5. From the definition of work, explain why only the vertical height of the stairs is measured. Hint: Think of the data table co
natulia [17]
The motivation behind why the vertical stature of the stairs is the main thing measured is that it uncovers to us how much gravity is up against the individual and their weight, so we require this data to decide how much vitality and power we have to get up the stairs.

This is Yolanda's desk. What could Yolanda do to increase the amount of force needed to change the motion of the desk?
Stella [2.4K]

Yolanda might put more items to the desk to make it heavier, requiring more force.

We need to learn more about the force acting on an object in order to locate the solution.

<h3>How can the force that is required to modify the motion be increased?</h3>
  • We are aware that the word for force is,

                            F=ma

where m denotes the object's mass and an its acceleration

  • There are two ways to increase the force required to alter the motion of the table.
  • One is to increase the mass, and the other is to accelerate it more quickly.
  • Otherwise, there will be a lot of friction between the surfaces, making it difficult to move without exerting a lot of force.

We can infer from this that Yolanda could add items to the desk to increase its mass, necessitating the use of additional force.

Pressure is about 1000 hPa at sea level and about 500 hPa at an altitude of 5.5 km. Why doesn’t this vertical pressure gradient
saul85 [17]

Answer:

A. The upward pressure gradient force is balanced by gravity.

Explanation:

A. is correct because the pressure difference is actually generated by gravity. As in the following formula for the pressure at different points:

p = p_0 + \rho g h

where p, p_0 are the pressure at 2 points, ρ is the density of the fluid, g is the gravitational constant, and h is the height difference.

B is incorrect because friction in air is too small to make an effect.

C is incorrect because the Coriolis force is horizontal, not vertical.

D is incorrect because a difference of 500 hPa = 50000 Pa, this is half of the atmospheric pressure.

E is incorrect because temperature cannot generate force.

What is the value of x in the equation Ix - 3y = 30, when y = 15?
ankoles [38]

Answer: x= 75

Explanation:1x -3y = 30

And y = 15

Substitute y accordingly into the equation, so that

x - 3(15) = 30

x-45=30

Add 45 to both sides if the equation

x-45+45=30+45

x=75
