Answer:C: multiply the input force

Explanation:

A lever is a simple machine consisting of a bar pivoted or supported at a point (known as Fulcrum) about which it can rotate to perform the task.

Mechanical Advantage MA = $\frac{E}{L}=\frac{F_{L}}{F_{E}}$

where E→ length of effort arm from the pivot

L→ length of load arm from the pivot

$F_{E}$ → force on the end of effort arm

$F_{L}$ → force on the end of load arm

By the law of conservation of angular momentum:-

$F_{E}\times E$ = $F_{L}\times L$

A student team is to design a human powered submarine for a design competition. The overall length of the prototype submarine is

Allushta [10]

Answer:

a) The speed is 61.42 m/s

b) The drag force is 10.32 N

Explanation:

a) The Reynold´s number for the model and prototype is:

$Re_{m} =\frac{p_{m}V_{m}L_{m} }{u_{m} }$

$Re_{p} =\frac{p_{p}V_{p}L_{p} }{u_{p} }$

Equaling both Reynold's number:

$\frac{p_{p}V_{p}L_{p} }{u_{p} }=\frac{p_{m}V_{m}L_{m} }{u_{m} }$

Clearing Vm:

$V_{m} =\frac{p_{p}V_{p}L_{p} u_{m} }{u_{p} p_{m} L_{m} }=\frac{999.1*0.56*8*1.849x10^{-5} }{1.138x10^{-3}*1.184*1 } =61.42m/s$

b) The drag force is:

$\frac{F_{Dm} }{p_{m}V_{m}^{2}L_{m}^{2} } =\frac{F_{Dp} }{p_{p}V_{p}^{2}L_{p}^{2} } \\F_{Dp} =\frac{F_{Dp}p_{p}V_{p}^{2}L_{p}^{2} }{p_{m}V_{m}^{2}L_{m}^{2} } \\F_{Dp}=\frac{2.3*999.1*0.56^{2} *8^{2} }{1.184*61.42^{2}*1^{2} } =10.32N$

An object that has kinetic energy must what ?

11Alexandr11 [23.1K]

An object that has kinetic energy must be moving.

The formula for an object's kinetic energy is

KE = (1/2) · (the object's mass) · (the object's speed)²

As you can see from the formula, if the object has no speed, then its kinetic energy is zero. That's why kinetic energy is usually called the "energy of motion", and if an object HAS kinetic energy, then that tells you right away that it must be moving.
