Using the midpoint and the distance formulas, calculate he coordinate of the midpoint and the length of the segment.

arsen [322]

Answer:

Explanation:

Formula to calculate the distance between two points $(x_1,y_1)$ and $(x_2,y_2)$ is,

d = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Therefore, length of CD having coordinates C(3,1) and D(3, 3),

CD = $\sqrt{(3-3)^2+(1-3)^2}$

= 2 units

Formula to find the midpoint of CD is,

M = $(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})$

= $(\frac{3+3}{2},\frac{1+3}{2})$

= (3, 2)

Therefore, length of CD = 2 units and (3, 2) are the coordinates of the midpoint of CD.

A large vessel of the diameter of 14 mm divides into two identical smaller vessels but the velocity of blood in

ycow [4]

Answer:

the diameter of the smaller vessels is 9.90 mm

Explanation:

The computation of the diameter of the smaller vessels is given below;

Given that

The larger vessel of the diameter is 14mm

So,

d1 = 7 mm

let us assume the diameter of the smaller artery is d2

Now we used the equation of continuity i.e.

v × pi × d1^2 = 2 × v × pi × d2^2

14^2 = 2 × d2^2

d2 = 9.90 mm

Hence, the diameter of the smaller vessels is 9.90 mm

A child bounces a 51 g superball on the sidewalk. The velocity change of the super bowl is from 22 m/s downward to 14 m/s upward

noname [10]

Answer:

$F=1.02x10^{-3} N$

Explanation:

From the exercise we know:

$m=51g*\frac{1kg}{1000g}=0.051kg$

$v_{1}=-22m/s$

$v_{2}=14m/s$

$t_{2}-t_{1}=1800s$

So, the average acceleration is:

$a=\frac{v_{2}-v_{1}}{t_{2}-t_{1}}=\frac{(14-(-22))m/s}{1800s}=0.02m/s^2$

The average force is:

$F=m*a=(0.051kg)(0.02m/s^2)=1.02x10^{-3} N$

If a train going 60 m/s hits the brakes, and it takes the train 85 seconds to stop, what is

Anvisha [2.4K]

Question :-

If a Train going with 60 m/s Speed hits the Brakes, and takes 85 sec to stop. What is the Acceleration of the Train ?

Answer :-

Acceleration of Train is 0.70 m/s² .

Explanation :-

As per the provided information in the given question, we have been given that the Speed of the Train is 60 m/s . Time taken to stop the Train is 85 sec . And, we have been asked to calculate the Acceleration of the Train .

For calculating the Acceleration , we will use the Formula :-

$\bigstar \: \: \: \boxed { \sf{ \: Acceleration \: = \: \dfrac{v \: - \: u}{t} \: }} \\$

Where ,

V denotes to Final Velocity .
U denotes to Initial Velocity .
T denotes to Time Taken .

Therefore , by Substituting the given values in the above Formula :-

$\dag \: \: \: \: \sf{Acceleration \: = \: \dfrac{Final \: Velocity \: - \: Initial \: Velocity}{Time} } \\$

$\longmapsto \: \: \: \sf{Acceleration \: = \: \dfrac{0 \: - \: 60}{85} } \\$

$\longmapsto \: \: \: \sf{Acceleration \: = \: \dfrac{60}{85} } \\$

$\longmapsto \: \: \: \textbf {\textsf {Acceleration \: = \: 0.70 }}$

Hence :-

Acceleration = 0.70 m/s² .
