Answer:
<em>The net force that acts on the sailboat has a magnitude of 217 N and is applied at an angle of 64° north of east.</em>
Explanation:
<u>Mechanical Force</u>
The second Newton's law states the net force exerted by an external agent on an object of mass m is:
Where is the acceleration of the object. Note both the force and the acceleration are vectors. The relationship between them is the mass, a scalar.
This means the net force and the acceleration have the same direction.
The sailboat has a mass m= 350 Kg and moves at a=0.62 m/s^2. The magnitude of the net force acting on the boat is:
As stated above its direction is the same as the acceleration, thus:
The net force that acts on the sailboat has a magnitude of 217 N and is applied at an angle of 64° north of east.
Answer:
= 1.46 × 10 ¹⁰ electron
Explanation:
Given that
E, Electric field = 1000N/C
D, Diameter = 29cm
r, radius = 0.145
E = kq/r²
→ q = Er²/k
q = (1000 × (0.145)² ) / (9 × 10⁹)
q = 2.34 × 10⁻⁹C
q = Ne
where e = 1.6 × 10⁻¹⁹
N = (2.34 × 10⁻⁹) / (1.6 × 10⁻¹⁹)
= 1.46 × 10¹⁰ electron
