Answer:
Acceleration
Explanation:
Acceleration is the change in velocity/speed per unit time
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
Answer:
do what for you there is no question???
Answer:
70.6N
Explanation:
We are given that
Mass of crate=12 kg
Coefficient of static friction=[tex\mu=[/tex]0.40
Horizontal component force is equal to friction force
Force along vertical direction
..(2)
Using equation(2) in equation (1)
Substitute the values then we get
Hence, the minimum force needed to start the crate moving=70.6N
