Answer:

10 watts

Explanation:

first calculate work.

Work =force×distance cos thita

10Kg×0.50M cos 0= 5joules

Therefore, Power=Work÷ Time

Therefore, 5joules÷0.50s=10 watts.

A lever has a mechanical advantage of 5.4. If you apply a force of 500 N to the lever, how much force does the lever apply to th
Yanka [14]

Force applied by the lever to the object=2700 N

Explanation:

Mechanical advantage= \frac{LOAD}{EFFORT}

mechanical advantage= 5.4

effort force= 500 N

we need the load force

5.4= load/500

load=2700 N

Thus the force applied by the lever to the object=2700 N

1) the sun (greek name Helios gives heliocentric)
2) A.  Newton's laws of motion can prove this as well as Kepler's Laws
3) D. Inertia keeps it from falling onto the sun and gravity keeps it from going off in a straight line
4) moons.  They orbit planets not suns directly
5) B (International Space Station gives a hint)

if Gabriel kicks the football 50 meters to the west in 3 seconds , what is the velocity of the football?
Svet_ta [14]

Answer:

velocity = 16.67[m/s]

Explanation:

To solve this problem we must use the following expression of speed, where we see the relationship between displacement and time.

velocity = displacement/time [m/s]

displacement = 50 [m]

time = 3 [s]

velocity = 50/3

velocity = 16.67[m/s]

A block of mass 0.454 kg is hung from a vertical spring and allowed to reach equilibrium at rest. As a result, the spring is str
zloy xaker [14]
<h2>Spring constant is 6.73 N/m</h2>

Explanation:

For a spring mass system we have

           Mass x Acceleration due to gravity = Spring constant x Elongation

           mg = kl

Mass, m= 0.454 kg

Acceleration due to gravity, g = 9.81 m/s²

Spring constant,k = ?

Elongation, l = 0.662 m

Substituting

           0.454 x 9.81 = k x 0.662

            k = 6.73 N/m

Spring constant is 6.73 N/m
