What is an example of frequency

Answers

Answer 1

Answer:
'Frequency' is a word that often confuses some people ... for no good reason.
It just means "frequent-ness" or "often-ness" ... how often something happens.

The SI unit of frequency is the Hertz (Hz). Hz means 'per second'.
So " 13 Hz " means 13 per second.

Here are examples of frequency:

-- 780 kilohertz (on your AM radio dial)
-- 98.7 Megahertz (on your FM dial)
-- 5.8 Gigahertz
-- twice a day
-- three per week
-- every 6 months

Answer 2

Answer: For example 75 Hertz means that there are 75 wave tops per second in for example a radio signal.

What variables affect the acceleration of an object and in what manner do they affect the acceleration?

Answers

Acceleration, in physics, is the rate of change of velocity of an object. An object's acceleration is the net result of any and all forces acting on the object, as described by Newton's Second Law.

A rectangular glass block of dimensions 8.0 cm by 15.0 cm by 3.0 cm weighs 10.5 N. Calculate the minimum and the maximum pressure the bock can exert when it rests on a horizontal table.---
Please answer this asap!

Answers

The pressure can be solved using the following formula:

P = mg / A

Where: P = pressure
mg = mass * gravity = W = 10.5 N
A = l*w

Solving for A (maximum):

A = 8*3
A = 24 sq. cm

Solving for A (minimum):

A = 15*8
A = 120 sq. cm

Substituting into the first equation:

Pmax = 10.5 N / 24 sq.cm
Pmax = 0.4375 Pa

Pmin = 10.5 N / 120 sq.cm
Pmin = 0.0875 Pa

A low-pressure sodium vapor lamp whose wavelength is 5.89 x 10^−7 m passes through double-slits that are 2.0 x 10^−4 m apart and produces an interference pattern whose fringes are 3.2 x 10^−3 m apart on the screen. What is the distance to the screen?3 meters

2.7 meters

1.6 meters

1.1 meters

its literally 1.1 meters I got it right

Answers

Answer:

Distance of the screen is approx 1.1 m

Explanation:

As we know that fringe width on Young's double slit experiment is given as

$\beta = (\lambda L)/(d)$

here we know that

$\beta = 3.2 * 10^(-3)$

$\lambda = 5.89 * 10^(-7) m$

$d = 2.0 * 10^(-4) m$

now we have

$3.2 * 10^(-3) = ((5.89 * 10^(-7))L)/(2.0 * 10^(-4))$

$L = 1.1 m$

Answer:

Explanation:

Which of the following is NOT supported by Newton's Second Law?1 The mass of an object will change depending on the force acting on it

2 The greater the force applied on an object, the greater it's acceleration

3 You can find the mass of an object if you know it's acceleration and the forces acting on it

4 Force is equal to the product of mass and acceleration

Answers

Answer:

1. The mass will change depending on the force.

Explanation:

We know that the newton's second law of motion gives the relation between the mass (m) of an object, force (F) applied and the corresponding measure of acceleration (a) of the object. This can be expressed in the form of an equation:

F = ma

Thus force is the product of mass and acceleration. Using this equation we can derive mass of an object, if acceleration and force values are known.

In the given equation, mass is a constant value and mass will not change in any case. Therefore force is directly proportional to amount object will be accelerated. With the increase in force applied on object, amount the object accelerated will increase and vice versa
