Blue light has a shorter wavelength than does red light, and since it travels at the same speed (in vacuum) as red light, has a higher frequency. This gives it a higher energy per photon.
A this refers to the make up of the soil
Answer:
2400 calories
Explanation:
given,
diameter of pizza,d₁ = 6 inches
calories of the 6 inches pizza = 600 calories
diameter of large size of pizza, d₂ = 12 inches
calories of the 12 inches pizza = ?
Area of the 6 inches pizza
A₁ = π x 3² = 9 π
Area of the 12 inches pizza
A₂ = π x 6² = 36 π
Ratio of 12 inch pizza to 6 inches
=
=
calories of the pizza
x = 2400 calories
Pizza of 12 inches is of calories is equal to 2400 calories
Answer:
The minumum speed the pail must have at its highest point if no water is to spill from it
= 2.64 m/s
Explanation:
Working with the forces acting on the water in the pail at any point.
The weight of water is always directed downwards.
The normal force exerted on the water by the pail is always directed towards the centre of the circle of the circular motion.
And the centripetal force, which keeps the system in its circular motion, is the net force as a result of those two previously mentioned force.
At the highest point of the motion, the top of the vertical circle, the weight and the normal force on the water are both directed downwards.
Net force = W + (normal force)
But the speed of this motion can be lowered enough to a point where the normal force becomes zero at the moment the pail reaches the highest point of its motion. Any speed lower than this value would result in the water spilling out of the pail. The water would not be able to resist the force of gravity.
At this point of minimum velocity,
Normal force = 0
Net force = W
Net force = centripetal force = (mv²/r)
W = mg
(mv²/r) = mg
r = 0.710 m
g = 9.8 m/s²
v² = gr = 9.8 × 0.71 = 6.958
v = √(6.958) = 2.64 m/s
Hope this Helps!!!
