Describe in your own words a situation where chemical energy is transformed to potential energy.

Answer:

repel each other

Explanation:

The magnitude of the charge of an electron is called... ... If a positively-charged glass rod is suspended so that it turns easily and another positively-charged glass rod is brought close to it, the two rods will... Repel each other.

The frictional force opposes the forward motion of the crate. The coefficient of static friction is 0.2.

Using the formula;

Fa = - Ff + mgsinθ

but Ff = μsFN and N = mgcosθ

Hence;

Fa = mgsinθ - μsmgcosθ

μsmgcosθ = mgsinθ - Fa

μk =  mgsinθ - Fa/mgcosθ

μk =  coefficient of static friction = ?

Fa = horizontal force = 100N

m = mass = 30.6 kg

θ = angle = 30°

g = acceleration due to gravity = 10 m/s^2

Substituting values;

μk =  [(30.6 × 10) sin 30°] - 100 / (30.6 kg × 10) cos 30°

μk = 153 - 100/265

μk = 0.2

b. Calculate the potential energy, the kinetic energy, and the total energy of the car as it leaves the cliff.

c. Make a graph displaying the kinetic, gravitational potential, and total energy of the car at each 10 m

increment of height as it drops

Explanation:

The potential energy of the car at that position is 10.6 x 10⁵ J.

Potential energy of an object is defined as the energy acquired by the object by virtue its position.

Here,

Mass of the car, m = 1200 kg

Speed of the car, v = 29 m/s

Height of the cliff, h = 90 m

Therefore,

Potential energy of the car, PE = mgh

PE = 1200 x 9.8 x 90

PE = 10.6 x 10⁵ J

Hence,

The potential energy of the car at that position is 10.6 x 10⁵ J.

C. 10 Coulombs

Part 2

A. The strength of the magnet increased as the amount of current increased.

Explanation:

1. When a voltage is applied to these plates an electrical current flows charging up one plate with a positive charge with respect to the supply voltage and the other plate with an equal and opposite negative charge.

If the capacitors are connected by a conductor they must have equal potentials. If their charges are not +/- Q there will be a potential difference and charges will flow until they are +/- .

2. Based upon the results of the experiment which is graphed, an increase in current increases the number of paperclips picked up. The increase in current produced a stronger magnetic field from the electromagnet created. The ability to pick up paperclips testifies to the strength of the magnet and this strength is because of the current emitted to the coils which in turn magnetizes the nail

Explanation:

Volume of the air bubble, V1=1.0cm3=1.0×10−6m3

Bubble rises to height, d=40m

Temperature at a depth of 40 m, T1=12oC=285K

Temperature at the surface of the lake, T2=35oC=308K

The pressure on the surface of the lake: P2=1atm=1×1.103×105Pa 

The pressure at the depth of 40 m: P1=1atm+dρg

Where,

ρ is the density of water =103kg/m3

g is the acceleration due to gravity =9.8m/s2

∴P1=1.103×105+40×103×9.8=493300Pa

We have T1P1V1=T2P2V2

Where, V2 is the volume of the air bubble when it reaches the surface.

Hello, Rotting, burning, cooking, and rusting are all further types of chemical changes because they produce substances that are entirely new chemical compounds. For example, burned wood becomes ash, carbon dioxide, and water. When exposed to water, iron becomes a mixture of several hydrated iron oxides and hydroxides.

Explanation:

What does auxiliary heat mean on a Honeywell thermostat.

What does aux heat mean on a Honeywell system? Short for auxiliary heat, this system is designed to heat your home up quickly instead of waiting for the cold heat pump on the exterior of your home. Unfortunately, using the auxiliary heat is significantly more expensive than using your heat pump.

Aux on the thermostat stands for auxiliary heat. Auxiliary heat is the electric heat strip in your air handler that is supplemental heat. Emergency heat is the same thing as auxiliary heat. Auxiliary heat/ Emergency heat help the heat pump keep up when cold outside or the temperature differential on the thermostat is large.
