If each day the satelite orbits the earth its going faster than the moon and is passing it, so the satellite continuously moves closer and further away from the moon. like if you were standing watching a race then the racers would be moving away then towards you then away again

Answer: D.The satellite continuously move closer and farther away from the moon.

The moon rotates on its axis and revolves around Earth in 27 days. The satellite is orbiting Earth once per day.

In moon 's frame of reference, the satellite would be in motion. Sometime it would be away and sometimes closer. From moon, we would observe satellite to rotate about the Earth. The satellite would get eclipsed by the Earth sometimes when it would go behind it as viewed from moon.

If half of the weight of a flatbed truck is supported by its two drive wheels, what is the maximum acceleration it can achieve o
Scilla [17]

Answer:

Maximum acceleration will be equal to 3.43m/sec^2

Explanation:

We have given coefficient of kinetic friction \mu _k=0.7

And coefficient of static friction \mu _s=1

Acceleration due to gravity g=9.8m/sec^2

When truck moves maximum force will be equal to F=\mu _kmg

It is given that half of the weight is supported by its drive wheels

So force required =\frac{\mu _kmg}{2}

From newtons law maximum acceleration will be equal to a=\frac{\frac{\mu _kmg}{2}}{m}=\frac{\mu _kg}{2}=\frac{0.7\times 9.8}{2}=3.43m/sec^2

A substance with a density of 16.8 g/ml has a mass of 3.2 g. what is its volume?
wel
We know that d=m/v where d is density, m is mass and v is volume. Lets transform formula to get v in times of d and m
d= \frac{m}{V}  /*V \\ V*d=m /:d \\ V= \frac{m}{d}
Now we have to substitute our data to formula
V=\frac{3.2}{16.8}=0.19 ml - its the answeer

what happens when light travels from one medium to another with a different index of refraction at a zero degree angle of incide
zaharov [31]

Answer:

No Refraction takes places

Explanation:

When light travels from one medium to another at an angle of incidence 0 degree then no refraction takes place .

It is because according to Refraction law

                    n_{i}sini = n_{r}sinr

where n_{i} ,n_{r} are the refractive index of medium of incidence and medium of refraction .

When i = 0 , left side of the equation becomes 0 and thus r (angle of refraction) must be zero. So No refraction takes place

2. Three charged particles are placed at the corners of an equilateral triangle of side 1.20 m. The charges are +7.0μC, -8.0 μC
Scorpion4ik [409]

Answer:

0.53 N, 25.6°

Explanation:

side of triangle, a = 1.2 m

q = 7 μC

q1 = - 8 μC

q2 = - 6 μC

Let F1 be the force between q and q1

By using the coulomb's law

F_{1}=\frac{Kq_{1}q}{a^{2}}

F_{1}=\frac{9\times 10^{9}\times 7\times 10^{-6}\times 8\times 10^{-6}}{1.2^{2}}

F1 = 0.35 N

Let F2 be the force between q and q2

By using the coulomb's law

F_{2}=\frac{Kq_{2}q}{a^{2}}

F_{2}=\frac{9\times 10^{9}\times 7\times 10^{-6}\times 6\times 10^{-6}}{1.2^{2}}

F2 = 0.26 N

Write the forces in the vector form

\overrightarrow{F_{1}}=0.35\widehat{i}

\overrightarrow{F_{2}}=0.26\left ( Cos60 \widehat{i}+Sin60\widehat{j}\right )

\overrightarrow{F_{2}}=0.13 \widehat{i}+0.23\widehat{j}

Net force

\overrightarrow{F}=\overrightarrow{F_{1}}+\overrightarrow{F_{2}}

\overrightarrow{F}=0.48 \widehat{i}+0.23\widehat{j}

Magnitude of the force

F=\sqrt{0.48^{2}+0.23^{2}}

F = 0.53 N

Direction of force with x axis

tan\theta =\frac{0.23}{0.48}

θ = 25.6°
