Period is the time which is taken by a wave to complete one complete cycle.

Explanation:

The period can also be referred as the time period or the wave period. The period is relevant to the concept of wave and its propagation, which leads to the measurement of its travel, leading to establish the relation between the period and the frequency.

The S. I. unit for the period is seconds. The period is in inverse relationship of proportionality with the frequency, which is the number of cycles completed in a second.

To test the performance of its tires, a car

VLD [36.1K]

Answer:

0.45

Explanation:

Sum of forces in the y direction:

∑F = ma

N − mg = 0

N = mg

There are friction forces in two directions: centripetal and tangential. The centripetal acceleration is:

ac = v² / r

ac = (31 m/s)² / 333 m

ac = 2.89 m/s²

The total acceleration is:

a = √(ac² + at²)

a = √((2.89 m/s²)² + (3.32 m/s²)²)

a = 4.40 m/s²

Sum of forces:

∑F = ma

Nμ = ma

mgμ = ma

μ = a / g

μ = 4.40 m/s² / 9.8 m/s²

μ = 0.45

Alternating Current In Europe, the voltage of the alternating current coming through an electrical outlet can be modeled by the

stealth61 [152]

Answer:

$\frac{50}{\pi }$ Hz

Explanation:

In alternating current (AC) circuits, voltage (V) oscillates in a sine wave pattern and has a general equation as a function of time (t) as follows;

V(t) = V sin (ωt + Ф) -----------------(i)

Where;

V = amplitude value of the voltage

ω = angular frequency = 2 π f [f = cyclic frequency or simply, frequency]

Ф = phase difference between voltage and current.

Now,

From the question,

V(t) = 230 sin (100t) ---------------(ii)

By comparing equations (i) and (ii) the following holds;

V = 230

ω = 100

Ф = 0

But;

ω = 2 π f = 100

2 π f = 100 [divide both sides by 2]

π f = 50

f = $\frac{50}{\pi }$ Hz

Therefore, the frequency of the voltage is $\frac{50}{\pi }$ Hz

What is the force on a 1670kg elevator accelerating at 6m/s square?

marshall27 [118]

As per Newton's 2nd law

we know that

$F = ma$

it is product of mass and acceleration

here we know that

$m = 1670 kg$

also we know that

$a = 6 m/s^2$

so from above equation we have

$F = 1670 * 6$

$F = 10020 N$

so the force here will be 10020 N
