In technical terms, every coil of wire increases the "magnetic flux density" (strength) of your magnet.
So it's A (magnetic field increase)
Answer:
You're four sentences should include about how the roller coaster has the most potential energy at the top of the track, and the opposing energy, "kinetic" has the most kinetic energy when going down the hill.
Explanation:
Kinetic - In-Motion.
Potential - Gathering Energy to go into Motion.

Answer:
112.58
Explanation:
The Coefficient of Performance of any system is denoted by COP=Q/W, where Q is the useful heat supplied or removed and W is the work required by the system. According to the first law of thermoddynamics Qh= Qc + W, where Qh is the heat transfered to the hot reservoir and Qc is the heat collected from the cold reservoir. Substituting the values for W and apllying the limitation for maximum theoretical efficiency we end up with the eqution shown below.
The Coefficient of Performance of air conditioner or COP is denoted by
COP(cool) = Tc/(Th- Tc)
where Tc: the lowest temperature
Th: the highest temperature
converting the values to Kelvin and adding them in the above equation
COP(cool) = (25+273)/((34+273)-(25+273))
= 298/(307-298)
= 298/9 = 33.11
From the question, it is stated that COP=SEER/3.4
hence, SEER= COP * 3.4
SEER= 33.11 * 3.4 = 112.58
Gravitational Potential Energy, GPE = mgh
Where m is your mass in kg, g is acceleration due to gravity = 9.8 m/s², and h is the height in m.
The only value that be controlled here is the height h. The mass is constant, and acceleration due to gravity at that place is constant.
But h can be varied.
Hence to increase the gravitational potential energy between yourself and Earth is to increase the height h.
This can be done by climbing up a table, or climbing up a building through the stairs, or by using a lift.
Answer:
0.0768 revolutions per day
Explanation:
R = Radius
= Angular velocity
As the mass is conserved the angular momentum is conserved
Moment of intertia for solid sphere
Moment of intertia for hollow sphere
Dividing the moment of inertia
From the first equation
The angular velocity, in revolutions per day, of the expanding supernova shell is 0.0768 revolutions per day
