The gravitational force between a satellite and Earth’s moon is 324 N. The mass of the moon is 7. 3 × 1022 kg. If the distance f

rom the moon to the satellite is 2. 6 × 106 m, what is the mass of the satellite? 1. 7 × 10–4 kg 2. 2 × 10–3 kg 230 kg 450 kg.

The gravitational force is s type of force that has the ability to attract any two objects with mass. The mass of the satellite will be 450 kg.

<h3>What is the gravitational force?</h3>

The gravitational force is s type of force that has the ability to attract any two objects with mass. Gravitational force tries to pull two masses towards each other.

The given data in the problem is;

F is the gravitational force = 324 N,

m₁ is the mass of the moon = 7.3 * 10²²kg

r is the distance between the moon and satellite  = 2.6 * 10 ⁶m.

m₂ is the mass of satelite =?

G is the gravitational constant = 6.67×10⁻¹¹

The gravitational force is given by

\rm F= \frac{Gm_1m_2}{r^2} \\\\ \rm m_2 = \frac{Fr^2}{Gm_1} \\\\  \rm m_2 = \frac{324 \times (2.6\times 10^6)^2}{6.67\times 10^{-11} \times 7.3 \times 10^22 } \\\\ \rm m_2= 450 kg

Hence the mass of the satellite will be 450 kg.

omeli [17]

Answer:

The mechanical energy is converted to potential energy while the kinetic energy is zero

Explanation:

mechanical energy is the sum of potential energy and kinetic energy. It is the energy associated with the motion and position of an object. The total mechanical energy is the sum of these two forms of energy.

The Law of Conservation of Energy: Energy cannot be created or destroyed, but is merely changed from one form into another. This means that potential energy can become kinetic energy, or vice versa, but energy cannot “disappear”.

The mechanical energy is converted to potential energy while the kinetic energy is zero

A river flows due south with a speed of 2.0 m/s. You steer a motorboat across the river; your velocity relative to the water is
neonofarm [45]

Answer:

a) 25.5°(south of east)

b) 119 s

c) 238 m

Explanation:

solution:

we have river speed v_{r}=2 m/s

velocity of motorboat relative to water is v_{m/r}=4.2 m/s

so speed will be:

a) v_{m}=v_{r}+v_{m/r}

solving graphically

v_{m}=\sqrt{v^2_{r}+v^2_{m/r}}

     =4.7 m/s

Ф=tan^{-1} (\frac{v_{r}}{v_{m/r}} )

  =25.5°(south of east)

b) time to cross the river: t=\frac{w}{v_{m/r}}=\frac{500}{4.2}=119 s

c) d=v_{r}t=(2)(119)=238 m

A car with a mass of 1500 kg accelerates when the traffic light turns green. If the net force on the car is 3750 newtons, what i
timurjin [86]

Answer:

2.5 ms⁻²

Explanation:

By Newton's 2nd law,

The rate of change of momentum is directly proportional to the unbalance force applied on the object,

By that you can get the equation,

F = ma ⇒ a = F/m

where terms are in usual meaning

a = 3750/1500 = 2.5 ms⁻²
