Kiley, Jermaine, and Gunther are playing tug-of-war. Kiley and Jermaine are on the same side of the rope, and Gunther is on the

other side. Kiley is exerting a force of 20 N, and Jermaine is exerting a force of 25 N.
Which force would result in a balanced force for the game?

-45N because you add the side together and make it equal 0

Kiley and Germaine pull together, resulting in a force of 45N which pulls the rope that way ===> .

In order to balance the forces on the rope, Gunther must pull the rope with a force of <em>45N this way  <===</em>, all by himself.

The net force on the rope will then be zero, and the rope will not accelerate.  (Although the tension inside the rope will be 90N.)

By the way . . . I'd love to see how the kids manage to all get on the "sides" of the rope.  I would have expected them to just do it the easy way and stand at the "ends" of the rope.

A cat with a mass of 5.00 kg pushes on a 25.0 kg desk with a force of 50.0N to jump off. What is the force on the desk?
olya-2409 [2.1K]

Answer:

First of all the formula is F= uR,( force= static friction× reaction)

mass= 5+25=30

F= 50

R= mg(30×10)=300

u= ?

F=UR

u= F/R

u= 50/300=0.17N

In a two-source circuit, one source acting alone produces 10 ma through a given branch. the other source acting alone produces 8
pashok25 [27]
Refer to the figure below.
R = resistance.

Case 1:
The voltage source is V₁ and the current is 10 mA. Therefore
V₁ = (10 mA)R

Case 2:
The voltage source is V₂ and the current is 8 mA. Therefore
V₂ = (8 mA)R

Case 3:
The voltage across the resistance is V₁ - V₂. Therefore the current I is given by
V₁ - V₂ = IR
10R - 8R = (I mA)R
2 = I
The current is 2 mA.

Answer: 2 mA

Antonina throws a coin straight up from a height of
vichka [17]

Answer:

s=vt-\frac{1}{2}gt^2

Explanation:

We could use the following suvat equation:

s=vt-\frac{1}{2}gt^2

where

s is the vertical displacement of the coin

v is its final velocity, when it hits the water

t is the time

g is the acceleration of gravity

Taking upward as positive direction, in this problem we have:

s = -1.2 m

g=-9.8 m/s^2

And the coin reaches the water when

t = 1.3 s

Substituting these data, we can find v:

v=\frac{s}{t}+\frac{1}{2}gt=-\frac{1.2}{1.3}+\frac{1}{2}(-9.8)(1.3)=-7.3 m/s

where the negative sign means the direction is downward.
