Answer: false
Explanation:
While kilograms are the unit used to measure body mass, the device used is a scale.

Answer:
t = 1,144 s
Explanation:
The simple pendulum consists of an inextensible string with a mass at the tip, the angular velocity of this is
w = √( L / g)
The angular velocity is related to the frequency and period
w = 2π f
f = 1 / T
w = 2π / T
Let's replace
2π / T = √ (L / g)
T = 2π √ (g / L)
Let's calculate
T = 2π √ (9.81 / 18.5)
T = 4,576 s
The definition of period in the time it takes the ball to come and go to a given point (a revolution) in our case we go from the end to the middle point that is a quarter of the path
t = T / 4
t = 4,576 / 4
t = 1,144 s
Answer:
Explanation:
Let's call the large box "1" and the smaller box "2". The equation for this works so that momentum is conserved, as the Law states.
![[(m_1v_1+m_2v_2)]_b=[m_1+m_2)v]_a](https://tex.z-dn.net/?f=%5B%28m_1v_1%2Bm_2v_2%29%5D_b%3D%5Bm_1%2Bm_2%29v%5D_a)
That says that the momentum of the larger box plus the momentum of the smaller box before the collision has to equal the momentum of the combined masses since they stick together. Filling in:
[(4(12) + 2(0)] = [(4 + 2)v] and
48 + 0 = 6v so
v = 8 m/s to the right
