Answer:

Fs/Fm = 176.8

Explanation:

The tidal force due to a planet on earth can be given by Newton's Law of Gravitation:

F = Gm₁m₂/r²

where,

F = Tidal Force = ?

G = Gravitational Constant

m₁ = mass of 1st planet

m₂ = mass of 2nd planet

r = distance between the planets

<u>FOR TIDAL FORCE DUE TO SUN</u>:

m₁ = Mass of Earth

m₂ = Mass of Sun = 1.989 x 10³³ g

r = distance between earth and sun = 1.5 x 10⁸ km

F = Fs

Therefore,

Fs = Gm₁(1.989 x 10³³ g)/(1.5 x 10⁸ km)²

Fs = Gm₁(1.989 x 10³³ g)/(2.25 x 10¹⁶ km²)

Fs = Gm₁(8.84 x 10¹⁶ g/km²) ----- equation 1

<u>FOR TIDAL FORCE DUE TO MOON</u>:

m₁ = Mass of Earth

m₂ = Mass of Moon = 7.35 x 10²⁵ g

r = distance between earth and moon = 3.84 x 10⁵ km

F = Fm

Therefore,

Fm = Gm₁(7.35 x 10²⁵ g)/(3.84 x 10⁵ km)²

Fm = Gm₁(7.35 x 10²⁵ g)/(14.74 x 10¹⁰ km²)

Fm = Gm₁(5 x 10¹⁴ g/km²) ----- equation 2

Dividing equation 1 by equation 2 we get:

Fs/Fm = Gm₁(8.84 x 10¹⁶ g/km²)/Gm₁(5 x 10¹⁴ g/km²)

A 4.79 g bullet moving at 642.3 m/s penetrates a tree trunk to a depth of 4.35 cm. Use work and energy considerations to find th

vladimir1956 [14]

Answer:

Force, $F=2.27\times 10^4\ N$

Explanation:

Given that,

Mass of the bullet, m = 4.79 g = 0.00479 kg

Initial speed of the bullet, u = 642.3 m/s

Distance, d = 4.35 cm = 0.0435 m

To find,

The magnitude of force required to stop the bullet.

Solution,

The work energy theorem states that the work done is equal to the change in its kinetic energy. Its expression is given by :

$F.d=\dfrac{1}{2}m(v^2-u^2)$

Finally, it stops, v = 0

$F.d=-\dfrac{1}{2}m(u^2)$

$F=\dfrac{-mu^2}{2d}$

$F=\dfrac{-0.00479\times (642.3)^2}{2\times 0.0435}$

F = -22713.92 N

$F=2.27\times 10^4\ N$

So, the magnitude of the force that stops the bullet is $2.27\times 10^4\ N$

In a classroom demonstration, the pressure inside a soft drink can is suddenly reduced to essentially zero. Assuming the can to

umka2103 [35]

Answer:

3141N or 3.1 ×10³N to 2 significant figures. The can experiences this inward force on its outer surface.

Explanation:

The atmospheric pressure acts on the outer surface of the can. In order to calculate this inward force we need to know the total surface area of the can available to the air outside the can. Since the can is a cylinder with a total surface area given by 2πrh + 2πr² =

A = 2πr(r + h)

Where h = height of the can = 12cm

r = radius of the can = 6.5cm/2 = 3.25cm

r = diameter /2

A = 2π×3.25 ×(3.25 + 12) = 311.4cm² = 311.4 ×10-⁴ = 0.031m²

Atmospheric pressure, P = 101325Pa = 101325 N/m²

F = P × A

F = 101325 ×0.031.

F = 3141N. Or 3.1 ×10³ N.

Help me I do not understand

ololo11 [35]

Answer:

170N

Explanation:

First add 530N to 150N and you get 680N, then add 400N to 450N and get 850N. So subtract 850N by 680N and you get 170N

ehicle collisions involve huge amounts of energy. How does the crashworthiness of a car affect the transfer and transformations

Angelina_Jolie [31]

When the two-vehicle collides transformation of the energy is done in terms of kinetic energy.

<h3>What is the law of conservation of energy?</h3>

According to the Law of Conservation of Energy, energy can neither be created nor destroyed, but it can be transferred from one form to another.

The total energy is the sum of all the energies present in the system. The potential energy in a system is due to its position in the system.

In the above problem, the Vehicle get collides so that the kinetic energy of the vehicle is converted into the kinetic energy of another vehicle the speed of the vehicle will reduce when they collide.

Momentum also gets conserved when the two vehicles collide.

Hence, the transformation of the energy is done in terms of kinetic energy.
