Assuming 84.0% efficiency for the conversion of electrical power by the motor, what current must the 13.0-V batteries of a 716 k
tino4ka555 [31]

Answer:

\mathbf{ current(I) =1766.67 \ A}

Explanation:

Given that:

The air resistance and friction = 700 N

The gravity caused force = 716 × 9.8 = 7016.8

Total force = (7016.8 + 700) N

Total force = 7716.8 N

∴

13 \times  current(I) \times 0.84 = \dfrac{7716.8 \times 300}{2 \times 60}

current(I) \times 10.92= 19292

current(I) = \dfrac{19292}{10.92}

\mathbf{ current(I) =1766.67 \ A}

Describe each of the following as a physical or chemical property. a. Neon is a colorless gas at room temperature.b. Apple slice
Cloud [144]

Answer: Neon is a colorless gas at room temperature: Physical property

At room temperature, mercury is a liquid: Physical property

Apple slices turn brown when exposed to air: Chemical property

Phosphorus will ignite when exposed to air: Chemical property

Explanation:

Physical property is defined as the property of a substance which becomes evident during physical change in which there is alteration in shape, size etc. No new substance gets formed during physical change.

Example:  Neon is a colorless gas at room temperature

At room temperature, mercury is a liquid.

Chemical property is defined as the property of a substance which becomes evident during chemical change in which a change in chemical composition takes place. A new substance is formed in these reactions.

Example: Apple slices turn brown when exposed to air: It undergoes oxidation which is a chemical change

Phosphorus will ignite when exposed to air: It undergoes oxidation which is a chemical change
