You just have to simpy add the vectors together.  Draw a picture to help you.  Your verticle run is a vector that has a magntiude of 22m along the x axis with an angle of 0, and your climb has is a vector with a magnitude of 4.8 along the y axis and an angle of 90 degreed with respect to the x axis therefore add all of the x components and y components.  you will find that the resultant vector has a xcomponent of 22m and a y component of 4.8m so draw a graph the point will be (22,4.8) and then you can simply measure the angle.

It's going to be the angle whose tangent is (4.8 / 22).  That's about 0.2182, and you can easily use your calculator to find the angle that has that tangent.

a merry go round has a radius of 8 meters makes 2 revolutions every 2.5 minutes. A. express the angular speed of the merry go ar
pantera1 [17]

Answer:

a).v=83.77x10^{-3} rad/s

b).v=0.8rpm

c).v=0.5865 m/sec.

Explanation:

Given:

r=8m

v=\frac{2rev}{2.5minutes}

a).

2 rev*\frac{2\pirad}{1rev}=4\pi  rad

t=2.5minutes*\frac{60s}{1minute}=150s

The angular speed in radians per seconds is

v=\frac{4\pi}{150s}=83.77x10^{-3} rad/s

b).

v=\frac{2rev}{2.5minute}rpm

v=0.8rpm

c)

Child's distance per revolution

(pi*2r) = 43.988 metres.  

v=(43.988 x 0.0133333) = 0.5865 m/sec.

What will happen if the two plungers are pressed together firmly? Explain your answer.​
steposvetlana [31]

Answer:

This air being forced out causing the air pressure inside to be much lower than that on the outside. As higher air pressure always pushes, it keeps the two plungers together.

Hope that helps. x

What is the concentration of H+ ions at a pH = 2? mol/L What is the concentration of OH– ions at a pH = 2? mol/L What is the rat
densk [106]

Answer:

In Step 5, you will calculate H+/OH– ratios for more extreme pH solutions. Find the concentration of H+ ions to OH– ions listed in Table B of your Student Guide for a solution at a pH = 2. Then divide the H+ concentration by the OH– concentration. Record these concentrations and ratio in Table C.

What is the concentration of H+ ions at a pH = 2?

0.01   mol/L  

What is the concentration of OH– ions at a pH = 2?

0.000000000001   mol/L  

What is the ratio of H+ ions to OH– ions at a pH = 2?

10,000,000,000 : 1

I LITERALLY spent 40 MINUTES trying to figure out this question, so please, use my VERY CORRECT answers!

I hope this helps!

Weight is influenced by which of the following
nignag [31]

Out of the given options, weight is influenced by mass and gravity

Answer: Option A

<u>Explanation: </u>

The object's mass is defined as the quantity of a matter with which the object is formed. It can change its state of matter but the quantity will remain the same. However, the weight is defined as how much force gravity exerts on the object's mass to pull it.

The mass is always same irrespective the location but the weight may vary from one place to the other while talking for the bigger picture. For example, the object's weight may be 60 kg on Earth but when it is measured on the moon, it will be lesser.

The weight of an object generally has nothing doing with the volume and it doesn't depend solely on the gravitational pull. The mass plays a crucial role.

                                  W=F=m \times g
