Y = 42t - 16t^2
velocity = vt = dy/dt
= 42 - 32t
v(1) = 42 - 32
= 10 ft/s
Hope this helps
Answer:
41 turns
Explanation:
= Induced emf = 12.4 mV
= Current changing rate = 0.0275 A/s
L= Inductance
= Average flux = 0.00285 wb
N = Number of turns
Change in flux is given by
Flux through each turn is given by
The number of turns is 41

<span>1.0x10^3 newtons of force
1.0x10^2 kilograms of weight (assuming local gravity of 9.8 m/s^2)
I will assume that the external pressure is 1 atmosphere (101325 Pascals) since it wasn't specified in the problem. So let's simply multiply the area of the suction cup by the pressure and see what we get:
101325 P * 0.01 m^2
= 101325 kg/(m*s^2) * 0.01 m^2
= 1013.25 kg*m/s^2
= 1013.25 N
So the suction cup can support 1013.25 Newtons of force. Assuming the local gravitational acceleration is 9.8 m/s^2, let's see how many kilograms that is
1013.25 N / 9.8 m/s^2
= 1013.25 kg*m/s^2 / 9.8 m/s^2
= 103.3928571 kg
Rounding to 2 significant figures gives 1.0x10^3 newtons, or 1.0x10^2 kilograms.</span>
The relationship between resistance and current in a circuit is that if either resistance or current increase, then voltage increases; or vice versa for that matter. Another part in their relationship, is that resistance multiplied by current equals voltage so in order to calculate voltage, you must have resistance and current. I hope this helps!
