Answer:
32.71 L
Explanation:
We can solve this question using Boyle's law of ideal gas. The law states that the volume and pressure are inversely proportional when the temperature is constant. At first, the volume is 18L (V1) and the pressure is 87.6 kPa(P1). Then the pressure changed into 48.2 kPa(P2). We are asked to find the volume(V2).
The calculation will be:
P1 * V1= P2 * V2
87.6 kPa *18L = 48.2 kPa * V2
V2= 87.6 kPa *18L / 48.2 kPa
V2=32.71 L
Answer:
v = 70 m/s
Explanation:
Range on the cannon ball is given as
here the angle of the projection of the ball is given as 45 degree
now we know that if the velocity of the ball is "v" then its two components will be given as
so here time of flight of the motion is given as
also the range is given as
now plug in all data in this equation
Answer:
ik u got it bc this was 2 weeks ago
Explanation:
but yes and yuea
Electrons have a negative charge, so if you give away electrons, you give away negative charge, thus ending with a positive charge.
