<span>You can start with the equations you know
a=v^2/r = (2pi*r/T)^2/r = 4pi^2r/T^2
Radius of earth (R) = 6378.1 km
Time in one day (T) = 86400 seconds
Latitude = 44.4 degrees
If you draw a circle and have the radius going out at a 44.4 degree angle above the center you can then find the r.
r=Rcos(44.4)
r=6378.1cos(44.4)
r= 4556.978198 km or 4556978 m
Now you can plug this value into the acceleration equation from above...
a= 1.8*10^8/7.47*10^9
a= .0241 m/s^2 </span>
Answer:
E=
Explanation:
q: particle's charge
k: coulomb constant
E=E*u
r=r*u
r=distancia vectorial entre P y S
r=distancia escalar entre P y S
E: Electric field vector
E: magnitud of magnetic field vector
u: unit vector radial
then:
r=r*u
r=P-S=(-1,-2,-4)m
E=
u=r/r=
Hey luv, what’s the two statements?
Answer:
I think it's d. The coil gains an electical current
Explanation:
Answer:
W & X
Explanation:
gradient of a velocity - time graph indicates the acceleration.
straight lines ,
- positive gradient ----> acceleration
- negative gradient-----> deceleration
- gradient = 0 ------> constant velocity
curved lines indicate changing acceleration/deceleration
If we consider the gradient values here ,
W ----- 15/1 = 15
X-------(20-15)/1 = 5
Y ------(0/2) = 0
Z-------(0-20)/1 = (-20)
looking at these we can say
Y motion has no acceleration : moves in a constant velocity
Z motion has a negative acceleration (deceleration)
W & X have accelerating motion.
