An electron moving along the x axis has an initial speed of 1 × 106 m/s at the origin. Its speed is reduced to 5 × 105 m/s at th

mina [271]

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

Which of the outer planets is MOST like Earth? How?

Over [174]

Answer:

It is not impossible to answer the question, my apologies for “discrediting” the answer it would have to be Venus, the outer planet most similar to earth.

Explanation:

Venus is very similar to earth, as many studies, research, factual intellectual based concepts - the size, shape, surface gravity, average density, mass, average days of 24 hours, season changes similar to earth, and tilted axis. As well as similar climate make Venus the most accurate answer.

Hope this helps! Thank you for your time.

A mechanic pushes a 2.60 ✕ 103-kg car from rest to a speed of v, doing 5,430 J of work in the process. During this time, the car

Oduvanchick [21]

Part A. We are given that a car is pushed from rest to a final speed doing 5430 Joules of work. -

To determine the final velocity we will use the work and energy theorem which states that the work done is equal to the change in kinetic energy:

$W=K_f-K_0$

Since the car starts from rest this means that the initial kinetic energy is zero:

$W=K_f$

The kinetic energy is given by:

$K=\frac{1}{2}mv^2$

Substituting in the formula we get:

$W=\frac{1}{2}mv_f^2$

Now, we solve for the final velocity. First, we multiply both sides by 2 and divide both sides by the mass:

$\frac{2W}{m}=v_f^2$

Now, we take the square root to both sides:

$\sqrt{\frac{2W}{m}}=v_f$

Now, we plug in the values:

$\sqrt{\frac{2(5430J)}{2.6\times10^3kg}}=v_f$

Solving the operations:

$2.04\frac{m}{s}=v_f$

Therefore, the final velocity is 2.04 m/s.

Part B. Now, we use the following formula for work:

$W=Fd$

Where "F" is the force and "d" is the distance.

Now, we set this equation equal to the work done by the force:

$Fd=5430J$

Now, we divide both sides by the distance "d":

$F=\frac{5430J}{29m}=187.2N$

Therefore, the force exerted is 187.2 Newton.

An electrician is creating a wiring plan for a small house. He needs to create a plan that will allow the homeowners to turn off

Helga [31]

Answer:

Option B

Wire each room in parallel with the next.

Explanation:

By having parallel circuit, it creates more than one path for energy source. That means that even if one route has been closed by one neighbour, the energy source can get another path. One advantage of parallel connection is that even if one load goes out, the rest of the bulbs within the circuit are not affected. For parallel circuit, voltage remains constant every time a new load is added or removed since each load has its own path to the energy source and will receive full voltage. Therefore, the electrician should wire each room in parallel with the next.
