Answer:
Magnetic field strength required for this is 0.25 T
Explanation:
As we know that the proton moves in circular path in uniform magnetic field
so the radius of the path of the circle is given as
here we know that
now we have
so we have
No. There's no relationship among the stars in a constellation, and they're not bound together by anything. They may be many light years apart, and just happen to lie in roughly the same direction from the Earth so they appear close together as seen by US.
A constellation could be formed from the tree right in front of you, the cat in the grass next to the tree, and the house and two cars five miles away in the same direction as the tree.
They appear to form a pattern or a picture only because the human brain is hard-wired to look for familiar patterns in random stuff. The constellations exist only in our minds.
<span>To answer this question with specific values, you would need a phase diagram for the substance in question. In more general terms, the pressure needs to be lower than the pressure of the triple point, the substance must be present in its solid state, and the temperature must rise high enough to produce a gas.</span>
First we determine the motor's efficiency - a ratio of the mechanical output power and the electrical input power:
The output mechanical power is directly proportional to torque and angular speed. From this relationship we can isolate the torque:
whereby the last expression uses the angular speed in rpm units.
(a) we calculate the torque, given that the motor draws 1.2 times the rated current, i.e., 48 Amps:
(b) use formula for the acceleration time:
The startup time will be 0.74s
Answer:
a = (v² − v₀²) / (2 (x − x₀))
Explanation:
v² = v₀² + 2a(x − x₀)
Subtract v₀² from both sides.
v² − v₀² = 2a(x − x₀)
Divide both sides by 2 (x − x₀).
(v² − v₀²) / (2 (x − x₀)) = a
