An isolated conducting sphere has a 12 cm radius. One wire carries a current of 1.0000049 A into it while another wire carries a
tatuchka [14]

Answer:

it will take for the sphere to increase in potential by 1500 V, 503.71 s.

Explanation:

The charge on the sphere after t seconds is:

q = (1.0000049 - 1.0000000) t = 0.0000049 t

The voltage on the surface is

V = k * \frac{q}{R} = k 0.0000049 t / R

solve for t

t = (R*V) / (0.0000049 k) = (0.12 * 1500) / (0.0000049 * 9e^{9}) = 503.71 s

Which of the following summarizes cellular respiration?
3241004551 [841]

The statement which summarizes cellular respiration is Oxygen reacts with glucose to produce carbon dioxide and water, and release energy.

<h3>What is cellular respiration?</h3>

Cellular respiration is the process by which food, in the form of glucose is transformed into energy within cells.

The food is prepared by the plants by the process of photosynthesis in presence of sunlight. This food is in the form of glucose.

The respiration of plants is done by breaking of glucose by absorbing oxygen. This produces  carbon- di- oxide and water along with the release of energy.

Thus, the cellular respiration is oxygen reacts with glucose to produce carbon dioxide and water, and release energy.

aliaa is skating down a ramp. the wheels on her skateboard have diameters of 60 \text{ mm}60 mm60, start text, space, m, m, end
GarryVolchara [31]

The total distance traveled by Aliaa using her skateboard for 20 revolution of the wheels is equal to 3770 millimeters.

<u>Given the following data:</u>

Diameter of skateboard = 60 mm.

Number of revolution = 20 revolutions.

Radius = diameter/2 = 60/2 = 30 mm.

<h3>What is distance?</h3>

Distance can be defined as the amount of ground covered (traveled) by a physical object over a specific period of time and speed, regardless of its direction, starting point or ending point.

For one revolution of the wheels, the distance traveled by Aliaa using her skateboard is given by:

Distance = 2πr

Distance = 2 × 3.142 × 30

Distance = 188.5 mm.

Therefore, the total distance traveled by Aliaa using her skateboard for 20 revolution of the wheels is given by:

Distance = 188.5 × 20

Distance = 3770 millimeters.

nevsk [136]

Answer:

A. 2.2*10^-2m

Explanation:

Using

Area = length x L/ uo xN²

So A = 0.7m * 25 x 10^-3H /( 4π x10^-7*

3000²)

A = 17.5*10^-3/ 1.13*10^-5

= 15.5*10^-2m²

Area= π r ²

15.5E-2/3.142 = r²

2.2*10^2m
