The model represents Photosynthesis. Light, carbon dioxide, and water are the reactants. The products will be Sugar and Oxygen. Photosynthesis releases oxygen and glucose. Which is the energy that living things need to survive.
They travel linearly.
They have a negative electric charge.
They have particle property.
Magnets can deflect them.
Charge/mass ratio of the rays is constant.
They travel from the cathode to the anode.
Their properties are independent from the electrodes and gas present in the cathode ray tube.
Answer:
D. 6.25 J
Explanation:
∴ k = 50 N/m
∴ Δx = 0.5 m
⇒ EPE = 1/2*50 N/m*(0.5m)²
⇒ EPE = 6.25 N.m = 6.25 J
Answer:
28.16 g/mol
Explanation:
From Graham's law;
Let the rate of diffusion of gas X be 1.25
Let the rate of diffusion of CO2 be 1
Molecular mass of gas X= M
Molecular mass of CO2 = 44g/mol
1.25/1=√44/M
(1.25/1)^2 = 44/M
1.5625 = 44/M
M= 44/1.5625
M= 28.16 g/mol
At <span>standard temperature
and pressure, these elements have
very similar properties; they are all shiny, silvery-white, semi-reactive metals that have industrial and biological applications. The
Alkaline Earth Metals are elements of group 2 of the periodic table, which
includes beryllium, magnesium, calcium, strontium, barium, and radium.
Moreover, group 2 elements are nonmetallic
substances that are insoluble in water and heat resistant in nature.</span>
