Answer:

50.2 cm

Explanation:

We have the following data:

Height, h=3.5 m

Initial horizontal velocity, u_x=15 m/s

Time, t=0.32 s

We need to determine how far the ball is from the ground after 0.32 s.

Initial vertical velocity, u_y=0

s=u_yt+\frac{1}{2}gt^2

Where g=9.8 m/s^

s=0+\frac{1}{2}(9.8)(0.32)^2

s=0.502 m

s=0.502\times 100=50.2 cm

A hydraulic lift raises a 2000 kg automobile when a 500 N force is applied to the smaller piston. If the smaller piston has an a
kicyunya [3294]

Answer:

The cross-sectional area of the larger piston is 392cm ^{2}[/tex]

Explanation:

To find the solution, we apply the following equation:

Pascal's principle: F=P*A   Formula (1)

F=Force applied to the piston

P: Pressure

A= Area of the piston

Nomenclature:

Fp= Force on the primary piston= 500N

W= weight of the car =m*g=2000kg*9.8m/s2= 19600N

Fs= Force on the secondary piston= W = 19600N

Ap= Primary piston area=10cm^{2} =10*10^{-4}m^{2}

As= Area of the secondary piston=?

Pressure applied on one side is distributed to all liquid molecules since liquids are incompressible.

From equation (1)

P=F/A

Pp=Ps

\frac{Fp}{Ap} = \frac{Fs}{As}

As= \frac{Fs*Ap}{Fp}

As=\frac{19600*10*10^{-4} }{500}

As=0.0392m^{2} =0.0392*10^{4}cm^{2}

As=392cm ^{2}

A kinesin that is transporting a secretory vesicle uses approximately 80 ATP molecules/s. Each ATP provides a kinesin molecule w
inna [3103]

Answer:

The force is  F = 8*10^{-12} \ N

Explanation:

According to the inquiry, we understand that

     The rate at which ATP molecules are utilized is R = 80 ATP/ s

       The energy yielded by a single ATP molecule is  E_{ATP} = 0.8 * 10^{-19} J

       The kinesin's velocity is  v = 800 nm/s = 800*10^{-9} m/s

The power generated by the ATP in one second can be expressed mathematically as

       P = E_{ATP} * R

After substituting the values

       P = 80 * 0.8*10^{-19 }

       P = 6.4 *10^{-18}J/s

Now this power can be represented mathematically as

       P = F * v

Where  F indicates the force exerted by the kinesin

Therefore

          F = \frac{P}{v}

after substituting input values

            F = \frac{6.4*0^{-18}}{800 *10^{-9}}

           F = 8*10^{-12} \ N

Ostrovityanka [3204]

All the weight of the wooden board rests solely on the support situated at the center of the rod, while the other support positioned at one end experiences no reaction force, resulting in a 0 reaction force.

Thus, the reaction force at the central support corresponds to the weight of the board, whereas the end support has 0 reaction force.
