So for a minute lets ignore the 880 km/h. If it took 4 hours and she flew at 600 km/h 600*4=2400. Now lets Look at the 880 bit. If it took 4 hours and she where to fly at 880 it would've been 880*4=3520. Lets do 2400-600=1800, now we've got the 600 kmh bit done. Now lets see if you fly 880 km/h for one hour then you add 1800+880=2680.

Answer:
x = 1, y = 1 and z = 0
Explanation:
Given equation;
Boyle's law states that at constant temperature, the volume of a fixed mass of gas is inversely proportional to its pressure.
Mathematically the law is written as;
From the given equation, the values of x, y and z that will match this law is calculated as follows;
Answer:
The velocity after 2 seconds can be found through:
V = u +a*t
Where V is final velocity, u is initial velocity, a is acceleration and t is time.
V = 0 + 2* 2= 4 meters/second
The distance (s) can be found through:
V^2= u^2 +2*a* s
Where V is final velocity, u is initial velocity, a is acceleration.
4^2= 0^2 + 2 *2*s
16= 0 + 4s
s= 4 meters
Distance (s) can also be found through:
s= ut + 1/2 at^2
s= 0+ 1/2 *2*2^2= 1 *2*2
s= 4 meters
Explanation:
Answer:
Part a)
Part b)
Explanation:
Part a)
Electric field due to large sheet is given as
now the electric field is given as
Now acceleration of an electron due to this electric field is given as
Now work done on the electron due to this electric field
So work done is given as
Part b)
Now we know that work done by all forces = change in kinetic energy of the electron
so we will have
The unit is light years or Ly
