Answer: the answer is storing properly in refrigeration.
Explanation:
Answer: Accelaration is 2.77 m/s*s
<h2 />
Explanation:
V0=0km/h=0m/s
V1=100 km/h=27.7 m/s
t=10s=
Use equation for accelaration : a=(V1-V0)/t
a=(0m/s-27.7m/s)/10s
a=-27.7s/10s
a=2.77m/s*s
The answer should be B. Fault.
Answer:
3- A ball of mass 0,50 kg falls and hits the floor at 10m/s,
It rebounds at speed 8.0 m/s, as shown.
before collision
after collision
10 m/s
8 m/s
The collision between the ball and the floor lasts for 0.50 s.
What is the average force acting on the ball during the collision?
The older students should be able to complete the puzzle in a shorter amount of time than the younger students
