Answer:

Ft = - 23.99 10₁₉₉9 N

Explanation:

In this exercise we will use the law of universal gravitation

F = G m₁ M₂ / r²

With Newton's second law we get

Ft = F1 - F2

Where F1 is the force of attraction between the moon and the Earth

F1 = G m₁ M₂ / r²

F1 = 6.67 10⁻¹¹ 7.36 10²² 5.98 10²⁴ /(3.84 10⁸)²

F1 = 19,909 10¹⁹ N

Let's calculate the force of attraction between the Sun and the moon (F2)

The distance from the sun to the moon is the distance from the sun to the Earth minus the distance from the earth to the moon

R = 1,496 10¹¹ - 3.84 10⁸ = (1496 - 3.84) 10⁸ m

R = 1492.2 108 m

F2 = 6.67 10⁻¹¹ 7.36 10²² 1,991 10³⁰ /(1492.2 10⁸)²

F2 = 4.3896 10²⁰

Ft = 19,902 10¹⁹ - 43,896 10¹⁹

Ft = - 23.99 10₁₉₉9 N

The negative sign indicates that the force is directed towards the sun

If the car’s speed decreases at a constant rate from 64 mi/h to 30 mi/h in 3.0 s, what is the magnitude of its acceleration, ass

mixas84 [53]

Answer: $3.874 m/s^2$

Explanation:

Given

Car speed decreases at a constant rate from 64 mi/h to 30 mi/h

in 3 sec

$60mi/h \approx 26.8224m/s$

$34mi/h \approx 15.1994 m/s$

we know acceleration is given by $=\frac{velocity}{Time}$

$a=\frac{15.1994-26.8224}{3}$

$a=-3.874 m/s^2$

negative indicates that it is stopping the car

Distance traveled

$v^2-u^2=2as$

$\left ( 15.1994\right )^2-\left ( 26.8224\right )^2=2\left ( -3.874\right )s$

$s=\frac{488.419}{2\times 3.874}$

s=63.038 m

Two objects, A and B, each of mass o.22 kg, are moving at 0.34 m/s directly toward each other. What is the speed of Object A aft

ki77a [65]

Theoretically, if the objects have the same mass and are moving towards each other at a speed of $0.34m s^{-1}$ , after a perfectly elastic collision, the object A is supposed to move with the same velocity in the opposite direction.

Two parallel plates are 1 cm apart and are connected to a 500 V source. What force will be exerted on a single electron half way

VladimirAG [237]

Answer: 8*10^-15 N

Explanation: In order to calculate the force applied on an electron in the middle of the two planes at 500 V we know that, F=q*E

The electric field between the plates is given by:

E = ΔV/d = 500 V/0.01 m=5*10^3 N/C

the force applied to the electron is: F=e*E=8*10^-15 N

How can you say that joule and Newton are derived units

maxonik [38]

Answer:

F = M a where M is acceleration and a is acceleration

a = x / s^2 = distance / time squared

The Newton is derived because mass, distance, and time are all fundamental units One would have to look at the fundamental requirements for these definitions, but they can all be repeated in a laboratory.

So the Newton is determined from these fundamental units and since the Joule equals Newton * Distance it is also derived from the fundamental units.

If one has the three fundamental units then one can derive the Joule and Newton.
