The force needed to accelerate a vehicle with a mass of 1000kg at a rate of 5m/s2 would be 5000
Work = (force) x (distance)
1,008 J = (force) x (28 m)
Divide each side by 28m : (1,008 kg-m²/sec²) / (28 m) = force
Force = 36 kg-m/s² = 36 Newtons .
(about 8.1 pounds)
It doesn't matter what that force accomplishes.
It could be moving a brick, lifting a fish, or pushing a little red wagon.
In order to do 1,008 joules of work in 28 meters, it takes 36 N of force,
in the direction of the 28 meters.
65% x 70 = 45.5
The mass of oxygen in his body is 45.5 kg
Answer:
19.5 mJ
Explanation:
Assuming perfect components without resistance or losses, the circuit should oscillate indefinetly.
The circuit will have a natural pulsation of



So, by the time t = 2.4 ms, 333.33 cycles would have passed

Therefore it would be at one third after the beginning of the cycle. The circuit would be in an equivalent state as t = (7.2 us)/3 = 2.4us
At t=0 the capacitor is fully charged, so the voltage is maximum and the current is 0. The current will increase towards a maximum of 800 mA at t=T/4, then decreas to 0 at t=T/2, decrease to -800 mA at 3T/4 and go back to 0 at t=T following a sine wave.
The equation of this sine wave would be


Since w = 2π/T
w * T = 2π

The current stored in an inductor is


Answer:
Matter is made up of particles that are constantly moving. All particles have energy, but the energy varies depending on the temperature the sample of matter is in. This in turn determines whether the substance exists in the solid, liquid, or gaseous state.
