Answer: PE = 800j, KE = 800J
Explanation:
To calculate the potential energy, we use the formula
Potential Energy = Mgh
M = 20kg, g = 10m/sˆ2 , h = 4m
=20 × 10 × 4
=800J
At the maximum height S = 4 and the initial velocity u = 0 The acceleration g = 10m/sˆ2
Using the third equation of motion
vˆ2 = uˆ2 + 2as
= 0ˆ2 + 2 × 10 × 4
vˆ2 = 80
Kinetic Energy (KE) is given by
KE = ½ mvˆ2
= ½ × 20 × 80
=800J
Answer:
The primary benefit of guaranteeing the right to a jury trial in criminal and civil cases is Option B: All of these
Explanation:
The main benefit of guaranteeing the rights to a jury trial in case of criminal and civil defendants unnecessary. They also have right to lawyer and a right to have an impartial jury. Also, in case of criminal prosecutors, they have a right to know the accusers and what kind of charges are being against them.
This helps in bringing a lot of confidence in the verdict as it is unanimous. Thus, all the statements A, C and D are true. Thus, answer is "All of these".
Hello. The full question is: As a student what can you to do save not only a particular system but the earth itself?
Answer and Explanation:
The land is the responsibility of all its inhabitants, even us students. It often seems that we cannot do anything to save it from so much exploitation, but the truth is that we can do a lot, even in our limitation. Among the things we can do are:
Reduce the waste and waste we generate. Mainly from materials made of plastic that have a strong impact on nature and take a long time to be degraded.
We can reuse and recycle as much as we can. This is very important because it allows us, once again, to reduce waste and pollution that degrade the environment and cause problems for all elements of the ecosystem.
We can also not waste water, as well as avoid the pollution of water bodies in our community.
We can educate ourselves and educate people close to us about the problems of pollution and environmental imbalance, in addition to reinforcing the importance of taking care of the planet that is our home.
The purpose of the Second Continental Congress was to let the American colonies present the complaints to the British.
