What is the total electric flux due to these two point charges through a spherical surface centered at the origin and with radiu

alexira [117]

The expression for the flux through a sphere is
flux = charge/Enot (i.e. epsillon not: a constant)

this shows that flux doesn't vary with radius but with the charge of the points

The energy content of food is conventionally measured in Calories rather than joules. One Calorie in nutrition is equal to 4184

Rama09 [41]

Answer:

Part a)

$P = 186 W$

Part B)

$N = 676 times$

Explanation:

Part a)

Average power is rate of energy consumption

So it is given as

$P = \frac{mgh}{t}$

$P = \frac{100(75.7)(9.81)(0.150)}{59.9}$

$P = 186 W$

Part b)

If the efficiency is given as

$\eta = 20$ %

so we know that 20% of total energy consumed is converted into output work

So total power consumed here will be given as

$P = \frac{186}{0.20}$

$P = 930 W$

Energy consumed by him

$E = power \times time$

$E = 930 \times 59.9$

$E = 55707 J$

now we know that 1 g fat will release 9 Calories energy

So we have

$1 g = 9 \times 4184 J$

$1 g = 37656 J$

so to consume 1000 g of fat we need to release total energy

$E = 37656 \times 10^3 J$

so total number of times

$N = \frac{37656 \times 10^3}{55707}$

$N = 676 times$

Identify the statment below that could be an example of properly written long-term goal

Alex Ar [27]

Option (d)

Explanation:

The statement that could be an example of properly written long-term goal is Each week I am going to add .25 miles onto my run so i can reach a total of 5 miles by the end of this month.

It is corresponding to long term portrayed by the statement is, every week if the student is targeting for a goal and aims to complete 0.25 miles on his long run, by the end of the 4th week of the month, he would have achieved 5 miles of his long term target.

The strength of an electric field depends on the

KengaRu [80]

The correct option is D) both A and B. In fact, the strength of an electric field produced by a single point charge is given by
 $E=k \frac{Q}{r^2}$ 
where Q is the charge that generates the field, k is the Coulomb's constante and r is the distance from the charge source of the field.

From the equation, we see that the strength of the field depends on A) the amount of charge that produced the field (Q) and B) the distance from the charge (r), so the correct option is D.
