More focused mind because that is basically for math
A.
Impulse is calculated through the equation,
I = mΔv
where I is impulse, m is mass and Δv is change is velocity. Substituting the known values,
I = (6 kg)(23 m/s - 6 m/s)
I = 102 kg m/s
<em>Answer: 102 kg m/s</em>
B.
Impulse in this item is calculated by multiplying the force by the time.
I = Force / time = (29 kg m/s²)(7 s) = 203 kg m/s
<em>Answer: 203 kg m/s</em>
C.
To answer this item, we have to multiply the mass and the velocity to get the impulse and divide the answer by the time to get the force.
F = m(v)/t
Substituting,
F = (0.1 kg)(-5.69 m/s)/0.64 s
F = -0.89 N
<em>Answer: -0.89 N</em>
Well for number 2, the difference is one tells people to get ready, and one tells people it's there already.(mainly watch is a better version of a warning.
Answer:
louder sound.
Explanation:
The amplitude of a sound wave determines its loudness or volume. A larger amplitude means a louder sound
Answer:
D
Explanation:
From the formula of coulombs law F = Kq1q2/square of r, we can say the electric force is indirectly related to square of r
