Answer:
y=8
Explanation:
every time you multiply x by 3 you divide y by 3.
x=2, multiply it by 3: x=6
y=24, divide it by 3: y=8
Answer:
see explanation
Explanation:
by my calculations, i believe it may be because they have to pretend to be in space.
Answer:
Acceleration is increasing or decreasing speed or changing direction, whereas velocity is how much distance you cover in a given amount of time.
Explanation:
I hope this helps :D
Answer:
5.886 J
Explanation:
Given:
The mass of the book is, 
kg
Height of lift is, 
m
Acceleration due to gravity is, 
m/s²
Now, gain in gravitational potential energy is a function of change in position and is given as:
Here, 
is the change in gravitational potential energy.
Plug in 0.5 kg for 
, 9.81 for 
and 1.2 for 
. Solve for
Therefore, the gain in gravitational energy of the book is 5.886 J.
Answer:
A bowling ball stored on a high shelf has more potential energy
A base ball on the same shelf should rather fall on my head
Explanation:
Potential energy =mgh where m= mass, g= gravitational force and h is height
The bowling ball is bigger and heavier than the base ball
which means more mass . The remaining parameters are constant.
This means the bowling ball has more potential energy.
Since the base ball is lighter then it’s preferable to land on someone’s head due to the lesser force it will expert and lesser pain too.
