a slingshot consists of a light leather cup attached between 2 rubber bands. if it takes force of 32 N to stretch the bands 1,2 cm what is the equilibrium spring constant of the 2 rubber bands
Answers
The equivalent spring constant of the two rubber bands is 2667 N/m
We can solve the problem by using Hooke's law, which states that the strain of the material is proportional to the applied stress within the elastic limit of that material. This can be represented by the formula:
[tex]F=-kx[/tex]
where
F is the force applied to the rubber bands
k is the equivalent spring constant of the two rubber bands
x is the stretching constant of the two rubber bands
In this problem, we have been given the following values
F = 32 N is the force applied
x = 1.2 cm
= 0.012 m is the stretching of the bands
Solving for k, we find the equivalent spring constant of the two rubber bands:
[tex]k=\frac{F}{x}[/tex]
k=[tex]\frac{32}{0.012}[/tex]
k = 2667 N/m

Answers
It is possible to see a distinctive pattern of brilliant and dark fringes when monochromatic light reaches a distant screen through two small apertures. By superimposing overlapping light waves coming from the two slits, this interference pattern is produced.
What principle causes bands of light and darkness to alternate as light passes through two or more objects?On the lit screen, the intensity pattern that results is determined by the superposition principle. When an integral number of wavelengths (0,, 2,...) is equal to the difference in routes from the two slits to a spot on the screen, constructive interference occurs.

A team of furniture movers wishes to load a truck using a ramp from the ground to the rear of the truck. One of the movers claims that less work would be required to load the truck if the length of the ramp were increased, reducing the angle with respect to the horizontal. Is his claim valid? Explain.
Answers
Answer:
Yes, his claim is valid
Explanation:
mechanical advantage of an inclined plane = IMA = L/h
By lengthening L, you increase the IMA.
Also, IMA = Output force / Input force
Input force is less on a "shallow" inclined plane. Work = Fd, so if F is lower, Work is lower. The height (d) doesn't change, just the length of the ramp and the angle of the ramp.
rita accelerates a 0.40-kg ball from rest to 9.0 m/s during the 0.15 s in which her foot is in contactwith the ball. what average force does she apply to the ball during the kick?
Answers
Rita applies an average force of 24 Newton to the ball during the kick.
What is acceleration?Acceleration is rate of change of velocity with time. Due to having both direction and magnitude, it is a vector quantity. Si unit of acceleration is meter/second² (m/s²).
Given that Rita accelerates a 0.40-kg ball from rest to 9.0 m/s during the 0.15 s.
The acceleration of the ball = change in speed / time interval
= ( final speed - initial speed) / time interval
= ( 9.0 m/s - 0 m/s)/0.15 s
= 60m/s^2.
Hence, according to Newton's 2nd law of motion:
The average force applied to the ball = mass × acceleration

What is the inverse relationship between size of the wavelength frequency and energy?
Answers
The shorter the wavelengths and higher the frequency corresponds with greater energy. So the longer the wavelengths and lower the frequency results in lower energy. The energy equation is E = hν.
A wavelength's frequency and energy (E) drop as it gets longer. You may conclude from these equations that the wavelength gets shorter as the frequency rises. The wavelength lengthens as the frequency drops. The two main categories of waves are electromagnetic and mechanical. Frequency and Wavelength are mutually exclusive. The frequency and energy decrease as the wavelength increases. The frequency and energy increase with decreasing wavelength. Because the fraction decreases as the denominator increases, energy decreases as a result. As a result, the connection between energy and wavelength is inverse. These are the wavelength and energy frequency relationships.

Answer:
Greater energy is correlated with shorter wavelengths and higher frequencies. Therefore, lower energy is produced by longer wavelengths and lower frequencies. E = hv is the energy equation.
Explanation:
As a wavelength lengthens, its frequency and energy (E) decrease. These calculations may lead you to the conclusion that as frequency increases, wavelength decreases. As the frequency decreases, the wavelength grows longer. Electromagnetic and mechanical waves fall into the two primary groups. Wavelength and Frequency cannot coexist. As the wavelength lengthens, the frequency and energy decrease. As the wavelength decreases, the frequency, and energy rise. Energy diminishes as a result of the proportion decreasing as the denominator rises. The relationship between energy and wavelength is therefore inverse.

The potential for action of a target cell is increased by excitatory neurotransmitters. By promoting cell relaxation, inhibitory neurotransmitters reduce the potential activity of a receptor cell.

what are directions of acceleration and net force if the speed of an object is changing while rotating in a circular motion?
Answers
In circular motion, an object is constantly changing direction, so its acceleration is always directed towards the center of the circle. This type of acceleration is called centripetal acceleration.
The net force acting on the object is also directed towards the center of the circle and is called the centripetal force. The magnitude of the centripetal acceleration and the centripetal force depend on the speed of the object, the radius of the circular path, and the mass of the object. They can be calculated using the following formulas:
Centripetal acceleration (a):
a = v^2/r
where v is the speed of the object, and r is the radius of the circular path.
Centripetal force (F):
F = ma = m(v^2/r)where m is the mass of the object.
So, if the speed of an object is changing while it is rotating in a circular motion, the direction of the acceleration and the net force acting on the object will always be towards the center of the circle. The magnitude of the acceleration and the force will depend on the speed, radius, and mass of the object.

Answers
21.6ml volume of 0. 415 M silver nitrate will be required to precipitate as silver bromide all the bromide ion in 35.0ml of 0.128 M calcium bromide.
What is Molarity ?
Molarity is defined as the amount of solute (in moles)in per litre of solution. It is also known as molar concentration of a solution , It is expressed in mol/l .
M = n/V
(where n is the number of moles and V is the volume in litres.)
n = M * V
The molarity of calcium bromide is 0.128M and the volume given is 35 ml.
so, number of moles of calcium bromide is:
n = 0.128 * 35
= 4.48 millimoles
2AgNO₃(aq) + CaBr₂(aq) → 2AgBr(s) + Ca(NO₃)₂(aq)
For every 1 mole of calcium bromide, 2moles of silver nitrate is required, so for 4.48 millimoles of CaBr2, 8.96 millimoles of AgNO3 is needed.
Molarity of AgNO3 is given, 0.415 M and number of moles is 8.96 millimoles, so volume required is:
V = n/M
= 8.96/0.415
= 21.6 ml
