Answer:
Explanation:
Let mass of cart be m₁ and m₂
m₁ + m₂ = 1.5 kg
At the time of release , their momentum will be conserved
m₁ v ₁ = m₂ v₂
m₁ v ₁ = (1.5 - m₁ ) x 2 v₁
m₁ = 3 - 2m₁
3m₁ = 3
m₁ = 1 kg
m₂ = .5 kg
Answer:
The main facts about palm oil
<h2> Here are the main facts why palm oil plantations are harming the environment: They release massive amounts of CO2 in the air as rainforests are cleared. Rainforests' soils hold about 45% of the world's terrestrial carbon, cutting them down is like releasing a carbon bomb.</h2><h3>The production of palm oil can result in land grabs, loss of livelihoods and social conflict, and human rights are often violated on plantations. The resulting conflicts have had a significant impact on the social welfare of many. Read more. Palm oil is one of the most profitable land uses in the tropics.</h3>

In this question the options are missing; here are the options:
What was the dependent variable in Drew's experiment?
A. The depth at which the algae were found
B. The sky conditions on a particular day
C. The amount of algae measured
D. The lake that was being observed
The answer to this question A. The depth at which the algae were found
Explanation:
In an experiment, it is common there are at least two factors or variables. Additionally, the variable that is modified by others or that depend on others is always the dependent variable.
In the case of the experiment presented, there are two main factors: sky conditions and depth at which algae can be found. From these, the dependent factor is the depth because this depth changes with the sky condition or depends on the sky conditions. Also, the dependent variable is always the factor being studied, for example, in this case, Drew's focus is to study how the location of algae in terms of depth changes.
Answer:
7.66 m/s²
Explanation:
The following data were obtained from the question:
Initial velocity (u) = 0 mph
Final velocity (v) = 60 mph
Time (t) = 3.5 s
Acceleration (a) =.?
Next, we shall convert mile per hour (mph) to metre per second (m/s). This can be obtained as follow:
Recall:
1 mph = 0.447 m/s
Initial velocity (u) = 0 mph
Initial velocity (u) = 0 × 0.447 = 0 m/s
Final velocity (v) = 60 mph
Final velocity (v) = 60 × 0.447 = 26.82 m/s.
Finally, we shall determine the acceleration of Rihanna as follow:
Initial velocity (u) = 0 m/s
Final velocity (v) = 26.82 m/s.
Time (t) = 3.5 s
Acceleration (a) =.?
a = (v – u) /t
a = (26.82 – 0) / 3.5
a = 26.82 / 3.5
a = 7.66 m/s²
Thus, the acceleration of Rihanna is 7.66 m/s²
Answer:
The distance the piece travel in horizontally axis is
L=3.55m
Explanation:
Now the angular velocity is the blade speed so:
assuming no air friction effects affect blade piece:
time for blade piece to fall to floor
Now is the same time the piece travel horizontally
blade piece travels HORIZONTALLY = (24.5)(0.397) = 9.73 m ANS
