A mass is attached to the end of a spring and set into simple harmonic motion with an amplitude A on a horizontal frictionless s

urface. Determine the following in terms of only the variable A.
(a) Magnitude of the position (in terms of A) of the oscillating mass when its speed is 50% of its maximum value.
(b) Magnitude of the position (in terms of A) of the oscillating mass when the elastic potential energy of the spring is 50% of the total energy of the oscillating system.

Answer:

Explanation:

Assuming  motion of equation of SHM as

x=A\cos \omega t

where, A=amplitude

\omega =angular\ frequency

t=time

thus velocity at any Point x is given by

v=\omega \Sqrt{A^2-x^2}

when speed is 50 % of its maximum value

v=0.5 A\omega

0.5 A\omega =\omega \Sqrt{A^2-x^2}

\frac{A^2}{4}=A^2-x^2

x=\frac{\sqrt{3}}{2}A

(b)When Potential Energy is 50 % of total energy

Total Energy =\frac{1}{2}kA^2

potential energy at any x is given by U=\frac{1}{2}kx^2

U=0.5\times \frac{1}{2}kA^2

\frac{1}{2}kx^2=0.5\times \frac{1}{2}kA^2

x=\frac{A}{\sqrt{2}}

How far apart would you have to place the poles of a 1. 5 v battery to achieve the same electric field?
Zarrin [17]

To place the poles of a 1. 5 v battery to achieve the same electric field is 1.5×10−2 m

The potential difference is related to the electric field by:

∆V=Ed

where,

∆V is the potential difference

E is the electric field

d is the distance

what is potential difference?

The difference in potential between two points that represents the work involved or the energy released in the transfer of a unit quantity of electricity from one point to the other.

We want to know the distance the detectors have to be placed in order to achieve an electric field of

E=1v/cm=100v/cm

when connected to a battery with potential difference

∆v=1.5v

Solving the equation,we find

d =  \frac{ \:Δv}{e}

=  \frac{1.5v}{100v/m}

= 1.5 \times 10 {}^{ - 2} m

A 0.350kg bead slides on a curved fritionless wire,
LuckyWell [14K]

Answer:

h2 = 0.092m

Explanation:

From a balance of energy from point A to point B, we get speed before the collision:

m1*g*h-\frac{m1*V_B^2}{2}=0  Solving for Vb:

V_B=\sqrt{2gh}=6.56658m/s

Since the collision is elastic, we now that velocity of bead 1 after the collision is given by:

V_{B'}=V_B*\frac{m1-m2}{m1+m2} = \sqrt{2gh}* \frac{m1-m2}{m1+m2}=-1.34316m/s

Now, by doing another balance of energy from the instant after the collision, to the point where bead 1 stops, we get the distance it rises:

m1*g*h2-\frac{m1*V_{B'}^2}{2}=0 Solving for h2:

h2 = 0.092m

Tasting and smelling both involve the ability to sense chemicals. true or false
lara31 [8.8K]
TRUE.
Taste and smell senses are separate senses with their own receptor organs yet they are intimately entwined. Tastants, chemicals in foods are detected by taste buds which consist of special sensory cells.. When stimulated, these cells send signals to specific areas of the brain which then makes us conscious of the perception of taste. Also specialized cells in the nose pick up odorants, airborne odor molecules. Odorants stimulate receptor proteins found on hairlike cilia at the tips of the sensory cells, a process that initiates a neural response.
