When a pulse travels on a taut string, does it always invert upon reflection? Explain.

If pulse travels on a taut string, it may or may not invert upon reflection because it is one that tends to depends on the place the wave reflects.

Hence, If reflecting is obtained from a less dense string, the reflected part of the wave will tend to be from be right side up. A wave inverts if only  it reflects off via a means in which the wave speed is said to be smaller.

<h3>When a wave pulse on a string reflects?</h3>

If a pulse on string is said to show or reflects from free end, the outcome of the resultant pulse is said to be made in such a way that the said slope of string is seen at free end is zero.

Therefore, If pulse travels on a taut string, it may or may not invert upon reflection because it is one that tends to depends on the place the wave reflects.  If reflecting is obtained from a less dense string, the reflected part of the wave will tend to be from be right side up. A wave inverts if only  it reflects off via a means in which the wave speed is said to be smaller.

Indiana jones (83.5 kg) is running 3.75 m/s when he jumps in a stationary 312 kg mine cart. what is their joint velocity afterwa
Lubov Fominskaja [6]

Answer:

.7917 m/s

Explanation:

This is a conservation of momentum question. You have an object initially at rest (cart) so that object is initially at 0 momentum. Indiana Jones is 83.5 kg and running 3.75 m/s so he starts with a momentum of 313.125 kg * m/s because momentum is equal to mass * velocity. Once the person jumps in the cart, the cart and the person can be considered one object and by conservation of momentum, the momentum of the Indiana-cart system is equal to 313.125 kg * m/s. By that, we can set that momentum equal to the combined mass * joint velocity. So 313.125 = (83.5kg + 312kg) * joint velocity. Then just solve for the velocity. The answer should be smaller than the intial velocity of the person of 3.75 m/s because the mine cart is HUGE at 312kg.

goblinko [34]

We have that the instantaneous velocity of the shuttlecock when it hits the ground is

V_{int}=\sqrt{U^2+19.6H}

From the question we are told

Assuming the acceleration is still -9.81 m/s2, what is the instantaneous velocity of the

shuttlecock when it hits the ground? Show your work below.

Generally the equation for acceleration  is mathematically given as

a=v \frac{dv}{dx}\\\\\Therefore\\\\\2ah=v^2-u^2

Where

acceleration is still -9.81 m/s2,

Hence,

V^2-U^2=2(-9.81)*-H

Therefore

V_{int}=\sqrt{U^2+19.6H}

A graph shows how the temperature of a substance changes as energy is added steadily over time.
OlgaM077 [116]

Answer:

A flat, horizontal line  

Explanation:

A flat, horizontal line indicates a phase change.

The temperature does not increase because the added heat goes into converting one phase into another.

A is wrong. A downward-sloping line indicates that the temperature is decreasing with time.

C is wrong. An upward-sloping line indicates that the temperature is increasing with time.
