I think it might be A. I’m sorry if I’m wrong
If we have the angle and magnitude of a vector A we can find its Cartesian components using the following formula
Where | A | is the magnitude of the vector and 
is the angle that it forms with the x axis in the opposite direction to the hands of the clock.
In this problem we know the value of Ax and Ay and we need the angle .
Vector A is in the 4th quadrant
So:
So:
So:
= -47.28 ° +360° = 313 °
= 313 °
Option 4.
Answer:
Explanation:
change in flux = no of turns x area of coil x change in magnetic field
= 163 x π 2.65² x 10⁻⁴ x ( .481 - 0 )
= 1728.84 x10⁻⁴ weber
rate of change of flux = change in flux / time
= 1728.84 x10⁻⁴ / .149
= 11603 x10⁻⁴ V .
volt induced = 1.16 V
current in the circuit
= volt induced / resistance
1.16 / 10.7 = .1084 A
energy dissipated = i²Rt where i is current , R is resistance and t is time.
= .1084² x 10.7 x .149
= .018734 J
= 18.73 mJ .
Answer:
The answer to your question is: Chemical change
Explanation:
Chemical Change is a change where substances change their properties because new substances are obtain. This is the right answer.
Compressibility
is a property in which a substance is compressed but it continous being the being so this answer is wrong.
Malleability is a property in whcih substances are flattened into thin sheets but they don't change their properties. This answer is wrong.
Physical Change is a change in which a substance changes its physical state but the properties are the same than the original substance, this answer is wrong.
Answer: How are nuclear reactions used to meet the world's energy needs? Both fusion and fission are used to generate electricity, but more fission reactors than fusion reactors are in use. ...
