Answer:
<em>The distance covered by comet is </em>
Explanation:
Speed is defined as the rate of change of distance with time. It is given by the equation speed= 
Thus distance= 
In this problem it is given that speed of comet= 
time travelled by the comet= 4 hours
Thus distance=
= 
= 
Momentum = m • v
Original momentum = m • 10 m/s north
Final momentum = m • 15 m/s north
Change = m • (15 - 10) m/s north
Change = m • +5 m/s north
Change = +60 kg-m/s north
The Incan used there many techniques to more efficiently use water.
Answer:
the magnitude and the direction of the total magnetic field is 0.4 Am² antiparallel to the area vector
Explanation:
Given that:
The area vector of a square loop has 5 numbers of turns i.e n = 5
each with side length = 0.2 m
Current I = 2 A
uniform magnetic field = 50.0 T
Now; the magnitude of the total magnetic field B is calculated as :
B = IA
where;
I = current
A = area ( n × l²)
B = I ( n × l²)
B = 2 × 5 × 0.2²
B = 0.4 Am²
The direction of the magnetic moment is antiparallel to the area vector;
Hence ; the magnitude and the direction of the total magnetic field is 0.4 Am² antiparallel to the area vector
