2. random motion in vertical direction
Atoms have an overall charge that is neutral because atoms have equal number of positive protons and negative electrons thus they cancel each other out. This always true for atoms that are stable and in equilibrium.
Answer:
The speed will be "1.06 m/s".
Explanation:
The given values are:
Momentum,
m1 = 244 g
m2 = 45.2 g
On applying momentum conservation

The approximate acceleration of the car would be <span>3.00
</span>How? We have to use the formula to find the velocity.
v = d/t = 120/6.32
v = 19
Then plug the factor into the acceleration formula to find the acceleration:
a = v/t = 19/6.32
a = 3.00
So, the approximate acceleration of the car would be 3.00
Answer:
1.1x10^-2N
Explanation:
We have the change in momentum as
P = 0.3(4.5+12)g.mph
= 0.3x0.447x(4.5+12)x10^-3
Then the force that is exerted will be
F = p/∆t
∆t = 0.2
= 0.3x0.447x(4.5+12)x10^-3/0.2
= 0.1341x16.5x10^-3/0.2
= 1.1x10^-2
Therefore the force that was exerted is equal to 1.1x10^-2
