Answer : Yes, distance measurements based on the speed of light used for objects in space.

Explanation : A light year is measurement of distance that light travel in a one year.

In a one year light travels 9460000000000 kilometer.

We know that, speed of light is $3\times10^{8}\ m/s$

and time is 31536000 seconds in 1 year

so, distance = speed of light X time

Now, the light year is $9.4608\times10^{15} meter$

Example : The nearest star to earth is about 4.3 light year away.

Dafna1 [17]

Light travels in a straight line because it doesn't usually interact with its medium. When it does it is called refraction.

If a personal pan pizza (6 inches in diameter) has 600 calories, how many calories would you consume if you were to eat a large

Neko [114]

Answer:

2400 calories

Explanation:

given,

diameter of pizza,d₁ = 6 inches

calories of the 6 inches pizza = 600 calories

diameter of large size of pizza, d₂ = 12 inches

calories of the 12 inches pizza = ?

Area of the 6 inches pizza

A₁ = π x 3² = 9 π

Area of the 12 inches pizza

A₂ = π x 6² = 36 π

Ratio of 12 inch pizza to 6 inches

= $\dfrac{36\pi}{9\pi}$

= $\dfrac{4}{1}$

calories of the pizza

$\dfrac{x}{600}=\dfrac{4}{1}$

x = 2400 calories

Pizza of 12 inches is of calories is equal to 2400 calories

Mithun wants to test if a convex lens produces an inverted image of an object placed at a distance away from the lens. Which of

Elis [28]

Answer:

(D) any of these objects can be used as long as all points on the object lie farther away from the lens than the focal length of the lens.

Points lying between the focal point and the lens will be erect and will not form an object visible on a screen.

You have just landed on Planet X. You release a 100-g ball from rest from a height of 10.0 m and measure that it takes 3.40 s to

Nana76 [90]

Answer:

w = 0.173 N

Explanation:

The weigh of any object is computed by multiplying its mass to the acceleration of gravity, so we need to find the gravity on that planet in order to compute the weigh we want.

The ball has a mass of 0.1 kg and its released from a height of 10 m, therefore it is in a free fall motion with gravity acting as a constant acceleration on the body, we can use the equations for free fall movement in order to determine the value for this acceleration:

y(t) = v_0 * t + y_0 - 0.5 * g * t^2

y(t) is the position in the end of the movement, when t = 3.4 s, so y(t) = 0 m.

v_0 is the initial velocity, in this case v_0 = 0 m/s.

y_0 is the initial position of the ball, in this case it is 10 m.

g is the gravity that we want to know.

Applying these values in the equation we have:

0 = 0*(3.4) + 10 - 0.5*g*(3.4)^2

0 = 10 - 0.5*11.56*g

0 = 10 -5.78*g

5.78*g = 10

g = 1.73 m/s^2

Then we can use this value to find out the weigh of the ball in that planet:

w = g*m = 0.1*1.73 = 0.173 N
