Answer:

The potential difference between the plates is 596.2 volts.

Explanation:

Given that,

Capacitance C=260\ pF

Charge q=0.155\ \mu\ C

Separation of plates = 0.313 mm

We need to calculate the potential difference between the plates

Using formula of potential difference

V= \dfrac{Q}{C}

Where, Q = charge

C = capacitance

Put the value into the formula

V=\dfrac{0.155\times10^{-6}}{260\times10^{-12}}

V=596.2\ volts

Hence,The potential difference between the plates is 596.2 volts.

05. The time required to complete one lap around a perfectly circular track having a radius of 1,835 meters is 86
likoan [24]

Answer:

v = 134.06 m/s

Explanation:

Given that,

Radius of a circular track is 1,835 m

Time required to complete one lap around a perfectly circular track is 86 seconds

We need to find the car's velocity. Velocity is equal to,

v=d/t

On circular path,

v=\dfrac{2\pi r}{t}\\\\v=\dfrac{2\pi \times 1835}{86}\\\\v=134.06\ m/s

So, car's velocity is 134.06 m/s.

At the end of the movie Titanic, Rose lies on a piece of furniture, floating in the ocean, and Jack drowns. A common objection p
julsineya [31]

Answer:

If jack is in the piece of furniture it would submerge.

Explanation:

The piece of furniture would submerge if the  weight applied on the furniture is greater than the maximum buoancy force the water can provide.

maximum buoacy force = density of liquid × volume submerged× acceleration due to gravity.

                                       = 1025\times v\times 9.8

v = area × thickness of pine

  1.5\times 5\times 10^{-2}

 = 0.075 m^{3}

therefore buoancy force = 1025×0.075×9.8 N

                                         = 753.375 N

weight of rose alone = 46×9.8 N = 450.8 N

weight of jack alone = 58×9.8 = 568.4 N

weight of pine = density of pine × volume of pine

                        = 350 × 0.075= 26.25 N

weight of pine + weight of rose = 450.8+26.25=477.05 N

weight of pine + rose + jack = 477.05 + 568.4 = 1045.45 N

therefore if jack is in the piece of furniture it would submerge.

In a track and field event, a hammer thrower accelerates the hammer (mass = 7.30 kg) from rest within four full turns (revolutio
lubasha [3.4K]

Answer:

5.69755 rad/s²

Explanation:

r = Radius = 1.3 m

v = Velocity of the hammer = 22 m/s

n = Number of revolutions = 4

Angular displacement

\theta=n\times 2\pi\\\Rightarrow \theta=4\times 2\pi\\\Rightarrow \theta=8\pi

\omega_i = Initial angular speed = 0

Final angular speed

\omega_f=\frac{v}{r}\\\Rightarrow \omega_f=\frac{22}{1.3}\\\Rightarrow \omega_f=16.92307\ rad/s

Angular acceleration

\alpha=\frac{\omega_f^2-\omega_i^2}{2\theta}\\\Rightarrow \alpha=\frac{16.92307^2-0^2}{2\times 8\pi}\\\Rightarrow \alpha=5.69755\ rad/s^2

Angular acceleration is given by 5.69755 rad/s²

The of the line on a velocity vs. time graph represents acceleration.
erastova [34]

Answer:

True

Explanation:

If you are determining whether the statement is true or false, the answer would be true.

A velocity versus time graph can give information about the acceleration of an object. Acceleration is the change in velocity over time, so the line thatis formed by from different points can tell you whether the object has accelerated, decelerated, or is at a constant velocity.

Velocity is placed on the y-axis, while time is on the x-axis. If you see the line or the slope going upwards, this means that the object is accelerating. If the slope is going downwards, this means that the object is decelerating. If the line is parallel to the x-axis then that means the object is at constant velocity.
