briefly discuss university need based scholarships and explain them.
Answer: Scholarships are given to reduce the burden of finance to be payed for academics and learning.
Explanation:
The need based scholarships are given in the following matters:
1. Research based scholarships: Scholarships should be given to meritorious students to conduct research in a particular discipline.
2. Student fails to submit fees: The student if meritorious and family is not able to fees then university can either postpone the date for fees payment or can give some concession in fees or fund the student fees for a tenure. It is a kind of scholarship for meritorious students.
3. Teacher scholarships: Teachers are allowed to learn new teaching methodologies with other institutions so that they can help students to learn well. They are provided with scholarships to avail admission in those institutions.

Answer:
An object in motion will remain in motion until it experiences an unbalanced force.
Explanation:
This is part of Newton's first law. An unbalanced force is there to offset the object in motion, such as a ball versus a wall. A wall will stop the ball from moving.
Why are the oceans movements along the What do ocean waves have in common with the sound and light
Answer:
Oceanic currents an waves are in motion due to energy of wind.
Explanation:
When the wind blows across the ocean water ts creates a pull and push effect. It pulls the top layers of water and creates a frictional drag force that leads to the movement of water molecules and appears that the surface is moving. The movement can be seen in the form of surface oceanic currents and waves that are found through the entire globe. The ocean waves and currents carry with them the energy from one place to another.

Explanation:
Xander reached a final velocity of 4.5 m/s for 3.5 seconds. Finley reached a final velocity of 3.6 m/s for 4.2 seconds. Max reached a final velocity of 7.3 m/s for 1.2 seconds. They all started at the same location from rest. Which lists them from least to most acceleration? Max Finley Xander Max Xander Finley Xander Finley Max Finley Xander Max
Answer:
Finley, Xander and Max
Explanation:
v = Final velocity
t = Time
u = Initial velocity = 0
a = Acceleration
From kinematic equations we get
[tex]v=u+at\\\Rightarrow a=\dfrac{v-u}{t}=\dfrac{v-0}{t}\\\Rightarrow a=\dfrac{v}{t}[/tex]
Xander
v = 4.5 m/s, t = 3.5 s
[tex]a=\dfrac{4.5}{3.5}\\\Rightarrow a=1.29\ \text{m/s}^2[/tex]
Finley
v = 3.6 m/s, t = 4.2 s
[tex]a=\dfrac{3.6}{4.2}\\\Rightarrow a=0.86\ \text{m/s}^2[/tex]
Max
v = 7.3 m/s, t = 1.2 s
[tex]a=\dfrac{7.3}{1.2}\\\Rightarrow a=6.083\ \text{m/s}^2[/tex]
The required list is Finley, Xander and Max.

What causes the pressure in a fluid
Answer:
The pressure in a liquid is due to the weight of the column of water above. Since the particles in a liquid are tightly packed, this pressure acts in all directions. For example, the pressure acting on a dam at the bottom of a reservoir is greater than the pressure acting near the top.
Answer:
Fluid pressure can be caused by gravity, acceleration, or forces in a closed container. Since a fluid has no definite shape, its pressure applies in all directions.

Why is the sky blue? The earth is surrounded by an atmosphere.
Answer:
The blue component of the spectrum of visible light has shorter wavelengths and higher frequencies than the red component. Thus, as sunlight of all colors passes through air, the blue part causes charged particles to oscillate faster than does the red part. The faster the oscillation, the more scattered light is produced, so blue is scattered more strongly than red. For particles such as air molecules that are much smaller than the wavelengths of visible light the difference is dramatic. The acceleration of the charged particles is proportional to the square of the frequency, and the intensity of scattered light is proportional to the square of this acceleration. Scattered light intensity is therefore proportional to the fourth power of frequency. The result is that blue light is scattered into other directions almost 10 times as efficiently as red light.

what happens to the motion of objects when they hit each other?
Answer:
When two objects in motion hit each other they experience forces that are equal in magnitude and opposite in direction. This force causes one of the objects to speed up or gain momentum and other to slow down or lose momentum.

Answer:D. Watching the left-over dirt from a comet burn up by friction as the pieces hit the Earth's atmosphere
Explanation: A meteor shower is giant rocks moving across the sky
There must be an invitation for d. watching the left-over dirt from a comet burn up by friction as the pieces hit the Earth's atmosphere
What is a Meteor showers ?
Meteor showers occur when dust or particles from asteroids or comets enter Earth's atmosphere at very high speed. When they hit the atmosphere, meteors rub against air particles and create friction, heating the meteors. The heat vaporizes most meteors, creating what we call shooting stars
hence correct option will be D) Watching the left-over dirt from a comet burn up by friction as the pieces hit the Earth's atmosphere

What is the mass of a 50kg object in space with no gravity?
Answer:
The answer would be 0kg.
Your welcome.
1.Una partícula de masa m = 0.2 [kg] está unido a dos resortes idénticos (de longitud L = 1.2 [m]) sobre la parte superior de una mesa horizontal sin fricción. Los dos resortes tienen la misma constante elástica de K = 40 [N/m] y cada uno esta inicialmente en su posición de equilibrio (punto O). Si la partícula se hala una distancia d = 0.5 [m] hacia la derecha y después se suelta (ver figura), ¿cuál es la velocidad cuando pasa por el punto O (posición de equilibrio)?

10. The elevator in the new office building warns that it can safely lift 300 kg at one time. If John (850N), Betty (530N), Robert (740N), and Alice (610N) all get in the elevator at once, can the elevator safely carry them up to the third floor?
I can't tell right away. The elevator's limit is given in terms of mass, but the four people are listed in terms of their weights. In order to compare them, we'll have to convert one or the other.
The total of the four people's weights is:
John . . . . . . . 850N
Betty . . . . . . . 530N
Robert . . . . . . 740N
Alice . . . . . . . .610N
Total . . . . . . 2,730N
The elevator can't accept more than 300 kg of mass.
The weight of any mass is (mass) x (gravity).
On Earth, 300kg weighs (300kg) x (9.8 m/s²) = 2,940 N.
Wonderful !
2,730N is less than 2,940N.
Yes ! According to Otis' engineers, John, Betty, Robert and Alice can safely ride the elevator together, (although Betty and Alice may have a different opinion).

Una muestra de agua de 250g de agua se caliento desde 10°C hasta 60°C calcula la cantidad de calor absorbido por el agua el calor especifico del agua es de 4186J/Kj.K
Answer:
Calor absorbido, Q = 52325 Joules
Explanation:
Dados los siguientes datos;
Masa = 250g to kg = 250/1000 = 0.25kg
Temperatura inicial, T1 = 10°C to Kelvin = 273 + 10 = 283K
Temperatura final, T2 = 60°C to Kelvin = 273 + 60 = 333K
Capacidad calorífica específica = 4186 j/kg.K.
Para encontrar la cantidad de calor necesaria;
La capacidad calorífica viene dada por la fórmula;
[tex] Q = mct [/tex]
Dónde;
Q representa la capacidad calorífica o la cantidad de calor.
m representa la masa de un objeto.
c representa la capacidad calorífica específica del agua.
dt representa el cambio de temperatura.
dt = T2 - T1
dt = 333 - 283
dt = 50 K
Sustituyendo en la fórmula, tenemos;
[tex] Q = 0.25*4186*50[/tex]
[tex] Q = 52325 [/tex]
Calor absorbido, Q = 52325 Joules

What can astronomical objects that have changing magnetic fields do
Answer:
During an excursion or a reversal, the magnetic field is considerably weakened and allows many more cosmic rays to reach the surface of the planet. These energetic particles from space can be damaging to life on Earth if too many reach the surface.
Explanation:
Radio waves may generate astronomical bodies with fluctuating magnetic fields. A further explanation is below.
Electrical charges nanoparticles, as well as molecules, moved via the circular or spiraling route of the magnetic fields. Somewhat on windsurfing spacecraft, various radio astronomy or communications tools named WAVES documented as well as captured a day of explosions of something like the Sun's chromosphere as well as the electromagnetic radiation of our observable universe.
