Power =Force * Velocity
Velocity = Distance/Time = 2/0.5 = 4 m/s
Therefore,
P = 1000*4 = 4000 W = 4 kW
There are warnings about using your cell phone while pumping gas because cell phone batteries can explode.
<h3>What is pumping gas?</h3>
When the vehicle is not having enough fuel to drive more miles, it needs to be fueled by petrol, diesel or natural gas. This is called pumping gas.
According to the rules of National Fire Protection Association, No one is allowed to use any type of electronic items while pumping gas. So, the cell phone is not allowed.
Phones develop static charge. It is believed that cell phone batteries can explode while pumping gas. It would be a real danger.
Thus, there are warnings about using your cell phone while pumping gas because cell phone batteries can explode.

Answer:
84 meters
Explanation:
Using these two kinematic equations : Vf= Vi +at and
D= [(Vi+Vf)/2]*t
Plugging in what we know into the first equation to solve for the Final velocity, you'll get Vf= 2 m/s + 4(m/s^2)*6s = 26m/s
plug time vi and vf into the second equation to solve for displacement.
Answer:
pressure of the water = 3.3 × 
pa
Explanation:
given data
velocity v1 = 1.5 m/s
pressure P = 400,000 Pa
inside radius r1 = 1.00 cm
pipe radius r2 = 0.5 cm
h1 = 0 (datum at inlet)
h2 = 5.0 m (datum at inlet)
density of water ρ = 1000 kg/m³
to find out
pressure of the water
solution
we consider here flow speed in bathroom that is = v2 and Pressure in bathroom is = P2
here we will use both continuity and Bernoulli equations
because here we have more than one unknown so that
v1 × A1 = v2 × A2 × P1 + ρ g h1 + (0.5)ρ v1² = P2 + ρ g h2 + (0.5) ρ v2²
now we use here first continuity equation for get v2
v2 = 
v2 = 
v2 = 6 m/s
and now we use here bernoulli eqution for find here p2 that is
P2 = P1 - 0.5× ρ ×(v2² - v1²) - ρ g (h2- h1 )
P2 = 400000 - 0.5× 1000 ×(6² - 1.5²) - 1000 × 9.81 × (5-0 )
P2 = 3.3 × pa
Nebular cloud should be the answer, but i believe nuclear fusion is the closest answer, because it fuses together to become a cloud
hope this helps
