Answer:

In the given equation y=Asin(ωt−kx)

Since, trigonometric function is a dimensionless quantity. So, (ωt−kx)is also dimensionless quantity.

So,

(ωt−kx)=1

ωt=1

[ω]= <u>1</u>=[T] ^−1

[T]

kx=1

[k]= <u>1</u>=[L]^ −1

A 2.00-gram air inflated balloon is given an excess negative charge, q1 = -3.25 × 10-8 C, by rubbing it with a blanket. It is fo

Llana [10]

Answer:

The rod`s charge must be positive, because the gravity force is pointing downwards and the electrostatic force must be pointing upwards (in order to balance the gravity force)

The charge is q_2 = 1.667 times 10^(-7) C

Explanation:

F_e = F_g

where F_g = m g and F_e= (1/4 pi e_0)*(q_1*q_2)/d^2,

Hoover Dam on the Colorado River is the highest dam in the United States at 221m, with a power output of 680 MW. The dam generat

DiKsa [7]

Answer:

The power in this flow is $9.56\times10^{8}\ W$

Explanation:

Given that,

Distance = 221 m

Power output = 680 MW

Height =150 m

Average flow rate = 650 m³/s

Suppose we need to calculate the power in this flow in watt

We need to calculate the pressure

Using formula of pressure

$Pressure=\rho g h$

Where, $\rho$ = density

h = height

g = acceleration due to gravity

Put the value into the formula

$Pressure=1000\times9.8\times150$

$Pressure=1470000\ Nm^2$

We need to calculate the power

Using formula of power

$P=Pressure\times flow\ rate$

Put the value into the formula

$P=1470000\times650$

$P=9.56\times10^{8}\ W$

Hence, The power in this flow is $9.56\times10^{8}\ W$
