Answer:600 V

Explanation:

 Given

Q=-8 mC

W=4.8 J

And we know

W=QV

V_b-V_a=V_{ba}

4.8=\left ( 8\times 10^{-3} \right )V_{ba}

V_{ba}=0.6\times 10^{-3}

V_{ba}=600 V

A train of mass 50000 kg starts from rest and moves with uniform acceleration 5 km/h2 then, find its kinetic energy after 30 min
r-ruslan [8.4K]

Answer:

12 kJ

Explanation:

Given:

v₀ = 0 km/h

a = 5 km/h²

t = 30 min = 0.5 h

Find: v

v = at + v₀

v = (5 km/h²) (0.5 h) + 0 km/h

v = 2.5 km/h

v = 2.5 km/h × (1000 m/km) × (1 h / 3600 s)

v = 0.694 m/s

KE = ½ mv²

KE = ½ (50,000 kg) (0.694 m/s)²

KE = 12,000 J

KE = 12 kJ

Suppose you walk 17 m straight west and then 26.5 m straight north. What is the compass direction, in degrees measured West of N
garik1379 [7]

Answer:32.7

Explanation:

You must first make a right triangle with the two legs being 17 m west and 26.5 m north. To find the degree measurement west of north you must find the angle between the north leg and the hypotenuse. then just use inverse tangent of (17/26.5) which is 32 .7 degrees
