Answer:
Explanation:
The magnetic moment of a current loop is simply the current times the area of the loop. In this case...
height of triangle = 2.00*tan(55) = 2.856 m
Area=0.5*base*height
=0.5*2*2.856
=2.856 m²
a)
magnetic moment = area * current = 2.856 * 5.26 = 14.994 A.m²
b)
then the torque is simply the B field times the magnetic moment
torque = B * mag moment = 1.6 * 15.022 = 24.03 N-m
Answer:
-
Both exceed the matter-energy equivalent of luminous matter
- Dark matter has only an attractive gravitational effect, while the dark energy is repulsive in nature
Explanation:
Dark matter is defined as the matter which consists of about 85% of the total matter of the universe and is no-baryonic in nature.
It is attractive in nature and exerts gravitational pulling effect. Even individual galaxies are under the influence of dark matter. It is way more powerful than the visible matter.
Dark energy is that form of energy which is said to be responsible for the universe's expansion and is repulsive in nature
ANSWER:
22 Hz.
Explanation:
Frequency = (speed) divided by (wavelength) = (330) / (15) =
Answer:position relative to the starting point
Explanation:
Using the two kinematic equations that can be used for this problem are:
Vf = Vi + at and d=Vit +(1/2)*at^2
Since Vi (initial velocity) = 0
The equations can further be simplified where a is the acceleration, t is the time, Vf is the final velocity which is 70 miles per hour and d is 6 miles
Vf = at
70 = at
a = 70/t---equation 1
d=(1/2)*a*(t^2)
6 = (1/2)*a*(t^2) ---equation 2
Substituting equation 1 to equation 2.
6= (1/2)*(70/t)*(t^2)
6= 35t
t= 0.17142 hours or 10.28571 mins or 617.14 sec
