What is the major factor controlling how levers work?

Physics
1 answer:
Gekata [30.6K]3 years ago
7 0

Answer:

Displacement between Fulcrum, Job and Force

Explanation:

The employment and use of levers is simple. Levers reduce the force required to do a task by introducing the concept of moment.

There are there components in a simple lever.

1) The Fulcrum

2) The Job (Load)

3) The Force (Effort)

Typically if it weren't for levers then the three points/components would be at the same point. A lever creates a displacement between all these three components create moment. The higher the displacement between the three the lower the force (effort) required to do the job (lift the load).

Based on the chemical equation, use the drop-down menu to choose the coefficients that will balance the chemical
MaRussiya [10]

The coefficients in order are 2, 1, 1

<h3>What is balanced chemical equation?</h3>

A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge is the same for both the reactants and the products.

In other words, the mass and the charge are balanced on both sides of the reaction.

According to the given situation,

To balance the the chemical equation,

Step 1 - Add a 2 on the Na2HPO4:

2(Na₂HPO₄)  ⇒ Na4P₂O₇ + H₂O

Step 2 -Next take count of each element on both sides to see if the 2 is balanced or not:

On the left there are 4 Na, 2 H, 2 P, and 8 O

On the right there are 4 Na, 2 H, 2 P, and 8 O

Step 3 - Now we will divide by 2

i.e. 2 NA.H. P

The coefficient of  Na is 2 , Coefficient of H is 1 and Coefficient of P is 1

Therefore,

The coefficients in order are 2, 1, 1.

To what tension (in newtons) must you adjust the screw so that a transverse wave of wavelength 3.33 cm makes 621 vibrations per
PilotLPTM [1.2K]

Answer:

T=9.4 N

Explanation:

We are given that

Mass of wire,m=16.5 g=\frac{16.5}{1000}kg

1 kg=1000g

Length of wire,l=75 cm=75\times 10^{-2}m

1 m=100 cm

Wavelength of transverse wave=\lambda=3.33 cm=3.33\times 10^{-2}m

Frequency=621 Hz

Mass per unit length=m_l=\frac{m}{l}=\frac{16.5}{1000\times 75\times 10^{-2}}=0.022 kg/m

\nu=\frac{v}{\lambda}

v=\nu \lambda

Where\nu=frequency of wave

\lambda=Wavelength of wave

Speed of wave=v

Using the formula

v=3.33\times 10^{-2}\times 621=20.7m/s

v=\sqrt{\frac{T}{m_l}}

v^2=\frac{T}{m_l}

T=v^2m_l

Using the formula

T=(20.7)^2\times 0.022=9.4N

Hence, the tension,T=9.4 N
