It goes around the x axis
Answer:
Final velocity is 181.61 m/s at angle 40.44° below horizontal.
Explanation:
Initial horizontal velocity = 170 cos 35.6 = 138.23 m/s
Final horizontal velocity = 138.23 m/s
Considering vertical motion of projectile:
Initial vertical velocity, u = 170 sin 35.6 = 98.96 m/s
Acceleration, a = -9.81 m/s²
Displacement, s = -208 m
We have v² = u² + 2as
Substituting
v² = 98.96² + 2 x -9.81 x -208
v = 117.79 m/s
Final velocity,


Final velocity is 181.61 m/s at angle 40.44° below horizontal.
Answer:
KE = 250 kg/m/s
Explanation:
use the formula: KE = 1/2 m (v^2)
KE = 1/2 (5) (10^2)
KE = (2.5) (100)
KE = 250 kg/m/s
The relationship between the voltage and the current in the circuit is:

where

is the voltage difference, R the resistance of the circuit (and therefore, the resistance of the battery) and I the current flowing in the circuit. By using I=19 A and

, we can find the internal resistance of the battery:
In this equation
1 Cl2 + 3 F2---> 2 ClxFy
those coefficients are in MOLE (or molecule) ratios. BUT for gases at the same temp and pressure, they are also VOLUME ratios.. why? PV = nRT, V = nRT/P. if RT/P = constant.. V1/n1 = V2/n2 --> n1/n2 = V1/V2..make sense? mole ratios
= volume ratios
so.. what are x and y?
1 Cl2 + 3 F2---> 2 ClxFy
2 Cl's on the left.. x must = 1
6 F2's on the left. y must be 3
1 Cl2 + 3 F2---> 2 ClF3
