Mary takes a sightseeing tour on a helicopter that can fly 450 miles against 15 mph headwind in the

1) PE=mgh
mass 50 kg; height 3; g 9.81
50×3×9.81=1471.5 J

2. The student is opposing gravity force so 
Fgrav=m×g
50 × 9.81= 490N
Work=force×displacement
490×3=1470J(this should always be the same as the potential energy)

3.Power=work×time
4410 W=1470×3

4. Greater than: power is dependent on work, work is dependent on force, force is dependent on weight, 

sure

160

Step-by-step explanation:

360 seconds?

Step-by-step explanation:

90 mph

Step-by-step explanation:

Against wind DATA:

distance = 600 miles ; time = 5 hrs. ; rate = 600/5 = 120 mph

With wind DATA:

distance = 600 miles ; time = 2 hrs ; rate = 600/2 = 300 mph

Equations:

p + w = 300

p - w = 120

2p = 420

p = 210 mph (speed of the plane in still air)

Since p+w = 300, w = 300-210 = 90 mph (speed of the wind)

A. “Together, after 50 years of taking power away from the hands of the people in their states and local communities, we have started returning power and resources to them.”

Explanation:

"New Federalism" refers to a political philosophy that tries to bring back the power from the national government to the people. Under the governance of Richard Nixon, the 37th President of the U.S.A., who supported the New Federalism, power was gradually restored to the state and local governments. These allowed them to take effective measures in using the federal money according to the problems or issues in their own states or local communities.

Among the choices mentioned, choice A best reflects the ideals of the New Federalism. This allows proper management in the government and less occurrence of fraud.

So, this explains the answer.

tysm!!!

Step-by-step explanation:

have a pretty day :)

V = 160mph

Step-by-step explanation:

We need to start from the formula of speed: V=d/t

We have two travels, with and against the wind, both done in the same time.

Clearing t from the formula, we will have: t=d/V2

450miles/V-35mph (speed of the wind is subtracted)

702miles/V+35mph (speed of the wind is subtracted)

Now, we find V:

450miles/V-35mph = 702miles/V+35

450*V+35 = 702*V-35

450V+15,750 = 702V-24,570

702V-450V = 15,750 + 24,570

252V = 40,320

V = 40,320/252

V = 160mph

[B] Only State A and State B can take action against Bill.

Explanation:

This is because the whole details of the transaction took place between State A and State B. This is why the states involved can take action against Bill. If not, then all the States would have had the right to take action against Bill.

This analysis validates that Only State A and State B would be able to take action against Bill.

Sorry idk, I just need points to ask my question
