Answer:

Bridget is transferring energy to the bicycle.

The bicycle is using energy to do work.

Bridget has kinetic energy.

The bicycle has potential energy.

The bicycle has mechanical energy.

Explanation:

Energy can be transformed from one form to another. A body possess kinetic energy due to virtue of its motion. Potential energy is possessed by a body due to virtue of its position. mechanical energy is the sum of potential energy and kinetic energy. Nuclear energy is produced when atoms split or two atoms fuse together.

When Bridget is riding bicycle up a hill. Energy involved is both kinetic energy due to motion and potential energy due to gain in height up the hill. Bridget is pedaling, hence he is transferring energy to the bicycle. Bridget is in motion along with the bicycle. Hence, both Bridget and Bicycle have kinetic energy and potential energy. We can say both have mechanical energy. Thus correct options are:

Bridget is transferring energy to the bicycle.

The bicycle is using energy to do work.

Bridget has kinetic energy.

The bicycle has potential energy.

The bicycle has mechanical energy.

Air is enclosed in a syringe at room temperature. The end is the pushed so the air only fills a 1/3 of the length of the syringe
borishaifa [10]

Answer:

A) Does not change

B) Decrease

C) Increasing

D) Increasing

Explanation:

When it pushes it's volume is reduced by 1/3 because it's Area is constant there for only volume is decreased. Then the number of molecules don't change

A) don,t change

B) Decreases

C) Density is increased because it mass doesn't change. there for

Mass = Density * Volume

When Volume is decreasing to keep mass constant Density will be increased.

D) Pressure is increased according to the boil's law. it says that for fixed mass and fixed temperature pressure is inversely proportional to the volume. then volume decrease pressure increase

If you were to make a three-dimensional model of magnetic force using a magnet and magnetic field lines, which two characteristi
kkurt [141]

Answer:

- the Magnetic field lines will spread out of the north end of the magnet.

- the magnetic fields will three-dimensional and resemble a bubble.

Explanation:

- Usually, when drawing magnetic field lines, we start outwardly from the North pole to the South Pole. This same direction is also prevalent on the Earth due to the fact that the Earth functions as a giant magnet. Thus, one characteristic of the model is that the Magnetic field lines will spread out of the north end of the magnet.

- Another thing is that Magnetic field forces are usually driven as a result bubble like configuration which affects the objects that are in such a configuration. Thus, another characteristic of the model is that the magnetic fields will three-dimensional and resemble a bubble.

A sphere of radius 6cm is moulded into a thin cylindrical wire of length 32cm. Calculate the radius of the
suter [353]

Answer:

4/3 pi R^3 = pi r^2 L     equating volume of sphere and wire

r = (4 R^3 / 3 * L)^1/2      solving for radius of wire

r = (4 * 6^3 / 3 * 32)^1/2

r = 9^1/2 cm = 3 cm = .03 meters

A generator connected to an RLC circuit has an rms voltage of 140 V and an rms current of 31 mA. Part A
vredina [299]

Answer:

53.06 ohm

Explanation:

We have given the rms voltage V =140 V

And the rms current i=31 mA

So the impedance Z=\frac{V}{i}=\frac{140}{3\times 10^{-3}}=46.666kohm

Resistance is given as R = 3 kohm

And capacitive reactance X_C=6.5kohm

We know that Z=\sqrt{R^2+(X_L-X_C)^2}

46.666=\sqrt{3^2+(X_L-6.5)^2}

Squaring both side 2177.1556=9+(X_L-6.5)^2

(X_L-6.5)^2=2168.155

(X_L-6.5)=46.5634

X_L=53.063ohm
