Answer:
the speed is equal to 6 m/s
Explanation:
Part (a): Magnetic dipole moment
Magnetic dipole moment = IA, I = Current, A = Area of the loop
Then,
Magnetic dipole moment = 2.6*π*0.15^2 = 0.184 Am^2
Part (b): Torque acting on the loop
T = IAB SinФ, where B = Magnetic field, Ф = Angle
Then,
T = Magnetic dipole moment*B*SinФ = 0.184*12*Sin 41 = 1.447 Nm
I dont know if it right but <span>Use a universal power adapter. This is perhaps the most obvious solution to your battery woes. Readily found at most retail outlets that carry electronics, a universal power adapter can range anywhere in price from $30 to $100 or more. The adapter comes with multiple tips, one of which will likely fit your laptop’s charging port. When plugged in, the adapter will not only power your laptop, but will charge its battery as well.</span>
We know that:
d=vt
d=32mph*5h
d=160mi
Answer:
350J
Explanation:
Given parameters:
Weight of bag = 20N
Distance moved horizontally = 35m
Force applied = 10N
Unknown:
Work done on the bag = ?
Solution:
Work done is the force applied to move a body through given distance.
Work done = Force applied x distance
So;
Work done = 10 x 35 = 350J
