Answer:
Correct answer: F = 214.56 N
Explanation:
Given:
V₀ = 0 m/s initial speed
V = 44.7 m/s speed after t = 29 seconds
m = 96 kg
F = ? horizontal force
Taking off an airplane is a uniformly accelerated motion to which the formula applies:
V = V₀ + a t and V₀ = 0 m/s
V = a t ⇒ a = V / t = 44.7 / 20 = 2.235 m/s²
a = 2.235 m/s²
the horizontal force is calculated using the formula:
F = m · a = 96 · 2.235 = 214.56 N
F = 214.56 N
God is with you!!!
Answer:
Explanation:
Electrical energy = potential x charge
potential = 12V ,
Charge = 95 amp-hours
= 95 x 60 x 60 coulomb
= 342000 coulomb
Electrical energy stored in battery = 342000 x 12
= 4104000 J
= 4.1 x 10⁶ J .
Heyyyy I wish I could help but I don’t know
Hello!
On a cold winters day, if you left a drink setting outside, it could freeze because the heat (related to the kinetic energy) of the atoms in the drink will be transferred to the environment to achieve energy equilibrium.
Heat transfer occurs by various mechanisms, flowing from the hottest body to the coldest, that's why the heat goes from the drink, which has a higher temperature (and kinetic energy) to the environment, which has a lower temperature. This is described by the second law of thermodynamics
C Bc it’s the right answers not wrong
