The fig below explains it.
4. A truck was detected exceeding the posted
1 answer:
<u>Answer:</u>
<em>The truck is going 40 km/h faster than the speed limit. </em>
<u>Explanation:</u>
The fixed speed limit = <em>60km/h</em>
distance travelled by the truck = <em>10 km</em>
time taken <em>t=6 minutes</em>
we have convert 6 minutes into hour
<em>1 hour=60 minutes </em>
<em>1 minute=1/60 hour </em>
<em>6 minute=6/60 hour=1/10 h </em>
Speed is obtained by dividing distance covered by time.
<em> speed = distance/time = =100 km/h
</em>
<em>difference between the speed of the car and the speed limit</em>
<em>=100-60 = 40km/h </em>

Answer:
Explanation:
The density of a material is given by:
(1)
Where:
is the mass of the cube
is the volume of the cube
Now, the volume of a cube is equal to the length of its edge to the power of 3:
(2)
If we know , the volume of this cube is:
(3)
Substituting (3) in (1):
(4)
This is the density of the cube
