Probably because darker colors absorb heat making darker colored clothing warmer than lighter colored clothing

A particle with a mass of 2.3 × 10-20 kg is oscillating with simple harmonic motion with a period of 3.0 × 10-5 s and a maximum

baherus [9]

Answer:

angular frequency is 209439.51 rad/sec

maximum displacement is 0.010504 m

Explanation:

Given data

mass = 2.3 × 10^-20 kg

period = 3.0 × 10^-5 s

maximum speed = 2.2 × 10^3 m/s

to find out

the angular frequency and maximum displacement

solution

we know angular frequency formula that is

angular frequency = 2 π / period

put here period value we get angular frequency

angular frequency = 2 π / 3.0 × 10^-5

angular frequency is 209439.51 rad/sec

maximum displacement formula is

speed = angular frequency × maximum displacement

put all value and we get maximum displacement

maximum displacement = 2.2 × 10^3 / 209439.51

maximum displacement is 0.010504 m

Calculate the electric field intensity at a point 3 cm away from point charge of 3 x 10^-9 C.

lukranit [14]

Answer:

The electric field intensity is 30000 N/C.

Explanation:

Given:

Magnitude of the point charge is, $q=3\times 10^{-9}\ C$

Distance of the given point from the point charge is, $d=3\ cm=0.03\ m$

Electric field intensity is directly proportional to the magnitude of point charge and inversely proportional to the square of the distance of the point and the given charge.

Therefore, electric field intensity 'E' at a distance of 'd' from a point charge 'q' is given as:

$E=\frac{kq}{d^2}$

Plug in $k=9\times 10^9\ N\cdot m^2/C^2, q=3\times 10^{-9}\ C, d=0.03\ m$ . Solve for 'E'.

$E=\frac{(9\times 10^9\ N\cdot m^2/C^2)(3\times 10^{-9}\ C)}{(0.03\ m)^2}\\\\E=\frac{27}{0.0009}\ N/C\\\\E=30000\ N/C$

Therefore, the electric field intensity at a point 3 cm from the point charge is 30000 N/C.
