Answer:

The total mechanical energy is 0.712 J.

Step-by-step explanation:

A blue 573 g mobile is moving on a metal rail. If on the mobile, the spring exerts a force to the right of modulus 0.85 N and in the indicated position the kinetic energy of the mobile-spring system is 0.47 J and its elastic potential energy is 0.242 J. Determine the mechanical energy of the system mobile-spring in the position shown as indicated in the figure.

The total mechanical energy is given by the sum of the kinetic energy and the potential energy.

Kinetic energy = 0.47 J

Potential energy = 0.242 J

The total mechanical energy is

T = 0.47 + 0.242 = 0.712 J

Anyone know what the answer is for this
Anika [276]

Answer:

x^9

Step-by-step explanation:

If we have x^2 * x^3 we have (x * x) * (x * x * x) = x * x * x * x * x = x^5 which demonstrates that x^a * x^b = x^(a+b), 4 + 5 = 9

How far is the little guy from the flagpole (assuming a right angle between the flagpole and the ground)? Explain how you got yo
Naya [18.7K]

Answer:

b = 9 ft

Step-by-step explanation:

Pythagorean Theorem:

a^2 + b ^2 = c^2

Given:

a = 12

b = ?

c = 15

Plug in values:

12^2 + b^2 = 12^2

Solve for b^2:

b^2 = 15^2 - 12^2

b^2 = 225 - 144

b^2 = 81

Take square root of both sides to find b:

sqrt(b^2) = sqrt(81)

b = 9


Hope this helps! :)

Plsss HELP ANYONE PLSSS !
Talja [164]

Answer:

can be fourth one cause it starts at 2 on y axis. ( fourth option)

Step-by-step explanation:

can't be the first one cause it starts at origin

can't be second one cause it starts at -2 on x axis

can't be third on cause it starts on 2 on x axis

can't be fifth cause it starts on -2 on y axis.
