Answer:

same as

Explanation:

According to Newton's 3rd law, the force that the Earth exert on the Sun would be equal (and in opposite direction) with the force that the Sun exerts on the Earth.

Also Newton's gravitational law states the formula for the attraction between objects with mass, is the same for both objects

Answer:

equal

Explanation:

Newton's law of universal gravitation states that "any two objects A and B exert a gravitational force of attraction on each other and the magnitude of this force is proportional to the product of the masses of the objects and inversely proportional to the square of the distance separating these objects".

This means that two objects interacting together will exert the same force of gravity (or simply gravitational force) on each other. Though the masses of the two objects may be different, the magnitude of the force that one object exerts on the other is still the product of these masses and the inverse of the square of the distance between them.

Therefore, the gravitational force that the Sun, though of higher mass than the Earth, will exert on the Earth is the same as that which the Earth will exert on the Sun.

Two antennas located at points A and B are broadcasting radio waves of frequency 96.0 MHz, perfectly in phase with each other. T
earnstyle [38]

Answer:

a)   Δφ = 1.51 rad , b)  x = 21.17 m

Explanation:

This is an interference problem, as they indicate that the distance AP is on the x-axis the antennas must be on the y-axis, the phase difference is

          Δr /λ = Δfi / 2π

          Δfi = Δr /λ 2π

          Δr = r₂-r₁

let's look the distances

         r₁ = 57.0 m

We use Pythagoras' theorem for the other distance

         r₂ = √ (x² + y²)

         r₂ = √(57² + 9.3²)

         r₂ = 57.75 m

The  difference is

         Δr = 57.75 - 57.0

         Δr = 0.75 m

Let's look for the wavelength

        c =  λ f

          λ = c / f

          λ = 3 10⁸ / 96.0 10⁶

          λ = 3.12 m

Let's calculate

         Δφ = 0.75 / 3.12 2π

         Δφ = 1.51 rad

b) for destructive interference the path difference must be λ/2, the equation for destructive interference with φ = π remains

           Δr = (2n + 1) λ / 2

           

For the first interference n = 0

           Δr = λ / 2

           Δr = r₂ - r₁

We substitute the values

        √ (x² + y²) - x = 3.12 / 2

Let's solve for distance x

          √ (x² + y²) = 1.56 + x

          x² + y² = (1.56 + x)²

          x² + y² = 1.56² + 2 1.56 x + x²

          y2 = 20.4336 +3.12 x

          x = (y² -20.4336) /3.12

          x = (9.3² -20.4336) /3.12

          x = 21.17 m

This is the distance for the first minimum

A person measures his or her heart rate by counting the number of beats in 30s. If 40±1 beats are counted in 30.0±0.5s, what is
nordsb [41]

Answer:

Rate = 1.33 \pm 0.055 beats per second

Explanation:

Number of heart beats = 40 \pm 1

time taken = 30.0 \pm 0.5 s

now we have

N = 40 \pm 2.5%

t = 30.0 \pm 1.67%

now rate of heart beat is defined as number of heart beat per unit of time

so we have

Rate = \frac{N}{t}

Rate = \frac{40 \pm 2.5}{30 \pm 1.67}

so we have

Rate = 1.33 \pm (2.5 + 1.67 )

Rate = 1.33 \pm 4.17%

Rate = 1.33 \pm 0.055 beats per second
