True or false the hotter the star the higher is absolute magnitude?

a force of 35N is exerted over a cylinder with an area of 5m^2. What pressure,in pascals, will be transmitted in the hydraulic s

gayaneshka [121]

Answer:

<h3>The answer is 7 Pa</h3>

Explanation:

The pressure transmitted in the hydraulic system can be found by using the formula

$p = \frac{f}{a} \\$

f is the force

a is the area

From the question we have

$p = \frac{35}{5} \\$

We have the final answer as

Hope this helps you

An object moves from position +34m to the position -15m in 15 seconds. What is the total displacement? What is the total velocit

Alexandra [31]

1) Displacement: -49 m, in the negative direction

Explanation:

The displacement of an object is a vector, whose magnitude is given by the difference between the final point of the motion and the starting point:

$d=p_f -p_i$

In this problem, the starting point is +34 m, while the final position is -15 m; therefore, the displacement is:

$d=-15 m- (+34 m)=-49 m$

and the direction is negative, in according to the negative sign.

2) Velocity: -3.27 m/s

Explanation:

Velocity is equal to the ratio between the displacement and the time taken:

$v=\frac{d}{t}$

in this problem, we have:

d = -49 m is the displacement

t = 15 s is the time

therefore, the velocity is

$v=\frac{-49 m}{15 s}=-3.27 m/s$

and the direction is negative.

Bare free charges do not remain stationary when close together. To illustrate this, calculate the acceleration of two isolated p

Marta_Voda [28]

Answer:

Acceleration, $a=9.91\times 10^{15}\ m/s^2$

Explanation:

It is given that,

Separation between the protons, $r=3.73\ nm=3.73\times 10^{-9}\ m$

Charge on protons, $q=1.6\times 10^{-19}\ C$

Mass of protons, $m=1.67\times 10^{-27}\ kg$

We need to find the acceleration of two isolated protons. It can be calculated by equating electric force between protons and force due to motion as :

$ma=\dfrac{kq^2}{r^2}$

$a=\dfrac{kq^2}{mr^2}$

$a=\dfrac{9\times 10^9\times (1.6\times 10^{-19})^2}{1.67\times 10^{-27}\times (3.73\times 10^{-9})^2}$

$a=9.91\times 10^{15}\ m/s^2$

So, the acceleration of two isolated protons is $9.91\times 10^{15}\ m/s^2$ . Hence, this is the required solution.
