Answer:
Step-by-step explanation:
4x = 38
x= 38/ 4
x = 9 1/2
A) 25% = 25/100 = 0.25
b) 18% = 18/100 = 0.18
c) 40% = 40/100 = 0.40
d) 2% = 2/100 = 0.02
e) 0.15% = 0.15/100 = 0.0015
Answer:
-3.92 N
Step-by-step explanation:
We are given that
Mass of ball=0.4 kg
Acceleration due to gravity=
Because the ball flies against to gravity
We have to find the net force acting on the ball while it is in motion.
We know that when there is no air resistance then the net force acts on the ball is equal to weight of ball.
Net force,F =mg
Substitute the values then we get


Hence, the net force acting on the ball while it is on motion=-3.92 N
I got D, but it had a decimal at the end between the 2 and the 6.
But i still got D. So D is my answer.

We want to convert this equation in terms of m, where 
While solving this problem, I instantly noticed the
in the first term of the equation. Replace that with m.

Simplifying the rest is not as obvious. Using the distributive property, we can change
to ![[7(x^2+3)]](https://tex.z-dn.net/?f=%5B7%28x%5E2%2B3%29%5D)
Do you see the "m" in here? Look again if you don't.
Now we can simplify the equation to
and this cannot be simplified further.
I'm always happy to help someone who appreciates the help! :D
