What makes infrared waves different from other waves?
Infrared rays have longer wavelengths than visible light and can pass through dense regions of gas and dust in space with less scattering and absorption. So, infrared objects can reveal objects in the universe that cannot be seen in visible light using optical telescopes.
The wavelengths of infrared waves range between 700 nm to 1 mm. They are longer than visible rays but shorter than radio waves. They are not visible by human eye.
Infrared radiation can promote local blood circulation and reduce muscle tension. Examples of traditional medical applications of infrared radiation include the relief of muscle pain and tension, as well as auto immune diseases or wound healing disorders.

There is strong evidence that Europa, a satellite of Jupiter, has a liquid ocean beneath its icy surface. Many scientists think we should land a vehicle there to search for life. Before launching it, we would want to test such a lander under the gravity conditions at the surface of Europa. One way to do this is to put the lander at the end of a rotating arm in an orbiting earth satellite. If the arm is 4.25 m long and pivots about one end, at what angular speed (in rpm) should it spin so that the acceleration of the lander is the same as the acceleration due to gravity at the surface of Europa? The mass of Europa is 4.80 x 10^{22} kg and its diameter is 3120 km.
The angular speed of the lander at the end of the rotating arm is 4.98 rpm.
It is given to us that -
The radius of the rotating arm = 4.25 m
Mass of the Europa = [tex]4.80 * 10^{22}[/tex] kg
Diameter of the Europa = 3120 km
=> Radius of the Europa = 3120/2 = 1560 km = 1,560,000 m
We have to find out the angular speed (in rpm) at which the rotating arm should spin so that the acceleration of the lander is the same as the acceleration due to gravity at the surface of Europa.
Firstly, we have to find out the acceleration due to gravity of the Europa. We know that the force on the Europa can be given as -
[tex]F = Mg\\= > Mg = \frac{G*m*M}{R^{2} } \\= > g = \frac{G*m}{R^{2}}\\= > g = \frac{(6.67 * 10^{-11} )*(4.80*10^{22} )}{1560000^{2} } \\= > g = 1.19 m/s^{2}[/tex] ----- (1)
It is given to us that -
Acceleration of the lander = Acceleration due to gravity at the Europa
[tex]= > a_{l} = g\\= > a_{l} = 1.19 m/s^{2}[/tex] ----- (2) [From equation (1)]
Now, to calculate the angular speed of the lander, we can use the formula as -
[tex]= > a_{l} = w^{2} r\\= > w^{2} = \frac{a_{l} }{r} \\[/tex] ----- (3)
where,
[tex]a_{l}[/tex] = Acceleration of the lander
[tex]w[/tex] = angular speed of the lander
r = radius of the rotating arm
Substituting the values of [tex]a_{l}[/tex] from equation (2) and r in equation (3), we have -
[tex]w^{2} = \frac{a_{l} }{r}\\= > w^{2} = \frac{1.19 }{4.25}\\= > w^{2} = 0.28\\= > w = 0.529 rad/s[/tex]
In order to convert the angular speed in rpm, we have to use -
[tex]w = 0.529 rad/s\\= > w = 0.529 * \frac{1 rev * 60 s}{2\pi rad*1 min}\\ = > w = 4.98 rpm[/tex]
Therefore, the angular speed of the lander at the end of the rotating arm is 4.98 rpm.

The air bag reduces the force by increasing the time it takes the passenger to stop moving.
How does airbag make people safer ?Despite the fact that airbags are a widespread and necessary safety feature, few of us understand how they function in our cars. A processing unit chooses which airbags in the automobile to deploy in a crash based on data from any of a myriad of sensors.Depending on the severity of the crash, the frontal airbags can deploy with varied degrees of force. When the threshold is exceeded, an electrical pulse ignites a gas, triggering the airbags. This generates enough nitrogen gas in less than 30 milliseconds to fully inflate the airbag. Some airbags only deploy if the weight of a passenger in the relevant seat is detected, which means an airbag will not deploy if there is no passenger to protect.When you are involved in an automobile accident, airbags inflate when a sensor connected to your vehicle's airbag senses a collision. They are filled with nitrogen gas and deflate when the driver or passengers come into touch with the airbag.What is airbag system ?They're air cushions inflated in fractions of a second by a fast-acting inflator to protect you from your car's interior hardpoints, such as the dashboard, steering wheel, windscreen, and roof pillars, which are triggered during an accident.

A container in the form of a right circular cone when the water is 8 m deep, the water level is rising at approximately 1.273 m/min.
The volume of a cone is:
V(h) = (1/3) × π × r² × h
V(h) = (1/3) × (4²) × h
V(h) = (16/3) × π × h
The rate at which the volume is changing with respect to time is:
dV/dt = 16 m³/min
dV/dt = (d/dt) [(16/3) × π × h]
dV/dt = (16/3 × π × (dh/dt)
(16/3 × π × (dh/dt) = 16
dh/dt = (16/3π)

For a concave mirror, the object-image connection is given by,
1 ÷ s + 1 ÷ s' = 2 ÷ R
the object distance, where s
The picture distance is s'.
The radius of curvature is R.
Now, the distance between an item and the point of curvature equals the radius of curvature.
s = R
Using s = R as a substitute and solving for s'
s' = [tex]((\frac{2}{R} ) - (\frac{1}{s} ))^{-1}[/tex]
s' = [tex]((\frac{2}{R} ) - (\frac{1}{R}))^{-1}[/tex]
s' = [tex]{(\frac{1}{R})}^{-1}[/tex]
s' = R
As a result, the photograph is real and can be found at R.

if the magnitude of the magnetic field is now decreased at a rate of -0.16 t/s , what force (magnitude and direction) will act on q ?
The magnitude of the force acting on q will be 0.16 t/s times the magnitude of the charge q, and it will be in the opposite direction of the magnetic field.
The force on a charged particle in a magnetic field is given by the equation:
F = qv × B
where q is the charge of the particle, v is the velocity of the particle and B is the magnitude of the magnetic field.
When the magnitude of the magnetic field is decreased at a rate of -0.16 t/s, the force on the particle will be in the opposite direction of the decreasing magnetic field. This is because the magnitude of the magnetic field will be decreasing over time, so the force on the particle will be in the opposite direction of the decreasing magnetic field.
The magnitude of the force acting on the particle will be equal to the product of the charge of the particle and the velocity of the particle multiplied by the rate of change of the magnetic field. That is, the magnitude of the force will be:

At this point, v = 39.0 m/s - (52.0 m/s) = 91 m/s.
Because the ball ultimately moves in this same reverse direction since making contact to it, 52 is negative.
F = 13195N
Any impact which could alter an item 's movement is referred to as a force in physics. Every body having weight can modify the velocity, or accelerate, in response to something like a force by shifting away off rest, for example. Subjectively, a concerted effort or a pull may also be employed to represent force.
As a vector quantity, a force is one that has simultaneous magnitude and direction. It is calculated using newtons as the SI unit of measure (N). It is a mechanically accepted quantity. F is a symbol that stands for force (formerly P).

Calculate the velocity of a non-relativistic electron whose de broglie wavelength is 3.637 nm.
The velocity of a non-relativistic electron whose de Broglie wavelength is 3.637 nm is 5.82 x 10^6 m/s.
The velocity of a non-relativistic electron can be calculated using the formula
v = h / mλ
where
h = Planck's constant
m = the mass of the electron
λ = the de Broglie wavelength of the electron.
Now using the above formula, we can easily find the velocity.
We know that the mass of the electron is 9.11 x 10^-31 kg,
the velocity of the electron can be calculated as follows:
v = (6.63 x 10^-34 m^2 kg / s) / (9.11 x 10^-31 kg * 3.637 x 10^-9 m)
This comes out to be approximately 5.82 x 10^6 m/s.
Therefore, the velocity of a non-relativistic electron whose de Broglie wavelength is 3.637 nm is 5.82 x 10^6 m/s.
