a)  The y-component of the protons' momentum as they leave the magnetic field is 8.8 x 10-21 kg m/s

b) The angle ϕ between the initial velocity vector of the proton beam and the velocity vector after the beam emerges from the field is  9.812821°

Since are given with the kinetic energy of  5.20 Mev (8.32X 10^-13J), and  a magnetic field of 0.0550 t in the z-direction.From the diagram we can see  that, p(Y) =mv sin θ

=> sin θ =1/R , where R = mv/eB

=>sin θ = eB/mv

=>eB= mv sin θ

=> Py(the momentum) = eB =1.60×10−19J*0.0550 =  8.8 x 10-21 kg m/s .In the second case, sin θ  =  eB/mv, since the kinetic energy is 5.20 Mev

=>1/2 mv² =  5.20 mev = 8.33132e⁻¹⁹

=> v = √(2* 8.33132e-19 / 1.6 x10⁻²¹) = 32.27 m/s²

Now sin φ = eB/mv

=>sin φ =  8.8 x 10-21/ 1.6 x10^-21* 32.27 = 0.17043

=>φ = sin-1(0.17043)  = 9.812821°

b). Turbulence try to decreases flow rate, so that the pressure must need to increase after more to compensate at 89%.

The primary unit of stress is the pascal, described because the stress exerted through a pressure of 1 newton perpendicularly upon a place of 1 rectangular metre. In North America, however, the United States Customary System is preferred.

This is primarily based totally on Imperial devices which includes the pound (lb) and inch (in) or foot (ft). First, the resistance of float is inversely associated with the radius of the pipe. In different words, because the radius increases, there's extra room for the fluid to float through, and consequently the float charge increases.

a). Let x be the radius

then [tex]r_{2}[/tex] = x-89

pressure is inversely proportional to radius so, since pressure is constant there will be no change.

Jan Baptista van Helmont's famous experiment incorrectly showed that the plants produce most of their mass from water.

In physics, mass is used to express inertia, a property common to all matter. In essence, it is the resistance of a mass of matter to changing its course or speed in response to the application of a force. The more mass a body has, the less of a change an applied force makes. Using Planck's constant, the kilogram, the ISU's unit of mass, is equivalent to 6.62607015 1034 joule seconds (SI). One kilogram is multiplied by one square meter per second to produce one joule. Since the second and the meter have already been defined in terms of other physical constants, the kilogram is determined by precise measurements of Planck's constant.

The maximum speed of the car was found to be 10.14 ms-1.

Define coefficient of static friction ?

A number that expresses how sticky an object is to its contact surface while it is stationary is known as the coefficient of static friction.

It is the ratio of the normal force imposed on the body to the static friction present between two contact surfaces.

Consider the three categories of dry friction: rolling friction, kinetic friction, and static friction.

Generally speaking, rolling friction and kinetic friction coefficients are lower than the coefficient of static friction.

Because static friction is greater than kinetic friction and rolling friction, this is the case.

This suggests that if an item is immobile, it will take greater effort to start it moving.

Rolling friction often has the least friction since it is greater in kinetic friction than rolling friction.

Depending on their mass and speed when they hit the ground, they would have impacted with a specific amount of kinetic energy.

The food bags would have been dropped with parachutes attached in the imagined scenario. The bags' descent would have been slowed by the parachutes, lowering the acceleration brought on by gravity.

The maximum possible distance in light-years of the alien civilization that sent the radio communication containing photos from the "I Love Lucy" episode "Vitameatavegamin" is approximately 22.1 light-years.

To determine the maximum possible distance in light-years of an alien civilization that has sent you a radio communication containing photos from the "I Love Lucy" episode "Vitameatavegamin," you can use the fact that light travels at a constant speed of approximately 299,792,458 meters per second.

Since the episode "Vitameatavegamin" first aired on May 5, 1952, the maximum possible distance in light-years of the alien civilization would be the distance that light could have traveled in the time since the episode aired.

To calculate this distance, you can use the following formula:

d = c × t

Where d is the distance in meters, c is the speed of light in meters per second, and t is the time in seconds.

To convert the distance from meters to light-years, you can use the conversion factor 1 light-year = 9.46 x 10^15 meters.

Plugging in the values for the speed of light and the time since the episode aired (70 years), we get:

d = 299,792,458 m/s × (70 years × 365 days/year × 24 hours/day × 3600 seconds/hour)

= 2.09 x [tex]10^{17}[/tex] meters

We can formulate the magnetic field's equation as follows based on the magnetic field's variation:

B(t) = B_c + B_o*sin (2πft)

B(t) = 2sin(2*10t) + 10

Thus;

dB/dt = 40π cos 20πt

When cos 20t = -1, the electric field is at its maximum value.

(dB/dt)_max = -40π

In most cases, at least a portion of the optical power of the light is reflected when it strikes a flat boundary between two different transparent materials. However, given a specific incidence angle known as Brewster's angle.

The refractive index of an optical material is a dimensionless quantity that indicates how well that material bends light. The refractive index controls how much light is refracted or curved when it enters a medium.
