Hooke's law states that the force, F, in a spring extended by a length x is given by

timofeeve [1]

Answer:

dimensions of k are kg / s^2

Explanation:

F=ma (Newton's second law)

F=-kx (Hooke's law)

so equate both

-kx = ma

k = -ma/x

= mass * acceleration / distance (dimensions, -1 has no dimension)

= kg * m/s^2 / m

= kg / s^2

physics A river flows at a speed vr = 5.37 km/hr with respect to the shoreline. A boat needs to go perpendicular to the shorelin

vova2212 [387]

Answer: Vb is the vector (-5.37m/s, 8.59 m/s), with a module 10.13m/s

then the ratio Vb/Vr = 10.13m/s/5.37m/s = 1.9

Explanation:

We can use the notation (x, y) where the river flows in the x-axis and the pier is on the y-axis.

We have Vr = (5.37m/s, 0m/s)

Now, if the boat wants to move only along the y-axis (perpendicularly to the shore).

The velocity of the boat Vb will be:

Vb = (-c*sin(32). c*cos(32))

Then we should have that:

5.37 m/s - c*sin(32) = 0

c = (5.37/sin(32))m/s = 10.13 m/s

the velocity in the y-axis is:

10.13m/s*cos(32) = 8.59 m/s

So Vb = (-5.37m/s, 8.59 m/s)

the ratio Vb/Vr = 10.13m/s/5.37m/s = 1.9 where i used Vb as the module of the boat's velocity.

A gnat takes off from one end of a pencil and flies around erratically for 41.641.6 s before landing on the other end of the sam

wlad13 [49]

Answer:

average speed is 0.159 m/s

average velocity = 0.0011 m/s

Explanation:

given data

time = 41.6 s

total distance = 6.65 m

length = 0.0463 m

to find out

average speed and the magnitude average velocity

solution

we know average speed formula is

average speed = $\frac{total distance}{total time}$ ...............1

put here value

average speed = $\frac{6.65}{41.6}$

average speed is 0.159 m/s

and

average velocity formula is

average velocity = $\frac{displacement}{total time}$ ...............2

here displacement is initial point to final point and here is 0.0463 m

put here value

average velocity = $\frac{0.0463}{41.6}$

average velocity = 0.0011 m/s

A can of soft drink at room temperature is put into a refrigerator so that it will cool. The can of soft drink should be analyze

tamaranim1 [39]

Answer:

Closed

Explanation:

Metal is a good conductor of electricity and heat.

In electricity terms, electricity will work in the closed circuits so only close loops will work.

In open circuits there is no flow of electricity because of no continuous loop.

If the cooling of the can is taken place, then the heat is flowing out of the can into the fridge while cool air from the fridge is flowing into the can form a loop.

Therefore, the can of the soft drink is a closed system.
