Answer:
16 / 4 = ratio of diameters
A = pi r^2
A16 / A4 = pi * 8^2 / (pi 2^2) = 16
The light gathering power would increase by a factor of 16
Answer:
radio waves, microwaves, infrared, visible, UV, X-rays, gamma rays
Explanation:
Electromagnetic waves consist of oscillating electric and magnetic fields which vibrate in a direction perpendicular to the direction of motion of the wave (transverse wave). Electromagnetic waves travel in a vacuum with a speed of (speed of light), and they are classified into 7 different types according to their wavelength.
From longer to shorter wavelength, these types are:
Radio waves (wavelength > 30 cm)
Microwaves (30 cm - )
Infrared ()
Visible light (750 nm - 380 nm)
UV radiation (380 nm - 8 nm)
X-rays (8 nm - 6 pm)
Gamam rays (< 6 pm)
There isn’t a best anime , but in my opinion any anime on Netflix is good other than DBZ too many episodes and storyline gets messed up.
Answer:
Frictional force, F = 45.9 N
Explanation:
It is given that,
Weight of the box, W = 150 N
Acceleration,
The coefficient of static friction between the box and the wagon's surface is 0.6 and the coefficient of kinetic friction is 0.4.
It is mentioned that the box does not move relative to the wagon. The force of friction is equal to the applied force. Let a is the acceleration. So,
Frictional force is given by :
F = 45.9 N
So, the friction force on this box is closest to 45.9 N. Hence, this is the required solution.
1). D. Combined Gas Law
3.) D. Pressure and temperature
4.) C. Boyles law
