Particle A of charge 3.06 10-4 C is at the origin, particle B of charge -5.70 10-4 C is at (4.00 m, 0), and particle C of charge
Alex

Answer:

F_net = 26.512 N

Explanation:

Given:

Q_a = 3.06 * 10^(-4 ) C

Q_b = -5.7 * 10^(-4 ) C

Q_c = 1.08 * 10^(-4 ) C

R_ac = 3 m

R_bc = sqrt (3^2 + 4^2) = 5m

k = 8.99 * 10^9

Coulomb's Law:

F_i = k * Q_i * Q_j / R_ij^2

Compute F_ac and F_bc :

F_ac = k * Q_a * Q_c / R^2_ac

F_ac =  8.99 * 10^9* ( 3.06 * 10^(-4 ))* (1.08 * 10^(-4 )) / 3^2

F_ac = 33.01128 N

F_bc = k * Q_b * Q_c / R^2_bc

F_bc =  8.99 * 10^9* ( 5.7 * 10^(-4 ))* (1.08 * 10^(-4 )) / 5^2  

F_bc = - 22.137 N

Angle a is subtended between F_bc and y axis @ C

cos(a) = 3 / 5

sin (a) = 4 / 5

Compute F_net:

F_net = sqrt (F_x ^2 + F_y ^2)

F_x = sum of forces in x direction:

F_x = F_bc*sin(a) = 22.137*(4/5) = 17.71 N

F_y = sum of forces in y direction:

F_y = - F_bc*cos(a) + F_ac = - 22.137*(3/5) + 33.01128 = 19.72908 N

F_net = sqrt (17.71 ^2 + 19.72908 ^2) = 26.5119 N

Answer: F_net = 26.512 N

What type of image is formed by a lens if m = -1.6?
anastassius [24]

The image formed from the lens is real, inverted and enlarged

Explanation:

The magnification of a lens is given by:

m=\frac{y'}{y}=-\frac{q}{p} (1)

where:

y' is the size of the image

y is the size of the object

q is the distance of the image from the lens

p is the distance of the object from the lens

For this lens, the magnification is

m = -1.6

We notice the following:

- The magnification is negative

- The magnification is larger than 1

Looking at eq.(1), we can therefore make the following conclusions:

- SInce m=\frac{y'}{y} and |m|>1, it follows that |y'|>|y|, so the image is larger than the object

- Since m=\frac{y'}{y} and m, it follows that y' (since y > 0 for convention): this means that the image is inverted

- Since m=-\frac{q}{p} and m, it follows that q>0 (since p > 0 for convention): this means that the image is real

Khalil is driving laps at a racetrack. The track is circular and has a radius of 25 m. After
zysi [14]

The difference between the distance and the displacement is the speed is a scalar while displacement is a vector.

<h3>What is the distance an the displacement?</h3>

The distance is the difference between two points while the displacement is the difference between two points in a specified direction. Given that speed is a scalar and the displacement is a vector. It follows that we must take the displacement when obtaining the displacement.

Thus, the distance that is covered after one lap is  the circumference of the circle = 2πr = 2 * 3.142 * 25 = 31 m Then for 2 laps = 62 m

The displacement is obtained when we take the direction into consideration. Owing to the fact that the runner returns to the starting point each time, the displacement is zero.

When cells get ready to divide, they need to grow several different structures. What do all cells need in order to grow these st
rodikova [14]

Answer:

To survive, every cell must have a constant supply of vital substances such as sugar, minerals, and oxygen, and dispose of waste products, all carried back and forth by the blood cells. Without these substances, cells would die in a very short period of time.
