The magnet is at a gravitational force while the paper clip is at an applied force
Answer:
100 Joules
Explanation:
Applying,
W = mgh................... Equation 1
Where W = workdone to hold the box above the ground, mg = weight of the box, h = height of the box.
From the question,
Given: mg = 10 newtons, h = 10 meters.
Substitute these values into equation 1
W = 10×10
W = 100 Joules.
Hence the amount of workdone is 100 Joules
The conductor is the metal wire inside or encased in the insulator, which as stated covers or insulates the conductor.
Answer:
x = 42 m
y = -28 m
vx = 17.5 m/s
vy = -23.5 m/s
Explanation:
if the throw point is the origin and UP and AWAY are the positive directions.
s = s₀ + v₀t + ½at²
v = u + at
horizontal position = 0 + 17.5 m/s(2.4 s) + ½(0)(2.4)² = 42 m
vertical position = 0 + 0(2.4) + ½(-9.8 m/s²)(2.4 s)² = -28 m
horizontal velocity = 17.5 + 0(2.4) = 17.5 m/s
vertical velocity = 0 + (-9.8)(2.4) = -23.5 m/s
