Answer:

  r = 0.765 m

Explanation:

For this exercise let's use the law of universal gravitation

        F = G \ \frac{m_1m_2}{r^2}

        r = \sqrt{G \frac{m_1m_2}{F} }

let's reduce the magnitudes to the SI system

         m₁ = 250 g (1 kg / 1000g) = 0.250 kg

         m₂ = 650 g (1 kg / 1000g) = 0.650

         F = 1.85 10-6 dynes (1 N / 10⁵ dynes) = 1.85 10-11 N

let's calculate

        r = \sqrt{ \frac{ 6.67 \ 10^{-11} \ 0.250 \ 0.650}{1.85 \ 10^{-11}} }

        r = √0.58587

        r = 0.765 m

Explain the difference between mass and weight for objects on earth and on the moon
blsea [12.9K]

Answer: Gravity causes a change in the mass of objects on earth and the moon.

Explanation:

Because of gravity, the weight of objects lessen, and decrease because of gravity. If you were to drop an object from earth from space, the object would have more mass. Hope that helps.

a tennis ball is hit upward with a tennis racket an initial velocity of 12 m/s. What will the ball's speed be when it returns to
zaharov [31]

Answer: 12 m/s

Explanation:

If we ignore air resistance, gravity alone will reduce the upward velocity to zero at the top of the flight. As gravity is a conservative force, it will return exactly the same amount of energy to the tennis ball when it returns to the original elevation.

An electron is moving through a magnetic field whose magnitude is 9.21 × 10^-4 T. The electron experiences only a magnetic force
Marysya12 [62]

Answer:

\theta=10.60^{\circ}

Explanation:

Given that,

Magnetic field, B=9.21\times 10^{-4}\ T

Acceleration of the electron, a=2.3\times 10^{14}\ m/s^2

Speed of electron, v=7.69\times 10^{6}\ m/s

The force due to this acceleration is balanced by the magnetic force as :

ma=qvB\ sin\theta

sin\theta=\dfrac{ma}{qvB}

sin\theta=\dfrac{9.1\times 10^{-31}\times 2.3\times 10^{14}}{1.6\times 10^{-19}\times 7.69\times 10^{6}\times 9.21\times 10^{-4}}

\theta=10.60^{\circ}

So, the angle between the electron's velocity and the magnetic field is 10.6 degrees. Hence, this is the required solution,

A women who normally weighs 400 N stands on top of a ladder so high she is one full additional earth radius above the surface of
AveGali [126]

The woman weighs 100N now.

Explanation:

Given:

F is given as 400N

one full additional earth radius formed

To Find:

Weight of the woman=?

Solution:

We know that gravitational force is inversely proportional to the square of radius.

f_g=\frac{1}{r^2}

where

f_g is the gravitational force

r^2 is the radius square

So when radius is doubled, the force becomes one fourth of the original.

Therefore \frac{1}{4} \times400 = 100N
