1). <u>Potential energy</u> = (mass) x (gravity) x <em>(HEIGHT) </em>

2). <u>Kinetic energy</u> = (1/2) x (mass) x<em> (SPEED)²</em>

In a science lab, Thomas used "universal indicator" to investigate the pH of some household products. He created a reference tab
dolphi86 [110]

Usually

pH scale measures from 1 to 14

Purple colour indicates pH as 14

Hence it's an base

But it doesn't react with metals to form salts and hydrogen gas.

It's sure it's non metal but not base

One possibility is that it's Carbon compound or Graphite compound which reacts like base but a metal in real sometimes

A car with a mass of 800 kg, moving at +15 m/s, crashes head on with a 1500 kg truck moving at -45.5 m/s in the opposite directi
Sloan [31]

Answer:

v = -24.5 m/s

Explanation:

Use conservation of momentum P = m*v. Unless there are external forces involved, total momentum must be conserved.

P: momentum

m: mass

v: velocity

1. calculate the total momentum before the collision:

P=m_{car}v_{car} + m_{truck}v_{truck}

2. the total momentum after the collision must not change:

P_{before}=P_{after}

3. after the collision the velocity of the car is the same as the velocity of the truck:

v = v_{car} = v_{truck}

4. combining 2. and 3.:

P= (m_{car}+m_{truck})v

5. this equation only has one unknown and can be solved for v:

v = \frac{P}{m_{car}+m_{truck}} =\frac{m_{car}v_{car} + m_{truck}v_{truck}}{m_{car}+m_{truck}}

v=\frac{800*15 + 1500 * (-45.5)}{800 + 1500} = -24.5
