The spectrum of the Sun, whose surface temperature is about 5,800 K, peaks at a wavelength of light and other electromagnetic radiation that on the whole follow ... Furthermore, the hotter star gives off more of its energy at shorter wavelengths.

Doss [256]

Answer:

$t - t_1 = \frac{-\omega_o + \sqrt{\omega_o^2 + 8\alpha(2\omega_o t + \alpha t^2)}}{4\alpha}$

Explanation:

After time "t" the angular position of A is given as

$\theta_a = \theta_o + \omega_o t + \frac{1}{2}\alpha t^2$

now we know that B start motion after time t1

so its angular position is also same as that of position of A after same time "t"

so we have

$\theta_b = \theta_o + \frac{\omega_o}{2} (t - t_1) + \frac{1}{2}(2\alpha) (t - t_1)^2$

now since both positions are same

$\theta_a = \theta_b$

$\omega_o t + \frac{1}{2}\alpha t^2 = \frac{\omega_o}{2}(t - t_1} + \alpha(t - t_1)^2$

$2\omega_o t + \alpha t^2 = \omega_o(t - t_1) + 2\alpha(t - t_1)^2$

$t - t_1 = \frac{-\omega_o + \sqrt{\omega_o^2 + 8\alpha(2\omega_o t + \alpha t^2)}}{4\alpha}$

A girl of weight 500 N climbs on top of a 2.0 m high wall. By how much does her g.p.a increase?

Anna007 [38]

Answer:

By 1000 joules

Explanation:

Given

$Weight = 500N$

$Height = 2.0m$

Required

By how much does her GPA increases

To do this, we simply calculate the potential energy.

$GPE = mgh$

Where

$mg = Weight = 500N$

At the ground level, the height is 0

i.e. $h = 0$

So:

$GPE = 500N * 0 = 0$

At:

$h = Height = 2.0m$

So, we have:

$GPE = mgh$

$GPE = 500N * 2.0m$

$GPE = 1000J$

Calculate the difference

$\triangle GPE = 1000J - 0J$

$\triangle GPE = 1000J$

Hence, it increases by 1000 joules
