Determine the equivalent capacitance between points a and <br> b.

You are conducting an experiment inside a train car that may move along level rail tracks. A load is hung from the ceiling on a

Triss [41]

Here the weight is hung from the thread inside the ceiling of train

now the FBD of train is analysed

We can say

$Tcos\theta = mg$

$Tsin\theta = ma$

now by ratio of two equations we have

$a = gtan\theta$

this shows that train must be in accelerating condition due to which the thread is making an angle with the vertical

now we will have

2 The train is not an inertial frame of reference.

Since train is accelerating so it must be non inertial frame

5 The train may be moving at a constant speed in a circle.

Since its moving in circle so it is in accelerating condition

8 The train must be accelerating.

What is the scientific definition of energy that relates it to work? the ability to use an applied force to make an object move

Musya8 [376]

the ability to use an applied force to make an object move

Explanation:

The scientific definition of energy that relates it to work is the ability to use an applied force to make an object move.

Energy is defined scientifically as the ability to do work.
Work done is the force applied to make an object move in a specific direction.

Work done = Force x distance

Since energy is the ability to do work, we are are correct to say energy is also the ability to use an applied force to make an object move.

2. Derive a formula for the speed of the wave in terms of the fundamental frequency f1 and the string length L, and enter it bel

grigory [225]

Answer:

The speed of the wave is $f_{1}2L$

Explanation:

Given that,

Frequency = f

String length = l

We need to drive a formula of the speed of the wave

Using formula of fundamental frequency

$f=\dfrac{v}{\lambda}$

We know that,

$\lambda=2L$

$f=\dfrac{v}{2L}$

Where, v = speed of wave

$\lambda$ = wavelength of the wave

f = frequency

The speed of the wave is

$v=f_{1}2L$

Hence, The speed of the wave is $f_{1}2L$

(5 pt) You tie a cord to a pail of water, and your swing the pail in a vertical circular 0.700 m. What is the minimum speed must

Bas_tet [7]

Answer:

The minimum speed required is 2.62m/s

Explanation:

The value of gravitational acceleration = g = 9.81 m/s^2

Radius of the vertical circle = R = 0.7 m

Given the mass of the pail of water = m

The speed at the highest point of the circle = V

The centripetal force will be needed must be more than the weight of the pail of water in order to not spill water.

Below is the calculation:

$\frac{mV^{2}}{R} = mg$

$V = \sqrt{gR}$

$V = \sqrt{9.81 \times 0.7}$

$V = 2.62 m/s$

How can i tell on a position-time graph if it is speed or acceleration

Marrrta [24]

You didn't say what "it" is.

On a position/time graph, the slope of the graph at any point is the speed
at that time.

If you want acceleration, then what you'd have to do is to measure the slope
at every point on the position/time graph, then use that information to draw
a speed/time graph. The slope at every point on the speed/time graph is
the acceleration at that time.
