Answer:
The answer is:-
Explanation:
An electron emitted from an atom by enteraction with an photon, especially an eclectron emitted from a solid surface by the action of light.
Answer:
P=1113.35 psi
Explanation:
For tank 1
V₁= 6.25 L
P₁=1759 psi
For tank 2
V₂=6.25 L
P₂=467.7 psi
Lets take final pressure is P
The final volume V= 6.25 + 6.25 L = 12.5 L
P V = V₂P₂+V₁P₁
Now by putting the values
P V = V₂P₂+V₁P₁
P x 12.5 = 6.25 x 467.7+6.25 x 1759
P=1113.35 psi
So the final volume of the system will be 1113.35 psi.
t1 = √2h1/g = √2*0.5/9,8 = 0.319 sec
t2 = √2h2/g = √2*1.0/9,8 = 0.451 sec
In which t = times for the vertical movement
h = height
g= gravity (we use standardized measurement of 9.8)
d1 = 1*0.319 = 0.319 m
d2 = 0.5*0.451 = 0.225 m
in which d = Horizontal distance
ratio
= di : d2
= 0.319 : 0.225
= 3.19 : 2.25
Answer:
34.8 and 55.2º
Explanation:
This is a projectile launching exercise, as we are told that the range of the arrow must be equal to its range and = 31 m let's use the equation
The scope equation is
R = v₀² sin 2θ /g
sin 2 θ = R g / v₀²
sin 2 θ = 31 9.8 / 18²
2 θ = sin⁻¹ 0.93765
θ = 34.8º
At the launch of projectiles we have two complementary angles with the same range in this case 34.8 and (90-34.8) = 55.2º
