3 0

A wheelbarrow is a 2nd class lever. Your hands on the handles give the effort. The load inside the wheelbarrow is the resistance. The wheel is the fulcrum. When you lift up the handles, the load goes up in the same direction.

Please please answer this! explain the kinetic molecular theory ( i don't understand how they explain it in my lesson so if some
Bess [88]

Answer:

Explanation:

Basically, Kinetic Molecular Theory says that gas particles are in constant motion and that they show perfectly elastic collisions.

An elastic collision is a collision in which there is no net loss in kinetic energy in the system as a result of the collision.

So the kinetic molecular theory says that gas particles stay moving constantly and don't lose energy when they run into each other.

Hope this helps!

How much force is required to move a sled 5 meters if a person uses 60 J of work?
Brut [27]
W=F*S

W - Work
F - Force
S - Distance (from latin word 'spatium)

so...
S= 5 (m)
W=60 (J)

W=F*S
F=W/S
F=60/5=12 J/m = 12 N (Newtons)

A sack of potatoes weighing 16.0-kg falls from a very tall building. At a certain point at the motion downwards, its measured ac
Vitek1552 [10]

Answer:

The terminal speed is 74.833 m/s

Explanation:

The drag force is equal to square of speed:

Fdrag = k*v²

According Newton`s law:

Fnet = m*a

m*g - k*v² = m*a

k=\frac{m(g-a)}{v^{2} }

k=\frac{16*(9.8-4.6)}{54.2^{2} } =0.028

If terminal speed, the net force is zero.

kv_{t} ^{2} =mg\\v_{t} =\sqrt{\frac{mg}{k} } =\sqrt{\frac{16*9.8}{0.028} } =74.833m/s

Rafaela is a physical education teacher and has2525 girls and 3535 boys in herclass.She wants to divide the class into teams of
Paha777 [63]

-- The greatest common factor of 2525 and 3535 is 5.

-- So the greatest possible number of teams is 5.

-- Each of the five teams will have 505 girls and 707 boys.

-- Rafaela is a superwoman !  She's handling more kids in that class than there were in my whole high school !

She has 6,060 students in her class, so I'm not surprised that she wants to divide the class up into smaller groups.  

But come on !  She's going to form 5 teams, and she thinks that her job will be easier that way, because each team will have 'only'  1,212 students on it !

And these are all in one class !  If Rafaela is a physical education teacher, then SURELY she's teaching more than one class !

Or maybe not.  I'll betcha whenever Rafaela is teaching her physical education class, all the other teachers are taking it easy, because Rafaela is responsible for every student in the school that hour.

And possibly several OTHER schools in town too.
