It is the process in which green plants make their food through a green pigment known as Chlorophyll by using sunlight, Carbon-dioxide and water. The result comes out with the formation of Oxygen as a byproduct. But in night they also respire like animals and photosynthesis does not occur. Photo means light and synthesis means manufacture.

Photo means light. Synthesis refers to manufacture. Photosynthesis is the process by which green plants manufacture their own food which is mainly carbohydrates or starch in the presence of sunlight under the influence of a pigment called chlorophyll which acts as a biological catalyst and by using carbon dioxide and water as the raw material. This process results in the evolution of oxygen gas.

equation of photosynthesis :

6CO2 +6H2O ==>C6H12O6+6O2

a student stands several meters in front of a smooth reflecting wall, holding a board on which a wire is fixed at each end. the

Andrew [12]

Answer:

Explanation:

From the question we are told that

The length of the wire is $L = 75.0cm = \frac{75}{100} = 0.75 \ m$

The mass of the wire is $m = 2.25 \ g = \frac{2.25}{1000} = 0.00225 \ kg$

The tension is $T = 400 \ N$

The frequency of the beat heard by the second student is

$f_b = 8.30\ beat/second$

The speed of the wave generated by the vibration of the wire is mathematically represented as

$v = \sqrt{\frac{TL}{m}}$

substituting values

$v = \sqrt{\frac{400 *0.75}{0.00225}}$

$v = 365.15 m/s$

The wire is vibrating in its third harmonics so the wavelength is

$\lambda = \frac{2L}{3}$

substituting values

$\lambda = \frac{2*0.75}{3}$

$\lambda = 0.5 \ m$

The frequency of this vibration is mathematically represented as

$f = \frac{v}{\lambda }$

substituting values

$f = \frac{365.15}{0.5 }$

$f = 730.3 Hz$

The speed of the second student (Observer) is mathematically represented as

$v_o = [\frac{f_b}{2f} ] * v$

substituting values

$v_o = [\frac{8.30}{2* 730.3} ] * 365.15$

$v_o = 2.08 \ m/s$

(a) find the magnitude of the gravitational force between a planet with mass 7.50 3 1024 kg and its moon, with mass 2.70 3 1022

anzhelika [568]

The magnitude of the gravitational force between two bodies is the product of their masses divided by the square of the distance between them. So we have F = M1*M2 / r^2. M1 = 7.503 * 10e24 and M2 = 2.703 * 10e22 and r= 2.803 * 10e8; r^2 = 5.606 *10e16. So we have 7.503 *2.703 *10^(24+22) = 20.280 * 10^(46). Then we divide our answer by 5.606 * 10e16 which is the distance ; then we have 3.6175 * 10 e (46- 16) = 3.6175 * 10e30. To find the acceleration we use Newton's second law F = ma. F is 3.6175 * 10e30 and M is 7.503 * 10e24 so a = F/M and then we have 3.6175/7.503 * 10e (30-24) = 0.48 * 10e6. Similarly for moon, we have a = 3.6715/2.703 * 10e(30-22). = 1.358 * 10e8
