3 0

Answer:

the number of kilometers north it traveled is 53.03 km

Explanation:

The computation of the number of kilometers north it traveled is shown below:

Given that

The Displacement of 75 km

At east north of 45 degrees

Based on the above information, the number of kilometers is

= 75 × cos 45

= 53.03 km

Hence, the number of kilometers north it traveled is 53.03 km

We simply applied the above formula so that the correct value could come

And, the same is to be considered

What is an electrical charge how does it create electrical current
AveGali [126]

Answer:

Explanation:

The moving charged particles in an electric current are called charge carriers. In metals, one or more electrons from each atom are loosely bound to the atom, and can move freely about within the metal. These conduction electrons are the charge carriers in metal conductors.

The flow of electrons in a direction is known as electric current. The tendency of attraction between the positive and negative charges makes electric current flow through a wire

At what position in its elliptical orbit is the speed of a planet a maximum? when it is closest to the sun when it is farthest f
Phantasy [73]

Answer:

1.when it is closest to the sun

2.when it is midway between its farthest

Explanation:

According to the law of  Kepler's

T ² ∝ r³

T=Time period

r=semi major axis

We also know that time period T given as

T=\dfrac{2\pi r}{v}

v=Speed

v=\dfrac{2\pi r}{T}

v\alpha \dfrac{r}{T}

v\alpha \dfrac{r}{T}

v^2\alpha \dfrac{r^2}{T^2}

v^2\alpha \dfrac{r^2}{r^3}

v^2\alpha \dfrac{1}{r}

v\alpha \dfrac{1}{\sqrt{r}}

So we can say that ,when r is more then the speed will be minimum and when r is low then speed will be maximum.

A sample of gold has a mass of 38.6 grams and a volume of 2 cm3. What is the density of gold
Natali5045456 [20]

Answer:

19.3 g/cm^3

Explanation:

The density of a material is given by

\rho = \frac{m}{V}

where

m is the mass of the sample

V is its volume

for the sample of gold in this problem,

m = 38.6 g

V=2 cm^3

Substituting into the formula, we find the density of gold:

\rho = \frac{38.6}{2}=19.3 g/cm^3
