STatiana [176]

Answer:

a = 0.55 m / s²

Explanation:

The centripetal acceleration is given by the relation

         a = v² / r

angular and linear velocities are related

         v = w r

we substitute

          a = w² r

In the exercise they indicate the angular velocity w = 1 rev/min, let's reduce to the SI system

          w = 1 rev / min (2pi rad / 1rev) (1min / 60s) = 0.105 rad/ s

let's calculate

          a = 0.105² 50.0

          a = 0.55 m / s²

miss Akunina [59]
The total work done by the electric field on the charge is given by the scalar product between the electric force acting on the charge and the displacement of the charge:
W=F d cos \theta
where the force is F=qE, d=0.556 and \theta=55.2^{\circ}. Using the value of q and E given by the problem, we find
W=qEdcos\theta = 6.39\cdot10^{-5}J

A bicycle is traveling north at 5.0 m/s. The mass of the wheel, 2.0 kg, is uniformly distributed along the rim, which has a radi
andreev551 [17]

Answer:2

Explanation:

Given

Velocity of bicycle is 5 m/s towards north

radius of rim r=20 cm

mass of rim m=2 kg

Angular momentum \vec{L}=I\cdot \vec{\omega }

I=mr^2=2\times 0.2^2=0.08 kg-m^2

\omega =\frac{v}{r}=\frac{5}{0.2}=25 rad/s

L=0.08\times 25=2kg-m^2/s  

direction of Angular momentum will be towards west

Distance between the two place is 35 kilometers . If two persons start running towards each other from these two place with a sp
pashok25 [27]

The first person = A

The second one = B

velocity of A = 3 km / h

velocity of B = 4 km / h

Distance of A = 3t

Distance of B = 35 - 4t

At what time do they meet?

3t = 35 - 4t

7t = 35

t = 5 hours

7 a.m. + 5 hours = 12 p.m.

5) A parallel series electric blasting circuit consists of 6 branches of 8 caps each. Cap legwire length is 28 ft. The cap circu
andrezito [222]

Answer:

Minimum DC current = 9 Ampere

Voltage = 74.862 V

Explanation:

Here in this questions three resistors are used in series

Resistance of cap circuit

R_1 =\frac{ 8* 2.3}{6} \\R_1 = 3.067

Here 2.3 is the resistance per cap

Resistance of bus wire

R_2 = \frac{50 * 4.02 }{1000} \\R_2 = 0.201

Where 4.02 is the resistance per 1000 feet of bus wire of gauge 16

Resistance of firing line

R_3 = \frac{(2*1000)* 2.525}{1000} \\R_3 = 5.05

where 2.525 is the resistance per 1000 feet of bus wire of gauge 14

Total resistance is equal to

R = R_1 + R_2 + R_3\\R = 3.067 + 0.201 + 5.05 \\R = 8.318

Current in firing line is equal to

1.5 * 6\\= 9

Voltage is equal to product of resistance and current

= 9 * 8.318\\= 74.862
