Answer:

Explanation:

Width of slit a = 1 x 10⁻³ / 210

a = 4.76 x 10⁻⁶ m .

angle at which first order peak is formed

= λ / a         (where λ is wavelength and a is width of slit)

given λ = 506 x 10⁻⁹ m

a = 4.76 x 10⁻⁶

θ = 506 x 10⁻⁹ / 4.76 x 10⁻⁶

= 106.3 x 10⁻³ radian .

first order peak is formed  at an angle of 106.3 x 10⁻³ radian .

Enrique is given information about a satellite orbiting Earth. R = 3. 8 Ă— 108 m T = 18 days In order to calculate the tangentia
NISA [10]

The first step that  Enrique must take in order to calculate the tangential speed of the satellite is to convert the period from days to seconds.

We know that the SI unit of speed is meter per second and now, we with to obtain the tangential speed of the satellite.

Since the period is given in days, the first step is to convert the period from days to seconds.

Consider Newton's Law of Universal Gravitation: FG= G (m1 m2)/d2 .
bixtya [17]

Answer:

C

Mass is directly proportional to the Force of Gravity. If Mass increases, then the Force of Gravity increases; however, Distance is indirectly (or inversely) proportional to the Force of Gravity. If Distance increases, then the Force of Gravity decreases.

Explanation:

The formula for the force of gravity between two objects is

F=G\frac{m_1 m_2}{d^2}

where

G is the gravitational constant

m1, m2 are the masses of the two objects

d is the separation between the two objects

We notice the  following:

- F is directly proportional to the masses, F\propto m_1, m_2. This means that if one of the masses increases, then the force between them, F, increases in a proportional way

- F is inversely proportional to the square of the distance, F\propto \frac{1}{d^2}. This means that if the distance between the two objects is increased, the force between them will decrease, and vice-versa.

So, the correct answer is

C

Mass is directly proportional to the Force of Gravity. If Mass increases, then the Force of Gravity increases; however, Distance is indirectly (or inversely) proportional to the Force of Gravity. If Distance increases, then the Force of Gravity decreases.
