A pendulum with a length of 1.00 m is released from an initial angle of 15.0° and after 1000s , its amplitude has been reduced to 5.50°, where the value of the \frac{b}{2m} is 0.001 sec^{-1}.

The type of oscillation shown here is a damped oscillation, where slowly with respect to time, the amplitude of oscillation decreases.

In the damped oscillation, the position is determined according to the equation given below:

x(t)=Ae^{-\frac{bt}{2m} }

The given information:

l= 1.00 m\\x(0)=15^{o} \\x(1000)=5.50^{o}\\

So using the equation:

x(t)=Ae^{-\frac{bt}{2m} }

\frac{x(1000)}{x(0)} =\frac{Ae^{-\frac{b(1000)}{2m} }}{Ae^{-\frac{b(0)}{2m} }} \\\frac{x(1000)}{x(0)} =\frac{Ae^{-\frac{b(1000)}{2m} }}{Ae^{-\frac{b(0)}{2m} }} =\frac{5.50}{15}  \\\therefore e^{-\frac{b(1000)}{2m} } = =\frac{5.50}{15}  \\\therefore \frac{b}{2m} = 0.001 \ s^{-1} \\

Hence, the value of the \frac{b}{2m} is 0.001 sec^{-1}.

Radio waves are readily diffracted around buildings, whereas light waves are negligibly diffracted around buildings. This is bec
Tom [10]

Answer:

Radio waves have longer wavelength

Explanation:

Radio wave is an electromagnetic frequency that has the ability to travel through long distance. They have frequencies shuttling been the range of 10^4 hz and a frequency of 10^12 hz

Light wave is also called visible light. This is because it is visible to the naked eye, despite it being in the electromagnetic spectrum. It's frequency is usually between 4*10^-7 hz and a frequency of 7*10^-7 hz.

As can be seen from both, the radio waves length are quite far stronger than that of the light waves.

if a current of 0.3 ampere flows through a conductor of resistance of 11.7 ohm's,the voltage across the ends of the conductor is
Gnesinka [82]

Here,

Resistance = 11.7

Ampere = 0.3

Voltage = ?

Now,

R = V/A

11.7 = V/0.3

11.7*0.3 =V

V = 3.51

A force, F1, of magnitude 2.0 N and directed due east is exerted on an object. A second force exerted on the object is F2 = 2.0
IgorLugansk [536]

Answer:

Magnitude of the force is

F_3 = 2.83

direction of the force is given as

\theta = 45 degree West of South

Explanation:

As we know that force is a vector quantity and in order to find the resultant of two or more forces we need to add them vectorialy

So here we have

\vec F_1 + \vec F_2 + \vec F_3 = 0

here we know that first force is of magnitude 2 N towards east

\vec F_1 = 2 \hat i N

second force is also of 2.0 N due North

\vec F_2 = 2 \hat j

now from above equation

2\hat i + 2\hat j + \vec F_3 = 0

\vec F_3 = -2\hat i - 2\hat j

so magnitude of the force is given as

F_3 = \sqrt{2^2 + 2^2}

F_3 = 2.83

direction of the force is given as

\theta = tan^{-1}\frac{F_y}{F_x}

\theta = tan^{-1}\frac{-2}{-2}

\theta = 45 degree West of South

What would happen to the moon if earth stopped exerting the force of gravity on it?
Mila [183]
There are two equal forces of gravity between the Earth and the Moon.
One force pulls the Moon toward the Earth.
The other force pulls the Earth toward the Moon.

If only this gravity suddenly switched off, then the moon would
continue to orbit the Sun, very much as it does now.

If ALL gravity suddenly switched off, then . . .

-- the Moon would stop orbiting the Earth and would sail away, in
a straight line and at the speed it had when gravity disappeared;

-- the Earth would stop orbiting the Sun and would sail away, in
a straight line and at the speed it had when gravity disappeared;

-- all the gases surrounding the Earth ... which we call "air" ... would
start drifting away, and expanding into a giant cloud of gas, and stop
being an atmosphere;

-- the Sun would completely fall apart, expand into a giant cloud of gas,
and stop being a star.
