Answer:

**Answer:**

**U. With no variation.**

**Explanation:**

Note- since temperature remains constant when pressure becomes twice and volume becomes half, and internal energy of ideal gas is function of only temperature so it remains constant. The internal energy is independent of the variables stated in the exercise.

A 2-C charge experiences a force of 40 N when put at a certain location inspace. The electric field at that location is a. 2 N/C.b. 20 N/C. c. 30 N/C. d.40 N/C. e. 60 N/C.

An element emits light at two nearly equal wavelengths, 577 nm and 579 nm If the light is normally incident on a diffraction grating with 2000 lines/cm., what is the distance between the 3rd order fringes of the two wavelengths on a screen 1 m from the grating?

Two parallel wires I and II that are near each other carry currents i and 3i both in the same direction. Compare the forces that the two wires exert on each other. A. The wires exert equal magnitude attractive forces on each other. B. Wire I exerts a stronger force on wire II than II exerts on I.C. Wire II exerts a stronger force on wire I than I exerts on II. D. The wires exert equal magnitude repulsive forces on each other. E. The wires exert no forces on each other.

A parallel-plate capacitor is charged and then disconnected from the battery. By what factor does the stored energy change when the plate separation is then doubled?

**Answer:**

The description is outlined throughout the clarification section following, and according to the given word.

**Explanation:**

- Throughout the 1960s, Sarnoff Mednick created the RAT as a tool used for testing imaginative convergent thought. Through each RAT test query lists a set of terms, which demands that we have a single additional term that will tie any of the others around.
- Those other words may also be related in something like a variety of ways, such as through creating a compound word or perhaps a semantic connexon.

**Answer:**

The idea that population growth is potentially exponential while the growth of the food supply or other resources is linear.

**Explanation:**

The particle reach its minimum velocity at time **1.06 sec.**

The function is given as

x=5t^3-8t^2+12

Differentiating the above equation with respect to time, to obtain the velocity

dx/dt=v=15t^2-16t

For maximum and minimum values, put dx/dt=0

15t^2-16t=0

On solving the equation, t=0, 1.06

Therefore at time** t=1.06 sec,** the particle has the minimum value of velocity.

The particle reaches its minimum velocity at **t = 0 s or t = 16/15 s**

**Acceleration** is rate of change of velocity.

*a = acceleration ( m/s² )*

*v = final velocity ( m/s )*

*u = initial velocity ( m/s )*

*t = time taken ( s )*

*d = distance ( m )*

Let us now tackle the problem!

__Given:__

To find the velocity function, we will derive the position function above.

Next to calculate the time to reach its minimum speed, then v = 0 m/s

b. 2/pi

c. 2

d. (2)^1/2

**Answer:**

the answers the correct one is a 4

**Explanation:**

The centripetal acceleration is by

a = v² / R

angular and linear velocities are related

v = w R

let's substitute

a = w² R

for initial condition

a₀ = w₀² R

suppose the initial angular velocity is wo, suppose the angular velocity doubles

a = (2w₀)² R

a = 4 (w₀² R)

a = 4 a₀

when reviewing the answers the correct one is a
