Formula for kinetic energy of an object:
KE = 0.5mv²
m is the mass and v is the velocity.
Formula for the work done on a charged object by moving it through a potential difference:
W = ΔVq
ΔV is the potential difference and q is the charge of the object.
To find the potential difference needed to decelerate an electron to rest, set the work done on the electron equal to its kinetic energy:
W = KE
Substitute W = ΔVq and KE = 0.5mv²
ΔVq = 0.5mv²
Given values:
q = 1.6×10⁻¹⁹C
m = 9.11×10⁻³¹kg
v = 6.0m/s
Plug in the given values and solve for ΔV
ΔV×1.6×10⁻¹⁹ = 0.5×9.11×10⁻³¹×6.0²
ΔV = 1.02×10⁻¹⁰V
No because since the hills are the same size the roads that are on the mountains will go the same way as the mountains
THE UNBALANCED FORCE THAT CAUSES OBJECTS TO MOVE IN A CIRCULAR PATH IS CALLED A CENTRIPETAL FORCE. GRAVITY PROVIDES THE CENTRIPETAL FORCE THAT KEEPS OBJECTS IN ORBIT. THE WORD CENTRIPETAL MEANS "TOWARD THE CENTER
Answer:
Explanation:
Biomass is the total quantity or weight of organisms in a given area or volume.
car starts from rest
final speed attained by the car is
acceleration of the car will be
now the time to reach this final speed will be
so it required 1.39 s to reach this final speed
