Action and reaction are equal and opposite (Newton’s 3rd Law) so a deadly force must create a deadly reaction.
We know, U = mgh
Substitute the known values,
19.6 = m * 9.8 * 8
m = 19.6 / 78.4
m = 1/4
In short, Your Answer would be 1/4 Kg
Hope this helps!
Answer:
11772 N
Explanation:
w= weight
m= mass
g= acceleration due to gravity
The acceleration due to gravity on earth is 9.81m/s².
Substitute m= 1200 and g= 9.81 into the formula:
w= 1200(9.81)
w= 11772 N
As the gas absorbs heat, the sounds he hears become softer. This is because the pressure of the neon gas inside the container increases when the gas gets warmer, the walls of the container become tighter and stiffer, and it's harder for them to vibrate.
