A fifth-grade teacher has provided the students with a discovery science lesson. The students worked in groups to create landfor

larisa [96]

Answer: By providing opportunity to promote further questioning and thinking.

Explanation: In discovery Science, the major thing we do is to think about what we are discovering, then ask questions which our discoveries will solve. Because the teacher has given a platform where each group should think about what they have discovered, and then share it with the rest of the class. Any member of the class has an opportunity to ask question, about what the group has discovered. This makes it a discovery Science, because thinking and questioning has been involved.

if a woman in a plane waiting to parachute is 3,940m high and has a mass of 70kg,what is her gravitational potential energy (gpa

LiRa [457]

Answer:

$\boxed {\boxed {\sf 2,702,840 \ Joules }}$

Explanation:

The gravitational potential energy can be found using the following formula

$E_p=m*g*h$

Where m= mass, g= gravitational acceleration, and h = height.

We know the the mass of the woman is 70 kilograms and the height is 3,940 meters

If we assume this parachute is on Earth, then the gravitational acceleration is 9.8 m/s²

$m= 70 \ kg \\h= 3,940 \ m \\g= 9.8 \ m/s^2$

Substitute the values into the formula.

$E_p= (70 \ kg) (9.8 \ m/s^2)(3,940 \ m)$

Multiply the first two numbers first.

$E_p=686 \ kg*m/s^2 (3,940 \ m )$

1 kg*m/s² is equal to 1 Newton. Therefore, the first number (686 kg*m/s²) is also equal to 686 Newtons

$E_p=686 \ N (3,940 \ m)$

Multiply again.

$E_p= 2702840 \ N*m$

1 Newton meter is equal to 1 Joule. So, our answer of 2702840 N*m is equal to 2702840 J

$E_p=2702840 \ J$

The potential energy of the women is 2,702,840 Joules

Which best describes the Impact of the independence agencies on the executive branch

schepotkina [342]

Independent agencies such as the CIA or FCC operate outside of the President's immediate sphere of influence, but still are under executive scrutiny, therefore the answer is that they "cause the executive branch to influence many aspects of life in the United States."
