The sun appears to move across the sky, because the earth spins on its axis. To a person standing on the earth, the sun subtends

Liono4ka [1.6K]

Answer:

128 seconds

Step-by-step explanation:

The sun subtends an angle $\theta=9.28\times10^{-3}$ rad

Angular velocity equation is $\omega = \frac{\theta}{t}$

where $\omega$ is angular velocity and t is time.

Earth spins at a rate of :

$\omega = \frac{2 \pi rad}{24 h \times \frac{3600 s}{1 h}} = 7.27221\times10^{-5}$ rad/s

Isolating time (t) from angular velocity equation gives:

$\omega = \frac{\theta}{t}$

$t = \frac{\theta}{\omega}$

$t = \frac{9.28\times10^{-3}}{7.27221\times10^{-5}}$

$t = 128 s$

This trapezium is drawn on a centimetre grid. Find the area of the trapezium.

aivan3 [116]

Answer:

20 unit²

Step-by-step explanation:

A trapezium is given to us on the grid and we need to find out the area of the trapezium . In order to find the area , we need to find the measure of the parallel sides and the distance between the parallel sides.

From the grid :-

$\rm\implies Side_1 = 7 \ units$

$\rm\implies Side_2 = 3 \ units$

$\rm\implies \perp \ Distance =4 \ units$

Now here we got the two parallel sides of the trapezium and the distance between the two parallel sides. Now we can find the area as ,

$\rm\implies Area_{Trapezium}= \dfrac{1}{2}\times ( s_1 + s_2) \times \perp \ Distance \\\\\rm\implies Area = \dfrac{1}{2} \times ( 7 + 3 ) \times 4 \ unit^2 \\\\\rm\implies Area = \dfrac{1}{2} \times ( 10) \times 4 \ unit^2 \\\\\rm\implies\boxed{\rm Area = 20 \ unit^2}$
