You’re going to use the formulae, mgh( mass x gravity on Earth x height). In your question the answer is gonna be like this:
GPE= mgh= 25x10x3= 38 J

Answer:

3.9 m/s

Explanation:

We are given that

Mass of car,m= $2.1\times 10^3 kg$

Initial velocity,u=0

Distance,s=5.9 m

$\theta=19^{\circ}$

Average friction force,f= $4.0\times 10^3 N$

We have to find the speed of the car at the bottom of the driveway.

Net force, $F_{net}=mgsin\theta-f=2.1\times 10^3\times 9.8sin19-4.0\times 10^3$

Where $g=9.8 m/s^2$

Acceleration, $a=\frac{F_{net}}{m}=\frac{2.1\times 10^3\times 9.8sin19-4.0\times 10^3}{2.1\times 10^3}$

$v=\sqrt{2as}$

$v=\sqrt{2\times \frac{2.1\times 10^3\times 9.8sin19-4.0\times 10^3}{2.1\times 10^3}\times 5.9}$

v=3.9 m/s

Molecular chlorine and molecular fluorine combine to form a gaseous product. Under the same conditions of temperature and pressu

kotegsom [21]

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 <span>
