How would you determine the volume of an irregular shaped object.

Archy [21]

You can use the displacement method or the eureka can so basically in the displacement can what you have to do is to put some water into a measuring cylinder and measure its volume before adding the irregular shaped object and then measuring the level of water which had been displaced and then eureka can you can check online

A line of charge starts at x = +x0 and extends to positive infinity. The linear charge density is λ = λ0x0/x. Determine the elec

kari74 [83]

Explanation:

it is given that, the linear charge density of a charge, $\lambda=\dfrac{\lambda_ox_o}{x}$

Firstly, we can define the electric field for a small element and then integrate for the whole. The very small electric field is given by :

$dE=\dfrac{k\ dq}{x^2}$ ..........(1)

The linear charge density is given by :

$\lambda=\dfrac{dq}{dx}$

$dq=\lambda.dx=\dfrac{\lambda_ox_o}{x}dx$

Integrating equation (1) from x = x₀ to x = infinity

$E=\int\limits^\infty_{x_o} {\dfrac{k\lambda_ox_o}{x^3}}.dx$

$E=-\dfrac{k\lambda_ox_o}{2}\dfrac{1}{x^2}|_{x_o}^\infty}$

$E=\dfrac{k\lambda_o}{2x_o}$

Hence, this is the required solution.

Two masses traveling at the same speed v₀ collide head on. Nothing is known about the collision other than that it is not comple

alex41 [277]

Answer:

false

Explanation:

Elastic collision: the collision is said to be elastic if the kinetic energy is conserved during the collision.

If the kinetic energy is not conserved, then the collision is not elastic.

So, here no information is given so we cant say about the type of collision.

So, it is False.

Which of the following illustrates 2 resistors in a series circuit?

umka2103 [35]

Explanation :

An electrical circuit can be either connected in series or parallel.

Series combination: The current flowing in each resistor is the same and the equivalent resistance is given by :

$R{eq}=R_1+R_2+R_3+.................+R_n$

Parallel combination: The voltage for all components in the parallel combination is the same. The equivalent resistance is given by :

$\dfrac{1}{R_{eq}}=\dfrac{1}{R_{1}}+\dfrac{1}{R_{2}}+\dfrac{1}{R_{3}}......................+\dfrac{1}{R_{n}}$

So, our of given options the correct one is (b) because the current flowing in both the resistors is the same.
