A motorcycle is following a car that is traveling at constant speed on a straight highway. Initially, the car and the motorcycle
Sunny_sXe [5.5K]

Answer:

a) 5.09 seconds

b) 107.07 meters

Explanation:

a) As we know

t_2- t_1 = \sqrt{\frac{2 X}{a} }

Substituting the given values we get

t_2 - t_1 = \sqrt{\frac{2 * 52}{4} } \\t_2 - t_1 = 5.09

It takes 5 .09 s for the motorcycle to accelerate until it catches up with the car

b)

X_{t`2} = v_i \sqrt{\frac{2X}{a} } + 0.5 a\sqrt{\frac{2X}{a} }\\X_{t`2} =  (v_i + 0.5 a) \sqrt{\frac{2X}{a} }\\X_{t`2} =  ( 19 + 2)  \sqrt{\frac{2* 52}{4} }\\X_{t`2} =  21 * 5.09\\X_{t`2} = 107.07

A manometer is used to measure the air pressure in a tank. The fluid used has a specific gravity of 1.25, and the differential h
Sloan [31]

Answer:

77.88 lbm/ft³

Explanation:

Given,

Specific gravity, SG = 1.25

Density of water, ρ = 62.30 lbm/ft³

density of the fluid =

   = S.G x ρ_{water}

   = 62.30 x 1.25

   = 77.88 lbm/ft³

Density of the fluid is equal to 77.88 lbm/ft³

A closed flat loop conductor with radius 2mm is located in a changing uniform magnetic field. If the emf induced in the loop is
BARSIC [14]

Answer:

Rate of magnetic field is 15923.668 T/sec

Explanation:

We have given radius of loop conductor r = 2 mm = 0.002 m

Induced emf = 2 volt

As the magnetic field and plane are perpendicular to each other so angle between magnetic field and area is 0°

Cross sectional area of the conductor is equal to A=\pi r^2

A=3.14\times 0.002^2=1.256\times 10^{-6}m^2

Induced emf is given by e=\frac{-d\Phi }{dt}=-A\frac{dB}{dt}

2=1.256\times 10^{-6}\times \frac{dB}{dt}

\frac{dB}{dt}=159235.668T/sec
