No Solution:
4x+10y = 40
2x + 5y = 40
2x - 8y=17
x - 4y = 7
One Solution:
2y - X= 12
2y - 2x =10
x + 10y =50
2x + 10y =90
Infinitely Many Solutions:
x + 2y = 1
3x + 6y= 3
2y - 3x = 5
2/5y -3/5x =1
Explanation: You only had 11 equations listed. But I believe these are the ones you want. I took the test and got them right. Hope it helps
Answer:
By the use of the reaction force one body is able to accelerate because it is not fixed to a rigid support which offers a materialistic resistance.
Explanation:
For every force there is an equal and opposite reaction is stated in the Newton's third law of motion holds true universally.
This law accounts for the acceleration of the bodies with respect to the object that applies force on the other body. The acceleration is possible when iether one of the body is fixed and cannot move or when that both the bodies are not fixed can move.
- For example consider a rocket with its engine started. This rocket generates upthrust by conversion of chemical energy of the fuel into the mechanical energy applying force on the launchpad. When this force is large enough it to lift the rocket then the rocket starts moving in the air and it accelerates. Now, when it is in the air or in vacuum during the course of its journey it uses the reaction of the burnt gases of the fuel to change the momentum.
This is in accordance with the Newton's second law of motion, stating that the Force is directly proportional to the rate of change in momentum.
Answer:
The velocity is 
Explanation:
From the question we are told that
The mass of the bullet is 
The initial speed of the bullet is 
The mass of the target is 
The initial velocity of target is 
The final velocity of the bullet is is 
Generally according to the law of momentum conservation we have that
=> 
=>
A white dwarf cannot support its own weight by its degenerate pressure if its mass is greater than 1.4 solar masses.
<h3>
What are white dwarfs?</h3>
White dwarfs are stellar core remnant composed mostly of electron-degenerate matter.
White dwarf is very dense due to its large mass and smaller volume.
<h3>Reasons for comparable mass of white dwarfs and Sun</h3>
- Stars with main sequence masses less than about 0.5 solar masses cannot ignite the helium fusion required to become white dwarfs.
- A white dwarf cannot support its own weight by its degenerate pressure if its mass is greater than 1.4 solar masses.
