We have a problem about conservation and velocity, we will find that it does affect the speed of the ball, increasing it by 1.7m/s.
There is something called momentum, which we can define as the "quantity of movement", and we can simply write as the product between velocity and mass.
The momentum is conservative, then we have conservation of momentum.
This means that when you run whit the ball in your hands, the momentum of the ball will be equal to your velocity times the mass of the ball, and this must conserve after you throw the ball.
Now with this idea in mind, this means that if you run with a velocity V, and you throw the ball with a velocity V', the velocity of the ball when it leaves your hand will be:
V + V'.
So, if you run with a velocity of 1.7m/s forward and you throw the ball (assuming in the same direction) the speed of the ball will be 1.7m/s larger than if you were to throw it standing still.

Answer:
I = 26.36 cosω t A
Explanation:
Given that
C=0.74 mF
Vrms= 82 V
Frequency ,f= 49 Hz
We know that ω = 2 π f
ω = 2 x π x 49
ω = 307.72 rad/s
As we know that voltage given as
V= Vo sinω t
\
Vo=115.96 V
V=115.96 sinω t
The current given as
I = 26362.67 cosω t mA
I = 26.36 cosω t A
This is the current at time ant time t.
The ability to attract electrons is called electronegativity.
Correct answer is D.
Explanation:
A) is not correct answer because this type of theory can not become law. Laws are properties that are same in any part of universe. Nebular theory is not correct for every part of universe.
B) is not correct answer because this theory could be replaced if some evidence show that some other theory is more likely to be correct.
C) is not correct answer because the study has been done on other nebulas in our galaxy. There are many nebulas and by obserwing them this theory was developed.
In our current view of the Universe there are 2 possible futures. One possiblity is that the Universe will come to an end in the opposite of a Big Bang called The Big Crunch. The other possibility is that we live in an Eternal Universe that will never come to end.
i hope this helps :)
