Answer:
a.)
b.) 5 blocks
Explanation:
Let's find the volume of the metal block:
Now, let's find the volume of the smaller blocks:
So, one small block has a volume of 8cm. If the volume of the larger block is 40cm, we can fit a total of 5 smaller blocks into the larger block, meaning it will make up the same volume.
<span>The answer would be Vestibular Senses.
Consciousness of body equilibrium and movement are checked by the vestibular
system. The vestibular senses (the feelings of
body rotation and of attraction and gravity) ascend in the inner ear; the sense
organs are the hair cells that give off signals done in the auditory nerve.</span>
Mass of the car = 1200 kg
Mass of the truck = 2100 kg
Total mass of car and truck = 2100 + 1200 = 3300 kg
Since, the car pushes the truck. Hence, they will move together and will have same acceleration.
Let the acceleration be a.
According to Newton's second law:
F(net) = ma
F = 4500 N
4500 = 3300 × a
a = 1.36 m/s^2
Let the force applied by the car on truck be F.
F = F(net) on the truck
F = ma
F = 2100 × 1.36
F = 2856 N
Hence, the force applied by the car on the truck is 2856 N
