This problem involves Newton's universal law of gravitation and the equation to follow would be.
F = GM₁M₂/r²
Given: M₁ = 0.890 Kg; M₂ = 0.890 Kg; F = 8.06 x 10⁻¹¹ N; G = 6.673 X 10⁻¹¹ N m²/Kg²
Solving for distance r = ?
r = √GM₁M₂/F
r = √(6.673 x 10⁻¹¹ N m₂/Kg²)(0.890 Kg)(0.890 Kg)/ 8.06 x 10⁻¹¹ N
r = 0.81 m
S=ut+a(t^2)/2 = a(t^2)/2 [since u=0] =(v/t)*(t^2)/2 [since a=(v-u)/t=v/t] =vt/2 =180*{25/(60*60)}/2 km = 0.625 km =625 m
Answer:
Put away guns in a lockbox that is secure and in a discrete location
Explanation: Took the test. Trust me ;)
It's true
work measure by joule.
Energy = work/time
= joule/s .
and joule/s represents watt
1. The equivalent resistance in a <em>series </em>circuit, like the one shown, is given by the general equation
where <em>N </em>is the number of resistors in series. Here, there are four resistors in series. Using our equation with <em>N = 4</em>, we obtain
2. The current in this series circuit is equal to the voltage divided by the equivalent resistance (a relationship you can derive from Ohm's law):
