<span>Nonliving things also have unlimited duration of existence. While living things die and decompose, nonliving things such as rocks, mountains, air and water have existed for millions of years. They may grow, but they do so only by accretion, which is the process of growth by accumulating added layers of matter.</span>

Consider a disk of radius 4.9 cm, having a uniformly distributed charge of +6.1 μC. The value of the Coulomb constant is 8.98755
gayaneshka [121]

Answer:

the electric field is 42.8×10^6 N/C

Explanation:

let k be the coulomb constant, Q be the charge distribution , R be the radius of the disk and x be the distance from the center.

k = 8.98755×10^9 N×m^2/c^2

Q = 6.1×10^-6 C

R = 4.9×10^-2 m

x = 3.1×10^-3 m

A 2.50 gram rectangular object has measurements of 22.0 mm, 13.5 mm, and 12.5 mm. what is the object's density in units of g/ml?
Zinaida [17]
G/mL is equivalent to g/cm^3, so we first convert the dimensions into cm:
2.20 cm, 1.35 cm, and 1.25 cm
Then the total volume is: V = lwh = 3.7125 cm^3
To get the density, we divide mass by volume: 2.50 g / 3.7125 cm^3 = 0.6734 g/cm^3 = 0.6734 g/mL

1. What did you observe about the magnitudes of the forces on the two charges? Were they the same or different? Does your answer
Aloiza [94]

Answer:

Following are the solution to the given question:

Explanation:

Its strength from both charges is equivalent or identical. The power is equal. And it is passed down

F=\frac{kq_1q_2}{r^2}

Therefore, the extent doesn't rely on the fact that charges are the same or different. Newton's third law complies with Electrostatic Charges due to a couple of charges. They are similar in magnitude, and they're in the other way.

|F_{12}| = |F_{21}|

An automobile having a mass of 2000 kg deflects its suspension springs 0.02 m under static conditions. Determine the nafural fre
alexandr1967 [171]

Answer:Frequency = 3.525 Hertz

Explanation:In static equilibrium, kd =mg

Where k= effective spring constant of the spring.

mg= The weight of the car.

d= static deflection.

Therefore, w =SQRTg/d

w = SQRT 9.81/0.02

w= 22.15 rad/sec

Converting to Hertz unit for frequency

1 rad/s = 0.1591

22.15rad/s=?

22.15 × 0.1591= 3.525 hertz

A sound wave has a wavelength of 3.0m. The distance from a compression center to the adjacent rarefaction center is:
antiseptic1488 [7]

Answer:

3 m

Explanation:

It is given that,

The wavelength of a sound wave is 3 m.

We need to find the distance from a compression center to the adjacent rarefaction.

We know that, sound is a longitudinal wave. It travels in the form of compression and rarefaction.

Also, the distance between compression center to the adjacent rarefaction centre is called wave. Hence, the required answer is 3 m.
