Answer:
Explanation:
Distance between proton and electron = r = 5.5 x 10⁻¹³ m
Magnitude of charge on electron and proton = 1.67 x 10⁻¹⁹ C
To find their initial acceleration first force between them is:
Initial acceleration of electron and proton are found using
F=ma
a=F/m
Answer:
d = 98.67m
Explanation:
equation:
vf^2 = vi^2 + 2ad
(44m/s)^2 = (0m/s)^2 + 2(9.81m/s^2)(d)
1936m^2/s^2 = 19.62m/s^2(d)
divide both sides by 19.62m/s^2
d = 98.67m approximately
Answer:
light energy transfers electrons from water (H 2 O) to carbon dioxide (CO 2), to produce carbohydrates. In this transfer, the CO 2 is "reduced," or receives electrons, and the water becomes "oxidized," or loses electrons
Explanation:
Answer:
The banking angle required is .
Explanation:
Banking of a road is the act of constructing a road along a curved path at a certain angle to avoid skidding-off of vehicles plying it. Centripetal force is required to pull the object moving with a velocity 'v' towards the center of the curve for stability.
The velocity of a car navigating a banked road is given by:
v =(rg ÷ tanθ)
where: r is the radius of the road, g is the gravitational force and θ is the banking angle.
⇒ = rg ÷ tanθ
tanθ =
θ =
= (given that g = 10)
=
= 1.4663
θ =
The banking angle required is .
