A man with a mass of 60 kg rides a bike with a mass of 13 kg. What is the force needed to accelerate the bike at 0.90 m/s2?
Scrat [10]
The total mass of the things on the road is 60 + 13, which is 73kg.

mass • acceleration = F

73 x 0.9m/s^2 = 65.7N

F = 65.7 N

A rectangular coil with 50 turns of conducting wire and a total resistance of 10.0 Ω initially lies in the yz-plane at time t =
castortr0y [4]

Answer:

a) 43.20V

b) 2.71W/s

c) 40.25s

d) 7.77Nm

Explanation:

(a) The emf of a rotating coil with N turns is given by:

emf=NBA\omega sin(\omega t)

N: turns

B: magnitude of the magnetic field

A: area

w: angular velocity

the emf max is given by:

emf_{max}=NBA\omega=(50)(1.80T)(0.200m*0.100m)(24.0rad/s)\\\\emf_{max}=43.20V

(b) the maximum rate of change of the magnetic flux is given by:

\frac{d\Phi_B}{dt}=\frac{d(A\cdot B)}{dt}=\frac{d}{dt}(ABcos\omega t)=AB\omega sin(\omega t)\\\\\frac{d\Phi_B}{dt}_{max}=(\pi(0.200*0.100))(1.80T)(24.0rad/s)=2.71\frac{W}{s}

(c) emf(t=0.050s)=(50)(1.80T)(0.200m*0.100m)(24rad/s)sin(24.0rad/s(0.050s))\\\\emf(t=0.050s)=40.26V

(d) The torque is given by:

\tau=NABIsin\theta\\\\NAB\omega=emf_{max}\\\\\tau=\frac{emf_{max}}{\omega}\frac{emf_{max}}{R}\\\\\tau=\frac{(43.20V)^2}{(24.0rad/s)(10.0\Omega)}=7.77Nm

Find the net work done by friction on the body of a snake slithering in a complete circle of radius. The coefficient of friction
Tamiku [17]

Answer:

C. 0 J

Explanation:

When an object moves in a circle, friction provides the centripetal force. Hence, it is acting towards the centre of the circle. The displacement of the object is tangential to the circle at the point of interest. Hence, the angle between the frictional force and the displacement is 90°.

Work done is given by

<em>W</em> = <em>Fd</em> cos <em>θ</em>

where <em>F</em> is the force, <em>d</em> is the displacement and <em>θ</em> is the angle between them.

<em>W</em>  = <em>Fd</em> cos 90° = 0 J

Hence, the work done by friction is 0 J.

How does acceleration due to gravity changes wit depth?
ivann1987 [24]

Decreases

Explanation:

The acceleration due to gravity on a body decreases with depth.

Acceleration due to gravity is the change in velocity with time of a body as result of the pull of gravity or gravitational force.

  • The acceleration due to gravity tend to pull all bodies to the center of the earth.
  • As body moves away from the center of the earth, the pull becomes very more and acceleration increase.
  • But when a body approaches the center of the earth, the acceleration reduces.
  • At depth, the acceleration due to body of a body begins to decrease.
