When you pluck a guitar STRING, the RESULTING sound has a steady tone and lasts a long time. Each successive vibration of the string takes the same time as the PREVIOUS one. We define periodic motion to be a motion that repeats itself at regular time intervals, such as exhibited by the guitar string or by an object on a spring moving up and down. The time to COMPLETE one oscillation remains constant and is called the period T. Its UNITS are usually seconds, but may be any convenient unit of time. The word period refers to the time for some event whether repetitive or not; but we shall be primarily interested in periodic motion, which is by definition repetitive. A concept closely related to period is the frequency of an event. For example, if you get a paycheck twice a month, the frequency of payment is two per month and the period between checks is half a month. Frequency f is defined to be the number of events per unit time. For periodic motion, frequency is the number of oscillations per unit time. The relationship between frequency and period is

What kind of SYSTEM are you: open or closed? As it turns out, this is a physics QUESTION, not a philosophical one. You, like all LIVING things, are an open system, MEANING that you exchange both MATTER and energy with your environment.

Answer:

The density is 2

Explanation : As we know the Density = mass / volume.

Here mass of substance is 10 gm and volume of WATER displaced by the substance us 5 ml ( The density of water is 1 gm/cc).

Formula for density is =

Density = mass / volume

Density of substance = 10/ 5

Hence density of substance is 2

Answer:

To FIND the temperature when both are equal, we set ∘F=∘C where the temperature in Celsius is ∘C and the temperature in FAHRENHEIT is ∘F. This is derived from the equations GIVEN above. So the temperature when both the Celsius and Fahrenheit SCALES are the same is -40 degrees

ANSWER:

Here's your answer

Explanation:

F = 100 N

tau = 60 Nm                  r = 0.6 m

tau = r F

60 = 0.6 F

F = 60 / 0.6

F = 100 N

Answer:

ACCELERATION = CHANGE in VELOCITY ÷ Time

v final velocity = 20m/s

u initial velocity = 50m/s

= (v - u)/t

= (20m/s - 50m/s)/60S

= (-30m/s)/60s

Acceleration = -0.5m/s²

Or

Retardation = 0.5m/s²

★•Friction Force•★

• Friction is the force resisting the relative MOTION of SOLID surfaces, fluid layers, and material elements sliding against each other.
• There are several types of friction: Dry friction is a force that opposes the relative lateral motion of TWO solid surfaces in CONTACT.

Answer:

Deceleration also known as RETARDATION or negative acceleration, is the acceleration acts in the opposite direction of motion and is responsible for reducing the VELOCITY of a BODY. SI unit of deceleration is m/s2. Example: = 5 m/s2.

ANSWER:

The length is made four times.

Explanation:

T=2π √t/G

(a) The length is made four times - 'T' is DIRECTLY proportional to the square root of the

'I' - length of the string and inversely proportional to the acceleration

due to gravity.

Hence the length is doubled when the period is INCREASED by two times.

(b) The acceleration due to gravity is reduced to one - fourth

- when g - acceleration due to gravity,

is reduced by 1/4

th

,

the period is increased by 2 times.

The to-and-fro motion of a simple pendulum is shows the periodic motion (or oscillatory motion).

Explanation:

It will be seen to come back and move on to position C, at an EQUAL distance on the other side of the MEAN position A, and then go on REPEATING this back and forth motion between the two extreme POSITIONS B and C. ... The to-and-fro motion of a simple pendulum is an example of periodic motion (or oscillatory motion).

HIII SORRY I don't KNOW the ANSWER

ANSWER:

the answer is no. 1. 3Rw/2gsnix

Answer:

yes pressure exerted by fluid is equal in all direction but as height of water increase potential energy of water at each level star punching the water level downward so the water level ta the bottom exert MUCH greater force as COMPARED to top level.

Here potential energy (mgh) is dew to g if we PERFORM this experiment in space then g will be zero that is no potential energy for any levels of water so water will exert same pressure from top to bottom.

ANSWER:

khxkhigdhkfhkflhflhflhcihfihfkhxmkhugojg

Explanation:

Initial VELOCITY(u)= 0m/s. [Because it is in rest]

Time taken to accelerate= 0.21s

Distance covered= 110m

Using second equation of MOTION =>

s = ut + ½ at²

As, u = 0

=> a = 2s/t²

=> a = (2*110)

/(0.21)² [By putting the VALUE
