Answer:

-2.13 V

Explanation:

Given parameters are:

$v_i = 1 * 10^6$ m/s

$v_f = 5 * 10^5$ m/s

$q = -e = 1.602 * 10^{-19}$ C

$m = 9.109 * 10^{-31}$ kg

By conservation of energy principle, we know that the potential difference between two points is equal to the change in the kinetic energy between these points.

$-\Delta U = \Delta KE\\\\-e\Delta V = \frac{1}{2} mv_f^2 - \frac{1}{2} mv_i^2$

Hence,

$1.602*10^{-19}\Delta V = \frac{1}{2}*9.11*10^{-31}((5*10^5)^2 - (1*10^6)^2)$

⇒ $\Delta V = -2.13$ V

You calculate that the maximum static friction is 420N. If you apply 500N of force, will the couch slide?

Valentin [98]

Assuming that the entirety of the force is opposite the static friction, then the couch should begin sliding as the applied force overcomes the couch's static friction with what it's making contact with.

Here is something to blow your mind. In one slice of "everything" pizza there are 650 Calories (1000 chemistry calories). That e

amid [387]

Answer:

Number of slices of pizza is 993.

Explanation:

It is given that, in one slice of "everything" pizza there are 650 Calories. The conversion factor from calories to joules is :

1 calorie = 4.184 joules

650 calories = 2719.6 joules

Total energy in the pizza, E = 2700000 J

Let there are n number of slices of pizza. It is given by :

$n=\dfrac{2700000}{2719.6}$

n = 992.79

n = 993

So, there are 993 slices of pizza. Hence, this is the required solution.
