Answer:
Impulse. Impulse is when a force is applied to an object for an amount of time.
Explanation:
It can't be momentum because momentum is the motion of a moving body, that is measured as a product of its mass and velocity.
It' cant be inertia because inertia is when an object doesn't move/ it does nothing as well as an object remaining unchanged.
And it can't be acceleration because acceleration is when how fast an object can go/ there velocity.
And that leaves us with impulse, so that's the correct one.

Evaporation is the process of the hydrological cycle maintained by the ocean's large surface area.
Answer:
Basketball
Explanation:
Basketball was invented to keep athletes warm in the winter.
Answer:
The weather will clear up and get sunnier.
Explanation:As weather forecasters monitor air pressure, falling barometer measurements can signal that bad weather is on the way. In general, if a low pressure system is on its way, be prepared for warmer weather with storms and rain. If a high pressure system is coming, you can expect clear skies and cooler temperatures.

Answer:
-27 mJ
Explanation:
The work done in moving the three charges an infinite distance from each other is the electric potential energy of the system. Let q₁ = q₂ = 6 μC = 6 × 10⁻⁶ C, q₃ = -3.5 μC = -3.5 × 10⁻⁶ C. Let r₁ be the distance between q₁ and q₃. r₁ = 2 m. Let r₂ be the distance between q₂ and q₃. r₂ = 2 m. Let r₃ be the distance between q₁ and q₂. r₃ = √(2 - 0)² + (0 - 2)² = √4 = 2 m
The potential energy is thus U
U = kq₁q₂/r₃ + kq₁q₃/r₁ + kq₂q₃/r₂
Since q₁ = q₂ = q and r₁ = r₂ = r₃ = r
U = kq(q + 2q₃)/r =
U = 9 × 10⁹ Nm²/C² × 6 × 10⁻⁶ C(6 × 10⁻⁶ C + 2 × -3.5 × 10⁻⁶ C)/2 m
U = 9 × 10⁹ Nm²/C² × 6 × 10⁻⁶ C(6 × 10⁻⁶ C - 7 × 10⁻⁶ C)/2 m
U = 9 × 10⁹ Nm²/C² × 6 × 10⁻⁶ C(- 1 × 10⁻⁶ C)/2 m
U = -54 × 10⁻³ Nm²/2 m
U = -27 × 10⁻³ Nm
U = -27 × 10⁻³ J
U = -27 mJ
So a work of -27 mJ must be done to move the charges an infinite distance away from each other
