ignoring air resistance a projectiles vertical speed will what?

Answers

Answer 1

In the absence of air resistance, the only force acting on both objects would be gravity. Both objects would experience the same 9.8 m/s² acceleration toward the ground.

Since the initial conditions of both projectiles are identical, the velocities of both projectiles will be the same at all times. Therefore, both projectiles will attain a zero vertical velocity at the same time, and it is at this point that they simultaneously reach their respective maximum heights.

The maximum heights will not be the same, and they will differ by precisely the amount of height difference between the launch points.

a ray of green light travels through air and is refracted as it enters a glass prism shown in the figure. an unknown liquid is in contact with the right side of the prism. the light then follows the path shown. which one of the following statements concerning this situation is true? a) the frequency of the light changes inside the prism. b) the index of refraction of the glass is smaller than that of air. c) the index of refraction of the unknown liquid is the same as that of the glass. d) the speed of light is larger in the liquid than in the glass. e) the refractive index of the liquid is the same as that of air.

Answers

Option C, Since there is no refraction and light travels in almost the same direction in both the glass as well as the unknown liquid, their indexes of refraction are identical.

Moving from the atmosphere to the glass causes the light to slow down. A prism's angle is 60 degrees, and its green light refractive index is 1.5.

The many media, or matter particles, through which light passes were used to gauge both its speed and how it appears to the human eye. To discern the different light wavelengths, the speed should slow down when the white light is revealed via the prism.

The following formula is used to get the refractive index:

what is the typical power radiated by an ils localizer? what is the potential problem with an ils localizer assigned to 108.1 mhz and a nearby fm broadcast station assigned to 107.7 mhz (hint: what is the typical power radiated by fm radio stations)?

Answers

The transmitters operate between 190 and 535 kHz, have a range of at least 15 miles, and have a power of less than 25 watts.

A localizer's sensitivity range.

The localizer course is typically 5°, which is fairly narrow. High needle sensitivity follows from this. When the airplane is 2.5° to either side of the centerline with this course width, a full-scale deviation is visible. This sensitivity enables precise alignment to the runway for landings.

Operating between the frequencies of 108.10 MHz and 111.95 MHz, the localizer transmitter uses one of the 40 ILS channels. Signals give the pilot direction to the middle of the runway.

An instrument landing system is a precise runway approach device that uses two radio beams to give pilots horizontal and vertical guidance as they approach the landing. The glideslope (GS) defines the proper vertical descent profile, while the localizer (LOC) offers azimuth guidance.

For instance, when we apply the brakes while driving, we are employing the benefits of deceleration to lower the speed of the car.

When we sense ourselves going forward in relation to the car while driving, we are decelerating. Deceleration in this context is a specific case of acceleration that only applies to moving things. It is hence the speed at which an object slows down.

Which choice tells the main causes of convection currents in the asthenosphere? question 5 options: density and temperature temperature and pressure density and weight weight and pressure

Answers

The main causes of convection currents in the asthenosphere are density and temperature.

Convection currents move heat from one location to another by utilizing the mass motion of a fluid such as water, air, or molten rock. Convection differs from conduction. Convection is process of transferring heat through the bulk movement of molecules in fluids such as gases and liquids.Convection currents are formed when a heated fluid expands and becomes less dense. The less dense heated fluid rises away from the source of heat. It pulls cooler fluid down to replace it as it rises. This hot fluid rises and pushes down more cool fluid. This cycle creates a circular circulation that only ends when heat is dispersed equally throughout the fluid.

B) You should deflect the ball

two balls a and b, having different but unknown masses, collide. a is initially at rest when b has a speed v. after collision, b has a speed of v/2 and moves at a right angle to its original motion. find the direction in which the ball a moves after the collision.

Answers

If A ball is at rest, the moving ball's velocity vector must point to the center of the stationary ball.

Explain about the velocity vector?

A velocity vector shows the rate of change in an object's position. The magnitude of a velocity vector represents an object's speed, whereas the vector's direction represents an object's direction. Velocity vectors can be added or removed in accordance with the principles of vector addition. the velocity vectors' length.

If we just state that a car is moving at 70 km/h, we have not fully described its motion because we have not stated the direction in which it is moving. Thus, a vector quantity such as velocity is an example.

Protons carry ___ compared to electrons.
A) an equal magnitude of charge
B) more magnitude of charge
C) less magnitude of charge
Pick ONE only.

Answers

Answer:

Explanation:

Protons carry   an equal magnitude of charge compared to electrons.

A) an equal magnitude of charge

Protons carry an equal magnitude of charge compared to electrons. Thus, option A is correct.

A proton is a stable subatomic particle occurring in all atomic nuclei, with a positive electric charge equal in magnitude to that of an electron, but of the opposite sign.

An electron is a stable subatomic particle with a negative electric charge, found in all atoms, and acts as the primary carrier of electricity in solids.

Although the mass of a proton is much larger than that of an electron, the magnitudes of their charges are equal.

How can I figure out the area of something in physics?

Answers

Area in physics can be found by division of the area into simple figures such as triangles, rectangles and trapezoids and offsets from a straight line.

How to find area in physics?

Area is a measure of how much space is there inside a shape and calculating the area of a shape or surface can be useful in everyday life.

The amount of surface a two-dimensional shape can cover which is measured in square units is called area and the SI unit of area is the square meter.

Area = length x breadth and  Area = π × radius × radius - formulas can be used for finding area of different quadrilaterals.

Serena travels 1100m in 26.2s. How many significant digits should be in your answer?

Answers

The speed of Serena in the correct number of significant  figures is  43.00 m/s

What is the speed?

The term speed is defined as the ratio of the distance to the time that is taken. Let us recall that speed is a vector quantity hence we do not need to use the direction in finding the speed at all.

We now have the following;

Distance travelled =  1100m

Time taken = 26.2s

Speed of Serena = 1100m/26.2s

= 42.98 m/s

The speed of Serena to the correct number of significant figures is 43.00 m/s.

three objects are at the top of an inclined plane: a disk, a sphere, and a ring. all of the objects have the same radius and the same mass. which object would finish last in a race down the incline if they are all released from rest? (hint: use conservation of energy methods, and note that at the bottom there is both translational and rotational energy)

Answers

The ring would finish at last in the race down the incline.

Incline is a a plane surface tilted at some angle from the horizontal.

The moment of inertia of the ring = [tex]mr^{2}[/tex]

The moment of inertia of the disc = ( [tex]mr^{2}[/tex] ) / 2

The moment of inertia of the solid sphere = 2( [tex]mr^{2}[/tex] ) / 5

Since the moment of inertia is the resistance to rotational motion, we see that the object with the smallest moment of inertia will reach the bottom first.

The gain in total kinetic energy is equal to the loss in gravitational potential energy, which in turn is the same for all the objects and is equal to 'mgh'

where h is the height of the inclined plane.

So the order of reaching the bottom is Sphere, disc and ring.
