The statement the mechanical advantage of the lever is 16 is False.

<h3>Mechanical Advantage</h3>

Mechanical advantage MA = d/D where

  • d = distance moved by effort and
  • D = distance moved by load

Given that the effort arm is 8 meters long, d = distance moved by effort = 8 m.

Also, given that the resistance arm is 2 meters long, D = distance moved by load = 2 m.

<h3>Calculating the mechanical advantage</h3>

So, substituting the values of the variables into the equation, we have

MA = d/D

MA = 8 m/2 m

MA = 4

Since MA = 4, so, the stament is False.

So, the statement the mechanical advantage of the lever is 16 is False.

levacccp [35]
Need to know the equation for force
F=MA
F is force
M is mass- we need to know the mass
A is acceleration
use "x" for mass

The diagram shows an example of convection.
const2013 [10]

Answer: Option (C) is the correct answer.

Explanation:

When we heat a fluid then the movement within the fluid makes hot (less dense) material to rise and cooler (more denser) material to sink at the bottom. This process is known as convection.

Thus, in the diagram hot (less dense) water will rise and cooler (more dense) water sinks at the bottom.

Therefore, we can conclude that according to the arrow the label belongs to cooler water sinks.

How much force (in Newtons) acts on a 1700 kg car going around a
Daniel [21]

Answer:

b) 4781 N

Explanation:

Because there is a redius do this question is talking about the acceleration force which= mv^2/r

so a=15^2/80=2.8125 m^2/s

so the force will be = m.a

F =1700×2.8125=4781.25 N

3. 3.0*1015 electrons are removed from one side of a parallel plate capacitor and travel to the other side of the capacitor. You
natima [27]

Answer:

True

Q = 480 \mu C

Explanation:

As we know that total charge is always quantized and in the terms of multiples of charge of single electron

so we have

Q = Ne

here we know that

N = 3.0 \times 10^{15}

also we know that

e = 1.6 \times 10^{-19} C

so we have

Q = (3.0 \times 10^{15})(1.6 \times 10^{-19} C)

Q = 480 \mu C

Since this charge is in multiple of micro coulomb units so yes it is possible to measure it

and the magnitude of this charge is given as

Q = 480\mu C
