For the ball to hit the ground it will take 4 seconds since 120 divided by 60 is 2 two times two=4

If a builder of mass 75kg climbs a vertical ladder of 25m how much energy has she gained ?

erica [24]

So,

GPE (graviational potential energy) = mass x g x height

GPE is depends on where zero height is defined. In this situation, we define h = 0 as the initial height.

$GPE = 75 \ kg*9.8 \ \frac{m}{s^2}*25 \ m$

$GPE = 18,375 \frac{kg*m^2}{s^2}$

$GPE = 18,375 \ joules(J) \ or \ 18.375 \ kilojoules(kJ)$

The builder has gained 18.375 kJ of PE.

How many electrons does it take to make up 4.33 C of charge?

Dovator [93]

Answer:

Number of electrons, $n=2.7\times 10^{19}$

Explanation:

It is given that,

Charge, q = 4.33 C

We need to find the number of electrons that make 4.33 C of charge. According to quantization of charge as :

$q=ne$

n = number of electrons

e = electron's charge

$n=\dfrac{q}{e}$

$n=\dfrac{4.33\ C}{1.6\times 10^{-19}\ C}$

$n=2.7\times 10^{19}$

So, the number of electrons are $2.7\times 10^{19}$ Hence, this is the required solution.

A reaction mixture in a 3.67 L flask at a certain temperature initially contains 0.763 g H2 and 96.9 g I2, At equilibrium, the f

Alexxandr [17]

Answer:

13 530 482

Explanation:

H2 + I2 ------> 2HI

start (mol) 0.3785 0.3818 0

change (mol) -0.3534 -0.3534 +0.7067

equilibrium (mol) 0.0251 0.0284 0.7067

concentra (mol/L) 0.0068 0.0077 0.1926

$K_{c} = \frac{0.1926^{2}}{0.0068^{2}*0.0077^{2} } = 13530482$
