Two conducting spheres are each given a charge Q. The radius of the larger sphere is three times greater than that of the smalle
padilas [110]

Answer:

Explanation:

If E₀ is the electric field outside the smaller sphere and r is the radius of larger sphere.

E₀ = kQ/r²

The radius of the larger sphere is 3r and the charge on both sphere is same then the electric field outside the larger sphere is given as

E = kQ/(3r)² = kQ/9r² = 1/9 (kQ/r²)= 1/9 x E₀

hence the correct option is e.

A train travels 8.81 m/s in a -51.0° direction.
Amiraneli [1.4K]

The displacement of the train after 2.23 seconds is 25.4 m.

<h3>Resultant velocity of the train</h3>

The resultant velocity of the train is calculated as follows;

R² = vi² + vf² - 2vivf cos(θ)

where;

  • θ is the angle between the velocity = (90 - 51) + 37 = 76⁰

R² = 8.81² + 9.66² - 2(8.81 x 9.66) cos(76)

R² = 129.75

R = √129.75

R = 11.39 m/s

<h3>Displacement of the train</h3>

Δx = vt

Δx = 11.39 m/s x 2.23 s

Δx = 25.4 m

Thus, the displacement of the train after 2.23 seconds is 25.4 m.

The change in the angle of circular motion is analogous to ____ in linear motion
snow_lady [41]

The change in the angle of circular motion is analogous to <u>linear velocity</u> in linear motion

<u>Explanation:</u>

We define angular velocity ω as the rate of change of an angle. The greater the rotation angle in a given amount of time, the greater the angular velocity. angular velocity refers to how fast an object rotates or revolves relative to another point, i.e. how fast the angular position or orientation of an object changes with time.

The units for angular velocity are radians per second (rad/s). Angular velocity ω is analogous to linear velocity v. Linear velocity is the measure of “the rate of change of displacement with respect to time when the object moves along a straight path.” It is a vector quantity.

Why some air masses are cool, cold, warm, and hot as well as moist or dry?
DENIUS [597]

Answer:

Explanation:

Often times, the property of air masses is a function of where they originate from especially with respect to latitude.

An air mass is certain amount of air with some unique set of temperature and vapor component.

  • Air masses differs from places to places based on where  they originate.
  • Continental air masses are usually dry and cold because there is little to no water on a land mass.
  • Air masses that originates from the surface of the ocean are predominantly moist.
  • In polar regions, the air mass is cold.
  • Around the tropics, they are usually warm due to insolation here.
