One solution to this problem is measuring water displacement.
If you put the irregularly shaped object in water, then measure the volume of the displaced water, you will have the volume of the irregular object.
Thank you for posting your question here. Below is the solution:
fbeat = (f' - f) / 2
<span>then </span>
<span>f' = 2 fbeat + f = 4.126 Hz </span>
<span>also </span>
<span>f' = f vs / (vs - v) </span>
<span>then </span>
<span>v = (f' - f) vs / f' </span>
<span>v = (4.126 - 4)*340 / 4.126 = 10.383 m/s</span>
The picture of the dog will frame behind the mirror. Just a concave mirror is equipped for delivering a genuine picture and this lone happens if the question is found a separation more noteworthy than a central length from the mirror's surface.
Answer:
a)
Nm⁻¹
b)
Hz
c)
ms⁻¹
d)
m
e)
ms⁻²
f)
m
Explanation:
a)
= force required to hold the object at rest connected with stretched spring = 27 N
= stretch in the spring from equilibrium position = 0.2 m
= force constant of the spring
force required to hold the object at rest is same as the spring force , hence
inserting the values
Nm⁻¹
b)
frequency of the oscillations is given as
inserting the values
Hz
c)
= Amplitude of oscillations = 0.2 m
= angular frequency
Angular frequency is given as
rads⁻¹
Maximum speed of oscillation is given as
ms⁻¹
d)
maximum speed of the object occurs at the equilibrium position, hence
m
e)
Maximum acceleration of oscillation is given as
ms⁻²
f)
maximum acceleration occurs when the object is at extreme positions, hence
m
For the purpose of lifting heavy loads, a block and tackle pulley system consists of two or more pulleys connected by rope or cable. These pulleys are put in a block configuration and connected so that one pulley is stationary and moves with a load.
Threading the rope through the pulley, which increases the force applied to the rope, provides mechanical advantage. Usually, heavy lifting or applying a lot of force in either direction requires the employment of these pulleys.
Examples of block and tackle pulleys are shown below.
Step pulley
This can be thought of as a collection of pulleys. With pulleys of various diameters fixed in order, pulley faces are converted into step pulleys. It is known as a step pulley because of the way it is constructed.
“V” Groove Pulley
This pulley's face has a groove cut into it that resembles the English letter "V." Both electric motors and cars use it. These pulleys utilize a unique "V"-shaped belt. More than one "V" groove may be cut in some pulleys.
These pulley types are utilized for heavy duty power transfer. Less power slippage is possible when many "V" belts are being used.
