Pluto is the last so called planet so i am rambling on bc this website make me its Pluto
Answer:
Frequency
Explanation:
The intensity of light is increased by increasing the number of photon per second, and the number of photon per second is referred to as frequency. A photon the smallest unit of light. If the frequency is increased, the number of photons per second increases hence an increase in intensity.
Answer:
3.1 s
Explanation:
from the question we are given the the following:
Weight of books (Fb) = 305 N
Push force (Fp) = 516 N
distance (s) = 5.82 m
Angle of force exerted = 32 degrees
acceleration due to gravity (g) = 9.81 m/s^{2}
coefficient of friction Uk= 0.59
time (t) = ?
mass of the book (m) = weight / (g) = 305 / 9.8 = 31 kg
lets first get the net force from the summation of vertical forces
Fnet = Fpush + Fgravity
F net = 516 + 305sin32
F net = 677.6 N
now lets get the acceleration from the summation of the horizontal forces
Fpcos32 - friction force = m x a
Fpcos32 - (Uk x F net) = m x a
516cos32 - (0.59 x 677.6) = 31 x a
37.8 = 31a
a = 1.22m/s^{2}
now that we have our acceleration we can get the time from the equation of motion
s = ut + o.5at^{2}
u ( initial velocity ) = 0 because the box was initially at rest
5.82 = (0 x t ) + (0.5 x 1.22 x t^{2})
5.82 = 0.61t^{2}
t = 3.1 s

- (These are the most longest elements that have been around very long )
Answer:
the swing on the right is more likely to break
since the vertical component of the tension of the rope has to balance the weight. ie. the resultant tension in the rope is greater
