Answer:
True
Explanation:
The reason is because factories or other places like a lab have to test if its safe and a good product to sell
<span>Answer:
t = I B A sin teta
2.5 x 10^-2 = 10 B (pi 0.1^2 / 4) cos 23
B = 0.06 tesla</span>
The frequency of the applied voltage is constant
Acceleration
On a velocity time graph, the y-axis is velocity, and the x-axis is time. So the slope is the change in velocity for every unit of change in time.
acceleration- the rate of change of velocity per unit of time.
hope this helps :)
Answer:
Explanation:
q₁ = 8 x 10⁻⁶ C , q₂ = 3.5 x 10⁻⁶ C , q₃ = -2.5 x 10⁻⁶ C
Force between charge = 9 x 10⁹ x q₁ q₂ / d²
Force on q₁ due to q₂
= 9 x 10⁹ x 8 x 10⁻⁶ x 3.5 x 10⁻⁶ /( .10 )²
= 25.2 N . This force will be negative as it will point towards left ( q₂ will repel q₁ )
Force on q₁ due to q₃
= 9 x 10⁹ x 8 x 10⁻⁶ x 2.5 x 10⁻⁶ /( .15 )²
= 8 N . This force will be negative as it will point towards left ( q₃ will attract q₁ )
Net force = 25.2 N - 8 N
= 17.2 N .
