solmaris [256]

Answer:

= 1000 hours

Explanation:

Earth's circumference is 10⁴ mile

speed of a sailboat is 10¹ mile/hour

distance = speed × time

10⁴ = 10¹  × t

t = 10⁴ / 10¹

t = 10³

= 1000 hours

A wire carries a current of 6.52 A in a direction that makes an angle of 44.8 degrees with the direction of a magnetic field of
Komok [63]

Answer:

F=4.27N

Explanation:

From the question we are told that:

Current  I = 6.52 A

Angle \theta= 44.8 \textdegree

Magnetic field   B= 0.258 T.

Length l=3.61m

Generally the equation for  Magnetic force F is mathematically given by

 F=BIlsin\theta

Therefore

 F=0.258*6.52*3.61*sin 44.8

 F=4.27N

An inclined plane has a ramp length of 4.0 meters and a height of 2.0 meters. What is the IMA of the inclined plane? 0.5 2.0 6.0
Aleonysh [2.5K]

Length of the ramp (L) = 4.0 m = Distance traveled by the effort

Height of the inclined plane (h) = 2.0 m = Distance traveled by the resistance

IMA = Ideal mechanical advantage

IMA = \frac{L}{h}

IMA = \frac{4.0}{2.0}

IMA = 2.0

Hence, the IMA of the inclined plane is 2.0
