Answer:
Explanation:
Important here is to know that due north is a 90 degree angle, due east is a 0 degree angle, and due south is a 270 degree angle. Then we find the x and y components of each part of this journey using the sin and cos of the angles multiplied by each magnitude:
Add them all together to get the x component of the resultant vector, V:
Do the same to find the y components of the part of this journey:
Add them together to get the y component of the resultant vector, V:
One thing of import to note is that both of these components are positive, so the resultant angle lies in QI.
We find the final magnitude:
and, rounding to 2 sig dig's as needed:
1.0 × 10² m; now for the direction:
58°
Answer:
0.625 A
Explanation:
Vs = 7500 V, Is = 0.01 A
Vp = 120 V
Let the primary current be Ip.
As the transformer is ideal, so input power is equal to the output power
Vp x Ip = Vs x Is
120 x Ip = 7500 x 0.01
Ip = 0.625 A
Answer:
Electrical energy. Jump to navigation Jump to search. Electrical energy is energy derived from electric potential energy or kinetic energy. When used loosely, electrical energy refers to energy that has been converted from electric potential energy
Explanation:
Answer:
<u>Very low</u>
<u>Explanation:</u>
It is fair to say to a reasonable extent that there are very low chances that radio transmissions from Earth or messages sent on distant space probes will ever be received by living beings
.
Bear in mind that for years some scientists have believed without any substantial evidence that there are other living beings in distant space.
There are 60 seconds in a minute.
This means that 5 minutes would be 60 times 5.
60×5 = 300
There are 300 seconds in 5 minutes.
