The electric flux is - 4.80 × 10∧5 N m2 C-1

How to calculate the electric flux

Use the formula:

Electric flux, ΦE = EScosθ

Where,

E = electric flux

S = area of the rectangular surface = length × breadth = 6.00 × 3.00 = 18.00 m²

E = magnitude = 2. 70 × 10∧4 N/C

θ = the angle between the electric field lines = 15. 7°

Substitute the values into the equation

EФ = 2. 70 × 10∧4 × 18. 00 × Cos (15.7)

EФ = 2. 70 × 10∧4 × 18. 00 × -0.9999

EФ= - 4.79 × 10∧5 N m2 C-1

Therefore, the electric flux is - 4.80 × 10∧5 N m2 C-1

Why sodium &pottasium are kept under kerosine

Afina-wow [57]

As they are Alkali metals (group 1), they are extremely reactive in both air and water so must be stored in kerosine to stop them from reacting with the air or water.

An ant crawls along a sidewalk with a velocity of 0.1 m/s in a direction that is 45° relative to edge of the sidewalk. If it has

Marat540 [252]

Answer:14 s

Explanation:

Given

Velocity of ant is 0.1 m/s in a direction $45^{\circ}$

if it has traveled 1 m perpendicular to the edge of the sidewalk

i.e. from diagram

$\sin 45=\frac{1}{L}$

$L=\sqrt{2}$

$time=\frac{Distance}{speed}$

$t=\frac{\sqrt{2}}{0.1}$

$t=14.14 s$

A giant wall clock with diameter d rests vertically on the floor. The minute hand sticks out from the face of the clock, and its

Katyanochek1 [597]

Answer:

$d_{x}(t)=(D/2)cos(\frac{\pi}{30}*t)$

Explanation:

We can try writing the equation of the horizontal component of the length of the minute hand in terms of distance and the angle, that depends of time in this particular case.

The x-component of the length of the minute hand is:

$d_{x}(t)=dcos(\theta (t))$ (1)

d is the length of the minute hand (d=D/2)
D is the diameter of the clock
t is the time (min)

Now, using the angular kinematic equations we can express the angle in term of angular velocity and time. As we know, the minute hand moves with a constant angular velocity, so we can use this equation:

$\theta (t)=\omega *t$ (2)

Also we know, that the minute hand moves 90 degrees or π/2 rad in 15 min, so using the definition of angular velocity, we have:

$\omega=\frac{\Delta \theta}{\Delta t}=\frac{\theta_{f}-\theta_{i}}{t_{f}-t{i}}=\frac{\pi/2-0}{15-0}=\frac{\pi}{30}$

Now, let's put this value on (2)

$\theta (t)=\frac{\pi}{30}*t$

Finally the length x(t) of the shadow of the minute hand as a function of time t, will be:

$d_{x}(t)=(D/2)cos(\frac{\pi}{30}*t)$

I hope it helps you!

A 970 kg car starts from rest on a horizontal roadway and accelerates eastward

a_sh-v [17]

Answer: 4850N

Explanation:

Mass of car = 970 kg

Time = 5 s

Speed = 25 m/s

Average force exerted on the car = ?

Recall that Force is the product of the mass of an object and the acceleration by which it moves

i.e Force = mass x acceleration

(Since, acceleration is the rate of change of velocity or speed per unit time)

i.e Acceleration = Speed / Time

Acc = 25m/s / 5s

Acc = 5m/s^2

Average force = mass x acceleration

Avg force = 970 kg x 5m/s^2

= 4850N

Thus, the average force exerted on the car is 4850 Newton
