Newton's first law of motion. An object in motion tends to stay in motion. Since there is no friction in space to slow it down it just keeps going

A motorcycle cover a distance of 1.8 km in 5 minute. calculate its average velocity?

OlgaM077 [116]

Answer:

$solution \\ distance \: travelled = 1.8 \: km \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 1.8 \times 1000m \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 1800 \: m \\ time \: taken = 5 \: minute \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 5 \times 60 \: seconds \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 300 \: seconds \\ average \: velocity = \frac{distance \: travelled}{time \: taken} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{1800}{ 300} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 6 \: {ms}^{ - 1}$

A uniform electric field is produced due to the charge distribution inside the closed cylindrical surface. (a) What type of char

DiKsa [7]

Answer with Explanation:

a. Option d is true.

a negatively charged plane parallel to the end faces of the cylinder

b. Radius of cylinder, r=0.66m

Magnitude of electric field, E=300 N/C

We have to find the net flux through the closed surface.

Net electric flux, $\phi=-2 EA=-2E(\pi r^2)$

$\phi=-2\times 300\times (3.14\times (0.66)^2)$

$\phi=-820.67 Nm^2/C$

Net charge, $Q=\epsilon_0\times \phi$

Where

$\epsilon_0=8.85\times 10^{-12}$

$Q=-820.67\times 8.85\times 10^{-12}$

$Q=-7.26\times 10^{-9} C$

$Q=-7.26nC$

Where $1nC=10^{-9}C$

The graph below shows the variation with distance r from the nucleus of the square of the wave function, Ψ^2, of a hydrogen atom

Ludmilka [50]

The region a represents the distance of the electron from the nucleus.

According to the wave mechanical model of the atom, the probability of finding an electron within a given volume element (representing the atom) is the square of the wave function psi.

Since a is the region in space where there is the greatest probability of finding the electron in the atom, it follows that distance of the electron form the atom is always a.

What is the effect of load resistor on ripple factor

Zolol [24]

ripple factor can be reduced by increasing the value of the load resistor (which means reducing the load of the circuit)
