A ball is thrown straight up with an initial speed of 30 m/s. How long will it take to reach the top of its trajectory, and high

will the ball go?
Physics

Answer:

About 3.06 seconds

Explanation:

v_f=v_o+at

Since at the peak of its trajectory, the ball will have no velocity, you can write the following equation:

0=30+(-9.81)t\\\\-30=-9.81t\\\\t\approx 3.06s

Hope this helps!

Calculate the frequency of visible light having a wavelength of 410 nm
maria [59]
Given: Wavelength λ = 410 nm  convert to Meters m = 4.10 x 10⁻⁷ m

Speed of light c = 3 x 10⁸ m/s

Required: Frequency  f = ?

Formula: c = λf 

               f = c/λ

               f = 3 x 10⁸ m/s/4.10 x 10⁻⁷ m

               f = 7.32 x 10¹⁴/s  or 732 Thz (Terahertz)

If R is the total resistance for a parallel circuit with two resistors of resistance r1 and r2, then . Find the resistance, r1,
Goshia [24]
For a parallel circuit with two resistors, the total resistance is calculated from the expression:

1/R = 1/R1 + 1/R2

We are given the total resistance, R, which is 20 ohms and R2 which is 75 ohms. We calculate R1 as follows:

1/20 = 1/R1 + 1/75
1/R1 = 11/300
R1 = 27.27 ohms
