What acceleration will you give to a 27.8 kg

stich3 [128]

Answer:

2.72m/s²

Explanation:

Given parameters;

Mass of box = 27.8kg

Force on box = 75.7N

Unknown:

Acceleration = ?

Solution:

Force is the product of mass and acceleration;

Force = mass x acceleration

Now insert the parameters and solve;

75.7 = 27.8 x a

a = $\frac{75.7}{27.8}$ = 2.72m/s²
