The x and y-components of the vector R is 44.15i + 23.47j.

The given parameters:

Magnitude of vector R = 50 m
Position of vector R = 28 degrees

<h3>What is component vectors?</h3>

This is the representation of vectors in x and y-coordinates.

The x and y-components of the vector R is calculated as follows;

$R_x = R \times cos(\theta)\\\\R_y = R \times sin(\theta)\\\\R_x = 50 \times cos(28) = 44.15 \ i\\\\R_y = 50 \times sin(28) = 23.47 \ j$

R is a unit vector.

The plot of vector R is in the image uploaded.

We showed that the length of the pendulum of period 2.000 seconds on the Earth’s surface was 0.99396 meters. What period would t

Kitty [74]

To solve this problem it is necessary to apply the concepts related to the Period based on gravity and length.

Mathematically this concept can be expressed as

$T= 2\pi \sqrt{\frac{l}{g}}$

Where,

l = Length

g = Gravitational acceleration

First we will find the period that with the characteristics presented can be given on Mars and then we can find the length of the pendulum at the desired time.

The period on Mars with the given length of 0.99396m and the gravity of the moon (approximately $1.62m / s ^ 2)$ will be

$T= 2\pi \sqrt{\frac{l}{g}}$

$T= 2\pi \sqrt{\frac{0.99396}{1.62}}$

$T = 4.921seg$

For the second question posed, it would be to find the length so that the period is 2 seconds, that is:

$T= 2\pi \sqrt{\frac{l}{g}}$

$2= 2\pi \sqrt{\frac{l}{1.62}}$

$l = 0.16414m$

Therefore, we can observe also that the shorter distance would be the period compared to the first result given.

Magnesium is a shiny, flexible metal that can be burned in the presence of air.

alukav5142 [94]

Answer:

A new substance was formed

Explanation:

According to this question, a shiny and flexible metal called Magnesium (Mg) is burnt in air to produce a white powder that has no shiny or flexible properties, however, has more weight than the magnesium metal itself.

This is possible because a CHEMICAL CHANGE has occured, hence, a new substance has been formed. The formation of a new substance during the burning process (chemical reaction), induced the increase in mass.

Mars2501 [29]

Answer:

a) $a=5.7551 \times g$

b) $d=20.5539\times g$

Explanation:

Given:

speed of rocket initially, $v_i=0\ m.s^{-1}$

top speed of rocket after acceleration, $v=282\ m.s^{-1}$

time taken to get to the top speed, $t_i=5\ m.s^{-1}$

final speed of the rocket, $v_f=0\ m.s^{-1}$

time taken to get to the final speed after reaching the top speed, $t_f=1.4\ s$

Now the acceleration:

$a=\frac{v-v_i}{t_i}$

$a=\frac{282-0}{5}$

$a=56.4\ m.s^{-2}$

Now as a fraction of gravity:

$a=\frac{56.4}{9.8}\times g$

$a=5.7551 \times g$

Now, the deceleration:

$d=\frac{0-282}{1.4}$

$d=201.4285\ m.s^{-2}$

Now as a fraction of gravity:

$d=\frac{201.4285}{9.8}\times g$

$d=20.5539\times g$
