Answer:N=0
Explanation:
Given


both blocks experiencing free fall so net weight of block during free fall is zero thus there is no normal reaction between them.
N=0
Answer:
Organelles
Explanation:
I learned this in science.
It's important because you have to know when to make it go faster or else you might not be able to go upside down or in a circle
Answer:
The kinetic energy of the bullet is 5.4 × 10³ J
Explanation:
Hi there!
The equation of kinetic energy is the following:
KE = 1/2 · m · v²
Where:
KE = kinetic energy.
m = mass of the bullet.
v = speed of the bullet.
Let´s convert the mass unit to kg so that our result is in Joules:
64 g · ( 1 kg / 1000 g) = 0.064 kg
Then, the kinetic energy will be the following:
KE = 1/2 · 0.064 kg · (411 m/s)²
KE = 5.4 × 10³ J
Yes because it helps them locate their position and direction
