What is the period of a sound wave having frequency of 340 hertz

Answers

Answer 1

Answer: The period and the frequency are reciprocals of each other.

   Frequency = 1 / (period)
and
   Period = 1 / (frequency)

   = 1 / (340 per second) = 0.0029... second (rounded)

Two charged objects, A and B, exert an electric force on each other. What happens if the distance between them is increased?

Answers

The correct answer to the question will be that the electric force between them will be decreased.

EXPLANATION:

Let us consider the charge contained by A and B are denoted as Q and Q' respectively.

Let R is the separation distance between them.

As per Coulomb's law in electrostatics, the force of attraction or repulsion between the two charge bodies A and B will be -

Coulombic force F = $(1)/(4\pi \epsilon) (QQ')/(R^2)$

Here, $\epsilon$ is the permittivity of the medium in which the charges are present.

From above, we see that electric force is inversely proportional to the square of separation distance between them.

Mathematically it can be written: $F\ \alpha\ (1)/(R^2)$

As per the question, the distance between A and B is increased.

Hence, the electric force between A and B will be decreased.

I agree with Hussein but I would like to add that when the distance between two charged objects increase, the force decreases by the Coulomb` s Law:
F= k * Q1*Q2 / r^2
where k is constant Q1, Q2-quantity of electricity and r- distance between two charged objects. So when you increase r, you divide with greater number and result decreases.
$F=k(q1 * q2)/( r^(2) )$

A ski jumper competing for an Olympic gold medal wants to jump a horizontal distance of 135 meters. Thetakeoff point of the ski jump is at a height of 25 meters. With what horizontal speed must he leave the jump?
a. What do you know?
b. What do you need to solve for?
c. What equation(s) will you use?
d. What is the solution to this problem?

Answers

A. We know that the height (h) = 25 m, and the distance (x) = 135 m.

B. We need to find the time flight first (t), then we can find easily the horizontal velocity ( $v_(x)$ . )

C. Because this is a projectile motions, so horizontal velocity is constant, but the vertical velocity is change because of the gravitational acceleration.
So we can use : $h = (1)/(2) g t^(2)$ ,

Note : Time that will be exist is a time from a land to the takeoff point, that can be called as the time flight.
Then we use, $x = v_(x) t$ , to find the horizontal velocity.

D. We know that :
$h = (1)/(2) g t^(2)$ , so by insert the numbers, and assune that the (g = 10 m/ $s^(2)$ ), we get that ( t = $√(5)$ . )
After that by using $x = v_(x) t$ , we can get that $v_(x) = 27 √(5)$

An object that is farther from a converging lens than its focal point always has an image that is _____.inverted
virtual
the same in size
smaller in size

Answers

An object that is farther from a converging lens than its focal point always has an image that is virtual. Option (b) is correct.

An optical lens that is thicker in the center and narrower at the corners is referred to as a converging lens, also known as a convex lens. Because it causes parallel light rays to converge or come together at a certain location known as the focal point, it is referred to as a "converging" lens.

The image created is virtual, meaning that it appears to be on the same side of the lens as the object when an object is placed farther away from a converging lens than its focal point. The virtual image is also enlarged, making it look bigger than the actual object. Additionally, the image is upright, not inverted.

Hence, an object that is farther from a converging lens than its focal point always has an image that is virtual. Option (b) is correct.
