Answer:
When a tree is vigorously shaken, the branches of the tree come in motion but the leaves tend to continue in their state of rest due to inertia of rest. As a result of this, leaves get separated from the branches of the tree and hence fall down.

Answer:
It depends on the model but these are the watts of each motor
Explanation:
Un motor: 258 HP (262 CV) Dual motor: 154 kW (209 CV) y 197 kW (268 CV). Performance: 154 kW (209 CV) y 225 kW (306 CV).
Answer:
Explanation:
The remaining amount of a radioactive isotope is found as the product of the original amount by (1/2) raised to the number of half-lives elapsed. The formla is:
Where M is the remaining amoun, M₀ i s the initial amount, and n is the number of half-lives.
Here, 1/64 of the original carbon-14 remained, meaning that M/M₀ = 1/64.
Then, you can substitute in the equation and solve:
Then, 6 half-lives elapsed since the mastodon died and the remains were dated.
Then, you must multiply 6 by the <em>half-life </em>time:
- 6 × 5730 years = 34,380 years ← answer
Answer:
the velocity (magnitude and direction) of the ball) just before the collision is 
The velocity (magnitude and direction) of the ball) just after the collision is 
Explanation:
According to the law of conservation of energy;
Thus; the velocity (magnitude and direction) of the ball) just before the collision is
Since, Air resistance is negligible, and the collision is elastic.
The equation for the conservation of momentum and energy can be expressed as:
![v_f = [\frac{m_1 -m_2}{m_1+m_2}]v_i\\\\v_f = [\frac{m_{ball} -m_{block}}{m_{ball}+m_{block}}]v_i\\\\v_f = [\frac{1.6 -2.5}{1.6+2.5}]*5.144\\\\](https://tex.z-dn.net/?f=v_f%20%3D%20%5B%5Cfrac%7Bm_1%20-m_2%7D%7Bm_1%2Bm_2%7D%5Dv_i%5C%5C%5C%5Cv_f%20%3D%20%20%5B%5Cfrac%7Bm_%7Bball%7D%20-m_%7Bblock%7D%7D%7Bm_%7Bball%7D%2Bm_%7Bblock%7D%7D%5Dv_i%5C%5C%5C%5Cv_f%20%3D%20%5B%5Cfrac%7B1.6%20-2.5%7D%7B1.6%2B2.5%7D%5D%2A5.144%5C%5C%5C%5C)
