If the mass of the cement is 15 000 kg, calculate the density of this cement sample in kgm-3

Physics
1 answer:
MrRa [10]2 years ago
5 0

Explanation:

Hi there!

Mass of the container (m) = 15000 kg

Also from the figure;

Volume of the container (V) = l*b*h

{ From figure length = 2m , breadth = 1.1m, height = 2.5m}

So,

V = (2*1.1*2.5) m³

= 5.5m³

Then;

Density (d) = m/v

= 15000/5.5

= 2727.27 kgm³

Therefore, the density is 2727.27 kgm³.

Hope it helps!

Why is evidence of meteorite impact rare on earth, despite the fact that meteoroids often pass into earth's atmosphere?
DENIUS [597]
The fact is your rooftop is covered with dust particles from meteorites. Outerspace is full of debris. Every day, thousands of meteorites invade our home but thanks to atmosphere for keeping us safe from them :D
When these meteorites enter our atmosphere, they experience resistance to the particles present in our atmosphere. As a result they catch fire(and eventually melts) and lose all their energy before falling on the surface. This happens with very small sized meteorites but when bigger ones enter, they surely hit the surface because they are difficult to melt.
Thanks to Jupiter for saving us from asteroids. Bigger ones rarely enters our atmosphere because of Jupiter's gravitational pull. It lures all the debris towards itself (:

Which ratio is greater than 5/8 <br><br> A)12/24 <br><br> B)3/4 <br><br> C)15/24 <br><br> D)4/12
pav-90 [236]

12/24=4x3/8x3

=4/8

4/8 is not correct ans it is less than 5/8

B) 3/4

multiply and divide it by 2 so the denominator should be equal to 8

3x2/4x2=6/8

6/8 is greater that 5/8 hence b is correct option

C)15/24=5/8 which is equalt to 5/8 hence it is not correct answer

D)4/12=1/3 it is also less than 5/8

Un auto alcanza una velocidad de 54km/hrs, en 10 segundos al partir de reposo ¿Cuál fue su aceleración?
Alborosie

Answer: 1.5\ m/s^2

Explanation:

Given

velocidad v=54\ km/h

tiempo tomado t=10\ s

Convertir km/h en m/s

\Rightarrow 54\ km/h\equiv 15\ m/s

La aceleración está dada por la tasa de cambio de velocidad

\Rightarrow a=\dfrac{v}{t}\\\\\Rightarrow a=\dfrac{15}{10}\\\\\Rightarrow a=1.5\ m/s^2

Por tanto, la aceleración es 1.5\ m/s^2
