Answer:
<h3><u>ELECTRIC POTENTIAL</u></h3>
• the amount of work needed to move a unit charge from a reference point to a specific point against an electric field.
Answer:
F = 4399 KN
Explanation:
given,
mass of automobile = 890 kg
initial speed = 48 km/h
= 48 × 0.278 = 13.34 m/s
using equation of motion
v² = u² + 2 a × s
0 = 13.34² - 2 a ×0.018
a = 4943.21 m/s²
F = m × a
F = 890 × 4943.21
F = 4399456.9 N
F = 4399 KN
hence, the Net force is F = 4399 KN
ANSWER IS NOT FALSE IT IS True
Answer: A. FW = 20N x sin60°
Explanation: This is because resolution of the forces is taking along the horizontal plane.
Answer: State and explain, in terms of the forces acting,how the acceleration of the object varies during its fall. As the object is released two forces act on it. Its weight and and air resistance. At this point its weight is much greater due to the force of gravity on the object so it accelerates downward.
